A request for attendance and participation in a joint Assembly of First Nations (AFN)/Health Canada review of the Non-Insured Health Benefits (NIHB) program was received in October, 2016. The CAO indicated to AFN that it was pleased to be consulted as a stakeholder in the NIHB program going forward. Since the disbursement of this correspondence, there has been no further contact with AFN or NIHB. The CAO is grateful to Dr. Michael Patrician for his many years of service as treasurer. Dr. Patrician has kindly given the CAO an opportunity to transition this role to the new incoming treasurer, Dr. Don Johnston. Dr. Johnston will officially assume the role at the Annual General Meeting in September of 2017.

At the ad-interim meeting on March 4, 2017, The Canadian Dental Association (CDA) President, Dr. Randall Croutze, discussed the ongoing initiatives at the CDA including the taxation of health benefits, Secure Send, CDSPI, and the management of the influx of internationally trained dentists/specialists.

The federal government had proposed the possibility of imposing taxation on health benefits, including dental benefits. The CAO, along with other dental specialties, dental regulators and the CDA successfully lobbied the federal government away from this potential policy. In February, 2017, the Prime Minister of Canada announced in the House of Commons that his government would not tax health benefits.

The 69th Annual Scientific Session of the CAO will be held in the vibrant city of Toronto, Ontario. This year’s theme, “Controversies in Orthodontics”, is something that providers experience daily when we blend the art, science and technology of orthodontics. The Board of the CAO hopes that these sessions will permit one to assimilate the evidence presented and to take home some impartial recommendations for clinical practice. The CAO Conference and Scientific Session Committee has been hard at work to put together a first-rate program, including tremendous scientific and lifestyle educational opportunities. The social events planned throughout the weekend will highlight all that Toronto has to offer. Connecting and networking with friends (old and new) and colleagues around science, education and social events is what makes the Canadian Association of Orthodontists meeting so special.

While at the conference, feel free to reach out to share your thoughts with any board members of the CAO, and then continue the involvement through your regional membership upon your return home.

It has been a privilege to serve as President of the CAO this year.

Message du président Une invitation à assister et à participer à une Assemblée paritaire des Premières Nations (APN)/Santé Canada, visant à se pencher sur la révision du Programme de services de santé non assurés, nous est parvenue en octobre 2016. L'ACO a indiqué à l'APN que l'Association appréciait le fait d'être consultée à titre d'intervenant au futur programme. Suite à la réception de cette correspondance, il n'y a eu aucun autre contact, ni avec l'APN, ni avec le Programme de services de santé non assurés.

L'ACO désire exprimer sa gratitude au Dr Michael Patrician pour ses années de service à titre de trésorier. Dr Patrician a généreusement offert à l'ACO l'occasion d'assurer la transition et l'intégration du trésorier entrant, Dr Don Johnston. Dr Johnston acceptera officiellement le rôle de trésorier à l'Assemblée générale annuelle, en septembre 2017. À l'occasion de la réunion intérimaire du 4 mars 2017, Dr Randall Croutze, président de l'Association dentaire canadienne (ADC) a ouvert la discussion sur les initiatives en cours à l'ADC, incluant l'imposition d'une taxe sur les services d'assurance-maladie, l'ExpédiSécur, le CDSPI, ainsi que la gestion de l'arrivée au pays de dentistes/spécialistes formés à l'étranger.

Le gouvernement fédéral a avancé la possibilité d'imposer une taxe sur les services de santé, incluant sur les soins dentaires. À l'instar des autres associations de spécialistes en soins dentaires, des organismes de réglementation en matière de soins dentaires et de l'ADC, l'ACO est intervenue avec succès auprès du gouvernement fédéral, pour écarter la politique envisagée. En février

2017, le Premier Ministre du Canada a annoncé à la Chambre des Communes que ce gouvernement ne procéderait pas à l'imposition d'une taxe sur les soins de santé.

La 69e Réunion scientifique annuelle de l'ACO se tiendra dans la belle ville animée de Toronto, en Ontario. Le thème de cette année, Les controverses en orthodontie, est un sujet auquel nous sommes confrontés en tant que fournisseurs de soins où s'entremêlent l'art, la science et la technologie sur une base quotidienne. Le Conseil d'administration de l'ACO espère que cette réunion vous permettra de prendre connaissance des éléments de preuves présentées, et de repartir avec des recommandations impartiales pour votre pratique clinique. Le Comité scientifique et des conférences de l'ACO a travaillé sans relâche pour établir un programme de premier ordre, incluant de fantastiques occasions de formation en matière de sciences et de mode de vie. Également, les activités sociales prévues pour ce week-end mettront en valeur les attractions touristiques de la ville de Toronto. Cette réunion exceptionnelle de l'Association canadienne des orthodontistes est l'occasion rêvée pour rencontrer vos amis (anciens et nouveaux) et réseauter avec des collègues, dans un cadre portant sur les sciences, les formations et les activités sociales. À l'occasion de cette réunion annuelle, n'hésitez pas à venir rencontrer les membres du Conseil d'administration de l'ACO, afin de partager votre opinion sur notre profession. De retour à la maison, nous vous invitons à poursuivre votre implication, par l'entremise de votre adhésion au niveau régional.

Soyez assuré que ce fut un privilège pour moi d'agir à titre de Président de l'ACO cette année.

The Canadian Foundation for the Advancement of Orthodontics (CFAO) Silent Auction held during the Scientific Session in Charlottetown generated $5,695.00. Thank you again to the individuals and the component associations that donated items to the auction.

The CFAO is committed to continuing with the Silent Auction into the coming years and donations to the auction have been included in the contracts for the upcoming venues.

Congratulations to the organizing committee on another successful Student Research Symposium at the 2016 Scientific Session. The CFAO was pleased to offer its financial support to this worthwhile event.

It has been a busy time for Smiles4Canada. In September, the program expanded with chapters forming in British Columbia, the Prairie Provinces and Ontario. Letters were sent to stakeholders in these areas through mailings to the members.

In January, the CFAO participated in a radio interview with CBC Halifax. The interview featured one of the first patients to receive treatment through the program. Please make a point of listening to the interview as the family’s story is very powerful. The story was posted on the CBC website and generated a huge amount of positive exposure for the program.

As of April 23, 2017, there have been approximately 74,000 social media shares of the story. This exposure has been favourable for the profession, CAO members and orthodontic treatment in general.

All of the exposure has generated a significant increase in applications to the program. As of April 23, 2017, there have been 153 completed applications to the program. Thirty-nine of these applications have been accepted and matched to participating orthodontists. An additional 92 applications are under review by the Regional Committees.

Thank you to Alison Nash, Shannon Whitteker, Avi Goldberg, Gordie Organ, Sunny Leong, Jeff Stewart, all the Regional Committee members and especially to all the orthodontists who have agreed to provide treatment through the program.

Committee Reports CFAO Treasurer Report As of December 31, 2016, the net revenue for the Canadian Foundation for the Advancement of Orthodontics (CFAO) was - $6,733.77. The total current assets are $344,136.22. Total member equity is $209,591.25. The 2016 disbursements from the Foundation have been completed. The disbursement quotient for 2016 was $10,364.17. The disbursement quotient for 2017 is estimated to be $10,739.00.

Member equity and total current assets have decreased in response to the increase in expenditures arising from the Smiles4Canada program. The Board will continue to monitor the potential need for funds that may arise in the future and to reassess novel fundraising initiatives as a counteractive measure.

Since the CFAO spent $26,406.00 in 2015 on charitable activities, it has a carry-forward disbursement excess of $16,604.05. This disbursement may be carried forward for five years. The Board will have to decide, if and when, it plans to use this excess contribution.

The match program will continue through the next sixteen months, after which the AAO will reassess the program. Currently there is no additional information available from the AAO for the CAO to make any future plans regarding the CAP.

GST/HST Report Dr. Michael Patrician Treasurer Email: drpatrician@bellnet.ca There have been no new communications with the Canada Revenue Agency (CRA) regarding the Input Tax Credit (ITC) system for GST/HST in Canada.

In November and December of 2016, the CAO was audited

by CRA for it’s GST/HST ITC returns. No challenges or changes to the returns were found by CRA. There continue to be CRA audits of orthodontic offices in Canada but the frequency of the audits has decreased. The member e-blast and joint CRA/CAO question and answer document appears to have been of benefit.

Email: stuart.smith4@sympatico.ca The Consumer Awareness Program (CAP) has been running across the country in English since early October, 2016. It continued to run until the end of May, 2017. The French version has been in place since November, 2016. Three quarters of the funds were allocated to the digital campaign and the remainder to television advertisements. Recently, the CAO logo graphics were changed for both digital and television advertisements. The CAO has maintained a presence on the “Red Carpet” programs prior to award shows. This year the CAO placed advertisements during the first, second and third rounds of the NHL playoffs. This exposure was intended to broaden the target audience that traditionally had been females between the ages of 25 and 50.

The CBC/SRC homepage takeovers on Wednesday, November 10, 2016, were a success. The homepages had 2.4 million hits on the CBC site that day producing approximately 7,000 hits on the CAO/AAO sites arising from Canada.

The successful university researcher and resident oral and poster programs are of huge benefit to all of the graduate programs. The financial assistance to the residents in support of their attendance at the CAO Scientific Session, in order for them to permit showcasing of their research at a national forum amongst peers and colleagues, is highly appreciated.

After considerable discussion, Blackjet, Evans Hunt and Jelly were invited to submit video presentations to the committee on January 27, 2017.

The committee was impressed with the bold, innovative and edgy nature of the presentation by Blackjet and has proposed this firm as the one to be contracted by the CAO Board for the purposes of marketing and promotion.

CDSA Report Dr. Mike Wagner CDSA Liaison Email: wagner.cao@gmail.com The most recent CDSA AGM was Thursday, April 20, 2017, at the Chateau Laurier, in Ottawa, Ontario. Dr. Christina McCord, of the Canadian Association of Oral and Maxillofacial Pathology/Oral Medicine (CAOMP/OM), joined the executive as Secretary Treasurer.

Dr. Frank Hohn of the Canadian Association of Oral and Maxillofacial Surgery (CAOMS), is the current Vice-President and Dr. Jean-Pierre Picard of the Canadian Association of Prosthodontists (CAP) is the current President.

The CDSA Travel Award criterion was uploaded to the website and was added to the new Policy and Procedures manual. The award will fund $1000.00 for a graduate and an undergraduate student to attend the Annual Meeting of the International Association for Dental Research (IADR). The 2016 travel award recipient was Dr. Rana Tarzemany of the University of British Columbia, Discipline of Periodontics. There were no qualified undergraduate applications. The 2017 IADR meeting was held March 25 to 27, 2017, in San Francisco, California.

CDSA has written to the Assembly of First Nations (AFN) to request that the CDSA and all individual specialties be contacted in regard to proposed changes to the NIHB program.

Smaller specialties support the CDSA in this initiative but have not requested an invitation to the table on an individual level as they are not primary providers to this program.

Representation has been made to the Executive of the Canadian Dental Association (CDA) that CDSA has no affiliation with the Canadian Dental Specialties Organization (CDSO).

No further action has been taken on this issue by the CDSA other than to verify that the CDSO is not a registered corporate entity within the province of Ontario.

Sedation guidelines across the country are being reviewed following an unfavorable outcome involving a patient in Alberta and a trained Dental Anesthesiologist. Stakeholders within

Committee Reports the CDSA will advocate to regulatory bodies to develop equal sedation standards across the country.

A letter writing campaign was encouraged for all the component specialties as a result of the proposed federal taxation of health benefits. As of February 2017, this campaign has proven to be successful as the Prime Minister of Canada has recently indicated that his government has no plans to tax health benefits of any sort, inclusive of dental benefits.

dontic Health Day and posters were handed out. Materials, such as logos and posters, to use to celebrate that day will be available from the website and more will be added as they are developed. May 15, 1995, was the date the Charter of the WFO was signed. In 2020 there will be a special celebration for the silver jubilee. WFO is now on Wikipedia and has a Facebook page, with other forms of social media currently under consideration.

WFO Liaison Report Dr. Amanda Maplethorp WFO Executive Committee Email: a_maple@shaw.ca In March 2017, Dr. Vinod Krishnan of Trivandrum, Kerala, India was selected as the new Editor in Chief of the Journal of the World Federation of Orthodontists. He began his term April 1, 2017, by selecting a very strong editorial board including Associate Editors Jae Hyun Park, Arizona, Carlos Flores-Mir, Alberta, Shin-Jae Lee, Korea and Carlalberta Verna, Switzerland. His Consultant Editors include David Turpin, Washington, Jorge Faber (Immediate Past Editor in Chief JWFO), Brazil and Jyothindra Kumar, India.

The WFO Executive Committee met April 21, 2017 in conjunction with the AAO Annual Session in San Diego. The Albanian Association of Orthodontists was accepted to the WFO and several other applications from organizations are pending receipt of documents.

The WFO website home page is under revision to make it more active and mobile-friendly. The WFO Gazette will now be available online instead of in print and therefore will be available to members much quicker in a technology-friendly format.

Dr. Robert Kinniburgh represented the CAO at the WFO Breakfast Meeting in San Diego on April 23, 2017. The 10th IOC meeting in 2025 will be held October 8 to 11 in Rio de Janeiro, Brazil.

Webinar Update Dr. Gerry Zeit The 2016 fall webinar was presented on Thursday, November 24, at 8:00 EST. The speaker was Lianne Chan, a physiotherapist with extensive experience and interest in temporomandibular dysfunction. Her presentation was entitled “TMJ Disorders: A Physiotherapists Perspective”. It was enlightening to hear how another discipline approaches this common and wide ranging collection of symptomologies. The webinar will be available for review on the CAO website until November, 2017.

The CAO was approached by Don Millar (Cerum) to have Dr. Luis Carriere present a webinar in February, 2017. This webinar fit with the CAO’s desire to increase the number of annual webinars. Unfortunately due to scheduling constraints, this webinar was not secured. The spring webinar featured Dr. Bruce McFarlane on March 29th, 2017 at 8:00 pm EST. Dr. McFarlane was able to share his experience with Dr. Carriere’s Motion Appliance in a “fast paced, entertaining hour”. Thank you to Cerum for their support and sponsorship of this presentation.

As always, many thanks to the entire CAO staff and especially to Alison Nash and David Petrie for organizing and hosting the webinars.

I remain interested in feedback and ideas or suggestions regarding topics and possible speakers for future webinars.

It was announced that henceforward, May 15 will be Ortho-

CAO Insurance Guidelines History: 25 years ago, the CAO battled with the insurance companies over the use of codes for orthodontic specialists.

This fight lasted 5 years and the CAO won so that codes were abolished for orthodontic specialists. The major achievement of this agreement was the establishment of the precedent that, as specialists, there would be no requirement to submit records or treatment details to the insurance companies.

Insurance predetermination has recently become more complex. Plans are adopting new “pockets” of coverage instead of one umbrella of orthodontic coverage. There may be more coverage if Interceptive Phase and Full Phase is defined in the predetermination, as some carriers have begun segmenting plans between Interceptive phase and Full phase Orthodontic Treatment.

The key to successful submission of pre-determination forms lies in accurately and completely filling out the form as prescribed by the CAO guidelines.

An example of this form (fictional patient, insurance policy holder and information) is attached.

• Complete all portions of the form.

the patient they have coverage, but it is actually dental coverage for “medical necessity”. Orthodontics will never be covered under this section unless it can be deemed a “medical necessity” as determined by the insurance company.

2. Make sure you document all conversations with the insurance company and obtain the representative’s name and number. Remember that you are speaking to a call center employee with limited dental/orthodontic knowledge.

3. Remind them that in accordance with guidelines from CLHIA (Canadian Life and Health Insurance Association) no codes, records or treatment plans are required for orthodontic specialists.

4. If this is not sufficient, ask to speak to a supervisor and repeat steps 1-3 with the supervisor.

If the insurance company is still not being cooperative, send all information including a copy of the CAO insurance form, any correspondence from the insurance company, a copy of the patient’s insurance policy and documentation of phone conversations to the CAO. The Insurance Committee may be able to help.

Direct Billing/Assignment

• Start date is optional, but can be filled if known.

• Description of the condition has always been optional, but if you fill it in, it generally makes life easier. The CAO advises members to fill this section using generic terms such as: anterior crossbite, mandibular retrognathia, deep overbite, maxillary crowding etc. You may also include a phase of treatment i.e. Interceptive, Phase I, Comprehensive Orthodontics

The CAO does not recommend direct billing by orthodontists as the use of general dentist codes is required. The orthodontic codes that exist are for use by general dentists only. The more orthodontists that use dental codes, the more difficult it becomes for the CAO to reach the objective of digitization of insurance by a specialty office.

• DO NOT – use classifications such as Class I, Class II etc.

CDAnet

• Filling out the financial information is crucial. There is enough flexibility built into this section to accommodate most payment options.

• The Additional Explanatory Comments are optional, but it doesn’t hurt to add the illustrated comment.

• Never provide the appliance type in any predetermination or treatment details such as extractions, surgery, etc.

If you are ever asked by an insurance company for records, codes or a treatment plan. Please follow these steps: 1. Ensure that the patient/parent does indeed have orthodontic coverage. In most plans, it is provided as a separate entity from regular dental coverage. Some companies will tell

CAO Bulletin • SPRING 2017

The CAO has been working diligently for the past two years along with several other associations including the CDA to figure out a platform for pre-determinations. The use of a single code for predetermination is what the CAO is working toward.

The first application has been rejected but the CAO continues to work toward this objective.

Currently, you can submit over CDAnet with codes (as a general dentist) but of the 68 insurance providers on CDAnet, only 15 will reply with the amount of coverage. The remaining 47 will just respond that they received the request and will conventionally mail the info to the patient.

The Consumer Awareness Program (CAP) is consuming most of the attention of the BCSO board of late. The efforts of Athorn and Clark have been reviewed. Dr. Todd Moore has been in contact with an American firm known as Sutton Group who is working with both Texas and California state associations and now Centrifuge Media to update and to make the BCSO website more user-friendly for the public and for BCSO members.

The intent is to move away from Google ad words and to focus in on education and information. Dr. Moore is in the process of forming a BCSO marketing committee that will ensure continuity of the CAP message by minimising the learning curve for each new line member. Hopefully, in Alberta, the committee will receive contributions from the different regions of the province in order to ensure that the message is delivered effectively where needed. Dr. Moore also aims to enhance the positive message that the general practitioner is an important part of the patient’s overall health and that he or she will conduct regular assessments, cleaning and restorations following the completion of orthodontic treatment by a certified specialist.

Dr. Moore is attempting to position the BCSO for the future through improved engagement between orthodontists, realising we are stronger together than fragmented. We need a strong relationship province-wide to promote together as specialists. With increased membership we can tackle the issues all orthodontists are going to face in the future.

At the University of Manitoba, the Graduate Orthodontics Department, three incoming residents hail from Quebec, Ontario and Australia. All four of the senior residents, as well as faculty member Dr. Fabio Pinheiro, were successful in passing their spring 2016 RCDC examinations. At the CAO meeting in Charlottetown, the Graduate Orthodontics Department celebrated its 50th anniversary. Congratulations to the department for its success!

The MOS president, Dr. Bobby Ward, met with the Manitoba Dental Association (MDA) Executive Director, Dr. Rafi Mohammad and the Registrar, Dr. Marcel von Woensel, in November 2016, to advocate for the MDA to be proactive in the management of misleading advertising by general dental colleagues. Following the meeting, according to a report by Dr. Ward, the MDA did not indicate specific plans for action.

Ontario Dr. J. Eric Selnes Email: str8smiles@sympatico.ca The Ontario Association of Orthodontists (OAO) had positive net revenue this year with the help of the Scientific Session. The advertising campaign with the AAO started in the summer, so half was budgeted for 2017, a total of a $75,000 commitment over three years. The OAO will spend about $30,000 of its own funds on the CAP program in 2017. The total spent is $60,000, with the remaining half forthcoming from the AAO. In addition, the AAO will match costs on the OAO web design.

The OAO investigated if it should or should not be charging HST on OAO activities, based on the ODA having to retroactively remit HST arising out of a CRA investigation.

The Ontario advertising campaign is going strong. Ontario is spending approximately $4,500 per month for the on-line campaign. The non-grant account is generating 10,000 visitors to OAO website and 16 percent used locator, while the grant account is generating 5,500 visitors to OAO website and 8 percent used locator. There have been 1,440 doctor locator clicks since June 2016. The OAO has received $11,000 in free advertising thru Google with the grant account. Now with decent traffic to the website, the OAO enhanced and upgraded the look of the website home page. The goal was to have the new page by February 28, 2017 and it was presented to the membership on March 30, 2017.

Dr. Dale Anne Featheringham, President of the Great Lakes Association of Orthodontists (GLAO) presented to the OAO members on March 30, 2017.

University of Alberta EMERGENCIES AND COMFORT LEVELS WITH COMPLIANCEFREE FIXED CLASS II CORRECTORS DURING CLASS II MALOCCLUSION TREATMENT: A SYSTEMATIC REVIEW Author: Ashley Phuong*; Carlos Flores-Mir (Supervisor) Objective: To qualify and quantify the emergencies and comfort levels associated with compliance-free fixed Class II correctors during Class II malocclusion treatment.

Methods: A systematic search of several electronic databases (Medline, PubMed, Embase, and Web of Science) was conducted until May 2016, as well as a limited grey-literature search (Google Scholar). Prospective and retrospective human studies that used a compliance-free fixed Class II appliance in a non-extraction and non-surgical approach were selected. Two authors independently reviewed and extracted data from the selected studies. Risk of bias was assessed.

Results: Eleven studies satisfied the inclusion criteria. The patients’ mean age ranged from 10.3 – 15 years and the fixed Class II corrector treatment duration ranged from 3.8 – 12 months. The studies involved variations of the Herbst and Forsus only. The rate of emergency appointments ranged from 22.28% of patients treated with a stainless steel crown Herbst to 88% of patients treated with a removable mandibular acrylic splint Herbst. The main area of discomfort was soreness in the cheek. There was a lack of standardized reporting methodology between studies.

Conclusions: Emergencies associated with fixed Class II correctors are frequent and differ with appliance design. Future research should examine other Class II correctors. A standardized method for reporting emergencies must be developed to allow for comparison of different Class II correctors.

This additional information may be useful to clinicians when selecting a Class II corrector.

University of Alberta 3D EVALUATION OF MOLAR AND CANINE BUCCOLINGUAL INCLINATIONS IN MAXILLARY TRANSVERSE DEFICIENCIES. Authors: Dr. Manuel Lagravere-Vich (Supervisor), Dr. Carlos Flores-Mir, Dr. Martin Palomo Objective: Propose a novel 3D method for measurement of molar and canine buccolingual inclinations in maxillary transverse deficiencies and compare it to the CWRU transverse analysis.

Methods: Pre-treatment CBCTs of 60 patients with different degrees of maxillary transverse deficiencies were assessed using two methods to evaluate maxillary and mandibular molar and canine buccolingual inclinations. A novel method was proposed that used the 3D potential of DICOM images with a 3D skeletal maxillary reference plane and a software algorithm to determine 3D angular measurements through the true buccolingual plane of each tooth. These findings were compared to the CWRU transverse analysis that used coronal slices for 2D buccolingual angular measurements. Each method was assessed for intra- and inter-examiner reliability.

Results: Both techniques demonstrated excellent reliability (ICC>0.91). There was a statistically significant difference for all measured teeth between techniques. Using a clinically significant difference of 10 degrees, only maxillary canine buccolingual inclinations showed a clinical difference between both methods.

Conclusion: The clinical difference between methods for maxillary canines can be attributed to the use of different reference planes and different approaches to the long axis of the teeth.

However, a new reliable method for 3D analysis of buccolingual inclinations was developed and shown that it did not differ clinically from the CWRU transverse analysis for all teeth except maxillary canines. Further studies are required to confirm the accuracy of either analysis, to develop norms and to assess its clinical application.

University of Alberta OBSTRUCTIVE SLEEP APNEA AND MANDIBULAR CORTICAL THICKNESS: A RETROSPECTIVE STUDY

Authors: Gaetana Rauccia; Camila Pacheˆco-Pereirab; Maryam Elyasic; Fabrizia d’ Apuzzod; Carlos Flores-Mire; Letizia Perillof

1

Background: This retrospective study aimed to identify which dental and/or cephalometric variables were predictors of longterm mandibular dental arch stability in patients that underwent treatment with transpalatal arch and lip bumper during mixed dentition followed by full fixed appliances in the permanent dentition.

Methods: Thirty-one patients were divided into stable and relapse groups based on the long-term presence or not of relapse. Intercuspid, interpremolar and intermolar widths, arch length and perimeter, crowding and lower incisor proclination were evaluated before treatment (T0), post-lip bumper treatment (T1), post-fixed appliance treatment (T2), and a minimum of 3 years after full fixed appliances’ removal (T3). Logistic regression analyses were performed to evaluate the effect of changes between T0 and T1, as predictive variables, on the occurrence of relapse at T3.

Results: The model explained 53.5% of the variance in treatment stability and correctly classified 80.6 % of the sample.

Of the seven prediction variables, intermolar and interpremolar changes between T0 and T1 (p=0.024 and p=0.034 respectively) were statistically significant. For every millimeter of increase in intermolar and interpremolar widths there was an increase of 1.52 and 2.70 times in the odds of having stability.

There was also a weak evidence for the effect of sex (p= 0.047).

Conclusions: The best predictors of long-term mandibular dental arch stability after treatment with a lip bumper followed by full fixed appliances were intermolar and interpremolar width increases during lip bumper therapy. The amount of relapse in this crowding could be considered clinically irrelevant.

3 Department of Pediatrics, Pritzker School of Medicine, Biological Sciences Division, The University of Chicago, Chicago, Illinois 60637, USA. Purpose: To evaluate the cortical thickness of the mandible on dental panoramic radiographs of children diagnosed with obstructive sleep apnea (OSA) and children with no reported sleep disorders. Mandibular cortical thickness has been strongly linked to skeletal bone density.

Methods: Mandibular cortical thickness measurements were retrospectively assessed using mandibular cortical width index (MCW) and Panoramic mandibular index (PMI) obtained from panoramic images of 27 OSA PSG diagnosed children between 2009 and 2016. Following a matching process based on age and sex, 81 children with no reported sleep disorders (controls) were selected. Factorial analysis of variance was used to compare MCW and PMI measurements between the 2 groups.

Results: ICC results for reliability assessment were found to be excellent (ICC values were above 0.9). No significant differences were found based on sex (p>0.05), therefore both sexes were evaluated together. An increase in MCW and PMI values associated to aging in OSA (MCW, R=0.72, p <0.01; MCI, R=0.55, p <0.01) and control children (MCW, R=0.66, p <0.01; MCI, R=0.57, p <0.01) was identified. MCW and PMI mean values were significantly lower in OSA children (MCW=3.1±0.06mm; PMI=0.32±0.04) compared to control children (MCW=3.6±0.06mm; PMI=0.38±0.05).

Conclusions: Findings of this study indicate that children with OSA have thinner mandibular cortex (based on MCW and PMI measurements) compared to children with no reported sleep disorders. This study represents the first clinical evidence suggesting that children with OSA are at higher risk to develop bone disease (such as osteopenia and osteoporosis) in the future.

University of Manitoba GROWTH MODIFICATION VERSUS SURGERY FOR SEVERE CLASS II MALOCCLUSIONS

Authors: Ponce-Garcia C, Hernandez I, Flores-Mir C (Supervisor)

Authors: William A. Wiltshire, BChD, BChD(Hons.), MDent, MChD(Orth), DSc, FACD, FRCDC

AIM: To methodically synthesize the available literature concerning the impact of breastfeeding on sleep disordered breathing in young children.

METHODS: Eligibility criteria: Prospective and retrospective cohorts, case-controls, cross-sectional studies and clinical trials that evaluated the association between infant’s feeding methods and pediatric sleep disordered breathing were included. No restrictions were applied regarding language, year of publication, sex, or ethnicity. We excluded studies that included patients with severe craniofacial anomalies, genetic syndromes, and/or neuromuscular diseases.

Information Sources: A systematic search of five electronic databases (Embase, Medline via OVID, Web of Science, LILACS and SCOPUS) was carried. All searches were inclusive until May 11, 2016.

Introduction: Growth modification(GM) of severe Class II malocclusions in growing patients may serve to reduce or even eliminate the need for orthognathic surgery.

Aim of the study: To evaluate the clinical outcomes of a growth modification treatment protocol in patients with severe Class II malocclusions who refused a surgical option Subjects and methods: Fourteen skeletal Class II retrognathic patients (ANB= 5° - 10°) with severely enlarged overjets (8mm – 10mm) and proclined upper incisors were treated with a van Beek HGA followed by full-fixed appliances and matched with non-growing patients with similar growth patterns whom were treated with full-fixed orthodontics and surgery.

Continued…

Risk of bias Assessment: The Newcastle-Ottawa Scale was used for quality assessment.

RESULTS: Included studies: From the 70 articles initially retrieved and reviewed only 10 studies fulfilled the criteria to be finally included in this review.

Synthesis of results: While seven of the selected studies reported a positive significant association between breastfeeding and sleep breathing disorders, the remaining three studies did not show any association.

DISCUSSION: Strengths and Limitations of evidence: The main methodological limitation was related to data collection on infant feeding methods. All of the identified studies used a validated questionnaire to investigate if children were breastfed. However, some of them were retrospective and did not specify duration and/or exclusivity.

CONCLUSION: The cumulative evidence is non-conclusive that exclusive breastfeeding is associated with decreased sleep breathing disorders in children.

CFAO Graduate Student Posterboards RESULTS: GM varied from 4 – 11 months. Molar relationship, overjet, overbite and lip competence were all reduced to within normal limits. Total treatment time varied from 19 – 30 months(x= 24). Patients with GM were deemed not to require surgery after Phase 1 or, were satisfied with the aesthetics and opted not to pursue that option following GM. Patients in the surgical control group often did not achieve the aesthetics and function attained in the GM group.

CONCLUSIONS: Despite current RCT data, GM seems to present a viable alternative to surgery in selected, compliant, growing Class II patients, even in severe dysplasias, within a 2 year time frame. Surgery should not be considered as a sine qua non for every Class II malocclusion, and individual variation and patient/parent concerns and preferences must be taken into account in clinical decision-making by the orthodontist in pain when using this device. Tooth movement is accelerated.

The strongest correlation was found between MMB Wits and ANB angle in the open bite group (r=0.74).

CONCLUSIONS: The Wits appraisal using the MM bisector is a valid indicator of the sagittal discrepancy. The MMB Wits had a higher correlation coefficient to the ANB angle than the FOP Wits, further reinforcing its validity. Caution must be exercised in trying to relate any of Wits appraisal to the gold standard of the ANB angle.

University of Manitoba VALIDITY OF THREE REFERENCE PLANES IN THE ASSESSMENT OF OPEN BITE AND DEEP BITE SUBJECTS. Authors: Dr. Virginie Provencal Dr. William A. Wiltshire (BChD, BChD (HONS) M. Dent, MChD(Orth); DSc, FACD, FPFA, FRCD (C) Dr. Kris Row (BA, DDS, M Sc.) Dr. Catalena Birek (DDS, PhD, FRCD (C)) OBJECTIVES: The purpose of this retrospective study was to evaluate the reliability and accuracy of three anteroposterior reference planes applied in the Wits analysis.

MATERIALS AND METHODS: A retrospective chart review was undertaken on 150 subjects. Subjects were categorized into 3 groups based on the value of pre-treatment overbite; 50 normal (1-3 mm), 50 deep (more than 3mm) and 50 open bite (less than 1 mm) subjects. The maxillomandibular bisector (MMB) was used to evaluate the anteroposterior jaw discrepancy and compared to the Wits analysis and the ANB angular measurement using the bisecting occlusal plane (BOP) as well as the functional occlusal plane (FOP).

RESULTS: The correlations of the three Wits appraisals (FOP Wits, BOP Wits, MMB Wits) to each other were moderate to high ranging from 0.56 to 0.89. The strongest correlations were found between BOP Wits and MMB Wits in the open bite group (r=0.89). Moreover, the correlations of the three Wits appraisals (FOP Wits, BOP Wits, MMB Wits) to the ANB angle were low to moderate ranging from 0.39 to 0.76.

OBJECTIVE: To assess the dental and skeletal treatment and growth changes in growing Class II malocclusions with the van Beek Headgear Activator appliance followed by full fixed orthodontic treatment.

MATERIALS AND METHODS: The treatment group consisted of 40 growing patients (20 males, 20 females, mean age 11.8 +/- 1.3 years) with Class II malocclusions that met the inclusion criteria and were treated under the supervision of one instructor (W.A. Wiltshire) with a first phase of van Beek Headgear Activator followed by a second phase of full fixed orthodontic appliance treatment. Lateral cephalometric radiographs were taken for all subjects pretreatment (T0) and after the completion of the second phase of treatment (T2) and a subgroup of the treatment group had lateral cephalometric radiographs taken after the completion of the first phase of treatment (T1). Dental, skeletal and growth effects were assessed by sagittal, vertical, and angular cephalometric parameters.

RESULTS: Comparison of the cephalometric radiographs showed a decrease in ANB angle (T1 = -1.9º; T2 = -2.3º), Wits value (T1 = -2.1mm; T2 = -4.2mm), and overjet (T1 = 4.4mm; T2 = -5.9mm) with an increase in SNB angle (T1 = +1.1º; T2 = +1.4º) and Harvold difference (T1 = +3.9mm; T2 = +5.4mm).

CONCLUSIONS: The van Beek Headgear Activator was found to be an effective treatment modality in the correction of Class II malocclusions in growing patients.

OBJECTIVE: This retrospective longitudinal study aimed to analyze trends and quantitative differences in craniofacial morphology and facial growth patterns between non-syndromic Pierre Robin Sequence (PRS) and unaffected subjects.

METHODS: Characteristics of the maxilla, mandible and cranial base were examined at 6 years, 12 years and 18 years, using a comprehensive cephalometric analysis that focused on regional detail by means of internal and external landmarks.

Lateral cephalometric tracings of 43 Caucasian subjects with PRS treated at the Hospital for Sick Children were compared with age- and sex-matched Caucasian unaffected subjects from the Burlington Growth Centre archives. Between-group differences of craniofacial measurements were analyzed.

RESULTS: The PRS group had smaller cranial base lengths.

Their maxillas were smaller with shorter anterior maxillary height and remained retrusive throughout the period of active facial growth. Their mandibles were smaller in body length and height as well as ramal width and height and also remained retrusive throughout growth. The PRS group also displayed a vertical growth pattern as indicated by an increased gonial angle.

University of Western Ontario DEXAMETHASONE REGULATES GENE EXPRESSION INDUCED

BY THE MECHANOSENSITIVE P2X7 RECEPTOR IN OSTEOBLASTS Authors: Erin Eyer*, M Na, A Pereverzev, MW Grol, SJ Dixon Division of Graduate Orthodontics, Schulich School of Medicine and Dentistry, Western University Orthodontic tooth movement involves activation of osteoblasts and osteoclasts in response to mechanical forces. Extracellular nucleotides, released in response to mechanical stimuli, signal through P2 receptors in osteoblasts. P2X7 receptors are ATPgated cation channels implicated in mechanotransduction in bone. Corticosteroids such as dexamethasone exhibit anti-inflammatory effects and their chronic use has been linked to serious side-effects such as osteoporosis. We investigated gene expression following P2X7 receptor activation with benzoylbenzoyl-ATP (P2X7 receptor agonist) in osteoblast precursor cells in the presence or absence of dexamethasone. We hypothesized that dexamethasone inhibits the ability of ATP to stimulate the expression of anabolic (bone forming) genes in osteoblasts. We showed that benzoylbenzoyl-ATP stimulation of Ptgs2 and Dmp1 expression is indeed inhibited by dexamethasone. Thus, intracellular events following activation of P2X7 may be important in regulating osteoblast differentiation, maturation and eventual bone formation during orthodontic tooth movement. Dexamethasone may adversely affect these processes.

CFAO Graduate Student Posterboards University of Western Ontario QUALITY OF LIFE AND SUBJECTIVE OUTCOMES FOLLOWING MAXILLOMANDIBULAR ADVANCEMENT SURGERY FOR THE TREATMENT OF OBSTRUCTIVE SLEEP APNEA Authors: Michelle Watroba*, A Emanuele, R Bohay, M Shimizu, A Tassi Division of Graduate Orthodontics, Schulich School of Medicine and Dentistry, Western University OBJECTIVE: The aim of this study was to assess outcomes related to general quality of life, daytime sleepiness and functional sleep outcomes, functional outcomes of orthognathic surgery, and facial aesthetics in patients undergoing maxillomandibular advancement (MMA) surgery for the treatment of obstructive sleep apnea (OSA).

MATERIALS AND METHODS: This was a cross-sectional self-report study. A questionnaire was constructed using questions drawn from previously validated questionnaires. The survey was distributed to 25 patients who underwent MMA surgery for the treatment of OSA at LHSC in London, Ontario by a single surgeon between 2002 and 2013.

RESULTS: The survey results showed that MMA patients responded positively with respect to quality of life, snoring, functional sleep outcomes and daytime sleepiness, and facial aesthetics. Nineteen (86.4%) indicated that their sleep apnea symptoms have improved since the surgery. Eighteen (81.8%) reported neutral or positive changes with respect to facial attractiveness. Nineteen (86.4%) indicated that their overall quality of life has become better since having MMA. Most patients indicated that the surgery was worthwhile and would recommend it to others suffering from OSA. CONCLUSIONS: MMA surgery for the treatment of OSA appears to have an overall positive effect on quality of life, sleep outcomes, and aesthetic outcomes. The majority of patients found the surgery worthwhile. Orthodontic treatment in conjunction with MMA appears to enhance the subjective aesthetic outcomes of treatment.

Membership has its Privileges “I’d never be a member of a club that would have me as a member.”

They were trying to save the club from imminent demise.

Groucho Marks, 1949

As a kid, I ran a company that maintained sail boats at the Island Yacht Club in Toronto. It was the mid- eighties. A Republican actor was the president and the stock market was surging. At least that president didn’t launch cruise missiles over dessert, change policy on a whim, or accuse his predecessor of wire-tapping, but I digress. For once, the state of the nation is not the purpose of this piece.

A firm position on membership either defines a value that builds a base, or it ticks-off the establishment enough that it forces it to vote with their feet, leaving the organization to burn to the ground.

In the unfortunate case of the Island Yacht Club, it was the latter that transpired; literally and figuratively. You can read about the fire in old newspapers if you really want to.

Granted, there are differences between professional organizations and ritzy sailing clubs, but the issue of membership is consistent. Without a steady influx of new members plus a consistent solid membership base upon which to rely, the organization cannot sustain itself.

Everybody knows this. The key is to recognize a problem early enough to do something about it.

Eventually, I became a member of this sailing club in my own right. And the place was hopping. Then, slowly, steadily, for whatever the reasons, things began to change. One could feel it in the air, like a shift of the wind in the harbor. Long-term members began leaving the club and people began to talk.

I remember one annual meeting in particular that focused on membership. A wellknown periodontist from Toronto, stood up and lamented the club’s policy limiting the number of times his non-member adult children could visit as guests. The club board was adamant; either the kids joined the club, or they were exempt from the privileges of membership. A lively discussion erupted from the floor. It got ugly.

At the time, I was troubled. How could the board be so hard-hearted as to exclude the children of their own members? Looking back, from where I sit now, I see the method to their madness.

on the value of membership. The policies are firm. The terms are understood by all.

If you want the benefits that the club has to offer, you maintain your membership.

If young sailors want to use the club, they join as junior members after the age of sixteen, no exception. The membership base is strong and there is a steady influx of young members from a variety of diverse backgrounds. Today the club is over 100 years old and my money is on its surviving for years to come.

Today, I’m a member of a neighbouring sailing club. I often wonder why the new club is a success, while the other one failed woefully. They are literally a stonesthrow apart, made up of the same one percent, with a common interest at heart.

As a non-board member of the new club, I believe success is rooted in the club’s ability to sustain a solid young membership base and to build a culture based

With regards to organized orthodontics, I’m feeling that same funny feeling that I had as a kid, way back when the periodontist spoke his mind from the floor.

If you are reading this, and are (hopefully) a member of the CAO, then you need to know the facts. The membership base is starting to falter. Newer orthodontists aren’t joining but that’s not the crux of the problem. Multitudes of established members are not renewing their membership. Once the base falls below the critical mass, whatever that may be, there is going to be a real problem. We, as a profession in Canada, cannot let this happen.

Two things need to happen right now.

From the Editor Cont’d.

First, all members need to strongly encourage all non-member orthodontists to join. The Board does its best, but it needs the help of all members to ensure that the programs like the Consumer Awareness Program, brand marketing and insurance reforms can continue. The costs for all of these benefits are continually on the rise. Orthodontists who do not join receive the benefit, but pay none of the cost, while those who have joined (yes, you) pay an increasing proportion of these costs over time. That’s simply not right, nor is it sustainable.

Second, the Board must adapt and offer new initiatives to stabilize membership. The current structure of organized orthodontics was set up before the rise of the internet and social media. One used to need many layers of organization to ensure that information was disseminated to the masses. No longer. I know as much as The Donald does about what’s going on between North Korea and the United States with one click of the keyboard. Well, almost as much. Probably more. It is a small world after all.

Sometimes, it all seems like too much; too many organizations,

too many memberships and too many reminders. Wouldn’t life be simpler with just a single membership that serves everyone’s needs from the national down to the local level? I love the thought of writing a single cheque once a year that sees to all of my professional obligations. Whether or not this concept is something that can be explored remains to be seen, but to me, making things easier in a not-so-easy world is a real member benefit that would keep me coming back for years to come. How about you?

Yay Summer!
