Celebrating 30 years of technology: a 30-year s The visionary idea of pressing all-ceramic restorations became a reality in 1991 when we introduced a pioneering new method of fabricating dental restorations: the ceramic pressing technology.

Pressing pays off

As minimally invasive as possible

Our press technology is state of the art. The straightforward fabrication process delivers on its promises. The components of the system are fully coordinated and produce highprecision restorations[3]. You will benefit from enhanced productivity, lower investment costs and the added value stays in your dental laboratory. Highly economical and efficient: several restorations can be produced in one press process.

The objective of modern dentistry is to maintain the tooth structure to the best possible extent.

IPS e.max® Press exhibits high flexural strength (470 MPa) [1] and toughness [6]. Consequently, it can be used to press very thin restorations. Due to its excellent marginal quality and accuracy of fit, the material is suitable for fabricating veneers of 0.3 mm thickness as well as full-contour crowns of only 1 mm thickness [3].

Trust builds confidence: our 10-year IPS e.max® guarantee

We offer impressive aesthetics

15 years, 150 million restorations [4], 96% survival rate [5]. The 10-year IPS e.max® guarantee is as impressive as IPS e.max® Press is in and of itself.

The IPS e.max® Press lithium disilicate glass-ceramic (LS2) enables you to produce natural-looking masterpieces of utmost precision[3]. IPS e.max® Press brings out the best in dental laboratory technology: customised fabrication of aesthetic restorations on the basis of skilled craftsmanship and aesthetic sensitivity – with the aim of enhancing the quality of life and wellbeing of your patients.

(Crowns (13 – 23) IPS e.max Press, IPS e.max Ceram Dr Michele Khabbas / Hilal Kuday, Turkey)

The press technology, that inspires Dental technicians and dentists can fully trust our original pressing technology [7]. It fits into every workflow and budget without having to make any compromises. The workflow combines reliable all ceramics materials [1] such as IPS e.max® Press, and future-oriented equipment such as Programat press furnaces.

Is your denture clinic on dentist.com.au?

I

hope that everyone is looking after themselves, physically and mentally, as we continue to endure this particularly stressful and challenging

By Joseph Allbeury period. If you think it sucks, you’re 100% right; if you think it will never end, then I can assure you it definitely will and maybe you should talk that through with a friend, colleague or a counselling service if you’re stressed. Better days are ahead... it is just a matter of when. And when will not be too far away now.

With New South Wales locked down until at least the end of September, we have been forced to move the Digital Dentistry and Dental Technology event to June 3-4, 2022, again at the Novotel Sydney Brighton Beach. The need to move this event is always preceded with tremendous anxiety for me; so much work is involved in organising large scale events and there are so many people involved, it is a very emotional exercise to have to unravel it. We remain committed to staging a fantastic face-to-face event and we hope that with the prospect of overseas travel opening up next year, that we can even welcome some international speakers onto the program. Thank you to everyone who remains registered for the event, thank you to all our amazing speakers and thank you to all of our sponsors and industry partners who are instrumental in the success of the event.

On a more positive note, the investments we continue to make in projects on the internet are being used by the dental profession more and more. The video streaming service we launched a year ago at www.dentevents.tv is continually being expanded with more content and dental professionals are enjoying watching the variety of material available free and on-demand. Our goal for this site has always been to allow the dental profession to share their own videos easily and we have now launched a facility where you can upload your own videos for streaming on Dentevents.TV. Any videos related to dentistry - from humour and opinion, to product reviews, marketing and practice management info to clinical and technical videos - are welcome. Anyone can now login and load their videos with ease. See page 16 for more information.

Our find-a-dentist websites at www.dentist.com.au and www.dentist.co.nz are also enjoying increased visitor numbers from the public looking for dental practices and denture clinics, so please search for yourself on the websites and if your details are missing or incorrect, please go to the new form at dentist.com.au/information-for-dentists and let us know all the correct details.

We also have a new Express Listing facility for events on the Dentevents.com calendar (see page 16). If you’re organising webinars or face-to-face events, you can now submit the information for publishing on the calendar in a minute or two and immediately increase awareness of your event.

I’m looking forward to seeing the last of these lockdowns and getting back to normal (version 2022). Stay safe!

The press technique turns 30 and the aesthetic dentistry success story continues

I

n 1991, Ivoclar Vivadent came up with a completely new way of fabricating dental restorations. As one of the worldwide leading manufacturers of integrated solutions for high-quality dental applications, the dental company from Liechtenstein had the pioneering idea of pressing allceramic materials and subsequently developed the press technique. This process is regarded as a milestone in aesthetic dentistry and as a proven and future-proof manufacturing method.

Every four seconds, somewhere in the world, a restoration made with Ivoclar Vivadent pressed ceramics is placed.

Despite the arrival of other new fabrication methods, dentists and dental technicians continue to trust this unique and reliable process - using it with enduring enthusiasm and utmost conviction. The press technique continues to be state-of-the-art.

Gold alloys used to be the go-to material for dentists and dental technicians who wished to minimise the risk of intolerance in patients. However, these materials showed shortcomings with regard to their aesthetic appearance and wear behaviour and they could not fulfill the growing demand for metal-free solutions. In response to the needs and requirements of the industry, Ivoclar Vivadent came up with the visionary idea of pressing allceramic restorations and established an entirely new development approach.

Amazing all-ceramics he hot-pressing technique, which was originally used to press the IPS Empress ceramics, together with the Programat press furnace, steadily evolved into a true alternative to casting dental alloys.

All-ceramic restorations were shown to offer a wide range of benefits: compatibility with the natural tooth structure; neutrality in relation to other materials; light transmission properties similar to those of dental enamel; and a tooth-like appearance – in large part due to the nearly “invisible” restoration margin. A passion

for producing highly aesthetic restorations and the satisfaction derived from fulfilling the corporate mission of “making people smile” spurred the company on over the years to consistently refine the technique in terms of aesthetics, function and strength.

manufacturing. The system helps to cut down on time-consuming steps and consequently maximises the efficiency of the fabrication process. Nevertheless, exceptional technical skill and a well-trained eye are still the most important assets of the dental technician for imparting restorations with a uniqueness all of their own. Overall, however, the efficiency of the dental laboratory increases due to the fact that several wax-ups can be fabricated in one printing process. The laboratory not only benefits from its enhanced productivity, but also from the added value it creates. Therefore, the ceramic pressing technique is considered to be a proven and at the same time future-proof manufacturing method.

Lab-proven and future-proof he 30-year success story of the press technique provides a good reason to celebrate for Ivoclar Vivadent. An informative website has been created by the company that showcases in detail all the features and benefits of this fabrication method. In addition, all registered visitors to the page take part in a competition in which a number of attractive prizes can be won. The main prize is a smart, state-ofthe-art Programat EP 5010 G2 press and ceramic furnace. It is worth taking part.

T A new milestone: IPS e.max n 2005, Ivoclar Vivadent introduced another breakthrough material: the lithium disilicate glass-ceramic IPS e.max.

Armin Ospelt, Senior Director of the Global Business Unit Labside Analog, had the following to say about the pioneering press ingot: “IPS e.max Press has confirmed its longevity in everyday clinical practice. One hundred million restorations and a survival rate of 96.2% bear testimony to its success. The IPS e.max guarantee is as promising as the material itself”.

New M2 milling unit comfort line Fully automatic, flexible, open and with the extra-large Teleskoper Orbit ø 125 mm: 1 orbit for 4 different blank diameters!

T

he new M2 milling unit comfort line stands for modern operating comfort and flexibility. With the M2 Wet Heavy Metal, the M2 Teleskoper, the M2 Dual Wet Heavy Metal, the M2 Dual Teleskoper and the M2 Dual Double Teleskoper, the comfort line comprises five milling units with fully automatic 5+1 axis simultaneous milling technology. The highlight in terms of flexibility is the extra-large Teleskoper Orbit (ø 125 mm) that, in combination with special interchangeable holders, permits to process all common soft and hard material blanks of ø 95 mm, ø 98 mm, ø 106 mm or even ø 125 mm. With the Teleskoper Orbit blanks can be removed and reinserted back into the orbit at the same position with a precision in μm range. This is particularly helpful for adjusting the friction of telescopic jobs or for the two-stage fabrication of immediate restorations in case of implantsupported prostheses (with the Double Milling technique). All M2 milling units are stand-alone solutions: it is possible to start milling and calibration processes or load elaboration tools directly from the machine via the integrated PC with touchscreen. The optical tool detection ensures greater safety during milling. The two separate large milling chambers are the trademark of the M2 Dual milling units. However, also the M2 and the M2 Teleskoper milling units are characterised by spaciously designed, optimally illuminated and easily accessible milling chambers as well as with a separated, contamination-protected tool chamber with 21-compartment automatic tool changer (optionally, up to 84 for the M2 versions). The automatic self-cleaning function, the integrated Cleaning Kit for an easy cleaning of the milling chambers and the Ioniser (optional) ensure a particularly clean elaboration of the materials. The performance range of the machines can be extended by integrating different accessories available, e.g. the Glass Ceramic/Raw-Abutment® Holder and the JawPositioner Support. With the M2/M2 Dual Upgrade Kit, the M2 Wet Heavy Metal and the M2 Dual Wet Heavy Metal milling units can be upgraded to the Teleskoper version.

Press ceramic, rediscovered!

Dental technician Ömer Gençtürk, Antalya, Turkey

E

veryone is talking about CAD/CAM, which is playing an ever greater role in the fabrication of dental restorations. However, analog press ceramics are still used in many laboratories.

It is still an established, economical and efficient fabrication method. Until now, a reaction layer with the investment material could lead to surface imperfections and fit issues and has been a challenge. The lithium disilicate that is used often appears grayish and lifeless, due to its crystalline structure. That is not something that practitioners have to settle for, according to dental technician Ömer Gençtürk (owner of Da Vinci Dental Studio, Antalya, Turkey). He was given the new generation of press ceramic, VITA AMBRIA, made of zirconia-reinforced lithium disilicate for testing, in collaboration with dentist Dr Ahmet Emre Gülerik (DentGroup Clinic, Antalya, Turkey). He achieved a highly aesthetic result from the very first application. In the following interview, he describes his experience in

combination with the veneering ceramic VITA LUMEX AC on a cosmetic veneer restoration on four incisors in the upper jaw of a young patient.

Many dental technicians are reluctant to implement new materials in their laboratory. What was your experience here with VITA AMBRIA press ceramic? es, of course there are always concerns, especially if processes have generally been working well in the past.

In the end, curiosity prevailed. I wanted to see for myself whether I could really achieve better results by using the VITA AMBRIA material system. I simply followed the instructions for use. There was no learning curve. During my very first use, I could clearly see that VITA AMBRIA really delivers what it promises. So there is no need for concern when shifting to this new product.

Dental 3D printing: Is it accurate and precise?

By Terry Whitty

L

ooking at the world today, it’s easy to see why dental technology is a swamped with 3D printer choice. Let’s face it, a lot of sales companies, dental practices and dental laboratories see it as the “next bing thing”, even though its been accessible for the last decade.

Yes, machines have come down in price just go to ebay™ and you’ll find printers for five hundred dollars that will print nice trinkets and toys or the odd knob you were missing from a vintage stereo system. But is it suitable for dental applications? From a multitude of experience, the answer is a resound no! Now I know some of you will argue that you have a cheap 3D printer and it works great for the things you need it to do... and sure, you may get a dental model out of it that looks ok... but is it accurate and possibly even more importantly, can the results be repeated time and again with confidence?

To answer these questions, we need to delve into the properties that matter when choosing a 3D printer suitable for dental applications. However, before we do this, let’s recap on the technology known as Stereolithography that is behind most light-cured resin printers released of late. The word “stereolithography” is a portmanteau of “stereo”, meaning solid and “photolithography” which is a form of “writing” with light. Stereolithography with your 3D printer does exactly that: drawing solids with light one layer at a time.

Figure 1. Basic SLA printer showing Build platform resin tank and printed part.

There are three main categories of SLA processes are laserbased stereolithography (laser SLA); digital light processing stereolithography (DLP-SLA); and masked SLA (MSLA).

For all these processes, a vat of photo-reactive liquid resin is selectively exposed to light in order to form very thin solid layers that combine to create one solid object. Even though laser-based SLA, DLP-SLA, and MSLA are all types of stereolithography and utilise similar technology, they can produce significantly different results even when printing the same object.

Tips for pouring or injection for cold cure acrylic with putty silicone

By Angelo Di Franco, MDT

Figure 1. Air trapped during an inefficient packing or pouring technique can lead to issues.

Figure 2. Pouring acrylic using a silicone key.

Figure 3. Clean denture with no residue from plaster.

s many will know, dentures are traditionally made with stock acrylic denture teeth placed in a wax base, invested in gypsum, boiled out and packed in the acrylic using the “pack and press system”. It’s a good, tried and tested “lost wax” system but one that can be fraught with issues unless attention to detail is observed.

Even though the basic “lost wax” system can still be used, there are alternative ways to manufacture the denture base material. Firstly, lets look at an alternative to standard acrylic teeth.

High molecular weight resin H.M.W. (PMMA Cross-Linked) teeth are a good alternative to standard acrylic denture teeth. The use of high molecular weight modified polymers combined with special molecular linkers (Cross Linking) results in advantages including exceptional hardness, excellent abrasion resistance, colour stability and superior resistance to biofilm. Other features of ideal denture teeth include:

• Geometry of the teeth constructed according to Strack’s research for constructing bilateral balanced dentures where a Cusp angle of 20° is suggested.

• Aesthetic zone: If we do not receive any information of the face of the patient, refer to the shape of the upper alveolar crest, which can provide information as to the shape of the teeth to be used.

• Fluorescence is a natural form of luminescence that is found in certain substances. It is a feature that is found in natural teeth which, when struck by certain light wavelengths, primarily UV light, give off a white-bluish light. This feature is found in some manufactured teeth to give them an even more natural look. You will look great at the disco with these teeth in your mouth!

Thanks to scientific research and the results obtained with nano-technologies, it has finally been possible to influence and change the polymer-monomer ratio.

With the introduction of a new molecule in the polymer loaded with micro-pearls of composite, the advantages compared to traditional resins are significant.

The prostheses turn out to be very compact and strong, easily polished and extremely precise. The range offers the possibility of customised characterisation with stains achieving excellent aesthetic results.

Advantages include low monomer residue, excellent consistency and dimensional stability, high polishabilty thanks to the micro-pearls in a dentine colour, higher fluidity during the injection, low adhesion of plaque, higher adherence to denture base, low shrinkage, very low specific weight and colour stable for many years.

Now to the base material. Micropearl denture base acrylic is a great acrylic and can be used for multiple purposes such as relines, additions, repairs and partial dentures, as well as chrome and All-On4™frameworks, reducing material costs and storage space. It is a cold-curing resin for the injection, pouring or pressing techniques.

Different colours are available but the same stability and no shrinkage to meet all your needs: full and partial dentures, repairs and relining could be performed in an easy and fast way resulting in a top aesthetic prosthesis with less residual monomer.

Dear Technicians and Prosthetists, Here are 2 excellent ideas for improving clinical outcomes and helping your dentists with two great products we have developed at Piksters-Erskine Oral Care … Gorilla Floss and Right Angle Piksters.

We are giving these away to you FREE – one of each item for each crown or bridge you send to your customers.

Here’s something novel – Floss that won’t break when checking tight contacts! We invented Gorilla Floss as the worlds strongest floss – see right for the amazing outcome.

150m

Gorilla Floss & Implant Floss are 4 times stronger* than other leading brands

Our Sydney laboratory testing shows that it is four times stronger than most floss. An American lab said it was 2 to 3 times. I’m not arguing – it’s incredibly strong and you’ll be amazed.

Data taken from ‘Tensile Testing Machine’ used to measure the breaking force.

*

Gorilla Floss Brand 3 Dentists and patients absolutely hate it when the Brand 1 Brand 4 floss snaps in their mouth and their fingers go Brand 2 Brand 5 flying off into the cheek or the palate. It is quite shocking to the patient and people get really annoyed. I know, I was a clinical dentist for 30 years in Sydney and experienced a lot of problems that inspired me to make some solutions. Dentistry is a tough gig. It’s nice to be able to help people to not go through the problems and pain that I did, and floss that repeatedly snaps in the mouth was a major ‘pain’. You can now kiss goodbye to that problem and still have a tight contact if you use Gorilla Floss.

It’s still very unknown and undiscovered.

I’d like to give you enough of this floss free so that you can put one in with every crown you send out...

Your dentists will love it.

Just ring up and say “I’m a technician and I would like 30 or 40 free Baby Gorilla Floss to give to my dentists with every crown I send them in the next few months.”

Your dentists will thank you for the recommendation and sample.

As we know, it is better if the dentist can leave the extra tight contact to self adjust/disperse and just know that it feels okay to floss and is not too tight – but better tight than a food trap! Tight goes away, traps don’t!

Gorilla Floss enables the dentist to keep a good extra tight contact and not have to mess around trimming and polishing porcelain contact points.

For your bridges…

Also your dentists receiving your bridge will be very happy to get a free packet of our new Right Angle Bamboo Piksters®.

We are going to offer you one free packet for every bridge you send out for the next few months – just ring and tell us how many bridges you are going to send out and we will give you one free variety pack to give away with each bridge.

Patients love this brush because they don’t have to bend the wire, they don’t have to get their hand in their mouth & it is so much easier to clean underneath the bridge than using floss threaders. My former dental hygienist said “make sure you tell everybody about these – they are the best thing that ever happened to bridges … so easy to clean under”.

Of course Piksters® were always pretty popular but this new long handle with the pre-set 90° makes it even better.* Finally if you haven’t tried our Piksters® Mini Oral Appliance Cleaning Kits – they are very effective & super cheap and very well received – a brilliant way to clean and deodorise all removables. We can’t afford to give everything away – but if you want to sample these to your dentist with each removable, please call 1800 817 155 and we will give them to you at cost ($2.28 and this is given to you on trust on the basis that you use it only for sampling to the dentist who you think may benefit from such a kit) – with the hope that your clients will value their association with you as a technician who value ads, and sends them highly effective and useful products that helps wow the patient and grow their dental practice. Could be a win-win.

I hope you like it. Please feel free to ring me or my staff to give any feedback.

Dr Erskine-Smith, BDS FPFA CEO, Piksters®-Erskine Dental

Offers expire 1st December 2021. *The long bamboo handle works really well – it gives a precision feel and you’re not using big thick plastic handles to get the same degree of stiffness and responsiveness.

prosthetic | TECHNIQUES

Some tips of use follow: 1. First layer of addition silicone A+ B 60 shore should be placed under pressure at 4-5 atmosphere, minimum 5 minutes, for excellent definition of detail (clean your hands with soap before mixing it to avoid alteration of the silicone). Then cover all of it by addition Putty 70/80 shore.

2. Use the measuring spoons.

3. After the setting time, open the flask and remove the waxed up denture (no need for boil out). Check inside of the mould for loose particles and clean carefully. Teeth should be steamed cleaned and sandblasted (110-140 micron) around the edges and the base. Then re-steamed and dried, before replacing the teeth into the mould. This technique eliminates the need for drilling retentive holes at the base of teeth, which would only trap air.

4. Use Acrylic Bonder on the surface of the sandblasted teeth to increase the chemical bonding to base.

5. Accurately clean the model of wax or grease, soak the model in hot water (40 degrees) for 5-6 minutes, then isolate with separator fluid. Naturally, respect the mixing ratio of the acrylic polymer/monomer 2:1. Strictly follow the factory instructions. Do not mix the acrylic in a rubber container (Rubber absorbs part of the monomer) - use plastic or glass only. First liquid, then powder.

6. To avoid air bubbles near the sprues after pouring, place the flask in cold water at 2-2.5 bar pressure for 5 min, then increase temperature to 45 degrees and hold for 15-25 minutes (or per manufacturer’s instructions) . Do not cover the pouring sprues with water.

Cooling after curing approximately 5-10 minutes.

7. After polishing, immerse the denture in the water to release the residual monomer before delivery.

By following the above procedures, we reduce the shrinkage and porosity and maintain the features and specifications of the manufacturer.

Conclusion ome advantages of the pouring technique or injection for cold cure acrylic with putty silicone include saving time - only 45 minutes instead of 2-3 hours.

Very clean after devesting thanks to the addition silicone. No plaster “sticking” to the baseplate or teeth. Improved accuracy of vertical dimension.

Press ceramic, rediscovered!

Dental technician Ömer Gençtürk, Antalya, Turkey

E

veryone is talking about CAD/CAM, which is playing an ever greater role in the fabrication of dental restorations. However, analog press ceramics are still used in many laboratories.

It is still an established, economical and efficient fabrication method. Until now, a reaction layer with the investment material could lead to surface imperfections and fit issues and has been a challenge. The lithium disilicate that is used often appears grayish and lifeless, due to its crystalline structure. That is not something that practitioners have to settle for, according to dental technician Ömer Gençtürk (owner of Da Vinci Dental Studio, Antalya, Turkey). He was given the new generation of press ceramic, VITA AMBRIA, made of zirconia-reinforced lithium disilicate for testing, in collaboration with dentist Dr Ahmet Emre Gülerik (DentGroup Clinic, Antalya, Turkey). He achieved a highly aesthetic result from the very first application. In the following interview, he describes his experience in

combination with the veneering ceramic VITA LUMEX AC on a cosmetic veneer restoration on four incisors in the upper jaw of a young patient.

Many dental technicians are reluctant to implement new materials in their laboratory. What was your experience here with VITA AMBRIA press ceramic? es, of course there are always concerns, especially if processes have generally been working well in the past.

In the end, curiosity prevailed. I wanted to see for myself whether I could really achieve better results by using the VITA AMBRIA material system. I simply followed the instructions for use. There was no learning curve. During my very first use, I could clearly see that VITA AMBRIA really delivers what it promises. So there is no need for concern when shifting to this new product.

When working together with the dental practice, how important is absolute shade accuracy of the material to the VITA shade standards? he VITA shade guides are standard worldwide. Of course, the material also has to be precisely matched to the corresponding shade tabs. If I determine an A3.5 on the patient, there should also be an A3.5 in the press and veneering ceramic. This is the only way I can truly reproduce it in a way that is appropriate for the patient and also have the certainty that my customers and their patients are satisfied with my work. VITA AMBRIA, as the shading element, proved to be true to the shade in this patient case.

Removing the mould is always a tense moment. What was your experience with this process? es, that’s true. Removing the mould is really the moment of truth. Especially because I had never worked with VITA AMBRIA before. And, of course, it is also the moment when you hope that the ceramic will come out of the investment material without any damage. The thin veneers in this case study proved to be robust during the removal process. Another thing I noticed right away was the minimal reaction layer with the investment material and the flawless ceramic surfaces at the right furnace temperature. The restorations came out perfectly.

That’s why I didn’t have to do much more on the anatomically reduced surfaces to get deep results that appeared three-dimensional. For the shade gradient, I layered some OPAQUE DENTINE A1 cervically so it would be less chromatic after the incisal DENTINE A1. I created the mamelon anatomy effect using MAMELON saffron and highlighted it with intermediate layers of a one-to-one mixture of DENTINE A1 and ENAMEL clear.

How exactly did you proceed with the enamel layering using VITA LUMEX AC? What is your advice for creating a halo effect in the process? followed with alternating layers of translucent ENAMEL light, neutral ENAMEL clear, light blue OPAL TRANSLUCENT opal-azure and light yellow TRANSLUCENT light-blonde to establish a natural play of colour and light. After the first firing, the incisal final layering was then carried out with light blue TRANSLUCENT waterdrop. I was able to achieve a halo effect from the palatal plate using a balanced mixture of OPAQUE DENTINE A1, ENAMEL light and highly fluorescent FLUO INTENSE cream.

Dental 3D printing: Is it accurate and precise?

By Terry Whitty

L

ooking at the world today, it’s easy to see why dental technology is a swamped with 3D printer choice. Let’s face it, a lot of sales companies, dental practices and dental laboratories see it as the “next bing thing”, even though its been accessible for the last decade.

Yes, machines have come down in price just go to ebay™ and you’ll find printers for five hundred dollars that will print nice trinkets and toys or the odd knob you were missing from a vintage stereo system. But is it suitable for dental applications? From a multitude of experience, the answer is a resound no! Now I know some of you will argue that you have a cheap 3D printer and it works great for the things you need it to do... and sure, you may get a dental model out of it that looks ok... but is it accurate and possibly even more importantly, can the results be repeated time and again with confidence?

To answer these questions, we need to delve into the properties that matter when choosing a 3D printer suitable for dental applications. However, before we do this, let’s recap on the technology known as Stereolithography that is behind most light-cured resin printers released of late. The word “stereolithography” is a portmanteau of “stereo”, meaning solid and “photolithography” which is a form of “writing” with light. Stereolithography with your 3D printer does exactly that: drawing solids with light one layer at a time.

34 eLABORATE

Figure 1. Basic SLA printer showing Build platform resin tank and printed part.

There are three main categories of SLA processes are laserbased stereolithography (laser SLA); digital light processing stereolithography (DLP-SLA); and masked SLA (MSLA).

For all these processes, a vat of photo-reactive liquid resin is selectively exposed to light in order to form very thin solid layers that combine to create one solid object. Even though laser-based SLA, DLP-SLA, and MSLA are all types of stereolithography and utilise similar technology, they can produce significantly different results even when printing the same object.

Figure 10. Precision versus accuracy. If I’m shooting at a target and my goal is to hit the bullseye all the time, the four possible states.

Laser-based SLA was the original means of stereolithography that was developed in 1986. The technology works by using a UV laser to draw each layer of the object and uses mirrors driven by a motor, known as galvanometers, one on the X-axis and one on the Y-axis, to rapidly aim the laser beam across the print area, solidifying resin as it moves along. In order to create a solid object, the design must be broken down, layer by layer, into a series of points and lines that the laser traces out. Formlabs™ is an example of a printer that uses this technology.

DLP-SLA uses a digital projector to expose a single image of each layer across the entire resin vat at once. Because the image of each layer is digitally displayed, it is composed of numerous pixels, resulting in a layer formed from small rectangular bricks called voxels (three-dimensional pixels) that combine along the Z axis to create a solid. Asiga 3D printers use this technology.

MSLA utilises a light source made up from an array of UV LED’s and combined with an LCD screen used as a “mask “ in order to shape the light image from the LED array. Like DLP, the LCD creates a shape composed of pixels that is displayed.

The pixel size varies based on the resolution of the LCD screen and hence individual pixels are deactivated on the LCD to allow the LED light to pass through to form the resulting shape for the layer and ultimately the solid printed object. An example of this technology is the Ackuretta SOL Printer.

In terms of accuracy and precision and the factors that affect this in 3D printing, resolution is a good place to start.

Often in the specifications of a printer you will see XY resolution and of course you will expect that a lower number will be better. To a point this is true. However, with 3D printing, there are

36 eLABORATE

Figure 9. Measuring a printed model against the original in colour mapping metrics software.

Figure 11. X and Y are planar axes and the Z axis is perpendicular to these. 3D printer specs refer to the resolution of XY axes and the Z axis correlates to the printer’s layer thickness. actually three dimensions to consider: the two planar 2D dimensions X and Y and also the Z dimension that makes it 3D printing (See Figure 11). Since the planar and Z dimensions are generally controlled via very different mechanisms, their resolutions are going to be different and need to be treated separately. As a result, there is a lot of confusion about what the term “3D printing resolution” means and what level of print quality to expect.

For XY resolution, as a generalisation, you could say that the lower the pixel size or laser spot size, the higher the resolution. For example, your 4K television has a higher resolution than your HD TV because the pixel size is smaller and there is more of them for the same area so it follows that a smaller laser spot, or higher definition projector or LCD screen will give better resolution. It does not really matter if your pixel or spot size is 47 µm vs 49 µm but it will matter if the size is 50 micron vs 100 micron. It’s a bit more complex than this but suffice to say for this article, the concept is valid.

For the Z axis resolution, this is often known as “layer thickness” and you will always see this in the settings of your printer software as this will be the thickness of each slice to be printed.

Often this correlates to how “smooth” the resultant print appears to be and the lower the number means the thinner the layer of material being cured per layer ao that the “stepping” effect is reduced. Conversely, printing time will be longer. Whilst not exactly double, the time to print an object in 50 micron layers rather than 100 micron layers, is pretty close to it so if time is a consideration, try a larger slice thickness and compare. On most printers, anything beyond 50 microns is probably not worth the wait in my opinion as the result is about as good as you need for most dental applications and often hard to discern.

Just because you have a “high resolution printer” does not mean you will have good or accurate prints. You must have quality components and a decent build quality and all this of course does not come cheap. A lot of printer companies advertise amazing resolutions - HD, 4K, 8K - but this means nothing if the rest of the components are not of high quality and the build quality is less than optimal. One of the main areas often overlooked is the quality of the light source. In most printers, the light power of the light source changes over time - the higher the quality of the printer components, the longer you can expect the lifespan of your light source to be. A light source that does not send equally bright light over time through to the resin tank will inevitably cause failed prints. The best light sources are the once that have sensors and electronic circuits that will adjust the light source to optimal for every print, again you don’t get this in cheap printers.

You can measure how accurate the print is by scanning a test piece, say a dental model and then setting up the printer to print this test piece. Once printed, you can scan the 3D printed model and compare it with the original in a metrics software program. A colour map will show the comparison of the original model and the printed model and any discrepancies between the two.

Some of the factors that will effect this accuracy include: • Environment: If your room is too bright, it may prematurely cure the resin if accidentally exposed. The ambient temperature also may effect print accuracy.

• Resin quality: You cannot take this one for granted. The reality is a cheap resin is usually cheap for a reason. It may look OK when printed, but give it 24 hours and it could be unstable, shrink or lose mechanical properties. There is a big difference in the quality of resins available, especially for “open” printers. You will usually get what you pay for. Resins shrink, so when the shrinkage factor is known, this can be dialled into the software and accounted for. If it’s not known, you will get an inaccurate print.

• Slicing software: Setting up your design in software is the final step before starting your printing process. Misprints due to poorly planned setups are common. There are three main forces at play - suction, peeling/separation force and gravity which have an impact on how you should plan printing. Good design can limit or even remove these forces, safeguarding the accuracy of your print. For example, if you print a surgical

38 eLABORATE

Material

guide vertically, the peeling/separation force might cause your holes for the drill tubes to be slightly oval, whereas printing it parallel to the build platform will result in the holes being more accurate and round.

• Post processing: This is a big one. This process requires pre-set parameters and careful execution. A 3D print that’s not cured correctly will continue its curing process in an uncontrolled manner when exposed to natural UV light. This will cause inaccurate results over time and you will not be happy with the results.

So what is precision? At a first look, you would think accuracy and precision are the same thing, but they are not. Have a look at Figure 10 and you’ll see that if I was shooting at a target, the 4 states of the relationship of precision and accuracy. They are very different things indeed. Precision actually equates to repeatability and a real world example of this in 3D printing is the ability for the Z axis mechanism, usually a worm drive, to be able to return to its zero position consistently.

Interestingly, just as with most technical specifications for 3D printing, precision is not just determined by the 3D printer. Other factors, such as the choice of resin, has an impact on the precision of your outcomes as well. Opting for high-precision/high-quality resins will most likely result in better outcomes. This is mostly due to the quality control mechanisms that premium resin manufacturers apply to all their products and in the case of resins, they especially need to focus on batch consistency.

For accuracy and repeatability in 3D printing, there are many factors to consider encompassing hardware, software, material and environmental, as well as the wildcard of the human factor that will have an overarching affect on the entire process.

thermoforming | TECHNIQUES

The 7 minute 40 second aligner

By Peter Herring, Adv Dip Dent Tech, ACCDP

W

e find ourselves producing more and more thermoformed aligners and retainers these days, therefore it’s important to be able to produce these quickly and consistently.

Clear aligner systems in particular call for a large series of aligners and with the low profile printed models typical used in these treatments, removal of the thermoformed foil from these abbreviated models is often a sticking point in the process.

Here we offer a suggestion to ease this.

An integral component that speeds pro-

duction is the automatic thermoforming unit; if you have to wait and manually perform the thermoforming operation, the production time will be increased by up to 50%. The material used here is Erkodur-al and the total hands on production time from bare model to finish is just 7 minutes and 36 seconds.

When working with a full model, it’s best to embed to just below the intended finished extension of the appliance. This facilitates easier removal, optimises the material thickness and as a bonus, the angle created at the junction of the model and granules is a handy guide for trimming.

Smaller, usually 3D printed, models are formed directly on the plate. A small amount of time spent creating areas of relief around the base to accommodate instruments will pay dividends, making it much easier to remove the foil after thermoforming. Here we have blocked out 5 areas around the arch with Erkogum (reusable - Prod #110844).

To remove the foil, use the Take-off pliers (Prod #110880). These pliers work in a reverse action - the jaws open when the handles are closed, lifting the thermoforming from the model. Work around the model easing the foil upwards at each point until it is free. This will minimise damage to the foil and the model but with gypsum models, breakage is always a possibility.

Now, using curved scissors, trim the foil as closely as possible to the extensions of the finished aligner or retainer but without spending too much time; the borders will be refined in the next step. Designed for thin materials, the Special Scissors XL (Prod #220301) have extended handles for increased leverage and to keep the hands away from the cut edges of the foil.

thermoforming | TECHNIQUES For final shaping and gross reduction we like the Blue Grinding Stones from Ray Purt Dental. The larger diameter make it quick to define and shape the peripheries to the desired extension and contours while leaving a fairly clean cut. Operate at around 12,000 rpm to minimise heat build up. For this stage we are only concerned with creating the finished dimensions; smoothing and finishing is the next step.

Lastly, we take the double Lisko discs (Prod #223100) and move around the peripheries at low speed (<10,000 rpm) to smooth the edges and dislodge any grinding burs.

When this step is finished, peel out the inbuilt isolating foil to reveal the crystal clear finished appliance.
