Reflection on Lower Partial Denture Design
I
n response to requests from members for a technical review on partial denture design, we have sourced two initial short video sequences. These videos are specifically aimed at training dentists and providing them with the background knowledge to enable them to determine, from their patient diagnosis, radiographs, and appropriate surveying, the path of Insertion of the prosthesis, and to note the available undercuts, then move on to designing the case on paper. As dental technologists, you will have come across a few individual clinicians who spend
much time and effort designing such prosthetic cases, whilst often you are left to design such for yourselves. In these video sequences the presenter indicates two different designs and the fundamentals behind these for Kennedy Class 1 cases restored by removable prosthetic restorations. You can therefore reflect on your thoughts for such partial cases and consider other potential designs that you might propose backed up with sound reasoning. ● Firstly, look at the following video: https://www.youtube.com/watch? v=aw1B9vh5wjU (5 minutes); in this
case, a design is developed for the bi-lateral free end saddle case. ● The next video looks at a Kennedy Class 1 Modification 1: https://www.youtube.com /watch?v=UADljD8QkPQ (7 minutes) where not only are there two free end saddles but there are also the 31 and 32 teeth missing. By reviewing these short videos, you should be able to confirm your understanding by answering the ten online CPD questions and claiming your members FREE CPD certificate.
CPD Questions Q1 Removable partial dentures designed for Kennedy class 1 are generally ...

Q3 If a lingual bar is the preferred option, what space is required between the lingual fraenum and the gingival margin of the teeth?
a) b) c) d)
a) Width of the occlusal surface and b) only b) The form of the supporting saddles c) Tooth support noted via radiographs and dental examination d) The tissues in general, and b) and c)
a) b) c) d)
Q4 What does the presenter describe the ‘RPI’ system for premolars as requiring?
Q5 What does the presenter indicate is the advantage of a metal Lingual Plate?

a) a) b) c)
a) b) c) d)
a) b) c) d)
Tooth borne dentures Tooth and mucosa borne dentures Mucosal borne dentures Bounded saddle support
Proximal plate Gingivally approaching ‘i’ bar. Three arm clasp and lingual bar Mesial rest and a) and b)

May 2017 | volume 4 | issue 3 CPD Questions (continued...) Q7 ‘xxxxxxxx’ is part of a removable partial denture framework that is made to counter
Q8 Utilising stainless steel wire what depth of undercut and diameter of wire is used in the video for clasps on the Kennedy Class 1, Modification 1 case design?
a) b) c) d)
a) b) c) d)
The effect created by another part of the framework’. Occlusal rest Lingual plate Reciprocation
.15 undercut with .75mm diameter wire .25 undercut with .9 mm diameter half round wire .25 undercut with .9mm diameter round wire .3 undercut with .75 diameter half round wire
Q9 How many edentulous saddles would you expect to see on a Kennedy Class 1 Modification 2 case?
Q10 The presenter indicates that the prognosis of a Kennedy Class 1 Modification 1 case may be less favourable ...
a) b) c) d)
a) Because of the long free-end saddles and few abutment teeth b) Due to clasps engaging less undercuts on lower premolars c) As the reciprocation is not as flexible as it is when it is a Kennedy class 1 simple case d) due to the further loss of a number of teeth caused by the denture movement

Dentists call for charges shake up Children and vulnerable patients risk losing out on access to free NHS dental treatment because of poor promotion and signposting of charge exemptions says the British Dental Association (BDA), as polling shows that just 74% of parents are aware that routine checkups are free for children aged under 18.
Following the latest 5% rise in NHS dental charges in England (from 1 April) dentist leaders have called on government to end the 'confusion by design' that's helping keep young and vulnerable patients away from their right to free NHS dentistry. ● Read more at: https://www.bda.org/ news-centre/press-releases/Pages/ Dentists-call-for-charges-shake-up.aspx
