1
How is acrylic used in RPDs
Acrylic resin denture base that holds the replacement teeth
2
What acrylic resin is used in RPDs
Thermoplastic acrylic resin - polymethacrylate
3
Describe how cobalt chrome is used in RPDs
Cast framework that holds the replacement teeth
Metal alloy of cobalt and chromium
4
What are the different Craddock classifications
Class I - tooth borne
Class II - mucosa borne
Class III - tooth and mucosa borne
5
Describe tooth borne support
Everything rests on the teeth
Saddle supported in both sides by substantial abutment teeth
6
Describe mucosa borne support
Everything rests on the mucosa
Biting forces resisted entirely by soft tissue
7
Describe tooth and mucosa borne support
Mixture - some of the denture rests on teeth, some rests on mucosa
Tooth supported at only one end of the saddle
8
Describe Kennedy classification 1
Bilateral free end saddles with natural teeth anterior to the edentulous space
9
Describe Kennedy classification 2
Unilateral free end saddle
10
Describe Kennedy classification 3
A single bounded saddle
11
Describe Kennedy classification 4
An anterior bounded saddle crossing the midline
12
What is a shortened dental arch
A dentition where most posterior teeth are missing
Must have at least 20 teeth
Can provide a stale and acceptable dentition
13
What are the components of an RPD
Coast
Rest
Major connector
Minor connector
Saddle
Abutment
Pontic
14
What is the purpose of a clasp
Engages a tooth and enters an undercut for retention
15
What are the different types of clasp
Occlusally approaching - molars
Gingival approaching - anterior teeth and premolars
16
What is a rest and what are the different types
Part of the framework that contacts a prepared surface of the tooth
Can be:
Occlusal
Cingulum
Incisal
17
What is a major connector
The portion that connects the components
18
What is a minor connector
The component that serves as the connecting link between major connector and other components such as the clasp assembly and occlusal rests
19
Describe a free end saddle
An edentulous space with an abutment tooth anterior and adjacent to it
20
Describe a bounded saddle
An edentulous space with abutment teeth anterior and adjacent, and posterior and adjacent to the space
21
What is an abutment
A tooth that serves to support a prosthesis
22
What is a pontic
An artificial tooth that replaced a natural tooth
Restores its function and usually restores the space previously occupied by the clinical crown
