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

23

When are pontics mostly used

Fixed partial dentures and bridgework
