Question 1

What is a Removable Partial Denture?

Answer 1

Removable Partial Denture
A dental prosthesis that restores one or more but not all of the natural
teeth and/or associated parts and is supported by the teeth and/or mucosa
and can be removed from the mouth and replaced at will; often referred to
as an RPD

Question 2

What are the objectives of RPD?

Answer 2

 Restore anatomical defect
 Restore function
 Restore occlusal plane
 Provide posterior occlusal support
 Improve esthetics
 Splint periodontally compromised teeth

Question 3

What does the metal framework consist of?

Answer 3

Metal framework

• Major connector
• Minor connectors
• Rests
• Direct retainers
• Indirect retainers

Question 4

What does the denture base consist of?

Answer 4

Denture base
-Replacement teeth
-Supporting base
Material

Question 5

Denture base :

Answer 5

applies to where the teeth is missing

acrylic rests on edentulous area

Question 6

What is the role of the Major Connector?

Answer 6

MAJOR CONNECTOR
The component of an RPD that joins the units on one
side of the dental arch with the units on the opposite
side

Question 7

What consists of the Major Connector for the Maxillary part?

Answer 7

 Palatal strap
 Anterio-posterior Palatal Strap
 Complete Palate
 U-shaped (Horseshoe) connector

Question 8

What consists of the Major Connector for the Mandibular part?

Answer 8

Lingual bar

Lingual plate

Question 9

What is the role of the Minor Connector?

Answer 9

MINOR CONNECTOR

The connecting link between the major connector or base of a removable partial denture and the other units of the prosthesis, such as
direct and indirect retainers and rests.

Question 10

What are the different types of Minor Connector?

Answer 10

MINOR CONNECTOR
-Types -
 Guiding plane plates
 Meshwork – to hold acrylic resin
 Any unit connecting any type of rest to the
major connector

Question 11

Describe an example of how a Major Connector works:

Answer 11

Major connector should be connected to the occlusal rest,

Major connector connects to the retainer via the minor connector

Question 12

What is referred to as Rest?

Answer 12

REST: A component of a removable partial
denture that serves to transfer forces
occurring against the prosthesis down
the long axis of the abutment teeth

Transfers to the partial denture

Question 13

What is the Rest Seat?

Answer 13

REST SEAT: The prepared surface of a tooth or

restoration to receive the rest, not a part of framework

Question 14

What is the Proximal Plate?

Answer 14

 A rigid extension from the major connector
or base
 Contacts the proximal surface of an
abutment tooth

The vertical portion of the retention plate~

Question 15

What are Direct Retainers?

Answer 15

A component of a removable partial denture used to retain and prevent dislodgement

should not affect tissue or apply extra forces on the abutment teeth

Question 16

Describe the Clasp Assembly:

Answer 16

Clasp Assembly
Two arms or other pieces, joined by a body
which may connect a rest
May act as a retainer or stabilizer

Question 17

What are Indirect Retainers?

Answer 17

INDIRECT RETAINERS
A component of a removable partial denture that assists a direct retainer(s) in preventing displacement of a distal extension denture base by functioning through lever action on the opposite
side of the fulcrum line

Question 18

What do Indirect Retainers usually connect to?

Answer 18

 Usually connects to a major connector and is

some form of rest

Question 19

Indirect Retainers :

Answer 19

 ALWAYS necessary in Class I or II situations

Question 20

What is the Denture Base?

Answer 20

Denture Base
 Part of the RPD that rests on the foundation
tissues and to which teeth are attached.
– Polymer/Plastic or Metal

Question 21

What is Acrylic Resin Attachment?

Answer 21

ACRYLIC RESIN ATTACHMENT
The part of a RPD which rests on the
oral mucosa and to which the teeth
are attached

Question 22

What is the function of Acrylic Resin Attachment?

Answer 22

Function: Transmits stress to the supporting structures

Question 23

Proximal Plate is also known as

Answer 23

Guiding Plate

Question 24

Denture Base Retention is…

Answer 24

Part of the framework to which the resin base is attached
