removable partial denture and the
other units of the prosthesis, such as
direct and indirect retainers and rests.

Question 9

MINOR CONNECTOR
-Types -
(3)

Answer 9

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

Question 10

REST:

Answer 10

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

Question 11

REST SEAT:

Answer 11

The prepared surface of a tooth or
restoration to receive the rest, not a part of framework

Question 12

RPD Components: Proximal Plate
(2)

Answer 12

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

Question 13

DIRECT RETAINERS

Answer 13

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

Question 14

DIRECT RETAINERS
Clasp Assembly
(2)

Answer 14

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

Question 15

INDIRECT RETAINERS
(2)

Answer 15

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 16

INDIRECT RETAINERS
 Usually connects to a

major connector and is
some form of rest
