1
Q

The amount of mechanical stimulus the tissue can withstand before it gets traumatized.

A

Physiologic Tolerance

2
Q

These RPD components resist horizontal movement.

A

Minor connectors and reciprocal clasps.

3
Q

Where do you want to transfer the forces on an abutment tooth?

A

As close to the center of the tooth and the horizontal axis of rotation.

4
Q

How far should the terminal 1/3 of the retentive clasp be from the gingival margin?

A

1.5-2 mm

5
Q

The axis of rotation of a tooth is located where?

A

Center of the root.

6
Q

This component of the partial:

  • Unifies all the parts of the framework.
  • Distributes the forces throughout the arch, to the selected teeth and tissue.
  • Minimizes the torque to individual teeth.
A

Major connector

7
Q

The major connector must have this quality in order to transfer forces throughout the mouth.

A

Rigidity

8
Q

This RPD component is rigid to provide cross-arch stability through the principle of broad distribution of stress, and covers no more tissue than is absolutely necessary.

A

Major connector

9
Q

This component of the RPD passes VERTICALLY from the major connector.

A

Minor connector

10
Q

Main goal of a rest.

A

Provide VERTICAL SUPPORT for the RPD.

11
Q

Provides AXIAL loading of the abutment teeth.

A

Rests

12
Q

6 things a clasp assembly MUST have:

A

1) Retention
2) Support
3) Stability
4) Reciprocation
5) Encirclement
6) Passivity

13
Q

Active components don’t put any force on the tooth when you insert the RPD. What is this called?

A

Passivity.

14
Q

Forms of indirect retention

A

Rests
Proximal Plates
Minor connectors

15
Q

The ______ the indirect retainer is from the fulcrum, the more ________ it should control movement.

A

farther; efficiently

16
Q

This should not be placed in an inclined surface.

A

Indirect retainer

Has to be on a VERTICAL surface.

17
Q

Acrylic needs this thickness in order to be strong.

A

2 mm

18
Q

Disadvantage of a metal base.

A

1) Cost
2) Esthetics
3) NO RELINING POSSIBLE!
4) Not appropriate when thickness is needed (due to cost and too heavy)
