The part of a removable partial denture that contacts a tooth it affords primarily vertical support is called.. Rest

The part of a removable partial denture that contacts a tooth it affords primarily vertical support is called:

• 1. Minor connecter.
• 2. Major connecter.
• 3. Rest.***
• 4. None.

The correct answer is: 3. Rest.

A rest is a small metal clasp that sits securely on the prepared surface of a remaining tooth on the opposite jaw. Its primary function is to provide vertical support for the removable partial denture, preventing it from sinking into the gum tissue and overburdening the remaining teeth.

Here's why the other options are incorrect:

- Minor connector:

Minor connectors join different parts of the denture framework like clasps and bars but don't directly contact teeth.

- Major connector:

Major connectors bridge larger gaps between remaining teeth and primarily stabilize the denture against horizontal movement.

- None:

All the above options except "None" play a role in supporting partial dentures, but only rests provide primarily vertical support.
