Tooth tissue supported RPD

The denture base that extends anteriorly/ posteriorly and is supported by teeth at one end and tissue on the other end – distal extension partial dentures.

They are used in patient where tissue changes are expected, where a permanent prosthesis cannot be fabricated till the tissues stabilize.

Interim denture

It is a temporary partial denture used for a short period to fulfill aesthetics, mastication or convenience until a more definite form of treatment can be rendered.
