PPT-Support for the Distal Extension Denture Base

Rola M Shadid BDS MSC Factors Influencing Support of the Distal Extension Base 1 Contour and quality of the residual ridge 2 Extent of residual ridge coverage by the denture base 3 Type and accuracy of the impression registration. By. HEAD OF DEPARTMENT. Dr. Rashid Hassan. Assistant professor. R.I.H.S. ISLAMABAD. 1. DENTURE BASE MATERIALS. Denture base materials can be divided into two types.. 1. METALLIC DENTURE BASE:. Gold alloys, cobalt chromium alloys.. Rola. M. . Shadid. , BDS, . MSc. The denture base supports the artificial teeth and consequently receives the functional forces from occlusion & transfers functional forces to supporting oral structures. (stress equalizers). In the distal extension RPD support is derived from both the residual ridge and abutment teeth. The variation in consistency providing this support allows some rotational movements of the free-end base towards the soft tissues. 1.
