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. SHOULD NOT EXCEED THE LEVEL OF PHYSIOLOGICAL TOLERANCE.

DR SHRADDHA RATHI, D/0 PROSTHODONTICS. INTRODUCTION. Denture insertion represents the elimination of a series of carefully considered and exacting procedures on the part of the dentist.. It represents also the movement eagerly awaited by the patient, who has co-operated both in time and efforts towards this event.. Arabella. . Yelland. Damage that may result from poor design.
