Abstract

The purpose of this study was to investigate the effects of various retainer designs on the characteristics of stress distribution and vertical dislodgment of the denture base. A mandible simulation model of unilateral distal-extension missing teeth (three teeth from the second premolar to the second molar) was used in this study. A conical crown, Akers clasp, and double Akers clasp were used as retainers.<BR>The results were as follows:<BR>1. The conical crown retained denture produced significantly less stress distribution and vertical dislodgment of the denture base than the two clasp designs.<BR>2. The conical crown retained denture produced the most intense stress on the apical and distal surfaces of the most distal abutment, while the double Akers clasp design produced the least stress.<BR>3. The Akers clasp design produced less load distribution of the denture base and greater vertical stress of the abutment tooth than the double Akers clasp design.<BR>4. The bilateral denture design produced less load distribution of the denture base and greater vertical stress of the abutment tooth.<BR>5. On condition of the bilateral denture design including clasps with a proximal plate, stress and load distribution were similar to those of the conical crown retained denture.
