Abstract
In making a complete denture, the selection of the artificial posterior teeth is one of the important factors to obtain denture stability and to avoid high pressure applied to the supporting structure under a denture. The purpose of this study was to investigate the influence of the occlusal surface of the artificial posterior teeth on the pressure distribution under a complete denture.The results were as follows:1. In centric occlusion, the occlusal surface of different artificial teeth did not affect the pressure distribution under the complete denture.2. In one-side occlusion, the pressure values were changed remarkably in the buccal area on the working side and palate area as compared with the pressure distribution under the complete denture with two different artificial teeth.3. In one-side occlusion at an eccentric position, the occlusal surfaces of the artificial teeth affect the pressure distribution under the complete denture. The pressure values under the lower denture with Bio-Ace artificial posterior teeth increased on the nonworking side.
