Abstract

When making a complete denture, not only denture stability but also the restoration of function such as mastication and speech must be considered. The purpose of this study was to compare the pressure distribution in the supporting tissue under simulated upper and lower complete dentures using two different posterior occlusal schemes: fully balanced occlusion and lingualized occlusion.<BR>The results were as follows:<BR>1. In centric occlusion, the occlusal scheme of the artificial posterior teeth did not affect the pressure distribution under complete denture.<BR>2. In case of unilateral biting, the occlusal scheme affected the pressure distribution under complete denture with Livdent FB artificial posterior teeth, remarkably.<BR>3. In case of unilateral biting in eccentric occlusion, the occlusal scheme affected the pressure distribution. The pressure values increased on the nonworking side.<BR>It was concluded that the lingualized occlusion increases the denture stability and distributes the occlusal force to the supporting structures on the nonworking side.
