5. Study Description
Brief Summary
The purpose of this study is to find the difference between patient satisfaction, masticatory performance and cost between two occlusal schemes for complete denture prosthodontics.
Detailed Description
Two occlusal scheme applied to complete denture prosthodontics has been compared in RCT. This will have clinical benefit for deciding which occlusal scheme is better according to patient conditions. It will also have impact on dental educational curriculum.
