Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
