Evaluating patient experiences with implant-supported crowns versus removable dentures

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess how patients perceive their oral function and quality of life when posterior teeth are replaced with implant-supported crowns compared to removable partial dentures (RDPs) or no treatment. It will also develop and validate new 3D digital methods for measuring occlusal contacts and analyze their relationship with masticatory ability. Additionally, the study will compare the biological and technical outcomes of splinted versus non-splinted implant-supported crowns over time. Participants will include partially edentulous individuals in good health who require fixed implant-supported crowns.
