Clinical Evaluation of Implant-secured Removable Partial Denture

Not Applicable

Terminated

• Conditions: Tooth Loss
• Interventions: Procedure: PASI; Procedure: PAC

• Registration Number: NCT02762201
• Lead Sponsor: Hospices Civils de Lyon

Brief Summary

This study aims to compare the therapeutic efficiency of implant-secured removable partial denture (PASI) with the therapeutic efficiency of the metalic standard removable partial denture (PAC) in the treatment of intermediate extended-gap (4 adjacent teeth). The therapeutic efficiency will be assessed by the 5 years-prosthetic success rate.
