Clinical Performance and Stability of Different Types of Implant Supported Overdenture

Study Overview
=================
Brief Summary
-----------------
A Total number of 36 implants were installed in 6 patients having mandibular single denture. The patients were divided into two groups according to the definitive prosthesis. Group I received ball and socket retained mandibular implant overdenture while Group II received cement retained implant supported fixed bridges.

Detailed Description
-----------------
Implant's stability, clinical performance (gingival index, pocket depth, plaque index and bleeding on probing) and patient's satisfaction were performed after 15, 30,60 and 90 days after prosthesis delivery
