Efficacy of Platelet Rich Plasma on Implant Stability in Maxillary Implant Supported Overdenture.

Abstract

This study was performed to evaluate the effect of Platelet Rich Plasma on implant stability and bone height changes in Maxillary Implant Supported Over denture. Ten patients who are completely edentulous were carefully chosen from the outpatient clinic, Department of Removable Prosthodontics, Faculty of Dentistry, Ain-Shams University to participate in this study seeking for prosthetic rehabilitation to Participate in this study. Patients were precisely selected and thoroughly examined in an attempt to reduce human variables and eliminate any factor that might adversely affect the result in the study. Standard clinical and laboratory techniques were followed for the construction of the complete dentures for all patients For all patients, four implant were inserted into premaxillary region in alternative method, 2 implants treated with PRP and 2 conventional implants starting with conventional one in the right side. So we have two groups of implant: Group I: Implants in this group were inserted directly without exposing to PRP (control group). Group II: Implants in this group received PRP at a predetermined exposure protocol (study group). After four months the healing cap was removed and replaced by the functional abutment (ball & socket). The metal housings were placed over their corresponding abutments, the metal housings were picked up to the fitting surface of the upper denture using pink self-cure acrylic resin while the patient was occluding in centric relation. The excess self-cure acrylic resin in the fitting surface and flanges was removed, denture finishing and polishing were done.

Implant stability was assessed at all follow-up visits using Osstell device and osstell smart peg. The score was determined according to the following:
