Abstract

Aim of the study: The aim of this study is to compare the effect of PRF versus xenograft on implant primary stability after closed sinus elevation in the maxillary posterior area .
MATERIAL AND METHODS:
Patients were divided in to two equal groups:
Group A: closed sinus lifting by Osteotome using PRF as grafting material with implant placement in 8 partially edentulous patients.
Group B: Closed sinus lifting by osteotome using xenograft as a grafting material with implant placement in 8 partially edentulous patients.
After implant placement, Smart peg was placed on implant and Ostell is used to record ISQ. Implant stability was measured intraoperative and at week 2, 4, 6, 8 and 10 for both groups. The collected results were tabulated and statistically analyzed.
Results:
The study results showed that there was no statistically significant difference between (PRF) and (Xenograft) groups in ISQ reading.



Conclusion:
Maxillary sinus elevation by osteotome technique and using PRF or xenograft as a grafting material is a predictable and effective procedure for correcting limited bone resorption in posterior areas of the maxilla.
