THE EFFECT OF PLATELET RICH FIBRIN ( PRF) VERSUS XENOGRAFT IN CLOSED SINUS LIFT WITH IMPLANT PLACEMENT ON IMPLANT STABILITY IN MAXILLARY POSTERIOR AREA Randomized Clinical Trial

Abstract

Aim of the study: The aim of this study was to compare the effect of PRF versus xenograft on implant primary stability after closed sinus elevation in the maxillary posterior area. Material and methods: Sixteen male and female patients were selected from the Outpatient Clinic, faculty of Oral and Dental Medicine Cairo University. All patients fulfilled the following criteria: Presence of edntulous area in posterior maxilla and bone height at least 5-6 mm below the maxillary sinus at maxillary posterior area. Patient's age ranged from 25 to 45 and they all had good oral hygiene. Results: The study results showed that there was no statistically significant difference between (PRF) and (Xenograft) groups in ISQ reading. Conclusions: 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. Both xenograft and PRF can be used to increase primary stability of simultaneous implant placement with closed maxillary sinus elevation. Further studies are needed with more follow up periods to evaluate healing capacity.
