Evaluation of Implant Stability after Application of Platelet Rich Fibrin in Mandibular Posterior Ridge Splitting and Simultaneous Implant Placement Versus Xenograft Application: A Randomized Clinical Trial

Aim of the Study: The purpose of this study aimed to answer a clinical question whether the use of plateletrich fibrin after ridge splitting with simultaneous implant placement will enhance implant stability incomparison with xenograft or not.Materials and Method: sixteen patients were divided into 2 equal groups (Group I & Group II). Patientsin both groups underwent surgical ridge splitting for narrow edentulous posterior mandibular ridge withsimultaneous implant placement. In Group I, platelet rich fibrin used as a graft material around the implantin between buccal and lingual cortices. In Group II, Tutogen® xenograft used as a graft material around theimplant in between buccal and lingual cortices.. Each patient was assessed forimplant stability measured byOsstellTM by means of resonance frequency analysis (RFA)which is recodedas Implant Stability Quotient(ISQ)values first intraoperative then at intervals 3 months, 6months and 9 months postoperatively.Moreoverthe bone relative density has been evaluatedby cone beam computed tomography (CBCT) immediate ostoperativeand 6 months later.Results: A higher mean value of ISQ was recorded in Group II than in Group I with no statistically significantdifference (p=0.246).In addition a higher mean value of bone density was recorded in Group I than in GroupII with no statistically significant difference (p=0.601).Conclusion: Platelet rich fibrin could be used as grafting material from natural source, non-immunogenic,without xenopathy after ridge splitting in posterior mandibular region as a technique with time and costsaving with least morbidity.
