Abstract :Objective: Modern implant therapy concept is aimed to accelerate and enhance the osseointegration. Considering this, some interventions at bone metabolism have been defined utilizing by modifying the implant surface, using pharmacologic agents, biomaterials and bio-active molecules. PRF insert ignore into journalissuearticles values(Platelet Rich Fibrin); among the platelet derived factors insert ignore into journalissuearticles values(living bio-active molecules); have been under research in recent studies and literature. The aim of this study is evaluation of the PRF usage on osseointegration for immediate implantation in maxillary and mandibular posterior zone by the RFA insert ignore into journalissuearticles values(Osstell); technique. Materials and Method: A clinical study was conducted on sixteen insert ignore into journalissuearticles values(16); fresh extraction sockets on 8 males and 8 females patients at maxillary and mandibular posterior zone. Bone level implants were inserted immediately. The participants were assigned to 2 group randomly. Group I insert ignore into journalissuearticles values(Test Group; PRF+Allogreft);. Group II insert ignore into journalissuearticles values(Control Group; Only Allogerft);. For all implants a mixture of PRF and allograft placed around the marginal aspects in order to compensate a dehiscence of bone. PRF membranes were placed as dual layers bidirectionally and the healing abutments were placed simultaneously through the PRF membranes in the Test Group. In Control Group, healing abutments only placed without any layer. After implant placement, RFA values were measured as ISQ values immediately intra-operatively and post-operatively at 1st, 2nd and 3th months by utilizing Osstell. Results: Only 11 participants insert ignore into journalissuearticles values(6 male,5 female); co-operated with follow phase of study. 5 participants did not show up for measurement on time. There was no implant failure. The mean average ISQs values of Test group insert ignore into journalissuearticles values(PRF+Allograft); were measured as 69.57 at opertion day, 72 at 1st month, 78.28 at 2nd mount, 79.71 at 3th month. Average values of Control group insert ignore into journalissuearticles values(Only allograft); were measured as 67.5 at operation day, 69.75 at 1st month, 75.5 at 2nd month, 76.5 at 3th month. There was no significant differences between the groups by the statistically, only slightly different. Conclusion: It was observed that this study with limited number of participants have revealed a slightly but non-significant positive effect of PRF usage on implant stability in immediate implantation post-extraction in posterior zone by RFA technique. Considering, further clinical studies with larger study groups must be performed in order to evaluate the potential effect of PRF on implant stability.
