Abstract

Objectives: The current study aimed clinically and radiographically to evaluate and compare the efficacy of platelet rich fibrin (PRF) versus xenograft on healing around immediate dental implants in the esthetic zone. Patients and Methods: twelve implants were inserted immediately after tooth extraction for 11 patients aged between 25 and 40 years replacing hopeless teeth in the anterior maxilla. Patients were randomly divided into two equal groups: group (I) (n=6) the jumping gap was filled with PRF, and group (II) (n=6): the jumping gap was filled with xenograft. The patients were clinically and radiographically evaluated for the following: implant stability using resonance frequency analysis (RFA), crestal bone loss and bone density. Results: All implants showed acceptable primary stability with a significant improvement in secondary stability that measured at 6 months postoperatively in both groups. The mean value of crestal bone loss and bone density with PRF and xenograft were comparable without significant differences in both groups. Conclusions: the use of PRF as a gap filling material is effective in healing around immediate dental implant in esthetic zone and can be compared with xenograft with regards to implant stability, crestal bone loss, and bone density.
