Abstract

The effect of platelet rich fibrin (PRF) in association with Hydroxyapatite (HA) graft material for bony regeneration around immediate implants was studied and compared in twenty patients planned for having immediate dental implants following extraction of mandibular anterior teeth. Patients were divided into two groups. Group A In which 10 immediate implants were inserted into the extraction socket of mandibular anterior teeth and the gap around the implant was grafted with Hydroxyapatite granules. Group B In which 10 immediate implants were inserted into the extraction socket of mandibular anterior teeth and the gap around the implant was grafted with Hydroxyapatite granules associated with platelet rich fibrin (PRF). The results of this study showed that Group B showed statistically significantly higher mean bone density than Group A. We concluded that Immediate placement with delayed loading dental implants remains the procedure of choice for achieving proper Osseo integration, Immediate dental implants with HA graft material associated with PRF was significantly superior than HA graft only. PRF is a viable and biocompatible autologous biologic material, and its placement is easier and does not require a skill when compared to collagen membrane.
