Autogenous tooth graft with platelet rich fibrin versus autogenous tooth graft only around immediate dental implant

Objective: This trial was conducted to compare between autogenous fresh tooth graft with/without platelet rich fibrin around immediate dental implant. Patients and methods: This controlled randomized clinical trial was carried out on 12 patients over the age of 18 who required dental extractions of single- or multi-rooted teeth, who were also delayed candidates for osseointegrated implants. They were equally divided into two groups; group (1): Autogenous fresh tooth graft around immediate dental implant placement with platelet rich fibrin and group (2): Autogenous fresh tooth graft around immediate dental implant placement without platelet rich fibrin. Results: The mean value of horizontal bone loss in group (1) and group (2) at 6 months 0.077 (0.065 -0.130) and 0.595 (0.450 - 0.690) respectively with statistical significant differences between two groups. While vertical bone loss in group(1) and group(2) at 6 months (0.510(0.480 -0.530) and (1.490(1.400  - 1.640) respectively with statistical significant differences between two groups. The mean value of  implant stability quotient for group (2) at 3 months was 70.50 ± 3.56 ISQ, and increased to 77.67 ± 5.61 ISQ at 6 months, which was statistically significant
