- Abstract
Brief Background: Rehabilitation of edentulous posterior atrophic maxilla has always been an exigent task in the field Implantology. Studies have shown, the use of Choukron's platelet rich fibrin as a sole grafting material in sinus floor and immediate implant placement leading to bone formation in the peri-implant region. Purpose of the Study: This study was conducted as novel research where, Direct Sinus Membrane elevation and simultaneous Implant placement without any bone graft resulted in bone formation in sub-antral space. This study compares and evaluates the bone formation with the help of Cone Beam CT Scan (CBCT) in sub-antral space following direct sinus membrane elevation and simultaneous implant placement and platelet rich fibrin as the sole graft. Materials and Methods: 48 patients who fulfill the inclusion criteria were divided as Group I-direct sinus membrane elevation and implant placement without any graft and Group II-direct sinus membrane elevation and implant placement along with PRF as sole graft. Results and Analysis: Unpaired't test' was used where, we 'p' value was compared with the level of significance. On comparing the peri-implant bone density in Hounsefield units, in CBCT scans; the bone density was more in group II which was statistically significant (p<0.05). Summary and Conclusions: PRF has proved to be a valuable autologous augmenting material in direct sinus membrane elevation and simultaneous implant placement in edentulous posterior maxilla.
