- Brief Summary
In this study, we randomly selected PRF or Bio-Oss for simultaneous implant placement with sinus graft and conducted a 9-12month follow-up observation. Our results indicated good outcomes, with a survival rate of 100% in the PRF group and 95.2% in the Bio-Oss group. A stability dip in ISQ values was also noted in both groups at 2 weeks after implant placement. The stability dip was mild in the PRF group and ISQ values were observed to be identical in the two groups at several time-points. Thus, together with the good survival rate achieved, we confirmed the efficacy of PRF. In the future, further follow-up observation of research patients needs to be conducted.
