摘要

The effect of platelet-rich fibrin (PRF) on bone healing around dental implants in areas of poor bone quality has not been studied. The aim of this study was to evaluate the stability of implants placed in the posterior maxilla, with or without the use of PRF, during the healing period. A split-mouth randomized clinical trial was performed. Twenty patients with missing teeth in the molar region of the maxilla, requiring bilateral implants, were included. PRF was used on one side (group 1); no PRF was used on the other (group 2). Implant stability was assessed by resonance frequency analysis (RFA) at 2, 4, and 6 weeks after placement. At 2 weeks, the mean ISQ was 60.60 +/- 3.42 in group 1 and 58.25 +/- 3.64 in group 2; at 4 weeks it was 70.30 +/- 3.36 in group 1 and 67.15 +/- 4.33 in group 2; at 6 weeks it was 78.45 +/- 3.36 in group 1 and 76.15 +/- 2.94 in group 2. Significant differences in RFA were found between the groups at 2 weeks (P = 0.04), 4 weeks (P = 0.014), and 6 weeks (P = 0.027) after placement. The study results suggest that the use of PRF may enhance the post -insertion stability of dental implants placed in the posterior maxilla during the healing period.
