Efficiency of advanced-PRF usage in the treatment of alveolar cleft with iliac bone graft: A retrospective study

Abstract : The aim of this study was to evaluate the efficiency of a new alveolar bone grafting protocol using advanced-PRF (a-PRF) by comparing the volumes of newly formed bone after a bone graft combining autogenous iliac crest bone with either PRF or a-PRF. Patients presenting with unilateral or a bilateral alveolar cleft were included retrospectively in two groups: one group was grafted using cancellous iliac crest bone with PRF (PRF group), whereas for the other group the same procedure was followed using a-PRF (a-PRF group). CBCT scans were performed 3 months preoperatively and 6 months postoperatively. The volume of newly formed bone was measured by subtracting the postoperative cleft volume from the preoperative cleft volume. The mean volume of newly formed bone was compared between the two groups using Student's t-test. Twenty-four patients were included, with 12 allocated to each group. Forty-eight CBCT scans were analyzed. The mean volume of newly formed bone was 0.29 (+/- 0.09) cm(3) in the a-PRF group, versus 0.20 (+/- 0.08) cm(3) in the PRF group (Student's t-test, p = 0.024). The percentage of newly formed bone was 60.4 (+/- 10.4) % in the a-PRF group versus 51.4 (+/- 18.4) % in the PRF group (Student's t-test, p = 0.165). Our study demonstrated improved bone regeneration in the a-PRF group. While bearing in mind the limitations of this study, the a-PRF procedure should be adopted in cleft bone grafting whenever possible. (C) 2021 European Association for Cranio-Maxillo-Facial Surgery.
