    Assessment of the effectiveness of platelet rich fibrin in the treatment of Schneiderian membrane perforation
    (Wiley, 2017) Oncu, Elif; Kaymaz, Esin
    BackgroundThe objective of this study is to evaluate the effect of Platelet rich fibrin (PRF) treatment of maxillary sinus membrane perforation on bone formation and new vascular supply and the success of dental implant survival rate. MethodsThe dataset for this retrospective study consists of patients who received sinus augmentation using the lateral wall technique. A total of 16 patients (20 sinuses) the patients without sinus membrane perforation (10 maxiller sinus area with sinus floor augmentation) and with Schneiderian perforation (10 maxiller sinus area repairing with PRF and augmented sinus floor area) were included in this study. The bone height was measured by comparing the preoperative and postoperative dental CBCT scans. Histological sections were evaluated for possible vasculogenesis augmented sinuses area. ResultsIn both groups, it was observed that the possible vasculogenesis augmented sinuses area increased. Implant survival rates in both groups found that one hundred percent and any bone loss around implants were not observed. An apparent increase in alveolar bone height was observed and measured in CBCT scans. ConclusionsPRF can be considered as an alternative material for repairing sinus perforations because it is fully autogenous and easy manipulated.
