Abstract Objective: To investigate the clinical outcome of platelet-rich fibrin (PRF) and piezosurgery in lateral sinus lift (LSL). Methods: Fifty-six patients from Stomatology Hospital of Wenzhou Medical University were randomly divided into two main groups:group A and group B. The piezosurgery was used in group A (n=28) for LSL with PRF (Group A1, n=14) or without PRF (Group A2, n=14), and the traditional surgery was performed in group B (n=28) for LSL with PRF (Group B1, n=14) or without PRF (Group B2, n=14). The feelling of treatment and postoperative pain (postoperative days 1, 2, 3, and 7) were analyzed by visual analog scale (VAS), and the perforation rate of maxillary sinus membrane and the number of analgesics taken (postoperative days 1, 2, 3, and 7) were also recorded. All of these data were analyzed with SPSS 17.0 software. Results: A significant lower VAS score (the feeling of treatment) was found in group A, compared with group B (P<0.05). Meanwhile, the perforation rate of maxillary sinus membrane of group A was lower than that of group B (P<0.05). The difference of postoperative pain and the number of analgesics taken in group A1-B1 and group A2-B2 were both not significant (P>0.05). However, a significant difference of postoperative pain and the number of analgesics taken was found in group A1-A2 and group B1-B2 (P<0.05). Conclusion:
Piezosurgery is safe and reliable in LSL, which can also reduce intraoperative and postoperative discomfort feeling when combined with PRF
