Comparison of clinical and radiological outcomes using crestal approach sinus kit and piezoelectric surgery for sinus membrane elevation: A prospective clinical trial

Background: To overcome the drawbacks of sinus floor augmentation procedures newer surgical techniques to reduce sinus perforation such as crestal approach sinus kit (CAS) and piezosurgery, which are minimally invasive procedures enabling uncomplicated sinus elevation have evolved. The aim of the present study was to investigate the performance of CAS kit compared to piezosurgery during maxillary sinus membrane elevation. Materials and Methods: A total of 40 subjects requiring maxillary sinus membrane augmentation for rehabilitation with implant prosthesis in posterior maxilla were included in the study. The current study was a prospective clinical trial where osteotomy and sinus elevation was done using CAS kit in Group 1 and piezosurgery in Group 2. Platelet ‑rich fibrin was placed in osteotomy site and dental implants were inserted. Implant stability was evaluated at baseline and 3 months. Crestal bone loss was measured at 3, 6, and 12 months. Apical bone gain was measured at 6 and 12 months. Intragroup comparison of the study groups was done by Pair ed t‑test, ANOVA test, and Friedman test. Intergroup comparison was done by unpaired t‑test and Mann–Whitney U‑test. P
