The basic principle of osseointegration, as defined by Branemark, is based on establishing a structural and functional connection between the living bone and the implant surface [Conventionally, fissure and round burs were used to harvest grafts from the retromolar region. However, the use of diamond discs, microsaws and piezosurgery [Due to these different results in the literature, it is difficult to conduct a meta-analysis comparing piezosurgery with the conventional method in an important issue such as donor site morbidity. Since the major criticism about piezosurgery is the slowness of the device, in this randomized controlled study, we aimed to compare the piezosurgery method with the conventional rotary method in autogenous graft harvesting from the retromolar ramus focusing on the osteotomy time. In this study, our primary aim was to test the null hypothesis that there is no difference in osteotomy times between the groups. Our secondary aims were to statistically compare pain, trismus, and edema and to report possible postoperative complications.
