The effectiveness of the osteotome technique for sinus augmentation was evaluated using cone beam computed tomography (CBCT) analysis. Clinical results of two-stage sinus floor elevation using the osteotome technique performed on 15 patients at the Nakajima Dental Clinic between 2006 and 2013 were evaluated retrospectively. CBCT imaging revealed that the maxillary sinus floor was elevated by an average of 7.28 mm (SD 1.62) immediately following surgery, with a mean bone height of 9.55 mm (SD 1.43). In all cases, the osteotome technique provided sufficient bone height for implant placement. No pre- or postoperative complications (eg, mucosal perforation) were reported. The minimal surgical stress and morbidity further underscore the practicality of this approach for two-stage maxillary sinus floor augmentation.
