Maxillary sinus augmentation is used for implant placement in edentulous maxilla with alveolar bone resorption. It hasrelatively few complications and a high success rate. The purpose of this study was to evaluate the prognosis for variousconditions after maxillary sinus grafting to improve insufficiency of remaining bone when placing implants in posteriormaxilla over the last 10 years. We analyzed 1,121 implants in 404 patients who underwent maxillary sinus grafting andimplantation during the last 10 years at Chosun University Dental Hospital. Statistically speaking, the implant survival ratesdid not differ significantly according to systemic disease and bone quality, implant type and surface treatment, graft materi-als, surgery stage or type of membrane. In contrast, residual bone height, approach technique and Schneiderian membraneperforation were associated with significant differences in implant survival. Overall, however, implants generally survivedwell. This study suggested that maxillary sinus grafting is a safe procedure.
