Long-term success of sinus augmentation using various surgical approaches and grafting materials

Abstract

Two hundred twenty-two sinus augmentation procedures were performed using one of three techniques: crestal approach; lateral approach; or lateral approach with simultaneous implant placement. Forty-one of these sinus augmentation procedures were performed in conjunction with buccolingual ridge augmentation. Of the 222 procedures, 217 (97.7%) were successful. Of 510 implants placed in augmented sinus areas, 495 (97.0%) were deemed successful by the criteria of Albrektsson et al for up to 73 months in function. Clinical considerations in the execution of such therapy are discussed.
