Various maxillary sinus floor augmentation techniques were common performed and in the most cases, many kinds of bone graft materials were used. The graft materials are autogenous bone or other biomaterials of human, animal or synthetic origin. But these cases report describes a new surgical technique by which dental implants are inserted in a void space created by elevating the sinus membrane without additional graft material in atrophic posterior maxilla. We created lateral bony window using piezoelectric device and elevated the schneiderian membrane in ten patients. Dental implants were simultaneously placed and lateral window prepared was covered with non-resorbable membrane in five patients and was repositioned with bony window in five patients, without any bone graft. From the clinical and histological results, it is found there is potential capacity for bone formation and placement of implants in the maxillary sinus without the use of bone grafts or bone substitutes.
