Objectives: The aim of this study was to evaluate the implant success with regard to effects of the sinus socket lifting procedure that not using augmentation material up to 10 years.
Methods: The study group consisted of 70 patients (51 females and 19 males) with edentulous posterior maxilla up to 10 years (1996 to 2006). Implant placement combined with sinus socket lifting surgery was performed, and 121 implants were inserted. Sinus membrane was maintained with implant. The increase in the amount of bone volumes was calculated by the
computerized-tomography scanning equipment scan of a cross section.
Results: Resulting in an overall survival rate of 100%. Hypertrophy of sinus membrane was not observed. The amounts of increases in an average of the quantity of the bone volume calculated by the computerized-tomography scanning equipment scanning equipment scan to cross were a width of 8.12mm, and a height of 4.02mm.
Conclusion: Within the limits of this study, in maxillary sinus lift procedure, even if there was no bone augmentation, it turned out that stability of an implant placement could be achieved.
