ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical results of osteotome sinus floor elevation (OSFE) without grafting combined with simultaneous implant placement.</p><p><b>METHODS</b>A total of 65 patients underwent maxillary sinus floor elevation from alveolus without any bone grafting from January 2000 to December 2008 and 96 implants were placed in the maxillary posterior edentulous region simultaneously. Clinical and radiography examinations were performed. The residual bone height ranged from 5 to 8 mm and the mean bone height was (6.78 ± 1.04) mm. The mean following period was 33.4 months. Statistical analysis was performed by chi square test.</p><p><b>RESULTS</b>Ninety-five of 96 implants were clinically stable and functioned without any pain and other complaints. One implant was extracted 15 days after operation because of mobility and the other implants obtained osseointegration. The mean implant protrusion length was 2.6 mm, ranging from 1 to 5 mm. Different degree of new bone formation was observed in 51 (54%) of implants. New maxillary sinus floor outline was observed in 33 (35%) of implants and there was no obvious new bone in 11 (12%) of implants. There was no significant deference between the implant protrusion length and sinus floor remodeling.</p><p><b>CONCLUSIONS</b>Under strict indications, the clinical results of OSFE without bone grafting combined with simultaneous implant placement were predictable in short term. The new sinus floor formation was not related to the implant protrusion length.</p>
