不植骨上颌窦内提升术种植的临床疗效观察

Abstract

Abstract: Abstracts: Objective To assess the clinical success of dental implants placed in atrophic maxilla, in which the residual bone height (RBH) was between 3-8 mm, using osteotome sinus floor elevation (OSFE) without grafting. Methods This study enrolled 10 maxillary posterior tooth loss patients with a RBH of 3-8 mm. After an OSFE without grafting was performed, the implants were placed. Follow-ups were conducted at 12 months after crown placement. Clinical and radiographic parameters were evaluated. Statistical analysis was performed to analyze the RBH values before and after placing implants. Results In 10 patients, all implants were retained. At 1 year, the implant survival rate was 100% according to the evaluation standard. The RBH before implant therapy was between 3.0 and 7.2 mm, while the marginal bond level after implanting was between 3.6 and 9.2 mm. The change of the marginal bond level was 1.1±0.5mm. Conclusions According to the current evidence, high survival rate could be achieved in implant therapy in the atrophied posterior maxilla, following OSFE without grafting within 1-year follow-up.
