摘要/Abstract

摘要： 目的评价不植骨上颌窦内提升术在剩余牙槽骨高度为（RBH）3-8mm的患者种植修复中应用的临床效果。方法对上颌后牙缺失，接受上颌窦内提升术，同期植入种植体但未进行植骨的10例患者进行回顾调查研究，这些病例术前的RBH范围均处于3~8 mm范围内。参照Cochran提出的种植体成功标准进行临床随访。通过影像资料测量术前种植体近远中位置RBH，并与术后1年相同位置进行对比，分析骨量变化。结果 10例病例的种植体均存留，根据标准评价1年种植成功率100%。病例术前RBH处于3.0-7.2mm之间，术后1年种植体边缘骨高度为3.6-9.2 mm，两者比较存在统计差异（P＜0.05），种植区骨变化量（1.1±0.5）mm。结论上颌窦内提升术在不植骨的条件下对于RBH 3-8mm的患者具有较好的短期临床效果。

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.
