摘要
目的观察冲压式上颌窦底提升术（osteotome sinus floor elevation，OSFE）不植骨并同期植入种植体的临床疗效及技术特点。方法白2000年1月至2008年12月对65例患者经牙槽嵴顶入路，行OSFE并同期行种植体植入术，共植入96枚种植体，手术过程中上颌窦内不植入任何骨充填材料。缺牙区牙槽骨可用骨高度为5－8mm，平均（6．78±1．04）mm。观察方法为临床和X线片检查。对种植体凸入上颌窦内不同长度、窦底改建情况进行卡方检验。结果除1例单牙种植术后15d因种植体松动、牙龈红肿取出种植体，其余64例患者随访〉5年12例，〉3年14例，〉2年28例，〉1年10例，平均随访33．4个月。96枚种植体中除1枚于种植15d后松动取出外，其余种植体均获得良好的骨结合并完成上部义齿修复，种植体周围软组织无炎症，咀嚼功能良好。种植体凸人上颌窦内1－5mm，平均2．57mm，51枚（54％）种植体根方有不同程度的新骨形成，33枚（35％）种植体根方形成了新的上颌窦底，11枚（12％）种植体根周未见明显新骨形成。统计分析显示，种植体凸人上颌窦内的长度与上颌窦底骨改建差异无统计学意义（X＾2=6．113，P=0．191）。结论应严格把握OSFE适应证；OSFE时不植骨并同期植入种植体的短期临床效果是可预期的；新的窦底形成与上颌窦底提升高度无明显相关性。
Objective To investigate the clinical results of osteotome sinus floor elevation （OSFE） without grafting combined with simuhaneous implant placement. Methods 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. Results 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. Conclusions 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.
