摘　　要：目的观察和评价上颌窦底骨高度小于5mm行上颌窦内提升术的临床效果。方法选择42例上颌后牙缺失患者,剩余牙槽骨高度小于5mm,其中22例行侧壁开窗上颌窦底提升术同期植入植体28枚(侧壁开窗组),20例行上颌窦内提升术同期植入植体24枚(内提升术组)。术后6个月,行二期手术及上部结构修复。术后6、12、24、36个月随访,检查2组病例有无种植义齿的修复并发症。结果 42例患者52枚植体,1枚种植体在负重12个月时因种植体周围炎失败,余植体均未发生感染、上颌窦炎等术后并发症,骨结合良好,种植体稳定,种植义齿成功率为98.1%。侧壁开窗组和内提升术组剩余牙槽骨高度为(3.60±0.97)mm、(3.49±0.88)mm;术后36个月,2组窦底骨提升高度为(4.33±0.73)mm、(4.25±0.93)mm,2组比较差异无统计学意义(均P>0.05)。结论上颌窦内提升术创伤小,上颌窦底骨高度小于5mm行上颌窦内提升术是一种有效的方法。ABSTRACT:Objective To observe and evaluate the clinical efficacy of osteotome sinus floor ele-vation in patients with residual alveolar bone height <5 mm.Methods Forty-two maxillary pos-terior tooth loss patients with residual alveolar bone height < 5 mm were divided into two groups.In maxillary sinus antrostomy group(n = 22),maxillary sinus floor elevation was per-formed by a lateral approach and 28 implants were placed simultaneously.In osteotome sinus floor elevation group (n = 20),maxillary sinus floor elevation was performed and 24 implants were placed simultaneously.The second-stage surgery and superstructure repair were carried out 6 months after operation.Patients were followed up for 6,12,24 and 36 months to observe the com-plications of implant dentures.Results One implant was lost due to peri-implantitis after 12 months of loading.No infection,maxillary sinusitis and other complications occurred in other 51 implants.These patients had good osseointegration and stable implants.The implant success rate was 98.1%.The residual bone height was(3.60±0.97)mm in maxillary sinus antrostomy group and(3.49±0.88)mm in osteotome sinus floor elevation grouy.After 36 months of follow-up,the endo-sinus bone gain was(4.33 ± 0.73)mm in maxillary sinus antrostomy group and(4.25 ± 0.93)mm in osteotome sinus floor elevation group.No significant difference in endo-sinus bone gain was found between the two groups(P >0.05).Conclusion Osteotome sinus floor elevation&nbsp;is effective for maxillary posterior tooth loss and produce minor trauma in patients with residual alveolar bone height <5 mm.
