摘要
目的:研究比较上后牙缺失牙槽嵴高度不足患者,根据上颌窦底牙槽嵴骨高度不同,选用开窗植骨或闭合冲压提升上颌窦底,同期种植牙的治疗效果。方法:43例(55侧)上后牙缺失患者,其中34例(40侧)窦底牙槽嵴骨高6~10mm者行闭合冲压上颌窦底提升术,其余9例(15侧)骨高2~5mm者行开窗植骨上颌窦底提升手术,均同期完成一期种植体植入手术。结果:所有患者术后未出现上颌窦炎症,9例行开窗植骨上颌窦底提升手术的患者,无窦膜穿孔,平均提升窦底高度5.8mm,26颗种植体平均负载30个月,种植体稳定,骨结合状况良好。34例行闭合冲压上颌窦底提升术的患者,平均提升窦底高度4.3mm,手术操作中有3颗发生可察觉窦膜破孔,发生率为4.1%(3/73),在73颗种植体中,有2颗种植体失败,71颗种植体平均负载23个月,种植体稳定,未见明显骨吸收,成功率97.3%(71/73)。结论:闭合冲压上颌窦底提升术是一种微创、简单、可靠用于上颌后牙上颌窦底牙槽嵴骨高度不足的种植临床技术,临床上应根据上颌窦底牙槽嵴骨高度不同,选用开窗植骨或闭合冲压提升上颌窦底。
Objective: To study the effect of maxillary sinus lift with bone graft or internal sinus floor elevation with sinmltaneous placement of implants according to different height of alveolar ridges. Methods : 43 patients suffered the loss of up posterior teeth. 34 cases whose bone height of maxillary sinus floor was between 6 - 10mm underwent internal sinus floore elevation, and other 9 cases whose bone height between 2 - 5ram underwent maxillary, sinus lift with bone graft, all cases were simultaneously placed implants. Results: There were no clinical complaints of maxillary sinusitis for all cases. 9 cases who underwent maxillary, sinus lift with bone graft had not detectable Schneiderian membrane perforation during operation procedure, and the mean increase height was 5.8mm. A total of 26 implants had loaded for 30 months and were stable. And well osseointegration on X - ray film. 34 cases who underwent internal sinus floor elevation showed the mean increase of 4.3mm. There were 3 implants which had detectable Schneiderian membrane perforation during operation procedure, and 2 implants lost. The rest implants 71 have loaded for 23 months and were stable and well osseointegration on X -ray film. Conclusion : Two sinus lift approaches show desirable clinical results. Internal sinus floore elevation is a mini - trauma and reliable clinical technique for sinus lift.
