用水囊扩张法提升上颌窦底并植骨同期种植的临床研究

Clinical study of sinus elevation by water balloon and implant placement

目的探讨及评估应用水囊扩张法提升上颌窦底黏膜并同期植骨种植的临床应用效果及技术特点。方法自2006年5月至2007年11月用水囊扩张法从牙槽嵴顶入路提升上颌窦底黏膜并植骨同期行种植体植入术患者共31例，本组31例均为上颌后牙单颗牙缺失，剩余牙槽骨高度为（4.79±1.18）mm。本组患者男性16例，女性15例，年龄（41．2±11．8）岁。观察方法为临床检查及影像学检查。结果31例上颌窦底提升高度为（10.60±2．06）mm，共植入种植体31枚，均已完成种植修复，平均追踪（14.2±3.6）个月。术后未观察到明显的并发症及不良反应。1枚种植体感染于术后2周脱落，愈合3个月后再次行种植体植入，愈合良好，已完成修复。结论应用水囊扩张法提升上颌窦底黏膜并植骨同期种植，手术创伤小、临床操作简单、重复性好，近期临床效果可靠。

Objective To evaluate the clinical results and technique of minimally invasive sinus membrane water halloon elevation followed by bone augmentation and implant placement simultaneously. Methods From May2006 to November 2007 , 31 patients（male：16, femal：15; mean age：41.2 ±11. 8） were involved in the study. Clinical examination and radiographs were conducted. Results The mean residual ridge height was （4. 79 ± 1.18 ） mm and the mean elevated height was （ 10. 60 ± 2.06 ） mm. A total of 31 implants were placed and restored with the mean follow-up period of （14. 2 ± 3. 6） months. Only minor complications were observed postoperatively. One implant was lost due to infection two weeks after operation. Conclusions The procedure of minimally invasive sinus membrane water balloon elevation achieves an excellent success rate, low complication, minimal discomfort, and the short-term result is predictable.
