【摘要】 目的为解决上颌后牙缺失后牙槽骨高度不足、种植体易穿入上颌窦腔导致种植失败这一难题。方法作者对９例患者１２侧上颌窦行上颌窦提升、植骨及同期种植体植入术，术后随访平均时间１４个月（１０～２３个月）。结果无种植体松动或脱落，无上颌窦炎症发生，Ｘ线复查显示种植体周围无阴影；有８例患者颏部取骨术后下唇出现暂时性感觉迟钝或麻木，均自愈。结论上颌窦提升、植骨及同期种植体植入术对解决上颌后部牙齿缺失后牙槽骨高度不足、种植困难是行之有效的方法，并提出了适应证，对手术方法、植骨技术方面的注意点进行了讨论。更多还原

【Abstract】 Objective To study the effect of maxillary sinus floor lifting by bone graft for immediate implantation Methods 12 maxillary sinus underwent sinus floor bone graft and simultaneously 24 implants olacement. The mean time of follow up was 14 months. Results There were no implant loose or lost, no clinical complaint of the maxillary sinus area, and X ray exam showed well osseointegration in 6 months postoperatively. Abnormal sensitivity of chin area were found in 8 patients after bone graft taken from chin, but the sensitivity became normal spontaneously in 3～12 months postoperatively. Conclusion Successful maxillary sinus floor bone graft with simultaneously placement of implant is predictable.更多还原
