目的：评价上前牙区牙槽骨水平宽度不足的患者应用骨劈开、牙槽嵴扩张联合GBR技术同期植入种植体的的临床疗效。方法：2011年5月～2013年9月，选取来本院就诊的24例上前牙种植区剩余骨量不足患者，应用超声骨刀行前牙牙槽骨劈开术，骨扩张、同期植入30枚Ankylos种植体，辅以GBR技术。6个月后，平行投照根尖片、 CBCT复查，完成修复，随访1年。结果：牙槽嵴唇腭侧术前、术后平均宽度分别为（3.2±0.12） mm和（6.4±0.16）mm，差异有统计意义（t=239.024， P<0.05），牙槽骨宽度在术后基线与半年后结果相比，差异无统计意义（t=1.795， P>0.05）。结论：骨劈开、牙槽嵴扩张联合GBR技术并同期植入种植体短期临床效果较好，远期效果有待于进一步观察。

Objective: To evaluate the clinical effectiveness of bone splitting and alveolar ridge expansion associated with a guided bone regeneration with simultaneous implant placement in anterior region of maxilla where deficiency of bone mass. Methods: From May 2011 to September 2013, 24 patients with insufficient bone mass in the anterior maxilla area were simultaneous bone splitting, ridge expansion and GBR technique with 30 implant placement. 6 months later, these implants were connected to the final prosthesis after reexamination by periapical film and CBCT. The patients were followed up for 1 year. Results: The mean labial-palatal width of alveolar ridge changed from 3.2 ±0.12mm to 6.4 ± 0.16mm after operations, the mean increase were 3.2 ±0.07mm and the differences were statistically significant(t=239.024, P<0.05). The differences of means between postoperation and half a year were not statistically significant(t=1.795, P>0.05). Conclusion: Simultaneous bone splitting, rigde expansion and GBR technique with implant placement in the maxillary anterior region may achieve good clinicaleffect. We still need more evidence to support the long-term effect.
