摘　　要：目的:评价前牙美学区牙槽骨宽度不足时种植的临床疗效。方法:选取51例单颗前牙缺失伴牙槽骨宽度不足患者,分别采取骨劈开挤压术联合引导性骨再生技术(guided bone regeneration technique,GBR)(牙槽骨宽度3~5 mm,A组21例)、GBR技术(牙槽骨宽度>5 mm,B组30例)进行骨增量,术后随访18个月,观察两组种植成功率及牙槽骨变化情况。结果:A、B两组术后18个月成功率比较,差异无统计学意义(P>0.05);两组术后牙槽骨边缘骨水平比较,B组优于A组,差异有统计学意义(P<0.05)。结论:骨劈开挤压术联合GBR技术、单纯应用GBR技术均能有效增加骨量;前者较后者成骨效能更高,可应用于牙槽骨较窄的患者。Objective： To evaluate the clinical curative effect of implanting in anterior teeth aesthetic region with the deficiency of alveolar bone width. Methods： Fifty-one patients of single anterior teeth loss with insufficient alveolar bone width were selected to obtain bone augmentation by performing bone splitting condension along with guided bone regeneration technique（ GBR）（ bone width of 3 -5 mm,21 cases of group A） and GBR technique（ bone width of more than 5 mm,30 cases of group B）. And the two groups were followed up for 18 months after operations to obtain the success rate of implant and the change of alveolar bone. Results： The difference of success rate of implants in two groups 18 months after operations was not statistically significant（ P 〉 0. 05）; the changes of implant bone level between before and after operations in both two groups were statistically significant（ P 〈 0. 05）. Conclusion： Both the bone splitting condension technology combined with GBR technology and the single GBR technology can effectively increase the bone mass,and the former,which has higher osteogenic efficiency compared to the latter,can be used in patients with narrow alveolar bone.
