摘　　要：目的评价骨劈开联合骨挤压及引导骨组织再生技术(GBR)同期植入种植体用于前牙美学区牙槽骨水平宽度不足的临床疗效。方法以CBCT检查术前、术后牙槽骨的形态和骨量,选取唇舌向牙槽骨宽度介于2.5 mm～4.5 mm的13例前牙种植区剩余骨量不足患者,采用微创骨锯、超声骨刀等方法行前牙(美学区)牙槽骨劈开术,骨扩张、同期植入23枚种植体,并辅以GBR技术,术后4个月～6个月内完成Ⅱ期修复。结果 23枚种植体均获得良好的初期稳定性,Ⅱ期修复时X线片显示种植体周围形成良好的骨结合,种植体稳定性良好,唇侧牙槽突较丰满,牙龈形态、色泽、与邻近组织基本一致。随访0.5年～2年,种植修复体稳定,无松动,功能使用良好,没有明显的种植体周围炎发生。结论前牙美学区牙槽骨水平宽度不足患者,采用骨劈开联合骨挤压及骨引导再生技术行同期种植体植入,可增加骨量,拓宽种植手术适应证,并有利于支持及恢复缺牙区软组织外型,保证种植体的美学效果。Objective To evaluate the clinical treatment effects of oral implant in anterior region with narrow boneridge,using the techniques of bone splitting,bone condensing and guided bone regeneration. Methods We collected 13patients with teeth missing in anterior region with narrow bone ridge. The patients had sufficient vertical bone height but the bonewidth only 2.5mm to 4.5mm at the implant sits , We placed 23 implants using the techniques of bone splitting,bone condensingand guided bone regeneration. After 0.4- 0.6 years of follow-up,we evaluated the effects based on the clinical examination andX-rays. Results The 23 implants had obtained the good initial stability, Ⅱ repair when X ray film shows good around implantbone union, implant stability is good, the lip side alveolar fuller, gum shape, color, and adjacent tissue. During the follow-upperiod of 0.5 to 2 years, the implant prosthesis was stable without loosening and good functional use without obviousperi-implantitis. Conclusion The techniques of bone splitting,bone condensing and guided bone regeneration are valuablefor narrow bone ridge in anterior region. They preserve the bone quality and decrease the pain of patients,and achievesatisfactory effects.
