摘要：

目的    评价前牙区牙槽骨水平宽度不足的患者联合应用骨劈开、骨挤压和骨引导再生术行同期种植体植入的临床效果。方法    2004—2009年福州市第一医院口腔科就诊的前牙区牙缺失伴前牙区牙槽骨水平宽度不足的种植患者28例，联合应用骨劈开、骨挤压，填入骨粉，行骨引导再生术后同期植入40颗种植体，术后4 ～ 6个月内完成上部修复。术后1年，通过临床检查、全景片等观察效果。结果    术前、后牙槽骨平均宽度分别为 （3.2±0.89）mm、（6.5±0.75） mm，平均增加了（3.3±0.34） mm。术后牙槽骨宽度与术前相比，差异有统计意义（t =2.47，P < 0.05）。术后无明显并发症发生，种植体行使功能良好，仅1例患者的1颗牙种植失败，种植近期成功率达97.5%。结论    对前牙区牙槽骨水平宽度不足的患者，联合应用骨劈开、骨挤压和骨引导再生术行同期种植体植入，可增加骨量，获得种植体的同期植入，减少患者痛苦，改善种植修复的临床效果。

Abstract:

Objective    To evaluate the clinical treatment effects of implant in anterior region with narrow bone ridge， using the techniques of bone spliting， bone condensing and guided bone regeneration. Methods    We collected 28 patients with teeth missing in anterior region with narrow bone ridge. We placed 40 implants using the techniques of bone splitting， bone condensing and guided bone regeneration. After 1 year of follow-up， we evaluated the effects based on the clinical examination and panoramic radiograph. Results    There was no obvious complications. Good aesthetic and functional outcomes were observed. With 1 implant lost，we got 97.8% survival rate. Conclusion    The techniques of bone splitting， bone condensing and guided bone regeneration are valuable for narrow bone ridge in anterior region. They preserve the bone quality and decrease the pain of patients， and achieve satisfactory effects.
