    [摘要]目的：探討基于锥形束CT三维重建的个性化钛网联合引导骨再生技术(GBR)修复牙槽骨缺损的效果及对种植美学指标的影响。方法：选取笔者医院拟接受钛网联合GBR进行修复牙槽骨缺损的86例患者为研究对象，随机分为两组。三维组：43例，接受基于锥形束CT三维重建的个性化钛网联合GBR进行牙槽骨修复;传统组：43例，患者采用传统钛网联合GBR技术进行牙槽骨修复;对比两组患者在术前、术后2个月、术后4个月、术后6个月的牙槽骨宽度增加值、牙槽骨高度增加值、牙槽骨量体积增加值及两组实施种植体修复后的唇侧美学评分及种植点位骨吸收量。结果：术后4个月、术后6个月，三维组患者的牙槽骨宽度增加值、牙槽骨高度增加值、牙槽骨量体积增加值均大于传统组，差异具有统计学意义(P0.05);三维组的钛网暴露发生率4.65%、种植体松动发生率2.33%，传统组的钛网暴露发生率11.63%、种植体松动发生率6.98%，两组比较差异无统计学意义(P>0.05)。结论：基于锥形束CT三维重建的个性化钛网联合GBR修复牙槽骨缺损有利于促进牙槽骨形成，对于改善二期种植后美学效果有一定的帮助。
