摘要
目的:探讨基于锥形束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(P<0.05);二期种植修复后,在种植后6个月、种植后12个月,三维组患者的PES评分均高于传统组(P<0.05);二期种植修复后6个月、种植后12个月,三维组患者的牙槽骨顶部宽度、牙槽骨高度、牙槽骨中部骨宽度增加值与传统组比较,差异无统计学意义(P>0.05);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。
Objective To explore the effect of personalized titanium mesh combined with GBR based on cone beam CT three-dimensional reconstruction to repair alveolar bone defects and its influence on implant aesthetics.Methods Eighty-six patients in our hospital who intend to receive titanium mesh combined with GBR to repair alveolar bone defects,43 of which received personalized titanium mesh based on cone beam CT three-dimensional reconstruction combined with GBR for alveolar bone repair(three-dimensional group),and another 43 patient used traditional titanium mesh combined with GBR technology for alveolar bone repair(traditional group).The increase in alveolar bone width,alveolar bone height,and alveolar bone volume increase before surgery,2 months after surgery,4 months after surgery,and 6 months after surgery were compared between the two groups.The labial aesthetic score and bone resorption at the implant site after implant restoration.Results At 4 months and 6 months after operation,the increase in alveolar bone width,alveolar bone height,and alveolar bone volume increase in the three-dimensional group were greater than those in the traditional group,and the difference was statistically significant(P<0.05).After the second-stage implant restoration,6 months after implantation and 12 months after implantation,the PES scores of the three-dimensional group were higher than those of the traditional group(P<0.05).At 6 months after the second-stage implant restoration and 12 months after the implant,the increase in the width of the alveolar bone,the height of the alveolar bone,and the width of the middle of the alveolar bone in the three-dimensional group was not statistically significant(P>0.05).The incidence of titanium mesh exposure in the three-dimensional group was 4.65%,the incidence of implant loosening was 2.33%,the incidence of titanium mesh exposure in the traditional group was 11.63%,and the incidence of implant loosening was 6.98%.There was no significant difference between the two groups(P>0.05).Conclusion The
