摘　　要：目的:探讨于牙支持式导板下即刻种植修复前牙单牙缺失的效果及对美学指数的影响。方法:选取本院2020年10月至2022年10月期间收治的68例前牙单牙缺失患者作为研究对象,随机分为观察组与对照组,各34例。观察组在牙支持式导板下行即刻种植修复,对照组在常规导板下行即刻种植修复。术前与术后即刻行CBCT扫描测定术后精确度差异,术后3 m、术后6 m记录两组种植成功率,术后3 m、术后6 m采用红色美学指数(Pink ethetic score,PES)测定美学指数,术后3 m、术后6 m根据评分标准评价主观舒适度。结果:术后观察组根尖部、顶部、角度、深度的偏离值均较对照组显著减少(P<0.05)。两组术后3 m、术后6 m种植成功率比较,差异均无统计学意义(P>0.05)。观察组术后3 m、术后6 m PES评分、主观舒适度评分均较对照组显著提高(P<0.05)。结论:牙支持式3D打印导板能提高前牙单牙缺失患者即刻种植精确度,提升美学效果和舒适度。Objective:To investigate the effect of immediate implantation under the dental support guide in the restoration of anterior single tooth loss and its influence on aesthetic index.Methods:A total of 68 patients with anterior single tooth loss admitted to our hospital from October 2020 to October 2022 were selected as research objects and randomly divided into the observation group and the control group,with 34 cases in each group.The observation group underwent immediate implant repair under the dental support guide,while the control group underwent immediate implant repair under the conventional guide.The difference of postoperative accuracy was measured by CBCT scanning before and immediately after surgery,and the success rate of implantation was recorded at 3 months and 6 months after surgery.Pink ethetic score(PES)was used to measure aesthetic index at 3 months and 6 months after surgery,and subjective comfort level was evaluated according to the scoring criteria at 3 months and 6 months after surgery.Results:The deviation values of root apex,apex,Angle and depth in the observation group were significantly reduced compared with the control group(P<0.05).There was no significant difference in the success rate of implantation at 3 months and 6 months after surgery between the two groups(P>0.05).The PES scores of 3 months and 6 months and subjective comfort scores of the observation group were significantly higher than those of the control group(P<0.05).Conclusion:Dental support 3D printing guide can improve the accuracy of immediate implantation,aesthetic effect and comfort of patients with anterior single tooth loss.
