数字化3D打印种植导板对前牙区种植体的精确度及美学效果的影响分析

Analysis of the Influence of Digital 3D-printing Implant Guide on the accuracy and Aesthetic Effect of Anterior Dental Implants

目的:探讨数字化3D打印种植导板对前牙区种植体的精确度及其美观度影响。方法:本研究以2020年10月-2021年5月在笔者医院行牙齿种植术的88例患者作为研究对象,按照随机分组原则,将患者分为观察组和对照组,每组44例。观察组患者采取光固化快速成型技术3D打印制定的牙种植导板行牙种植手术,而对照组患者采取常规导板种植体植入手术。比较两组患者前牙区种植体的精确度、治疗效果、美观状况、牙周健康情况及外观满意率之间的差异。结果:观察组患者的顶端偏差值、底端偏差值、垂直向距离偏差值、角度偏差显著低于对照组(P<0.05);观察组有效率(90.91%)和对照组(88.64%)比较,差异无统计学意义(P>0.05)。治疗后,两组患者红色美学指数与白色美学指数均显著提升,牙龈乳头指数得分明显下降,且观察组改变幅度高于对照组(P<0.05)。治疗后,两组患者菌斑指数、牙周袋探诊深度、龈沟出血指数以及牙龈指数均改善,且观察组患者菌斑指数、牙周袋探诊深度、龈沟出血指数均高于对照组,而牙龈指数低于对照组(P<0.05)。观察组外观满意率(93.18%)高于对照组(72.73%),差异有统计学意义(P<0.5)。结论:前牙区种植体修复过程中采取数字化3D打印种植导板进行治疗,治疗后的精确度及外观满意率均显著提升,患者的美观性、牙周健康状况均明显改善,可临床推广应用。

Objective To study the accuracy of digital 3D printing implant-guided anterior tooth implantation,and to analyze its aesthetic impact.Methods A prospective study was conducted on 88 patients who underwent tooth implantation in the author's hospital from October 2020 to May 2021.Patients were randomly classifi ed into two groups,each with 44 cases.Observation group received the implant placement aided with templates via 3D printing technology based on light-curing rapid prototyping technology,while control group received conventional implant placement with normal templates.Then comparison was conducted between two groups in terms of implant accuracy,treatment effect,aesthetic score,periodontal health and appearance satisfaction rate.Results The deviation values of implant top,bottom and vertical distance of observation group were notably smaller than those of control group(P<0.05).The efficacy rate was 90.91%in observation group,which had no statistical difference with 88.64%in control group(P>0.05).After treatment,an increase in pink esthetic score(PES)and white esthetic score(WES)as well as a decrease in papilla index scores(PIS)were detected in both groups(P<0.05),and both changes were more remarkable in observation group than in control group(P<0.05).After treatment,the plaque index(PLI),sulcus bleeding index(SBI),probing depth(PD)and gingival index(GI)of the two groups were signifi cantly improved,and PLI、SBI、PD of the observation group were signifi cantly higher than those of the control group,while the GI was signifi cantly lower than that of the control group(P<0.05).The appearance satisfaction rate was 93.18%in observation group,which was higher than 72.73%in control group,with statistical diff erence(P<0.05).Conclusion Application of digital 3D-printied implant templates-guided anterior tooth implantation achieves good accuracy and appearance satisfaction rate,which can effectively can effectively improve the aesthetic effect and periodontal health,which is worthy of recommendation.
