隐形矫正联合种植修复治疗错[牙合]畸形伴牙列缺损患者的临床疗效评价

A Clinical Effect Evaluation of Digital Invisible Orthodontic Combined with Implant Prosthodontics in the Treatment of Malocclusion with Dentition Defect

目的:探讨数字化隐形矫正和传统固定正畸联合种植修复治疗在前牙美学区应用中的疗效差异。方法:收集2018年6月-2020年6月在合肥市口腔医院就诊的符合条件的患者40例,按照随机数字表法分为两组。实验组采用数字化无托槽隐形矫治器联合种植修复治疗,对照组为传统固定正畸联合种植修复治疗。观察两组病例的矫正时间、牙根平行度、龈沟出血指数及红白美学分值差异。结果:矫正结束后,实验组矫正时间短于对照组(P<0.05);实验组牙根平行度优于对照组(P<0.05),差异均有统计学意义;实验组矫治中不同时间点龈沟出血指数(SBI)变化比较,差异有统计学意义(P<0.05),两组SBI变化比较差异无统计学意义(P>0.05);正畸联合种植修复治疗后,实验组红白美学分值中近中龈乳头、远中龈乳头、唇侧龈缘曲线、牙冠形态及牙冠外形轮廓五项指标优于对照组,差异有统计学意义(P<0.05),总分值比较差异无统计学意义(P>0.05)。结论:数字化隐形矫正联合种植修复能够正确引导治疗方案的制定,从而缩短正畸疗程,提高种植手术安全性,患者可获得理想的美学效果及更加完美的咬合功能。

Objective The thesis of this paper is to investigate the clinical effect differences between digital invisible orthodontics and traditional fixed orthodontics in orthodontic combined implant repair(treatment)on the aesthetic area of anterior teeth.Methods A total of 20 eligible patients admitted to Hefei Stomatological Hospital from June 2018 to June 2020 were collected and divided into two groups according to the random number table method.The experimental group received digital invisible orthodontic treatment combined with implantation,and the control group received traditional fi xed orthodontic treatment combined with implantation.The diff erences of correction time,root parallelism,sulcus bleeding index and red&white aesthetic score between the two groups were observed.Results After correction,the experimental group required less correction time while performed better root parallelism than the control group(P<0.05),with statistical significance.In the experimental group there was statistical signifi cance in SBI changes at diff erent time points during the treatment(P<0.05),but no statistical signifi cance in SBI changes between the two groups(P>0.05).Otherwise,the experimental group outperformed the control group in the fi ve indexes of the red&white aesthetic after orthodontic combined implantation(P<0.05),including the proximal and distal gingival papilla,labial gingival margin curve,crown shape and crown contour(P>0.05).The statistical significance was proven in variances in red&white aesthetic(P<0.05),while not in total score variance(P>0.05)between two groups.Conclusion Digital invisible orthodontics combined with implantation can simulate the treatment eff ect more precisely,guide the formulation of treatment plan more correctly,shorten the course of orthodontic treatment,accurately locate the implant position more accurately to improve the safety of implant surgery,and enable such patients to obtain ideal aesthetic eff ect and more perfect occlusion function.
