摘要

导言：上颌中切牙（MxCIs）的正确定位是微笑美学和正畸治疗成功的重要组成部分。本研究通过与 ClinCheck（Align Technology，加利福尼亚州圣何塞）的预测进行客观比较，调查了隐适美 SmartTrack 矫正器在实现 MxCIs 中切牙牙尖定位方面的功效：从澳大利亚矫正器研究数据库中选取了 87 名成年患者的 174 颗 MxCI 牙齿。所有患者在治疗前都有重叠的 MxCI 牙冠，并接受了隐适美智能跟踪矫治器的治疗。对治疗前的牙齿位置、使用 ClinCheck 软件进行的计划中牙根尖移动以及治疗后的牙齿位置进行了分析：结果：在计划的中侧根尖 MxCI 组中，计划的中侧根尖平均值和实现的中侧根尖平均值分别为 2.53°（标准误差 [SE]，0.29°）和 2.22°（标准误差，0.42°），表明矫正不足 0.31°（标准误差，0.38°）（P >0.05）。对于计划的远端根尖 MxCI 组，计划的远端根尖和实现的远端根尖的平均值分别为 2.09°（SE，0.22）和 0.39°（SE，0.36°），表明平均矫正不足 1.70°（SE，0.39°）（P 0.05）。1周或2周戴用计划与MxCIs达到中轴尖的疗效之间没有发现明显的关系（P>0.05）：结论：使用Invisalign SmartTrack矫治器治疗MxCIs时，牙间尖移动的总体准确率为53.3%。附着体的存在以及1周与2周佩戴计划的影响对MxCIs实现计划的中轴尖移动的效果没有明显影响。

Predictability of mesiodistal tip of maxillary central incisors in clear aligner therapy.

Introduction: Correct positioning of the maxillary central incisors (MxCIs) is a vital component of smile esthetics and the success of orthodontic treatment. This study investigated the efficacy of Invisalign SmartTrack aligners in achieving the mesiodistal tip of MxCIs, with an objective comparison to the ClinCheck (Align Technology, San Jose, Calif) prediction.

Methods: A total of 174 MxCI teeth from 87 adult patients were selected from the Australasian Aligner Research Database. All patients exhibited pretreatment overlapping MxCI crowns and were treated with Invisalign SmartTrack aligners. The pretreatment tooth position, the planned mesiodistal tip movement using the ClinCheck software, and the achieved posttreatment tooth position were analyzed.

Results: In the planned mesial root tip MxCI group, the mean planned and achieved mesial tips were 2.53° (standard error [SE], 0.29°) and 2.22° (SE, 0.42°), respectively, indicating an undercorrection of 0.31° (SE, 0.38°) (P >0.05). For the planned distal root tip MxCI group, the mean planned and achieved distal tips were 2.09° (SE, 0.22) and 0.39° (SE, 0.36°), respectively, indicating a mean undercorrection of 1.70° (SE, 0.39°) (P <0.001). There was no statistically significant association between the presence of attachments and the efficacy of the mesiodistal tip for MxCIs (P >0.05). No significant relationship was found (P >0.05) between the 1- or 2-week wear schedule and the efficacy of achieving the mesiodistal tip for MxCIs.

Conclusions: The overall percentage accuracy of mesiodistal tip movements for MxCIs when using Invisalign SmartTrack aligners was 53.3%. The presence of attachments and the influence of a 1- vs 2-week wear schedule were not found to have any significant influence on the efficacy of achieving planned mesiodistal tip movements for MxCIs.

期刊介绍： Published for more than 100 years, the American Journal of Orthodontics and Dentofacial Orthopedics remains the leading orthodontic resource. It is the official publication of the American Association of Orthodontists, its constituent societies, the American Board of Orthodontics, and the College of Diplomates of the American Board of Orthodontics. Each month its readers have access to original peer-reviewed articles that examine all phases of orthodontic treatment. Illustrated throughout, the publication includes tables, color photographs, and statistical data. Coverage includes successful diagnostic procedures, imaging techniques, bracket and archwire materials, extraction and impaction concerns, orthognathic surgery, TMJ disorders, removable appliances, and adult therapy.
