Abstract

Objectives: To investigate the changes made by orthodontists to the initial digital treatment plan (DTP) regarding the Invisalign appliance provided by Align Technology until acceptance of the plan by the orthodontist.

Materials and methods: The DTPs of subjects who underwent treatment with the Invisalign appliance and satisfied inclusion criteria were assessed to determine the number of DTPs and changes regarding prescription of aligners, composite resin (CR) attachments, and interproximal reduction (IPR) between the initial DTP and the accepted plan. Statistical analyses were calculated via GraphPad Prism 9.0 (GraphPad Software Inc., La Jolla, Calif).

Results: Most of the 431 subjects who satisfied inclusion/exclusion criteria were female (72.85%). More DTPs were required for subjects who had orthodontic extractions (median [interquartile range; IQR]: 4 [3, 5]) compared with those who did not (median [IQR]: 3 [2, 4], P < .0001). The median (IQR) overall number of aligners prescribed in the accepted DTP (30 [20, 39]) was greater than the initial DTP (30 [22,41], P < .001). The number of teeth used for CR attachments increased from the initial to the accepted DTP (P < .001). More CR attachments were observed in extraction treatment DTPs with a prescribed 2-week aligner change protocol compared with nonextraction treatment (P < .0001). The number of contact points with prescribed IPR increased between initial and accepted DTPs (P < .0001).

Conclusions: Significant changes regarding DTP protocols were observed between the initial and accepted DTPs and between nonextraction and extraction-based CAT.

Invisalign矫治器的治疗计划方案：一项探索性调查。

目的：调查正畸医生对Align Technology提供的Invisalign矫治器的初始数字治疗计划（DTP）所做的更改，直到该计划被正畸医生接受。材料和方法：对接受Invisalign矫治器治疗并符合纳入标准的受试者的DTP进行评估，以确定DTP的数量以及初始DTP和接受计划之间关于矫正器处方、复合树脂（CR）附件和邻间复位（IPR）的变化。通过GraphPad Prism 9.0（GraphPad Software股份有限公司，加利福尼亚州拉霍亚）计算统计分析。结果：431名符合纳入/排除标准的受试者中，大多数为女性（72.85%）。与未接受正畸矫正的受试人相比，接受正畸矫正（中位[四分位间距；IQR]：4[3，5]）需要更多的DTP（中位[IQR]：3[2，4]，P<.0001）（IQR）接受的DTP中规定的矫正器总数（30[20,39]）大于初始DTP（30[22，41]，P<.001）。用于CR附件的牙齿数量从初始DTP增加到接受DTP（P<.001在初始和接受的DTP之间，具有规定IPR的接触点数量增加（P<.0001）。结论：在初始和认可的DTP以及在非牵引和基于提取的CAT之间，观察到DTP协议的显著变化。
