The acceptability and preference for clear aligner therapy (CAT) has been increasing among orthodontists, but there is still a lack of consensus regarding CAT best practices. Consequently, this study aimed to investigate CAT practices among orthodontists practicing in Canada.
The survey was conducted among orthodontists practicing in Canada using a modified previously published survey. Sixty orthodontists participated (6.1% response rate). It consisted of 11 sections with open and closed questions related to demographic information and particularities about using or not using CAT. The survey responses were exported from REDCap to a Microsoft Excel (Microsoft, Redmond, Wash) spreadsheet, then statistically analyzed using SPSS software (SPSS for Windows, version 21.0; IBM Inc., Armonk, NY, USA). The comments were categorized under themes and subthemes. Data were organized in descriptive statistics, expressing frequencies and percentages.
Almost 30% of the orthodontist's annual caseload was treated with CAT, most frequently prescribed to adult patients. Case complexity and patient cooperation were the factors that most influenced the decision to prescribe CAT. Almost half of orthodontists reported sometimes combining CAT with adjunctive fixed appliances.
Most orthodontists prescribe CAT, and its use is based on the malocclusion's complexity. Orthodontists who do not prescribe CAT believe that fixed appliance therapy has superior treatment outcomes.
Clear aligner therapy（透明牙套矫正治疗，简称 CAT）在正畸医生中的接受度和偏好度越来越高，但关于 CAT 的最佳实践仍然缺乏共识。因此，本研究旨在调查加拿大执业正畸医生的 CAT 实践情况。
本研究采用改良的先前发表的调查问卷，对加拿大的正畸医生进行了调查。共有 60 名正畸医生参与（回应率为 6.1%）。调查问卷包括 11 个部分，其中包含与人口统计学信息和使用或不使用 CAT 的特殊性相关的开放性和封闭性问题。调查回复从 REDCap 导出到 Microsoft Excel（Microsoft，Redmond，Wash）电子表格中，然后使用 SPSS 软件（Windows 版 SPSS 21.0；IBM Inc.，Armonk，NY，USA）进行统计分析。评论被归类为主题和子主题。数据以描述性统计表示，表达频率和百分比。
近 30%的正畸医生的年度病例量采用 CAT 治疗，最常用于成年患者。病例复杂性和患者合作是影响处方 CAT 的主要因素。近一半的正畸医生报告有时将 CAT 与附加固定矫治器联合使用。
大多数正畸医生都会开 CAT 治疗，其使用基于错颌畸形的复杂性。不开 CAT 的正畸医生认为固定矫治器治疗的效果更好。
