Abstract

Objective: The aim was to assess adult patients' weight changes during the initial phase of orthodontic treatment (OT) with clear aligner therapy (CAT) versus fixed bracket systems (FBS).

Methods: This pilot prospective cohort study included systemically-healthy adults who were treated with CAT or FBS. Participants with eating disorders and/or undergoing dietary programs were excluded. Weight was assessed using a calibrated digital scale at the start of OT (T1), 6-8 weeks (T2), and 12-16 weeks (T3) after starting OT. A questionnaire was used to record demographic variables, diet and exercise habits, self-reported compliance and discomfort during OT, and use of analgesics. Repeated measures analysis of variance was used to assess the association between treatment type (FBS versus CT) and time-period (T1, T2, T3) on participants' weight while adjusting for baseline covariates such as age, gender, height, and weight.

Results: Forty-two participants (CAT group: 22 and FBS group: 20) were analysed. In the CAT group, there was a slight initial mean weight gain of 0.2 Kg (~ 0.4 pounds) (T2-T1), and 0.8 Kg (~ 1.7 pounds) overall mean weight loss between T1 and T3. For the FBS group, there was a slight initial weight loss of 0.3 Kg (~ 0.7 pounds) (T2-T1) and no overall change between T1 and T3. Treatment type (CAT versus FBS) was not significantly associated with weight changes during the initial phase of OT.

Conclusions: There were no significant differences in the weight changes during the initial phase of OT with CAT compared with FBS.

Clinical relevance: Clear aligner therapy should not be advertised as a weight loss strategy.

使用透明矫治器与固定矫治器进行正畸治疗初期的体重变化：一项前瞻性队列试验研究。

目的目的是评估成年患者在使用透明矫治器（CAT）和固定托槽系统（FBS）进行正畸治疗（OT）初期的体重变化情况：这项试验性前瞻性队列研究包括接受透明矫治器治疗或固定托槽系统治疗的全身健康的成人。不包括患有饮食紊乱和/或正在接受饮食治疗的参与者。使用校准过的电子秤在开始 OT 时（T1）、开始 OT 后 6-8 周（T2）和 12-16 周（T3）对体重进行评估。调查问卷用于记录人口统计学变量、饮食和运动习惯、自我报告的依从性、OT 期间的不适感以及镇痛药的使用情况。在调整年龄、性别、身高和体重等基线协变量的同时，采用重复测量方差分析评估治疗类型（FBS 与 CT）和时间段（T1、T2、T3）对参与者体重的影响：对 42 名参与者（CAT 组 22 人，FBS 组 20 人）进行了分析。在 CAT 组中，初始平均体重略微增加了 0.2 千克（约 0.4 磅）（T2-T1），而在 T1 和 T3 之间，总体平均体重减少了 0.8 千克（约 1.7 磅）。至于 FBS 组，初始体重轻微下降了 0.3 千克（约 0.7 磅）（T2-T1），T1 至 T3 期间总体体重没有变化。治疗类型（CAT 与 FBS）与 OT 初始阶段的体重变化无明显关联：结论：与 FBS 相比，CAT 在 OT 初始阶段的体重变化没有明显差异：临床意义：不应将透明矫治器疗法宣传为一种减肥策略。

期刊介绍： The journal Clinical Oral Investigations is a multidisciplinary, international forum for publication of research from all fields of oral medicine. The journal publishes original scientific articles and invited reviews which provide up-to-date results of basic and clinical studies in oral and maxillofacial science and medicine. The aim is to clarify the relevance of new results to modern practice, for an international readership. Coverage includes maxillofacial and oral surgery, prosthetics and restorative dentistry, operative dentistry, endodontics, periodontology, orthodontics, dental materials science, clinical trials, epidemiology, pedodontics, oral implant, preventive dentistiry, oral pathology, oral basic sciences and more.
