Abstract

Objective

The objective of this prospective study was to assess possible changes in the position and shape of the temporomandibular joint (TMJ) articular disc in patients treated with two protocols of rapid maxillary expansion (RME) and face mask (FM) therapy.

Methods

A sample of 88 patients with Class III or Class III subdivision malocclusions, aged between 6 and 13 years, were consecutively selected and divided into three groups (G): G1-34 patients were treated with RME, followed by FM therapy; G2-34 patients were treated using RME according to modified alternate rapid maxillary expansion and constriction (ALT-RAMEC) protocol, followed by FM therapy. These treated groups were randomly (1:1 allocation ratio) distributed according to the two treatment protocols. G3 – Control Group – 20 untreated patients were followed. Magnetic resonance imaging (MRI) TMJs were obtained before (T1) and after (T2) a treatment period or follow-up. McNemar test, Fisher's exact test and intra- and inter-observer concordance (K) were performed (p ≤ .05).

Results

There were no statistically significant differences in the baseline cephalometric variables at T1 between the groups. There were statistically significant differences between the groups (p < .001) in relation to the disc shape in T1, since G1 (8 TMJs −11.76%) presented higher occurrences of altered forms in comparison with G2 (no changes). No significant differences were observed in disc position CM and OM (G1 – p > .999; G2 – p = .063; G3 – p = .500) and shape (G1 – p > 0.999; G2 – p = .250; G3 – not calculable), between T1 × T2, in any of the groups studied.

Conclusion

The two treatment protocols did not have adverse effects on the position and shape of the TMJ disc, in a short-term evaluation.

接受快速上颌扩张和面罩治疗两种方案的患者的颞下颌关节盘位置和形状：随机临床试验。

研究目的这项前瞻性研究的目的是评估接受快速上颌扩弓（RME）和面罩（FM）两种治疗方案的患者颞下颌关节（TMJ）关节盘的位置和形状可能发生的变化：连续选取88名年龄在6至13岁之间的Ⅲ类或Ⅲ类下颌畸形患者，将其分为三组（G组）：G1-34组患者接受RME治疗，然后接受调频治疗；G2-34组患者根据改良的上颌快速扩张和收缩交替方案（ALT-RAMEC）接受RME治疗，然后接受调频治疗。这些治疗组按照两种治疗方案随机分配（分配比例为 1:1）。G3 - 对照组 - 20 名未经治疗的患者。在治疗前（T1）和治疗后（T2）或随访期间采集颞下颌关节磁共振成像（MRI）。进行了 McNemar 检验、费雪精确检验以及观察者内部和观察者之间的一致性检验（K）（P ≤ .05）：结果：两组在 T1 期的头颅测量基线变量无明显统计学差异。在研究的任何一组中，T1 × T2 之间的组间差异（p .999；G2 - p = .063；G3 - p = .500）和形状差异（G1 - p > 0.999；G2 - p = .250；G3 - 无法计算）均有统计学意义：结论：在短期评估中，两种治疗方案对颞下颌关节盘的位置和形状没有不良影响。

期刊介绍： Orthodontics & Craniofacial Research - Genes, Growth and Development is published to serve its readers as an international forum for the presentation and critical discussion of issues pertinent to the advancement of the specialty of orthodontics and the evidence-based knowledge of craniofacial growth and development. This forum is based on scientifically supported information, but also includes minority and conflicting opinions. The objective of the journal is to facilitate effective communication between the research community and practicing clinicians. Original papers of high scientific quality that report the findings of clinical trials, clinical epidemiology, and novel therapeutic or diagnostic approaches are appropriate submissions. Similarly, we welcome papers in genetics, developmental biology, syndromology, surgery, speech and hearing, and other biomedical disciplines related to clinical orthodontics and normal and abnormal craniofacial growth and development. In addition to original and basic research, the journal publishes concise reviews, case reports of substantial value, invited essays, letters, and announcements. The journal is published quarterly. The review of submitted papers will be coordinated by the editor and members of the editorial board. It is policy to review manuscripts within 3 to 4 weeks of receipt and to publish within 3 to 6 months of acceptance.
