在这项研究中，比较了两种口腔外矫形器的临床效果。在这项调查中使用了60个个体的侧位脑电图。研究组随机分为对照组、下颌头套组和下颌帽组。研究组的研究对象选自III类、低角度或垂直生长正常的个体。总观察期1年。结果表明，两种矫治器在骨骼上均有效，但两者之间存在一定差异。研究结果如下：下巴帽治疗抑制了上脸的发育，有效地控制了垂直尺寸以及下颌骨的后定位。下颌头套抑制了下颌骨的生长和发育，显示出下前面部高度的增加，并且发现了显着的下磨牙远端。
In this study, the clinical effects of two extra-oral orthopaedic appliances were compared cephalometrically. Lateral cephalograms of 60 individuals were used in this investigation. The study group was randomly divided into three parts as a) control, b) mandibular headgear and c) chin-cap groups. The subjects of the study group were selected among Class III, low angle or vertically normally growing individuals. The total observation period was one year. Results showed that both appliances were effective skeletally, but there were some differences between them. The results are as follows; chin-cap therapy led to an inhibition in the development of the upper face and an effective control of the vertical dimension in addition to the posterior positioning of the mandible. Mandibular headgear inhibited general growth and development of the mandible and showed an increase in lower anterior face height and also, a significant lower molar distalization was found.
