From a consecutive sample of 100 patients treated with the Herbst appliance after the peak of puberal growth, a boy was chosen to show the total effect of the Herbst treatment. Changes in the dentofacial morphology and the structure of the temporomandibular joints (TMJ) were followed by radiologic examinations and the function of the craniomandibular system was studied by clinical examinations, and electromyographic and bite-force recordings. Treatment resulted in marked dentoalveolar changes, an increase of mandibular length, ramus height, and gonion angle. Three months after insertion of the appliance CT-scanning and orthopantomograms of the TMJ revealed new bone formation as a double contour in the fossa articularis and on the posterior part of the condylar process as a result of adaptive bone remodelling. Function was affected by treatment, but was markedly restored at control.
从青春期生长高峰期后接受Herbst矫治器治疗的100例连续样本患者中，挑选出一名男孩以展示Herbst治疗的整体效果。通过放射学检查追踪牙颌面形态和颞下颌关节（TMJ）结构的变化，并通过临床检查、肌电图和咬合力记录研究颅下颌系统的功能。治疗导致明显的牙槽变化，下颌长度、升支高度和下颌角增加。矫治器植入三个月后，TMJ的CT扫描和曲面断层片显示，由于适应性骨重塑，关节窝和髁突后部出现了新骨形成，表现为双重轮廓。功能受到治疗的影响，但在复查时明显恢复。
