Two young patients, one female and one male, with asymmetric occlusal deviation and extreme Angle Class II division 1 malocclusions were treated with the Herbst appliance after cessation of endochondral growth (union of the radius epiphysis). During treatment, computer tomographic (CT) scanning and orthopantomograms of the temporomandibular joints (TMJs) revealed, as a result of bone modelling, asymmetrical new bone formation as a double contour on the distocranial part of the condyles. The treatment results were followed for more than 2 years and the new bone was found to be stable.
两名年轻患者，一女一男，均有不对称咬合偏差和严重安氏II类1分类错牙合，在软骨内生长停止（桡骨骨骺联合）后采用Herbst矫治器进行治疗。治疗期间，颞下颌关节（TMJ）的计算机断层扫描（CT）和曲面断层片显示，由于骨塑形，髁突远颅部出现不对称的新骨形成，表现为双重轮廓。对治疗结果进行了两年多的随访，发现新骨稳定。
