The causal therapy of skeletal Class II anomaly consists of the changes of the jaws' relationships to each other during the growth of the craniofacial complex. A plenty of orthodontic appliances are employed, the effectiveness of which remain debatable. This paper attempts to compare the three main orthodontic appliances used in our clinic: activator, headgear and combined headgear activator. Patients with a skeletal Class II anomaly at the beginning of treatment were studied with two different types of cephalometric analysis. The lateral X-ray head films were carried out directly before and after treatment. In this study the growth pattern of the patients' craniofacial complex has been seriously taken into consideration. Following conclusions are to be taken: The initial skeletal Class II anomaly as well as the orthodontic appliances have to be differentially evaluated by the treatment planning. The isolated changes are often not great, but taken as a whole, they attain to correct the existing anomaly. The annual rates of the jaws' length depends not only on the age, the sex and the duration of orthodontic treatment, but also on the growth pattern of the craniofacial complex and the particularities of treatment methods. In order to achieve the therapeutic aims all these factors are to be considered for the treatment planning.
骨性安氏II类错畸形的病因治疗包括在颅面复合体生长过程中颌骨相互关系的改变。人们使用了大量正畸矫治器，但其效果仍存在争议。本文试图比较我们诊所使用的三种主要正畸矫治器：肌激动器、头帽和联合头帽肌激动器。对治疗开始时患有骨性安氏II类错畸形的患者进行了两种不同类型的头影测量分析。在治疗前后直接拍摄头颅侧位X线片。在本研究中，充分考虑了患者颅面复合体的生长模式。得出以下结论：对于治疗计划，必须对初始的骨性安氏II类错畸形以及正畸矫治器进行差异化评估。孤立的变化通常不大，但总体而言，它们能够矫正现有的错畸形。颌骨长度的年增长率不仅取决于年龄、性别和正畸治疗的持续时间，还取决于颅面复合体的生长模式和治疗方法的特殊性。为了实现治疗目标，在制定治疗计划时必须考虑所有这些因素。
