To compare 2 groups of mature patients treated with the Herbst appliance and present a new protocol based on tissue responses to enhance skeletal response.
Lateral cephalograms taken before and after treatment for 2 groups of patients--the first treated with the Herbst appliance with maximum jumping and the second with the Herbst appliance with stepwise advancement--were examined with conventional cephalometric analysis and the sagittal-occlusal analysis of Pancherz to assess the dental, skeletal, and soft tissue changes.
The mode of correction of the Class II malocclusion was through skeletal and dental changes. However, in the stepwise sample, the amount of correction due to skeletal changes was higher. In both groups, the soft tissue profile convexity was reduced significantly.
Herbst appliance therapy can be considered a modality for the correction of skeletal Class II malocclusions in mature patients and should be added to orthodontia's armamentarium.
比较两组使用Herbst矫治器治疗的成年患者，并基于组织反应提出一种新方案以增强骨骼反应。
对两组患者治疗前后拍摄的头颅侧位片——第一组采用最大跳跃式的Herbst矫治器治疗，第二组采用逐步前伸式的Herbst矫治器治疗——进行传统头影测量分析和潘彻兹矢状-咬合分析，以评估牙齿、骨骼和软组织的变化。
安氏II类错牙合的矫治方式是通过骨骼和牙齿的改变。然而，在逐步前伸组样本中，骨骼改变导致的矫治量更高。两组患者的软组织侧貌凸度均显著降低。
Herbst矫治器治疗可被视为成年患者骨骼性安氏II类错牙合的一种矫治方式，应纳入正畸治疗手段之中。
