No-compliance orthodontic treatment has recently become very popular. Unlike removable appliances requiring patient compliance, the Herbst appliance is a widely used fixed functional bite-jumping device generating predictable results in the treatment of skeletal class II malocclusions. The main problem associated with tooth-borne bite-jumping appliances is the generation of unavoidable dental movements, especially proclination of lower incisors, in addition to the skeletal effect. These dento-alveolar compensations can, when uncontrolled, compromise treatment results. This article describes two cases managed with a new treatment protocol based on the association of a modified Herbst appliance and temporary skeletal anchorage devices (TSADs) for efficient treatment of skeletal class II malocclusions.
非依从性正畸治疗近来变得非常流行。与需要患者配合的可摘矫治器不同,Herbst矫治器是一种广泛使用的固定功能性咬合前移装置,在治疗骨性II类错颌畸形方面能产生可预测的效果。与牙支持式咬合前移矫治器相关的主要问题是,除了骨骼效应外,还会产生不可避免的牙齿移动,尤其是下前牙的前倾。如果不加以控制,这些牙牙槽代偿可能会影响治疗效果。本文介绍了两例采用新治疗方案进行治疗的病例,该方案基于改良的Herbst矫治器与临时骨锚固装置(TSADs)联合使用,以有效治疗骨性II类错颌畸形。
