摘要
目的:研究Bionator矫治器治疗安氏Ⅱ类1分类下颌后缩骨性错的效果。方法:对12例患儿矫治前后软硬组织变化行X线头影测量分析。结果:①Bionator矫治器对上颌骨生长无明显的抑制作用;②使用Bionator矫治器可使下颌体及下颌升支长度明显增长,使下颌生长方向有利于软硬组织侧貌面型的改善;③Bionator矫治器可减少安氏Ⅱ类1分类骨性错患者的上前牙唇向倾斜,上下前后牙槽高度均增加。结论:Bionator矫治器对安氏II类1分类下颌后缩的骨性错有较好的治疗效果。
Objective：To study the treatment effects of 12 cases of Class Ⅱ division 1 malocclusion using Bionator appliances. Methods： 12 cases of Class II division 1 malocclusion were selected and treated with Bionator appliances. The changes of teeth, skeletal and facial appearance were analyzed by cephalometry before and after the treatment of Bionator appliances. Results：（1）Bionator appliances can hardly restrain the maxillary growth. （2）Bionator appliances can promote the mandibular ramus and body growth and improve the soft tissue profile. （3）Bionator appliances can reduce the labial inclination of upper incisors of Class Ⅱ division 1 malocclusion and can increase the height of dental alveolar of upper and lower jaw. Condusion： In Class Ⅱ division 1 malocclusion treatment, Bionator appliances can obtain satisfactory effects.
