Abstract:
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:①Bionator appliances can hardly restrain the maxillary growth. ②Bionator appliances can promote the mandibular ramus and body growth and improve the soft tissue profile. ③Bionator 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. Conclusion:In Class II division 1 malocclusion treatment, Bionator appliances can obtain satisfactory effects.
