Abstract:
Objective: To evaluate the effects of fixed inclined bite plate on jaw bone and dentition in juveniles with Class Ⅱ division 1 malocclusion.Methods: Eighteen patients(10 male and 8 female aged 11.5～13.8 years old) were treated with fixed inclined bite plate for bite-opening, twelve patients(6 male and 6 female) were involved as the control. Cephalograms were taken before and after the treatment.Results: After treatment ANB was significantly reduced and mandibular development was improved; AFH and PFH were significantly increased; the first molar in mandible was siginificantly elongated.Conclusion: Fixed inclined bite plate is effective in the improvement of sagittal skeletal relationship and in the orthodontic treatment in the juveniles with Class Ⅱ division 1 malocclusion.
