OBJECTIVE
To evaluate the effects of modified Forsus appliance in the treatment of Class II mandibular retrusion.
METHODS
18 children with mandibular retrusion were selected and treated with modified Forsus appliance. Cephalometric radiographs were taken and analyzed at pre-treatment and post-treatment. Students' t-test was used to determine if there were significant differences between pre-treatment and post-treatment.
RESULTS
After 6-8 months of therapy, profiles were obviously improved. B moved forward (2.9+/-3.1) mm. ANB decreased (2.5+/-1.2) degrees. The overjet decreased (5.0+2.8) mm. The molar relationship was corrected to Class I from Class II. SN-OL increased (4.3+2.2) degrees. There was significant difference between pre-treatment and post-treatment.
CONCLUSION
Combined with straight wire appliance, modified Forsus appliance can effectively stimulate the mandibular growth, balance the jaw relationship, and correct mandibular retrusion.
目的
评估改良 Forsus 矫治器治疗安氏 II 类下颌后缩的效果。
方法
选取 18 例下颌后缩患儿，采用改良 Forsus 矫治器进行治疗。治疗前、后拍摄头颅定位侧位片并进行分析。采用学生 t 检验确定治疗前、后是否存在显著差异。
结果
经过 6 - 8 个月的治疗，面部侧貌明显改善。B 点前移（2.9±3.1）mm。ANB 角减小（2.5±1.2）度。覆盖减小（5.0 + 2.8）mm。磨牙关系从 II 类纠正为 I 类。SN - OL 增加（4.3±2.2）度。治疗前、后差异有统计学意义。
结论
改良 Forsus 矫治器联合直丝弓矫治器能有效刺激下颌生长，平衡颌关系，纠正下颌后缩。
