摘　　要：目的探讨早期骨性下颌后缩双期矫治的疗效和规律。方法临床选择早期骨性下颌后缩的患者23例,其中男10例,女13例,年龄9～15岁(平均12.6岁),均处在生长发育高峰前期或高峰期。先期用方丝弓矫治器大体排齐上下牙弓,尔后装配Forsus下颌前移器,每侧力值设计为300g-500g。在导下颌成功的基础上,进一步匹配上下牙弓宽度和上下牙弓矢状关系,并对好上下牙齿咬合关系。结果在导下颌向前的23例骨性下颌后缩患者,下颌显著前移,面型协调美观,咬合关系均由Ⅱ类改变为Ⅰ类咬合关系,达到了满意的临床疗效。结论早期骨性下颌后缩的患者,通过固定式功能矫治器和固定矫治器进行双期矫治,均能达到良好疗效。Objective To evaluate the results of two-phase treatment for skeletal mandibular retrusion. Methods Twenty-three skeletal mandibular retrusion cases were chosen for this clinical study. All of the cases were in pre-puberty or puberty stages. Upper and lower dentitions were first aligned, and then Forsus appliance was fixed. The value of force of 300-500 grams was loaded in each side. The upper and lower arches and relationship were further accordinated and adjusted. Results Good profile and remarkable advancement of the mandible were obtained in all of these cases. Class Ⅱ occlusions were changed to Class Ⅰ relationship. SNB and ANB angles were changed from 74. 27 ± 1.98 and 7. 31 ±0. 86 to 78. 89 ± 2. 23 and 3.68 ± 0. 95 respectively. Conclusion Early skeletal mandibular retrusion can be treated by fixed functional appliance and Edgewise appliance in two-phase manner with good results.
