摘　　要：目的临床研究上下颌活动／固定矫治器的适配矫治生长发育期严重的Ⅲ类骨性反殆。方法共16名10～14岁以上颌后缩为主要表现的Ⅲ类骨性反殆患者，分为两组，一组佩戴上颌活动殆垫式的前牵矫治器的患者，下颌用固定矫治器；另一组上颌应用支架式快速扩弓加前牵的患者，下颌采用附有拉钩和殆垫的活动矫治器，每位患者均在治疗前和治疗后拍摄头颅侧位定位片和全口曲面断层片。结果16名患者经过治疗，不论从外形侧貌还是口内咬殆关系均基本达到正常。Ⅲ类咬合关系达到Ⅰ类咬合关系。SNA，ANB，1—1，IMPA和覆盖关系治疗前后差异显著，而SND，FMA，FMIA和覆胎治疗前后无显著差异性。结论上下颌活动／固定矫治器的适配，既能？肖除咬合干扰又能连续实施上颌骨矫形治疗，是一种临床有效的矫治骨性Ⅲ类反殆的好方法。Objective To investigate the clinical results using removable/fixed appliances in upper and lower jaws for treatment of skeletal Class Ⅲ crossbite. Methods Totally 16 skeletal Class Ⅲ cases, aged 10 - 14 years old with prominent retruded maxilla, were selected. Some cases were removable appliances in upper jaw and fixed appliances in lower jaw. The other cases used fixed appliances in upper jaw, such as screw expansion and hooks for protraction and removable apphances with hooks and ecclusa/ pads in lower jaw. Celphalogram-Panoramic radiographs were taken for each case before and after treatment. Results All eases have shown basic changes in profile and occlusion relationship to the normal condition. After treatment,SNA,ANB, 1.- 1, IMPA and overjet were increased and the significant differences were found（ P 〈 0.01 ）, while SND, FMA, FMIA and overbite showed no significant differences. Conclusion This method can not only remove ecclusal interference but also carry out protraction eontinously. It is demonstrated in clinical practice that this therapy for treatment of skeletal Class Ⅲ crosshite is a good way.
