摘要： 目的 研究乳牙及替牙期反牙合经FR-Ⅲ矫治后牙合颌面的改变。方法 选择乳牙期及替牙期反牙合患者64例,全部采用FR-Ⅲ治疗,对治疗前后的牙牙合模型、薛氏位关节片及头颅定位侧位片进行测量分析,研究牙合颌面长、宽、高的改变情况。结果 上下颌牙弓宽度治疗前后无明显改变;上颌长度及突度增大,上切牙唇倾;下颌髁突后退至正常位,上下颌基骨关系明显改善;下切牙舌倾及颏角变小更趋严重;下面高及后面高增加。结论 FR-Ⅲ矫治器可重新调整口颌系统的肌功能,促进牙弓和颌骨的正常发育。

Abstract: Objective To study the changes of the dental occlusion and the maxillofacial region after treatment with FR-Ⅲfor crossbite in children in deciduous and mixed dentition phases. Methods Sixty-four children with crossbite in deciduous and mixed dentition phases were included in this study. Tooth models and Schuller’s position and lateral head X-rays were measured before and after treatment with FR-Ⅲto study the changes in the three-dimensional structures of the dental occlusion and maxillofacial region. Result The width of dental arch exhibited little changes after the treatment whereas the length of the maxillary dental arch was increased. The upper incisors grew in labial inclination and the condyle withdrew to its natural position. The relationship of maxillary and mandibular base bone was obviously improved after the treatment, which also promoted the lingual inclination of the lower incisiors and the decrease of the genial angle. The lower and posterior facial height was increased. Conclusion FR-Ⅲ readjusts the muscle function of oral and maxillofacial system and promotes normal development of the dental arch and jaw.
