| 摘 要： | 目的 采用McNamara分析法评价前方牵引对替牙列晚期Ⅲ类骨性错(牙合)的治疗效果.方法 选择20例替牙列晚期骨性反(牙合)患者(其中男11例,女9例),用面罩前方牵引治疗,治疗前后拍摄头颅侧位X线片,采用McNamara分析法用t检验进行比较分析.结果 治疗后矢状方向上有效上颌长度,上颌突度,上切牙突距增大;垂直方向上下前面高增大.结论 前方牵引能够改善Ⅲ类骨性错(牙合)的矢状关系,有利于错(牙合)的纠正.

| Abstract: | Objective To evaluate the effect of face-mash in treating skeletal crossbite on late mixture dentition by McNamara analysis.Methods Twenty late mixture dentition patients with skeletal crossbite treated by face-mash(male 11 and female 9) was selected,the cephalometric values before and after treatment were evaluated through McNamara analysis by t test.Results Maxillary length,maxillary protrusion,maxillary incisor protrusion increased through the treatment in anteroposterior relationship,and the lower anterior face height increased.Conclusion Face-mash can effectively improve the relationship of maxilla and mandible. |
