摘　　要：目的应用McNamara分析法对安氏Ⅱ类1分类错畸形进行头影测量,探讨其对安氏Ⅱ类1分类错畸形诊断、治疗的意义。方法选择安氏Ⅱ类1分类错畸形患者60例,拍摄X线头颅定位侧位片,进行McNamara分析,得到7项相关指标。应用SPSS 17.0进行统计分析。结果①男性安氏Ⅱ类1分类错畸形患者有效上颌长度、上颌突距大于男性正常(P<0.05);②女性安氏Ⅱ类1分类错畸形患者有效上颌长度、下颌突距、上切牙突距均大于女性正常(P<0.05)。③男性拔牙患者上颌突距,上切牙突距及下切牙突距明显大于男性非拔牙患者(P<0.05)。④女性拔牙患者上颌突距明显大于女性非拔牙患者(P<0.05)。结论 McNamara分析法的部分数据对安氏Ⅱ类1分类错畸形的诊断及矫治设计有参考价值;男性患者上颌突距大于正常值的17.10%同时上下切牙突距分别大于正常值的54.03%和60.61%时可考虑拔牙。女性患者上颌突距大于正常值的36.71%时可考虑拔牙。Objective To discuss the signification of McNamara cephalometric analysis on diagnosis and treatment of Angle II division 1 malocclusion. Methods Sixty patients with Angle II division 1 malocclusion were taken the X- ray lateral cephalometric radiographs, related data were analyzed by using McNamara cephalometric analysis and SPSS17.0 package, in which 7 indexes were obtained. Results The effective maxillary length and the maxillary protrusion of male patients in Angle II division 1 were greater than normal male occlusion （P〈0.05）. The effective maxillary length, mandibular protrusion and upper incisor protrusion of female patients in Angle II division 1 were greater than normal female occlusion （P〈0.05）. Maxillary protrusion, upper incisor protrusion and lower incisor protrusion in male Angle II division 1 with extraction was greater than male patients without extraction （P〈0.05）. Maxillary protrusion in female an- gle II division I with extraction was greater than female patients without extraction （P〈0.05）. Conclusions The partial data of McNamara cephalometric analysis have reference signification on diagnosis and treatment of Angle II division 1 malocclusion. Exelcymosis is a good choice when maxillary protrusion exceeds the normal 17.10% and upper incisor protrusion exceeds the normal54. 03%, with lower incisor protrusion exceeding 60.61% for male, with maxillary protrusion exceeding 36. 71% for fFemale.
