摘　　要：目的　探讨用APDI评价颌骨矢状位置关系的可靠性。方法　随机选取 72张正畸患者治疗前X线头颅定位的侧位片 ,安氏Ⅱ类和Ⅲ类错牙合分别为 35张和 37张。以常规描图法 ,测得面角、AB平面角、腭平面角及APDI,并进行统计分析。结果　①AB平面角在安氏Ⅱ类错牙合组中男、女性别上有显著差异 ,而其他各测量指标均无性别上差异。②APDI在安氏Ⅱ类错牙合组中与AB平面角的女性组有相关性。③APDI在安氏Ⅱ类和Ⅲ类错牙合组中的均值分别为 (78.0 5 9± 4 .6 6 7)°和 (91.4 4 6± 5 .6 6 3)°。结论　用APDI评价上、下颌骨矢状位置关系在安氏Ⅲ类错牙合中可为有效的指标。Objective To assess the reliability of sagittal position relation between maxilla and mandible with APDI. Methods Used the lateral cephalometric radiographs of orthodontics ago as materials and selected the 72 X-Ray films with Angle Ⅱ,Ⅲ malocclusion. Traced and measured the angles of FH-PP, FH-Npog, AB-Npog and APDI. Results ①In Angel Ⅱ Malocclusion, AB-Npog angle showed statistical difference on sex (P<0.01)。②In girl′s Angle Ⅱ malocclusion, there was correlation between APDI and AB-Npog angle (γ=0.591). ③In Angle Ⅱ malocclusioin, APDI (78.059±4.667)°; In Angle Ⅲ malocclusion, APDI (91.446±5.663)°. Conclusion In Angle Ⅲ malocclusion, to reseach on sagittal relationship between maxillla and mandible with APDI which is the best reliably index.
