摘要
目的:研究山东省正常儿童、青少年的AF-BF距及AXB角。方法:对72例山东省正常者及51例恒牙早期正常者拍摄头颅定位侧位片,测量其AF-BF距及AXB角。结果:得出了山东省正常替牙期组及恒牙早期组的AF-BF距及AXB角的正常值范围。结论:AF-BF距及AXB角是反映上下颌骨间的前后位置关系;在某些情况下可代替ANB角及"wits"分析法。
Objective：To study AF-BF distance and AXB angle pf normal occlusion kids and adolecence in Shandong area. Methods：Seventy-two children in mixed dentition and fifty-one children in early permanent-dentition were included, each was taken a LAT film to measure AF-BF distance and AXB angle. Results：This study offered a range of normal value of AF-BF distance and AXB angle both mixed-dentition and early permanent dentition. Conclusion： AF-BF distance and AXB angle can assess anteroposterior jaw relation;AF-BF distance and AXB angle can replace ANB and wits nalysis.
