摘　　要：功能性矫治器发展至今已数 10年 ,虽然其机制仍有争议 ,但临床效果显著 ,所以仍广泛应用于临床。可通过头影测量观察疗效。本文介绍的是以合平面OL及通过蝶鞍点s的垂直平面OLp为参考平面的点、线距的测量方法。测量点主要是颌骨及牙齿 ,包括上下颌基骨、切牙、第 1恒磨牙及髁状突的位置。计算各测量点到OLp垂直距离的变化即位置的变化。进一步通过一些百分比的计算可以得出在覆盖及磨牙关系的改善中 ,上、下颌骨及牙齿的变化所占的比例。The functional correction device developed more than decades with dispute of its mechanism had reached satisfied effect and used widely. Its curative effect could be observed by skull detection. This paper had introduced the detection method as reference of point and line of mandible surface OL and s point vertical Olp and calculate the position change. Further to assess the relation of percentage improvement of cover and molar and the ratio of mandibular and teeth relation. This paper suggested this method could be used in clinc.
