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.

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。

Objective To study the labiomental soft-tissues position of mormal permanent teeth occlusion in Yunnan province.Methods Eighty persons were measured on 9 items.The items including Sn、UL、LL、Si、Pos、UI、Li relative to a vertical reference line(VRL)through sella and nasolabial angle and labiomental angle.Results The standard values of labionmental soft-tissue position of young people with normal occlusion were obtained.There were significantly different in Sn-VRL、UL-VRL、LL-VRL(significant at the 0.01 level)、Si-VRL、Pos-VRL、UI-VRL(significant...

Objective To study the labiomental soft-tissues position of mormal permanent teeth occlusion in Yunnan province.Methods Eighty persons were measured on 9 items.The items including Sn、UL、LL、Si、Pos、UI、Li relative to a vertical reference line(VRL)through sella and nasolabial angle and labiomental angle.Results The standard values of labionmental soft-tissue position of young people with normal occlusion were obtained.There were significantly different in Sn-VRL、UL-VRL、LL-VRL(significant at the 0.01 level)、Si-VRL、Pos-VRL、UI-VRL(significant at the 0.05 level)between men and women.but not in nasolabial angle、labiomental angle and Li-VRL.There were significant correlations at the 0.01 level(2-tailed)in indication of Sn、UL、LL、Si、Pos、UI、Li.Nasolabial of men did not have correlation with any other items except negative correlation between labiomental and any other items.Conclusion There was variance in the feature of soft tissue profile from different sex.It is significant to establish the cephalometric mean of labiomental soft-tissue of normal occlusion in each region and nationality.Further studies will focus on the different of labiomental soft-tissue of normal occlusion among different regions.

目的 研究云南省正常牙合青年唇颏软组织位置及相关关系 ,以供临床参考。方法 通过对昆明市 80名侧貌美观的正常牙合青年 ,拍摄X线头颅定位片进行分析 ,采用修正FH平面 (CFH) ,通过S点作垂直于CFH的一条线为垂直参考面 (VRL)进行测量。结果 结果发现鼻唇角、唇颏角男女无差异 ,下切牙切缘到VRL的距离男女也无差异。鼻下点、上唇突点、下唇突点线距测量男女性别差异具有高度显著性 (P <0 .0 1)。颏唇沟、软组织颏前点及上中切牙切缘线距测量男女性别差异显著 (P <0 .0 5 )。无论男女性别 ,Sn、UL、LL、Si、Pos、UI、LI间线距测量不相关的概率几乎为 0 ,有明显的线性关系 ,而男性鼻唇角除与UL、LL、Pos存在负相关关系 (P <0 .0 5水平 )外 ,与其他指标无相关关系 ,唇颏角与其他指标间无相关关系。结论 建立了云南省正常牙合唇颏软组织CFH法测量的标准值。云南省正常牙合人上下唇及颏部测量值与国内其他地区比较具有显著性差异 ,表现出南方人较凸的面型。
