Lundstrons基底理论(apical basetheooy)和毛燮均氏分类法,都强调了基骨(Basal bone arch)和牙弓形态的匹配,以及牙量和骨量的谐调。随着头影测量技术对正畸学的介入,临床正畸已从对错(牙合)性状的定性描述进入到定量分析的阶段。本文作为完成定量分析研究的一个部份拟就基骨、牙弓、牙量的相关性问题予以报道。并建立基骨、牙弓等自变推导牙量的多元回归方程,试图借此来选择适当的矫治方案。 一、资料来源 根据对上海市区和郊区二所中学,三所
Both the Lundstrons apical basetheooy and the Mao's Kyrgyz classifications emphasize the matching of the Basal bone arch to the dental arch, as well as the tuning of the tooth volume and bone mass. With the introduction of cephalometric techniques to orthodontics, clinical orthodontics has entered the quantitative analysis stage from the qualitative description of right and wrong occlusion (occlusion) traits. This article as part of a quantitative analysis to be completed on the basis of bone, dental arch, the amount of dental issues to be reported. And the establishment of the base bone, dental arch and other variables derived from the variable regression multiple regression equations, trying to take this to select the appropriate treatment program.
