此文列表来估计尖牙和切牙移动对前牙弓弧长的影响。这些表是用几何学来描述的。在非Ⅰ类磨牙(牙合)的病例中,通常考虑牙弓间的前后矫正。在恒牙列Ⅱ类磨牙关系拔除下双尖牙使第一磨牙前移达到Ⅰ类(牙合)关系。当医生要求内收牙齿且相对于基骨比较直立的位置
This article lists the effects of canine and incisor movement on the arc length of the anterior arch. These tables are described in terms of geometry. In cases other than Class I molars, the anterior-to-posterior alignment of the interdental arch is usually considered. In the permanent dentition relationship between type Ⅱ molar removal of the canine to move the first molar reached Class Ⅰ (occlusal) relationship. When the doctor asks for adduction of the teeth and relatively upright position relative to the base bones
