Objective: in order to afford the reference for clinically positing the height of bracket bonded, the cusp height of normal occlusion model and the height of bracket bonded be measured.
目的：测量正常合模型各个牙齿的牙尖高度，并以此为依据，确定托槽的粘贴高度，为临床上进行托槽粘贴高度的定位提供一定的参考。
Results: The geometric feature parameters of 28 artificial teeth in their own coordinates were obtained, including the mesiodistal and buccolingual dimension, the height and inclination of cusp.
结果：得到28颗人工牙的颊舌径、近远中径、牙尖高度、中央窝深度、牙尖平衡斜面斜度的数据。
