目的是研究牙尖斜度的三维测量方法。
The objective was to study a 3D-measurement for cuspal inclination.
高牙尖斜度与非中心线负载可引起高应力集中。
Higher inclination of cusp and non central loading lead to higher stress.
目的：研究牙尖斜度的三维测量方法，从牙体解剖方面探讨磨牙隐裂病因。
Objective:To study a 3D-measurement for cuspal inclination and evaluate the anatomical etiology of the cracked molars.
建议种植体的牙尖斜度控制在20 ~25“之间，并将与对领牙的胎接触关系调为ab两点接触。”
Therefore, we recommend a cusp inclination is limited between 20 to 25 degree, and the compatible occlusion contact is AB two points contact.
结论腭穹隆形状、牙尖斜度和人工牙的排列位置对上颌全口义齿牙槽骨的应力集中状况有明显的影响作用。
Conclusion the palatal vault, cusp inclination and the position of artificial teeth have apparent influence upon the stress concentration on the alveoli dentales maxillae.
