The concept of canine protection and group function lack consistency in the definitions and examining methods, and a valid system for evaluating and classifying occlusal contact patterns has not been established.
This study assessed the use of canine protection and group function in classifying occlusal guidance in the natural dentition.
Occlusal contacts of 86 young adults were examined with shim stock in regulated lateral positions, 0.5,1,2 and 3 mm from the maximum intercuspation. The patterns of occlusal contacts varying with the lateral position were described.
Focusing on the working-side contact only, most contact patterns belonged to group function, and a few to canine protection. Focusing on both the working and nonworking side contacts, nearly half the contact patterns were those other than canine protection and group function and were classified into balanced occlusion.
The validity of the classification system using canine protection and group function is questionable. A new classification system of occlusal guidance is desirable.
犬牙保护和组牙功能的概念在定义和检查方法上缺乏一致性，并且尚未建立有效的咬合接触模式评估和分类系统。
本研究评估了犬牙保护和组牙功能在自然牙列咬合引导分类中的应用。
使用薄垫片在调节后的侧方位置对86名年轻成年人的咬合接触进行检查，该位置距离最大牙尖交错位分别为0.5、1、2和3毫米。描述了随侧方位置变化的咬合接触模式。
仅关注工作侧接触时，大多数接触模式属于组牙功能，少数属于犬牙保护。同时关注工作侧和非工作侧接触时，近一半的接触模式不属于犬牙保护和组牙功能，被归类为平衡咬合。
使用犬牙保护和组牙功能的分类系统的有效性值得怀疑。需要一种新的咬合引导分类系统。
