Balancing-side contacts were precisely evaluated in relation to internal derangements of the temporomandibular joint. Balancing-side contacts were classified into the three following groups: 1) Severe balancing-side interference, 2) balancing-side interference and 3) balancing-side protective contacts. Balancing-side protective contacts were defined as balancing-side occlusal contacts on lower first and/or second molar in lateral excursive movements, which are observed only when clenching forces are exerted. The prevalence of the balancing-side protection was revealed to be highly correlated with that of internal derangements of temporomandibular joint. These results strongly suggest that balancing-side protection might play an important role as a regulating mechanism in the etiology of internal derangements of temporomandibular joint.
对颞下颌关节内紊乱相关的平衡侧接触进行了精确评估。平衡侧接触分为以下三组：1）严重平衡侧干扰；2）平衡侧干扰；3）平衡侧保护性接触。平衡侧保护性接触定义为在侧方运动时，仅在施加紧咬力时观察到的下颌第一和/或第二磨牙上的平衡侧咬合接触。结果显示，平衡侧保护的发生率与颞下颌关节内紊乱的发生率高度相关。这些结果有力地表明，平衡侧保护可能作为一种调节机制，在颞下颌关节内紊乱的病因学中发挥重要作用。
