A study of the relationship between unilateral anterior disc displacement of temporomandibular joint and prefered chewing side

本研究比较了咀嚼软质和硬质食物时，下颌关节盘前移(ADD)和下颌切点移动(MMIP)对咀嚼侧的影响。在没有添加TMJ的受试者中，在咀嚼软的和硬的食物中没有观察到MMIP的偏侧性。在单侧增加TMJ的受试者中，观察到咀嚼坚硬食物时MMIP的失衡。此外，可以假设MMIP的偏侧性对应于ADD的一侧。

This study examined the preferred chewing side with comparison to the anterior disc displacement(ADD) of temporomandibular joint(TMJ) and the movement of mandibular incisal point(MMIP) in chewing soft and hard foods. In subjects without ADD of TMJ, a laterality of MMIP was not observed in chewing soft and hard foods. In subjects with unilateral ADD of TMJ, unbalanced MMIP was observed in chewing hard food. Moreover a laterality of MMIP could be assumed to be with correspondence to a side of ADD.
