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.

本研究检查了咀嚼软食物和硬食物时的首选咀嚼侧，并比较了颞下颌关节（TMJ）的前盘位移（ADD）和下颌切点（MMIP）的运动。在没有 TMJ ADD 的受试者中，在咀嚼软食和硬食时未观察到 MMIP 的侧向性。在患有单侧颞下颌关节ADD的受试者中，在咀嚼硬食物时观察到不平衡的MMIP。此外，可以假定 MMIP 的偏侧性与 ADD 的一侧相对应。
