To evaluate how occlusal positions affect posture control system in children, a three-dimensional head sway measuring device was used. Head sway is related to the control system for posture, 10 children in the IIA period on Hellman's dental age scale and 10 adults were studied.Three occlusal conditions were selected : rest position of mandibula (rest position), bite touching on both sides (bite up using splints) and bite touching on one side (bite up using splint). Head sway was measured and analyzed separately for both standing and sitting positions.1. In standing position for adults, the degree of head sway in bite touching on both side were stable in rest position and that in bite touching on one side were unstable in them. The loci of head position were stable in bite up positions for children, but they can't recognize the difference between both sides and one side in bite touching.2. In sitting position for adults they can't recognize the difference between rest position and bith touching on both sides but touching on one side was grater than the others. For children the can't recognize the difference in three occlusal conditions.3. In both standing and sitting positions, the degree of head sway in three occlusal conditions i children was greater than in adults.

为了评估咬合位置如何影响儿童的姿势控制系统，使用了三维头部摇摆测量装置。头部摇摆与姿势控制系统有关，对10名赫尔曼牙齿年龄量表IIA期儿童和10名成人进行了研究。选择了三种咬合状态：下颌静止位置（restposition）、两侧咬合接触（bite touch）使用夹板咬合）并咬触一侧（使用夹板咬合）。分别对站立和坐姿的头部摆动进行测量和分析。 1．成人站立位时，休息位时两侧咬触的头部晃动程度稳定，一侧咬触的头部晃动程度不稳定。儿童在咬合姿势下头部位置轨迹稳定，但在咬合接触时不能区分两侧和一侧的差异。2．成年人在坐姿时，他们无法识别休息位置和两侧触摸之间的区别，但一侧的触摸比其他一侧更大。对于儿童来说，无法识别三种咬合状况的差异。3．在站立和坐姿中，儿童在三种咬合状态下的头部摇摆程度均大于成人。
