摘　　要：目的:研究不同前牙咬合类型人群的舌体位置,比较其各自的牙尖交错位与舌姿势位时舌位的差异。方法:筛选不同前牙错类型的受试者,利用舌背硫酸钡造影法,对受试者拍摄有特殊显影的常规牙尖交错位的侧位片及舌姿势位的侧位片,定位舌体的位置后找出其舌位变化特征。结果:除舌根部外,个别正常组从牙尖交错位到舌姿势位整个舌体下沉均匀;深覆组舌中部下沉量较大,其次是舌前部;深覆盖组舌中前部都有大幅度下沉;反组舌中后部下沉明显,而中前部仅有少量下沉量;开组下沉量是几组中最小的。结论:不同前牙咬合类型人群舌位的变化存在各自不同的特点,该特点可能与错本身存在一定的因果关系。Objective：To study the tongue charecteristics of different types of anterior occlusion,to compare the difference in intercuspal occlusion and tongue＇s natural resting position.Methods：Subjects with different types of anterior malocclusion were selected,and lateral cephalometric films were taken by tongue-dorsum barium sulfate filming method,in order to record the position of the body of tongue and to determine features in the alteration of tongue position.Results：The body of tongue except the root subsided evenly from intercuspal position（ICP）to tongue＇s natural resting position（TNRP）;in deep overbite group,the amount of tongue subsiding in the middle of tongue was most obvious,followed by the front of tongue;in deep overjet group,obvious subsiding in the front and middle of tongue was observed;significant subsiding was demonstrated in the middle and back in anterior crossbite group;the amount of subsiding in open bite group was least significant.Conclusion：Differential characteristics were observed in different types of occlusion,which may be correlated with the occlusion itself.
