摘　　要：目的:研究深覆及正常人群在舌姿势位时的舌矢状向的大小及舌位特征。方法:利用舌背硫酸钡造影法,对受试者拍摄有特殊显影的舌姿势位的侧位片,定位舌体的位置及舌体的高度及长度,比较深覆与正常的差异性。结果:深覆人群的舌前中部都较低位,舌前部也较为后缩,舌长度及高度也较正常稍小,差异有显著性。结论:深覆与正常人群存在不同的舌姿势位特征,这可能与错本身存在一定的因果关系。Objective： To study the sagittal size and characteristics of tongue under tongue resting position in the subjects with deep-overbite and normal occlusion. Methods： By tongue-dorsum barium sulfate filming method, the subjects were taken lateral cephalometric films in order to record the position, length and height of the body of tongue. And then the difference between two groups was compared. Results： In the deep-overbite group, the front and middle part,,of tongue were in the relatively low position and the front parts were retruded. And their length and height were relatively smaller than those of normal occlusion group. The difference was statistically significant. Conclusion： Different characteristics between deep-overbite group and normal occlusion group may correlate with the occlusion.
