摘　　要：目的:比较恒牙列初期不同垂直骨面型患者颞下颌关节窝的形态特点。方法:采用计算机X线头影测量技术,对恒牙列初期不同垂直骨面型患者牙尖交错位颞下颌关节侧位体层片进行测量分析,比较各组间颞下颌关节窝的形态特点。结果:关节结节高度、关节窝高度、关节窝前斜面与水平基准线的夹角由大到小依次为低角组、均角组、高角组。关节窝前后斜面切线的夹角由大到小依次为高角组、均角组、低角组,关节窝宽度高角组比低角组、均角组明显增大。结论:恒牙列初期不同垂直骨面型患者的颞下颌关节窝形态有显著差异,低角骨面型患者的关节窝深而陡,高角骨面型患者关节窝浅而平,均角骨面型患者介于两者之间。Objective：To study the difference of glenoid fossa morphology with different vertical facial types of early permanent dentition patients. Method：TMJ corrected lateral tomogram radiographs of 111 malocclusion patients with differ-ent vertical facial types were measured and analysised by computerized cephalometrics technique. Glenoid fossa morphology was compared among different vertical facial type groups. Result：There were statistical difference in the height of articular tubercle and glenoid fossa,the angle of front bevel of glenoid fossa,the angle of front and back bevel of glenoid fossa among three groups.The width of glenoid fossa of high angle group is significantly larger than that of low angle and average angle group. Conclusion：The glenoid fossa morphology of early permanent dentition patients with different vertical facial type are significantly different. The glenoid fossa of low angle facial skeletal type patients is deep and steep. The high angle facial skeletal type patients is shallow and flat,The average angle facial skeletal type patients is between the first two.
