摘　　要：应用电子计算机对17例安氏Ⅱ类错(牙合),21例安氏Ⅲ类错(牙合)的颞颌关节间隙面积进行计算,以确定牙尖交错位(ICP)时髁突的位置。其结果为Ⅱ类错(牙合)的髁突大多居中位。Ⅱ类错(牙合)大多居前位。应用下颌运动描记仪(MKG)对其中各16例错(牙合)进行检查,其结果为Ⅱ类错(牙合)大多有 ICP 后移位,Ⅲ类错(牙合)大多有 ICP 前移位。此结果供临床医生在诊断与治疗错(牙合)时参考。To explore the properties of condylar position and the spatial relationship between intercuspal position(ICP)andmandibular postural position in the cases with Angle's Ⅱand Ⅲmalpcclusions,17 and 21 Angle's Ⅱand Ⅲmaloc-clusions were examined by TMJ multitomograph and mandibular kinesiograph(MKG)respectively.Based on thecomputer-aid TMJ space area analysis and measurement of MKG trajectories,following results were found:1)Centrallocation and anterior dislocation of condylar position were demonstrated in the most of Angle's Ⅱand Ⅲmalocclusioneases,respectively.2)ICP posterior and anterior displacements were demonstrated in the most of Angle's Ⅱand Ⅲmalocclusion cases,respectively.3)There are no significant correlation between condylar dislocation and ICP displace-ment in both Angle's Ⅱand Ⅲmalocclusions.The results may be taken as a reference to diagnose and treat these twomalocclusions.
