摘　　要：目的应用CBCT对无主观关节症状的成人安氏Ⅰ类、安氏Ⅱ类和安氏Ⅲ类成人错(牙合)畸形的髁突位置进行初步探索。方法选择安氏Ⅰ类、安氏Ⅱ类和安氏Ⅲ类成人错(牙合)畸形患者各15例进行CBCT扫描,应用CBCT专用软件Invivo 5.0分析测量颞下颌关节前间隙、上间隙、后间隙的距离,并运用SPSS 21.0软件包对三组数据进行统计学分析,比较安氏Ⅰ类、安氏Ⅱ类和安氏Ⅲ类成人错(牙合)畸形患者的髁突位置差异。结果三组数据关节前间隙、上间隙、后间隙单因素方差分析结果显示均具有组间差异,对其进行两两比较,关节前间隙安氏Ⅰ类组与安氏Ⅱ类组、安氏Ⅱ组与安氏Ⅲ类组间差异有统计学意义,关节上间隙和后间隙安氏Ⅰ类组与安氏Ⅲ类组、安氏Ⅱ组与安氏Ⅲ类组间差异均有统计学意义。髁突在关节窝的位置安氏Ⅰ类组主要表现居中位,占57%;安氏Ⅱ类组主要表现为髁突后移位,占70%;安氏Ⅲ类组主要表现为髁突前移位,占63%。结论安氏Ⅱ类患者关节前间隙大于安氏Ⅰ类和Ⅲ类;安氏Ⅲ类患者关节后间隙大于安氏Ⅰ类和Ⅱ类;安氏Ⅲ类患者关节上间隙小于安氏Ⅰ类和Ⅱ类。安氏Ⅰ类患者髁突居中位;安氏Ⅱ类患者髁突后移位;安氏Ⅲ类患者髁突前移位。Objective To analyze and compare the difference of condylar position among Angle ClassⅠ,ClassⅡand ClassⅢmalocclusion patients using cone-beam CT(CBCT).Methods15ClassⅠadults,15ClassⅡadults and15ClassⅢadults wereselected in this study.Each patient underwent CBCT.The temporomandibular joint parameters include the anterior joint space,superior joint space and posterior joint space.The condylar position were measured by Invivio5.0.The data were processed with SPSS21.0software package.Results:There were significant differences in the anterior joint space,superior joint space and posterior joint space among different malocclusion patients.The position of the condyle in the glenoid fossa was centered in the ClassⅠgroup(57%),was forward in the ClassⅡgroup(70%),and was backward in the ClassⅢgroup(63%).Conclusions The anterior joint space in patients with classⅡwas larger than that in patients with ClassⅠandⅢ;the posterior joint space in patients with ClassⅢwas larger than ClassⅠandⅡ;the superior joint space in patients with ClassⅢis smaller than ClassⅠandⅡ.Condylar medial position in classⅠpatients;posterior condylar displacement in classⅡpatients;antecondylar displacement in classⅢpatients.
