目的:运用锥束CT(CBCT)分析比较安氏Ⅱ类2分类错(牙合)与个别正常(牙合)关节位置的差异。方法选择符合试验设计的23例安氏Ⅱ类2分类错(牙合)患者为试验组,27例个别正常!为对照组。研究对象拍摄 CBCT,使用 Examvision软件在垂直于髁突长轴的斜位重建影像后,导入 AutoCAD计算机软件进行关节间隙测量,测量髁突在关节窝中的位置,并对结果进行比较。结果安氏Ⅱ类2分类错!患者中65.2%髁突后移位,个别正常(牙合)中64.8%髁突处于中间位。结论安氏Ⅱ类2分类错(牙合)患者相对于个别正常(牙合)关节位置异常,应早期矫治,诱导关节到正常位置,避免产生关节症状。
目的:運用錐束CT(CBCT)分析比較安氏Ⅱ類2分類錯(牙閤)與箇彆正常(牙閤)關節位置的差異。方法選擇符閤試驗設計的23例安氏Ⅱ類2分類錯(牙閤)患者為試驗組,27例箇彆正常!為對照組。研究對象拍攝 CBCT,使用 Examvision軟件在垂直于髁突長軸的斜位重建影像後,導入 AutoCAD計算機軟件進行關節間隙測量,測量髁突在關節窩中的位置,併對結果進行比較。結果安氏Ⅱ類2分類錯!患者中65.2%髁突後移位,箇彆正常(牙閤)中64.8%髁突處于中間位。結論安氏Ⅱ類2分類錯(牙閤)患者相對于箇彆正常(牙閤)關節位置異常,應早期矯治,誘導關節到正常位置,避免產生關節癥狀。

Objective To analyze and compare the difference of the joint position between the Angle classⅡ division 2 malocclu-sion and individual normal occlusion by dental cone beam computed tomography (CBCT).Methods 23 patients with Angle classⅡdivision 2 malocclusion according with the experimental design were selected as the experimental group and 27 cases of individual normal occlusion as the control group.Each research subj ect was performed CBCT.The images in the oblique position perpendicular to the long axis of condyloid process were reconstructed by the Examvision software.Then the joint space was measured by the Au-toCAD software and and the positional relation of the condyloid process in the articular fossa was assessed by Pullinger analysis methods.The results were compared.Results 65.2% of the condylloid process in Angle classⅡ division 2 malocclusion is posteri-orly shifted,in individual normal occlusion,64.8% of the condylloid process is in the middle place.Conclusion The condylar posi-tion of Angle classⅡ division 2 malocclusion were abnormal relative to individual normal occlusion joint,which should be early cor-rected for inducing the joint to the normal position and avoiding the generation of the joint symptoms.
