目的：通过锥形束CT三维成像研究单侧后牙正锁患者颞下颌关节的骨性特征。方法对35例安氏Ⅰ类单侧后牙正锁患者（实验组单侧后牙正锁患者19例，对照组安氏Ⅰ类无锁患者16例）使用口腔专用锥形束CT（CBCT）影像扫描。利用Ondemand3D软件中DentalVolumeReformat功能行三维重建，选择描述颞下颌关节骨性结构的9个点进行描记，对11个测量值进行分析统计。结果实验组锁侧与非锁侧比较颞下颌关节骨性形态差异有统计学意义（P＜0．01）；对照组左右两侧差异无统计学意义（P＞0．05）。对照组与实验组锁侧和非锁侧分别比较，颞下颌关节骨性形态差异均有统计学意义（P＜0．01）。结论CBCT成像能有效分析颞下颌关节的骨性形态特征，单侧后牙正锁患者两侧髁突及关节窝具有形态学差异。
目的：通過錐形束CT三維成像研究單側後牙正鎖患者顳下頜關節的骨性特徵。方法對35例安氏Ⅰ類單側後牙正鎖患者（實驗組單側後牙正鎖患者19例，對照組安氏Ⅰ類無鎖患者16例）使用口腔專用錐形束CT（CBCT）影像掃描。利用Ondemand3D軟件中DentalVolumeReformat功能行三維重建，選擇描述顳下頜關節骨性結構的9箇點進行描記，對11箇測量值進行分析統計。結果實驗組鎖側與非鎖側比較顳下頜關節骨性形態差異有統計學意義（P＜0．01）；對照組左右兩側差異無統計學意義（P＞0．05）。對照組與實驗組鎖側和非鎖側分彆比較，顳下頜關節骨性形態差異均有統計學意義（P＜0．01）。結論CBCT成像能有效分析顳下頜關節的骨性形態特徵，單側後牙正鎖患者兩側髁突及關節窩具有形態學差異。

Objective To analyze the skeletal characteristics of temporomandibular joint in patients with unilateral posterior scis-sors bite by using the cone-beam computed tomography(CBCT) .Methods Thirty-five patients of Angle class Ⅰ were scanned by CBCT (19 cases with unilateral scissors bite as the experimental group and 16 cases without scissors bite as the control group ) The CT images were reconstructed into 3D computer models by using the Dental Volume Reformat Function of the Ondemand 3D pack-age .9 anatomical landmarks were located and all data of 11 measured value were statistically analyzed .Results There were statisti-cal differences in the skeletal characteristics of temporomandibular joint in the scissors-bite side of the experimental group compared with those in the non-scissors-bite side (P<0 .01) .The side-to-side differences of the skeletal characteristics of temporomandibular in the controlled group were not statistically significant (P>0 .05) .There were statistical significances in the skeletal characteris-tics of temporomandibular joint of the controlled group compared with those in the scissors-bite side of the experimental group ,and the same with those in the non-scissors-bite side (P<0 .01) .Conclusion The CBCT is an effective tool to analyze the skeletal char-acteristics of temporomandibular joint characteristics .There were differences in the morphology of the condyle and the glenoid fossa of patients with unilateral posterior scissors bite .
