摘　　要：对100例单侧颞下颌关节紊乱病患者的双侧颞下颌关节进行锥形束CT(CBCT)扫描,测量关节的前、后和上间隙,并计算ln(P/A)值。可复性关节盘移位组的关节后间隙和上间隙都小于对照组,差异有统计学意义(P<0.05),而关节前间隙与对照组差异无统计学意义,且ln(P/A)值均小于对照组ln(P/A)值(P<0.05);不可复关节盘移位组的关节前、后和上间隙与对照组差异无统计学意义,且ln(P/A)值与对照组ln(P/A)值差异无统计学意义。单纯的颞下颌关节CBCT扫描显示关节间隙改变,尚不能作为关节盘移位的确切诊断依据。100 TMD patients scaned by CBCT and the joint tative measurements of joint space were applied to detect photographic images were saved. Two different quanti- anterior, posterior, superior joint space of the tern- poromandibular joint （TMJ）. The ln（P/A） values were calculated. The superior and posterior joint spaces of the affected sides of the anterior disc displacement with reduction were narrower than those of healthy sides significant- ly, while the anterior joint spaces had no significant differences between the affected and healthy sides. In addi- tion, there were significant differences in In （P/A） values （ P 〈 0. 05 ） ; as to the anterior disc displacement without reduction, there were no significant differences in the superior, anterior, posterior joint spaces. Articular disc dis- placement could not be diagnosed only by the posterior condyle position showed on the simple temporomandibular joint CBCT scanning.
