标准X线投照法揭示颞下颌关节紊乱病变严重程度的探讨

Study on Measurement of Severity of the TMJ Pathology with Standardized X-ray Projections

应用颞颌关节侧位及个体校正侧位、经髁突长轴中份层面的个体校正侧位体层、同样头位同一层面的上腔或下腔造影X线检查,可揭示颞下颌关节内骨病变、盘病变的严重程度,对患者进行分类,作为标准诊断法。经华西医科大学口腔医院颞颌关节专科门诊实践,证实此法有效、可靠。文中介绍了常用的颞下颌关节X线检查方法的特点。并强调头位固定及髁突长轴水平角校正的重要性。

A standardized X-ray projections including lateral transcranial,or corrected lateraltranscranial,corrected tomography of central section of the joint,and corrected arthro-tomography of upper or inferior compartment of the joint through the same section wereused to measure severity of the bone or disk pathology of the TMJ.Diagaoses based onthese imaging were used as standardized classifications of severity of TMJ pathology.The TMJ Clinic of the College of Stomatology,WCUMS has confirmed that the class-ifications based on these projections are valid and reliable.Features of the variousprojections are described and the importance of fixation of head position for correctionof long axis of the condyle is emphasized.
