Abstract:

Temporomandibular joint（TMJ）is one of the most complex joints of the human body. For its deep location，we often need the help of imaging methods to study it. Because of image overlap and distortion，the traditional two-dimensional imaging methods are not accurate. Cone beam CT（CBCT）overcomes the shortcomings of the traditional two-dimensional imaging methods，and can analyze the TMJ in three-dimensional direction，which is important to the clinical diagnosis and pathological treatment.

Key words: temporomandibular joint, TMJ；CBCT

摘要：

颞下颌关节是人体最复杂关节之一，其位置深在，常需要借助影像学检查方法加以研究。传统的二维影像检查方法由于影像重叠及失真，影响其准确性，而锥形束CT克服了这些缺点，能够在三维方向上对颞下颌关节进行分析，对临床诊断及病理治疗具有重要作用。
