偏侧咀嚼为颞下颌关节紊乱综合征(TMJDS)的重要病因之一。临床中长期偏侧咀嚼的病人常有双侧关节不对称改变,但尚未见到偏侧咀嚼对颞下颌关节结构影响的专门报道。本文在TMJDS病人中,对有偏侧咀嚼现象患者,分析颞下颔关节X光片测量结果,探讨咀嚼侧关节和非咀嚼侧的结构改变;研究偏侧咀嚼病人颞下颌 Unilateral chewing is one of the important causes of temporomandibular disorder (TMJDS). Long-term clinical patients with unilateral mastication often have asymmetric bilateral joint changes, but not yet seen the effects of unilateral chewing on the temporomandibular joint structure of the special report. In TMJDS patients, patients with unilateral chewing, analysis of the results of the measurement of the infratemporal X-ray films, to explore the chewing side of the joint and non-chewing side of the structural changes; unilateral chewing patients temporomandibular
