下颌关节

Condylar cartilage is a basic development center of mandible, and is very sensitive to the mechanical stress.

髁突软骨是下颌骨重要的生长发育中心，同时也是颞下颌关节髁突的应力敏感区。

The functional activities of mastication were restored. The temporomandibular joint disturbance syndrome and hypersusceptible symptoms disappeared or were alleviated.

结果：30例患者关系均恢复，面下1/3长度改善，颞下颌关节功能紊乱综合征和过敏症状消失或得到改善，咀嚼功能改善。

Methods: Fourteen patients of infraocclusion which was caused by defect of dentition or excessive abrasion with temporomandibular internal derangement were choosed, transitional prosthesis were applied to hoist the occlusions.

选取14例因牙列缺损或重度磨耗所致低位咬合同时伴有颞下颌关节结构紊乱患者，采用暂时性修复体升高咬合，3个月后待症状缓解行永久性修复治疗，治疗完成3个月后复查。

There were all different kinds of complication occurring during TEE examination concluding vomiting, minor mucus bleeding, laryngospasm, mandibular dislocation, angina pectoris, arrhythmia, even ventricular fibrillation and death.

结果提示： TEE检查可引起多种并发症，其中包括恶心、呕吐、粘膜损伤出血、喉痉挛、下颌关节脱位、心绞痛、心律失常，甚至出现心室纤颤和死亡。

A small and gradually TW was a physiological process accompanied by ones all life, but severe TW could cause a series of pathological changes between tooth and dentition, occlusion and articulation, the maxillomandibular relation and masticatory muscles. TW can affect the healthy between mastication and all correlated tissue.

少量的、逐渐的牙齿磨耗是伴随一生的生理过程，而重度磨耗可以引起牙与牙列、与咬合、颌间关系与颌周肌肉、颞下颌关节等发生一系列病理变化，从而影响到咀嚼功能和各相关组织的健康。

Compared with mouth closing, the IAP is significantly higher when the jaw is opened. Absence of the postglenoid process and the retrodiscal tissue following the movement of the mandibular condyle could contribute to the rise of IAP.

小型猪颞下颌关节无关节后结节，在开口运动中盘后组织跟随盘突运动是被动开口位压力升高为正值的重要解剖生理基础。

Over time, also cause gum disease, dentin hypersensitivity, also caused serious pulpitis, temporomandibular joint disease.

时间一长，还会引起牙周病，牙本质过敏症，严重的还可引起牙髓炎、颞下颌关节病。

Ten normal people as a control group.Measured NO content in TMD synovia with improved fluorometric assay.

采用改良荧光分光光度法检测下颌关节液中一氧化氮含量。

Abstract〕Objective: To study the role of cell proliferation and programmed cell death in the temporomandibular joint development .
