根据不同病变情况，镜下采取清理滑膜、咬除或刨削退变的软骨、修整不平的关节面和骨质面、磨除增生的骨赘、软骨下微钻孔减压、咬除并修整损伤盂唇、取出游离体、生理盐水灌洗关节腔等治疗手段。

This simplified method combined with crown lengthening procedure and occlusal rehabilitation, the problems of insufficient interarch space and gummy smile were resolved without neither orthodontic treatment nor alteration of the occlusal vertical dimension.

本病例报告为一女性患者因长期局部缺牙，因而丧失赝复空间，在不改变其咬合垂直高度为前提下，施行上颚半口及下颚后牙之牙冠增长术，并提高其咬合平面，最后上颚以固定式局部义齿、下颚以固定式义齿合并植牙来赝复，赝复空间不足的问题已解决，病人微笑时过多牙龈暴露的情形也获得改善。

The morphologic change in periodontium and alveolar may be related to IL-6 expression.
