多年來,諸多研究曾探討外力對牙周組織的作用,但經常因外力的種類、大小、作用時間和原本的牙周組織是否有病變等因素,而使得研究結果皆不盡相同。其中,各研究中所使用的外力則包括有不正常的咬合接觸、矯正力、反覆震動力和強大的衝擊力等等。另外,不同的研究動物、和不同的實驗方法等也可能導致不同的結果。本文擇要的介紹歷年來有關於外力對牙周組織作用的各種研究報告,及吾等認同於外力對牙周組織會產生影響的實驗觀察結果,以期提供研究和臨床上的參考依據。

It has been tremendous documentation concerning the effects of mechanical stress on the periodontium. However, the results remain controversial. It may be due to the variations derived from different types, duration, or magnitute of stress. The types of stress include abnormal chewing habits, orthodontic force, occlusal overloading, jiggling force, and also the strong load such as motor-car accidents. In addition, various animal models, examination parameters and study methods may also lead to different results. The purpose of this comprehensive review is to evaluate the influences of the mechanical stress on the periodontal tissues.
