Numerous reports and surveys have been published on natural tooth abutment intrusion with implant-connected fixed partial dentures. The consensus of these publications was that the cause of intrusion was multifactorial, with causative factors such as disuse atrophy, debris impaction, impaired rebound memory, and mechanical binding. It was also believed that the process was irreversible.
In this article, the limitations with these theories are discussed, and two patient reports of tooth intrusion reversal are reviewed. A review of the current literature is discussed, as well as the current theory of tooth movement in response to dynamic mechanical stimulus, a brief discussion of current experimental procedures and results, and the current recommendations for reversal of intrusion.
关于种植体连接固定局部义齿天然牙基牙侵入的大量报告和调查已经发表。这些出版物的共识是，侵入的原因是多因素的，包括废用性萎缩、碎屑嵌塞、回弹记忆受损和机械束缚等致病因素。人们还认为这个过程是不可逆的。
在本文中，讨论了这些理论的局限性，并回顾了两例牙侵入逆转的患者报告。讨论了当前文献综述，以及当前关于牙齿对动态机械刺激反应的运动理论，简要讨论了当前的实验程序和结果，以及当前关于侵入逆转的建议。
