Bruxism (tooth grinding and clenching) is generally considered a contraindication for dental implants, although the evidence is usually based on clinical experience only. So far, studies to the possible cause-and-effect relationship between bruxism and implant failure do not yield consistent and specific outcomes. This is partly due to the large variation in the technical and the biological aspects of the investigations. Although there is still no proof that bruxism causes overload of dental implants and their suprastructures, a careful approach is recommended. Practical advices as to minimize the chance of implant failure are given. Besides the recommendation to reduce or eliminate bruxism itself, these advices concern the number and dimensions of the implants, the design of the occlusion and articulation patterns, and the use of a hard nightguard.
磨牙症（牙齿磨动和紧咬）通常被视为牙种植体的禁忌证，尽管相关证据通常仅基于临床经验。到目前为止，关于磨牙症与种植体失败之间可能的因果关系的研究并未得出一致且明确的结果。部分原因在于研究在技术和生物学方面存在很大差异。尽管尚无证据表明磨牙症会导致牙种植体及其上部结构过载，但仍建议谨慎处理。文中给出了一些实用建议，以尽量降低种植体失败的几率。除了建议减少或消除磨牙症本身外，这些建议还涉及种植体的数量和尺寸、咬合和关节模式的设计以及使用硬质夜磨牙垫。
