Metallic materials utilized for the construction of intra-oral and implant dental restorations include a wide range of relatively pure metals and multicomponent alloys. Basic corrosion and biodegradation properties of these alloys have been studied by both in vitro and in vivo techniques. These property characteristics have been shown to be dependent on composition and metallurgical state, combinations within a construct, surface conditions, mechanical aspects of function, and the local and systemic host environment. The susceptibility of these metallic materials to various forms of biodegradation will be presented, with emphasis on corrosion.
用于口腔内和种植牙修复体制造的金属材料包括多种相对纯的金属和多组分合金。这些合金的基本腐蚀和生物降解特性已通过体外和体内技术进行了研究。这些特性已被证明取决于成分和冶金状态、结构内的组合、表面条件、功能的机械方面以及局部和全身宿主环境。将介绍这些金属材料对各种生物降解形式的敏感性，重点是腐蚀。
