Titanium and its alloys are used in dentistry for implants because of its unique combination of chemical, physical, and biological properties. They are used in dentistry in cast and wrought form. The long term presence of corrosion reaction products and ongoing corrosion lead to fractures of the alloy-abutment interface, abutment, or implant body. The combination of stress, corrosion, and bacteria contribute to implant failure. This article highlights a review of the various aspects of corrosion and biocompatibility of dental titanium implants as well as suprastructures. This knowledge will also be helpful in exploring possible research strategies for probing the biological properties of materials.
钛及其合金因其化学、物理和生物学特性的独特组合而被用于牙科植入物。它们以铸造和锻造形式应用于牙科。腐蚀反应产物的长期存在和持续腐蚀会导致合金-基台界面、基台或种植体主体的断裂。应力、腐蚀和细菌共同作用会导致种植体失效。本文重点综述了牙科钛植入物以及上部结构的腐蚀和生物相容性的各个方面。这些知识也将有助于探索研究材料生物学特性的可能研究策略。
