Titanium has been considered as one of the most biocompatible metals. Studies testing its corrosion resistance have proposed that the titanium oxide layer formed on the metal surface is lost under certain unavoidable conditions to which it is exposed in the oral environment. This questions its property of corrosion resistance in the oral cavity. Hence, there is a need to understand the mechanisms of corrosion, which can help in the long-term stability and function of implants. Here, we review the possible pathways of corrosion of titanium in the oral cavity, its implications and proposed methods of prevention of corrosion.
钛被认为是生物相容性最佳的金属之一。测试其耐腐蚀性的研究表明，在口腔环境中，金属表面形成的氧化钛层在某些不可避免的条件下会消失。这对其在口腔中的耐腐蚀性能提出了质疑。因此，有必要了解腐蚀机制，这有助于植入物的长期稳定性和功能。在此，我们综述了口腔中钛的可能腐蚀途径、其影响以及提出的防腐蚀方法。
