Titanium and its alloys are increasingly important in dentistry. Thin titanium nitride (TiN) coatings improve properties of metallic material for industrial purposes. Recently TiN coatings have been advocated in dentistry. In a survey of the literature, aspects of biological, mechanical and corrosive behaviour are assessed. Moreover, specific problems for clinical application are indicated. It is concluded that as long as the integrity of the TiN coating is not guaranteed under critical conditions, one should be cautious with its clinical application, and in no situation can it be used to improve deficient dental alloys.
钛及其合金在牙科领域日益重要。薄的氮化钛（TiN）涂层可改善金属材料的性能以用于工业目的。最近，TiN涂层在牙科领域得到了提倡。在对文献的调查中，对其生物学、力学和腐蚀行为等方面进行了评估。此外，还指出了临床应用中的具体问题。得出的结论是，只要在关键条件下不能保证TiN涂层的完整性，就应谨慎对待其临床应用，并且在任何情况下都不能用它来改善有缺陷的牙科合金。
