Tooth loss replacement using dental implants is becoming more frequent. Traditional dental implant materials such as commercially pure titanium and titanium aluminum vanadium alloys have well-proven mechanical and biological properties. New titanium alloying metals such as niobium provide improved mechanical properties such as lower elastic modulus while displaying comparable or even better biocompatibility. Hydroxyapatite coatings are a well-documented and widely used method for enhancing dental implants' surface characteristics and properties and could provide a useful tool for further enhancing titanium-niobium implant properties like osteointegration. Among several coating techniques, physical deposition methods and, in particular, vapour deposition ones are the most used due to their advantages compared to wet deposition techniques for hydroxyapatite coating of metallic surfaces like that of dental implants. Considering the scarcity of data concerning the in vivo evaluation of titanium-niobium biocompatibility and osteointegration and the lack of studies investigating coating these new proposed alloys with hydroxyapatite, this review aims to further knowledge on hydroxyapatite-coated titanium niobium alloys.
使用牙种植体进行牙齿缺失修复的情况越来越普遍。传统的牙种植体材料，如商业纯钛和钛铝钒合金，具有经过充分验证的机械性能和生物学性能。新的钛合金化金属，如铌，具有改善的机械性能，如较低的弹性模量，同时表现出相当甚至更好的生物相容性。羟基磷灰石涂层是一种有充分文献记载且广泛应用的方法，用于增强牙种植体的表面特性和性能，并且可以为进一步增强钛铌种植体的骨整合等性能提供有用的工具。在几种涂层技术中，物理沉积方法，特别是气相沉积方法，由于与用于牙种植体等金属表面羟基磷灰石涂层的湿沉积技术相比具有优势，因而使用最为广泛。考虑到关于钛铌生物相容性和骨整合的体内评估数据稀缺，以及缺乏对这些新提出的合金进行羟基磷灰石涂层研究的情况，本综述旨在增进对羟基磷灰石涂层钛铌合金的了解。
