For decades titanium has been the preferred material for dental implant fabrication, with mechanical and biological performance resulting in high clinical success rates. These have been further enhanced by incremental development of surface modifications aimed at improving speed and degree of osseointegration and resulting in enhanced clinical treatment options and outcomes. However, increasing demand for metal-free dental restorations has also led to the development of ceramic-based dental implants, such as zirconia. In orthopedics, alternative biomaterials, such as polyetheretherketone or silicon nitride, have been used for implant applications. The latter is potentially of particular interest for oral use as it has been shown to have antibacterial properties. In this article we aim to shed light on this particular biomaterial as a future promising candidate for dental implantology applications, addressing basic specifications required for any dental implant material. In view of available preclinical data, silicon nitride seems to have the essential characteristics to be a candidate for dental implants material. This novel ceramic has a surface with potentially antimicrobial properties, and if this is confirmed in future research, it could be of great interest for oral use.
几十年来，钛一直是制造牙科植入物的首选材料，其机械性能和生物学性能带来了很高的临床成功率。旨在提高骨整合速度和程度的表面改性技术的不断发展进一步提升了这些成功率，从而带来了更多的临床治疗选择和更好的治疗效果。然而，对无金属牙科修复体的需求不断增加，也促使了基于陶瓷的牙科植入物的发展，例如氧化锆。在骨科领域，聚醚醚酮或氮化硅等替代生物材料已被用于植入物应用。氮化硅因其已被证明具有抗菌特性，在口腔应用方面可能特别受关注。在本文中，我们旨在阐明这种特殊的生物材料作为牙科植入学应用未来有前景的候选材料的情况，讨论任何牙科植入材料所需的基本规格。鉴于现有的临床前数据，氮化硅似乎具备成为牙科植入材料候选者的基本特性。这种新型陶瓷具有潜在的抗菌表面，如果在未来研究中得到证实，它在口腔应用方面可能会非常有吸引力。
