摘要: 钛及钛合金因其优异的力学性能、耐腐蚀性和生物相容性,被广泛用作牙种植体材料。然而钛基牙种植体在临床使用中因软组织封闭不佳,细菌容易侵入诱发种植体周炎,导致种植体植入手术失败。因此,为钛基牙种植体赋予软组织封闭能力以有效降低种植体植入手术的失败率,国内外研究者对此作了持续、深入的研究。本文综述了近年来钛基牙种植体软组织封闭表面改性研究系列进展,着重介绍了钛表面化学组分调控和微纳结构构建方法,指出了钛基牙种植体软组织封闭表面改性研究中尚存的挑战以及未来发展趋势,以期为钛基牙种植体软组织封闭研究提供参考。

Abstract: Titanium and its alloys are widely used as dental implant materials due to their excellent mechanical property, corrosion resistance and biocompatibility. However, in clinical applications, titanium-based dental implants often suffer from poor soft tissue sealing, allowing bacteria to invade and induce peri-implantitis, leading to final implant failure. To address these issues and reduce the failure rate of implant surgery effectively, researchers worldwide have conducted extensive and in-depth studies. This article reviews recent advancements in surface modification strategies for improving soft tissue sealing on titanium-based dental implants, with the focus on methods for regulating surface chemical composition and constructing micro-nano structures. Additionally, it highlights the existing challenges and future trends in this field, aiming to provide valuable insights for further research on soft tissue sealing of titanium-based dental implants.
