Implant dentistry has become a popular restorative option in clinical practice. Titanium and titanium alloys (TTA) are the gold standard for endo-osseus dental implants production, thanks to their biocompatibility, resistance to corrosion and mechanical properties. The characteristics of the TTA implant surface seem to be particularly relevant in the early phase of osseointegration. Furthermore, the microstructure of implant surface can largely influence the bone remodelling at the level of the bone-implant surface. Recently, research has stated on the long-term of both survival and success rates of osseointegrated implants and mainly on biomechanical aspects, such as load distribution and biochemical and histological processes at the bone-implant interface. This short review reports recent knowledge on chemical and mechanical properties, biological aspects, innovations in preventing peri-implantitis, describing clinical applications and recent improvements of TTA dental implants. In addition, it highlights current knowledge about a new implant coating that has been demonstrated to reduce the number of initially adhering bacteria and peri-implantitis.
种植牙科已成为临床实践中一种受欢迎的修复选择。钛及钛合金（TTA）是骨内牙种植体生产的金标准，这得益于它们的生物相容性、抗腐蚀性和机械性能。TTA种植体表面的特性在骨结合的早期阶段似乎尤为重要。此外，种植体表面的微观结构在很大程度上会影响骨-种植体表面水平的骨重塑。最近，研究主要集中在骨结合种植体的长期生存率和成功率，以及生物力学方面，如载荷分布和骨-种植体界面的生化及组织学过程。这篇简短综述报告了关于TTA牙科种植体的化学和机械性能、生物学方面、预防种植体周围炎的创新、临床应用及近期改进的最新知识。此外，它还强调了关于一种新的种植体涂层的当前知识，该涂层已被证明可减少初始附着细菌的数量和种植体周围炎。
