Titanium dental implants have wide clinical application due to their many advantages, including comfort, aesthetics, lack of damage to adjacent teeth, and significant clinical effects. However, the failure of osseointegration, bone resorption, and peri-implantitis limits their application. Physical-chemical and bioactive coatings on the surface of titanium implants could improve the successful rate of dental implants and meet the clinical application requirements. This paper reviews the characteristics of surface modification of titanium implants from the aspects of physics, chemistry, and biology. Results provide information for research and clinical application of dental implant materials.
钛种植体具有美观舒适、不损伤邻牙、临床效果显著等优点，广泛应用于口腔种植修复领域；但应用中存在骨结合失败、种植体周围骨吸收、种植体周围炎等问题，使其应用受到一定的限制。对钛种植体进行表面改性，在其表面制备不同的理化涂层和生物活性涂层，可以提高种植体的种植成功率，满足临床应用需求。本文从物理、化学、生物三方面对各种钛种植体表面改性方法的特点进行总结，为牙种植材料的研究和临床应用提供参考.
