Prolonged inflammation induced by orthopedic metallic implants can critically affect the success rates, which can even lead to aseptic loosening and consequent implant failure. In the case of adverse clinical conditions involving osteoporosis, orthopedic trauma and implant corrosion-wear in peri-implant region, the reactive oxygen species (ROS) activity is enhanced which leads to increased oxidative stress. Metallic implant materials (such as titanium and its alloys) can induce increased amount of ROS, thereby critically influencing the healing process. This will consequently affect the bone remodeling process and increase healing time. The current review explores the ROS generation aspects associated with Ti-based metallic biomaterials and the various surface modification strategies developed specifically to improve antioxidant aspects of Ti surfaces. The initial part of this review explores the ROS generation associated with Ti implant materials and the associated ROS metabolism resulting in the formation of superoxide anion, hydroxyl radical and hydrogen peroxide radicals. This is followed by a comprehensive overview of various organic and inorganic coatings/materials for effective antioxidant surfaces and outlook in this research direction. Overall, this review highlights the critical need to consider the aspects of ROS generation as well as oxidative stress while designing an implant material and its effective surface engineering.
骨科金属植入物引起的长期炎症会严重影响成功率,甚至可能导致无菌性松动以及随之而来的植入物失效。在涉及骨质疏松症、骨科创伤和植入物周围区域腐蚀磨损等不良临床情况时,活性氧(ROS)活性增强,导致氧化应激增加。金属植入材料(如钛及其合金)可诱导ROS生成量增加,从而严重影响愈合过程。这进而会影响骨重塑过程并延长愈合时间。本综述探讨了与钛基金属生物材料相关的ROS生成方面,以及专门为改善钛表面抗氧化性能而开发的各种表面改性策略。本综述的第一部分探讨了与钛植入材料相关的ROS生成以及导致超氧阴离子、羟基自由基和过氧化氢自由基形成的相关ROS代谢。接下来是对用于有效抗氧化表面的各种有机和无机涂层/材料的全面概述以及该研究方向的展望。总体而言,本综述强调了在设计植入材料及其有效表面工程时考虑ROS生成以及氧化应激方面的迫切需求。
