Abstract
Osseointegration is a major factor influencing the success of dental implantation. To achieve rapid and strong, durable osseointegration, biomaterial researchers have investigated various surface treatment methods for dental subgingival titanium (Ti) implants. This paper focuses on surface-charge modification on the surface of titanium dental implants, which is a relatively new and very promising methodology for improving the implants' osseointegration properties. We give an overview on both theoretical explanations on how surface-charge affects the implants' osseointegration, as well as a potential surface charge modification method using sandblasting. Additionally, we discuss insights on the important factors affecting effectiveness of surface-charge modification methods and point out several interesting directions for future investigations on this topic.
摘要
骨结合是影响牙种植成功的一个主要因素。为了实现快速、牢固且持久的骨结合，生物材料研究人员对牙种植体龈下钛（Ti）种植体的各种表面处理方法进行了研究。本文重点关注牙科钛种植体表面的表面电荷修饰，这是一种相对较新且非常有前景的改善种植体骨结合特性的方法。我们概述了关于表面电荷如何影响种植体骨结合的理论解释，以及一种使用喷砂的潜在表面电荷修饰方法。此外，我们讨论了影响表面电荷修饰方法有效性的重要因素的见解，并指出了关于该主题未来研究的几个有趣方向。
