氧化锆基生物陶瓷是近30年来发展起来的一种新型牙种植体材料。然而，由于制造困难、低温降解（LTD）、长期稳定性和临床经验等因素，氧化锆植入物仍存在一些局限性。一些研究证实，氧化锆表面的一些细微变化可能会显著影响其机械性能和骨整合。因此，氧化锆种植体的表面改性效果受到了人们的关注。本文综述了目前氧化锆种植体表面改性的研究进展，主要分为物理处理、化学处理和表面涂层三大类，并结合目前的研究现状，对氧化锆种植体的表面改性进行了全面的介绍。因此，表面改性是氧化锆种植体应用的有效和必要的方法。然而，在临床使用之前，我们需要对这些修饰方法有更多的了解。
Zirconia-based bioceramic is a potential material for dental implants developed and introduced in dentistry 30 years ago. However, some limitations still exist for zirconia implants caused by several factors, such as manufacturing difficulties, low-temperature degradation (LTD), long-term stability, and clinical experience. Several studies validated that some subtle changes on the zirconia surface might significantly impact its mechanical properties and osseointegration. Thus, attention was paid to the effect of surface modification of zirconia implants. This review generally summarizes the surface modifications of zirconia implants to date classified as physical treatment, chemical treatment, and surface coating, aiming to give an overall perspective based on the current situation. In conclusion, surface modification is an effective and essential method for zirconia implant application. However, before clinical use, we need more knowledge about these modification methods.
