尽管氧化钇稳定的氧化锆（YSZ）具有化学惰性，但已有报道称其会粘附软硬组织。为了研究牙种植体中硬组织和软组织与YSZ粘附的潜在机制，将具有（100），（110）和（111）晶面的YSZ圆盘浸入水中60天和Hanks溶液中7天，并使用X射线光电子能谱表征表面化学状态的变化。在水中浸泡60天后，YSZ表面上的羟基基团的浓度增加。因此，YSZ表面在浸入水中时发生水合。此外，在Hanks溶液中浸泡的YSZ表面上形成了磷酸盐基团。我们的结论是，在生理条件下，磷酸盐在YSZ表面上的形成可以促进与周围组织的反应。
Adhesion of soft and hard tissues to yttria‐stabilized zirconia (YSZ) has been reported, despite its chemical inertness. To investigate the underlying mechanism of adhesion of hard and soft tissues to YSZ in dental implants, YSZ disks with (100), (110), and (111) crystalline planes were immersed in water for 60 days and in Hanks solution for 7 days, and the changes in the surface chemical states were characterized using X‐ray photoelectron spectroscopy. After immersion in water for 60 days, the concentration of hydroxyl groups on the YSZ surface increased. Therefore, the surface of YSZ was hydrated during immersion in water. In addition, phosphate groups were formed on the surface of YSZ immersed in Hanks solution. We conclude that the formation of phosphate on the YSZ surface in physiological conditions can promote reaction with the surrounding tissues.
