[Research progress on surface treatment technology of zirconia implant]

Zirconia material has a color closer to human natural teeth, and has excellent mechanical properties and good biocompatibility, therefore it is expected to become an ideal material for dental implants. In order to improve the osteogenic properties of zirconia implants, a variety of surface treatment techniques emerge in two categories: non-coating method and coating method. Different surface treatment technologies have their advantages and disadvantages. In this paper, the recent progress of zirconia surface treatment technology is reviewed.
