Abstract
A method of surface treatment for zirconium oxide implants and the etching formula for the same are disclosed. The processes are carried out at room temperature. The average surface roughness Ra and the standard deviation of the implant are measured showing significant improvement while comparing with the un-treated sample and the hydrofluoric acid treated samples. The average contact angle is provided showing an almost hydrophilic surface after etched by the formula according to the present invention.
