The invention discloses a zirconia dental implant surface treatment method which comprises the steps of cleaning, sand blasting treatment, acid etching, soaking and sintering. In the invention, the zirconia dental implant surface is dipped with a ball-milled zirconia suspension; the pore diameter of pores in the zirconia dental implant surface is controlled by use of different particle sizes of the ball-milled zirconia powder; meanwhile, due to the sand blasting and acid etching treatment before soaking, the surface roughness of false teeth is increased to certain degree; with later sintering, the surface roughness of false teeth is remarkably increased; and thus, the interfacial effect between the implant material and the host bone can be improved, the binding capacity between the implant and the bone is enhanced, and clinical success rate of dental implant is increased. The zirconia dental implant surface treatment method is simple in operation, convenient in treatment, low in cost and suitable for industrialized large-scale production.
