Problems solved by technology

However, zirconia ceramics are not easy to react with acid, so it is difficult to form an acid-etched porous structure on the implant surface
At the same time, after plasma spraying hydroxyapatite on the surface of the zirconia ceramic implant, due to the secondary sintering, faults will be formed on the implant surface, which affects the success rate of the implant.
At present, there is no systematic research on the surface treatment methods of zirconia ceramic implants.

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of oral restoration, and in particular relates to a method for treating the surface of a zirconia dental implant. Background technique [0002] With the continuous improvement of living standards and aesthetic requirements, implant denture restoration has become an important part of oral restoration. At present, titanium implants are mainly used clinically. In order to improve the ability of titanium implant-osseointegration and shorten the healing time, the surface of pure titanium implants is mostly treated. For example, the surface of the implant produced by the Swedish Nobel Company has been treated with TiUnite (titanium easy-resistant, porous titanium oxide structure), which can effectively promote the integration with the bone; the implant produced by the Swiss Straumann Company has been treated on its surface SLA (large-particle acid-etched sandblasting) treatment, and further upgraded SLActive (act...
