Abstract

The invention belongs to the technical field of ceramic teeth, and relates to a high-strength and high-hardness ceramic gum abutment. The ceramic gum abutment is prepared from, by weight, 90 to 110 parts of zirconium oxide powder, 60-90 parts of titanium dioxide, 20 to 50 parts of aluminum oxide fibers, 0.2 to 1.0 part of ferric oxide, 0.1 to 2.0 parts of a dispersant, 20 to 50 parts of light-cured resin, 0.1 to 0.5 part of a photoinitiator, 0.1 to 3.0 parts of an adhesive, 0.5 to 5.0 parts of a coloring agent, 0.5 to 1.0 part of a pore-forming agent and 500 parts of a solvent; and the particle size of the zirconium oxide powder ranges from 100 nm to 500 nm, the particle size of the titanium dioxide ranges from 400 nm to 1000 nm, the diameter of the aluminum oxide fibers ranges from 50 nmto 200 nm, and the length of the aluminum oxide fibers ranges from 10 [mu]m to 200 [mu]m. According to the high-strength and high-hardness ceramic gum abutment, the surface of the ceramic gum abutmentis pure white and free of metallic luster, the surface is free of cracks in the machining process, the service life of the gum abutment is long, and safety is good.

Description

technical field [0001] The invention belongs to the technical field of ceramic teeth, and in particular relates to a high-strength and high-hardness ceramic gum abutment. Background technique [0002] Dental implants are composed of multiple parts, including implants, abutments, dentures, etc., where the abutment is installed on the implant platform anchored in the bone and extends into the oral cavity for linking, supporting and Fixed restoration or implant superstructure; the abutment usually obtains the ability of retention, anti-torsion and positioning through the inner abutment link or outer abutment link structure. [0003] The gum abutment in the prior art should not only have good biocompatibility, safety and functionality, but also need to have chemical stability and corrosion resistance; the existing gum abutment usually adopts cast gold alloy, which has high hardness , it is convenient to fix implants and dentures during tooth restoration, but this type of alloy ...
