Problems solved by technology

[0003] At present, the zirconia ceramic teeth that can be produced are all single milky white in color, while human teeth are slightly yellow and gradually become darker from the crown to the root. Therefore, if a single milky white denture is used, it will be different from the original The color difference of the teeth is too obvious, which is extremely unsightly, and it is easy to identify with the naked eye, and the fracture toughness of the existing nano-zirconia composite ceramic teeth still needs to be further improved. It is particularly important that tough nano-zirconia meets ceramic teeth, and no relevant patent literature reports have been found through searching.

Abstract

The invention relates to a nanometer zirconium oxide composite ceramic material, a tooth color-imitating nanometer zirconium oxide composite ceramic tooth and a preparation method thereof and belongs to the technical field of zirconium oxide composite ceramic teeth. The nanometer zirconium oxide composite ceramic material comprises the following raw materials in parts by mass: 90-100 parts of nanometer zirconium oxide and 10-80 parts of organically synthesized colloid, wherein the organically synthesized colloid comprises the following raw materials in parts by mass: 10-50 parts of paraffin, 10-30 parts of polyethylene, 10-30 parts of polypropylene, 1-5 parts of stearic acid and 1-5 parts of oleic acid. The nanometer zirconium oxide composite ceramic material provided by the invention has a good mechanical property, excellent air permeability, strong chemical stability and excellent biocompatibility. The bending strength of the prepared ceramic tooth can reach 1200MPa, and the breaking tenacity can reach 9MN / m<3 / 2>. The tooth is extremely high in biofidelity and the color difference of the tooth with a human tooth is in a range of + / -1 chromatic degree.

Description

technical field [0001] The invention belongs to the technical field of zirconia ceramic teeth for oral restoration, and in particular relates to a nano-zirconia composite ceramic material, a tooth-colored nano-zirconia composite ceramic tooth and a preparation method thereof. Background technique [0002] Nano zirconia composite ceramic material is an excellent high-tech biomaterial. It has good mechanical properties, excellent ventilation performance, strong chemical stability, and excellent biocompatibility, and is superior to various metal alloys, including gold. Nano-composite zirconia ceramics are non-irritating and non-allergic to the gums, and avoid adverse reactions such as allergies, irritations, and corrosion caused by metals in the oral cavity. It can greatly meet the aesthetic requirements of oral restoration and perfectly reproduce the effect of natural teeth. Therefore, from the perspective of the market demand of the dental medical industry, nano-composite zi...
