Abstract

The invention relates to an alloy material for a false tooth. The alloy material comprises the following components in percentage by weight: 58.00-63.00% of Co, 22.00-26% of Cr, 6.00-10.00% of W, 2.30-2.80% of Mo, 0.80-1.10% of Nb, 0.80-1.10% of Mn, 0.80-1.10% of Si and 0.80-1.10% of Fe. According to the alloy material for the false tooth, cobalt-chromium alloy is used, noble material which is high in using price is not used, Be element which is harmful to a human body is abandoned, and the cobalt-chromium alloy prepared from Co, Cr, W, Mo, Nb, Mn, Si and Fe low in price and safe and nontoxic is low in cost, safe and nontoxic, strong in corrosion resistance, high in strength of extension, low in coefficient of linear expansion, large in hardness and yield strength. The alloy material for the false tooth provided by the invention is an excellent material for making ceramic teeth.

Description

technical field [0001] The invention relates to the field of dental restoration, in particular to denture alloy materials. Background technique [0002] Dental disease is a common disease with a high incidence. Tooth defects and missing dentition are very common in dental diseases, and dentures are usually used to restore them. [0003] Porcelain teeth are a kind of commonly used dentures. Generally, alloy materials are used to make porcelain teeth. The alloy for making porcelain teeth must meet the following conditions: (1) good biocompatibility, non-toxic and harmless to the human body; (2) chemical Stable performance, must have excellent oxidation resistance and corrosion resistance; (3) stable physical properties, must have high strength. [0004] General porcelain teeth are divided into precious metal porcelain teeth and non-precious metal porcelain teeth. Precious metal porcelain teeth are the best performance porcelain teeth. Taking gold porcelain teeth as an exampl...
