Abstract
A soft steel alloy material for dentistry belongs to the technical field of dentistry materials. Chemical elements and weight percentages of the soft steel alloy material include 65%-70% of nickel, 8%-10% of chromium, 5%-6% of copper, 3.5%-5.5% of tin, 3.5%-4.5% of molybdenum, 2.5%-3.5% of titanium, 2%-3% of silicon, 1.5%-2% of iron, 1.0%-1.3% of manganese and 1.0%-1.2% of carbon. The soft steel alloy material provided by the technical scheme of the invention is fine in biocompatibility with human bodies, has fine corrosion resistance, has hemolysis rate lower than 5%, does not have acute systemic toxicity, has cytotoxicity which is not higher than I level, and does not have oral mucous membrane irritation or delayed contact sensitization, and then the soft steel alloy material has perfect safety. In addition, because the soft steel alloy material has 589.4-696.7 tensile strength ob(MPa), 4.34-4.05 elongation (%) and 342-392 Vickers hardness, the soft steel alloy material has appropriate strength, hardness and wear resistance and fine processing property, and can be adaptable to soft and hard tissue inside orals.
Description
Technical field
The invention belongs to the dental material technical field, be specifically related to a kind of soft steel alloy material for dentistry.
Background technology
Soft steel alloy material for dentistry is used to make hat that tooth section fixed, the repaired usefulness bridge of coming of age, and is a kind of in the biomedical metal material.As the industry's knowledge of the reason, the security requirement of dental material is very harsh, because the dental material goods place the oral cavity for a long time, directly contact with tissue, so except requiring have the good affinity with tissue, the sensitization of its hemolysis rate for human body, acute general toxicity, cytotoxicity, oral mucosa stimulation, skin and mucous membrane all must meet the human body requirement.Validity to dental material requires equally very harsh simultaneously, because when people take food, tooth removes laboratory rodent chow, often outside various acidity of contact and the alkaline matter, also be in the environment of mouth cavity liquid for a long time, therefore dental material not only must be nontoxic to human body, also must have high corrosion resistance, suitable intensity, hardness and wear resistance, can adapt to intraoral soft or hard tissue and good workability.
With metallic substance security (biocompatibility) and validity (physicals of alloy) there is unusual technical requirements just because of the tooth section that comprises soft steel alloy material for dentistry, therefore up to now China except Shanghai dental materal factory production has dental Ni-chromium-Fe forged alloy, not have manufacturer and set foot in this field, the U.S. is also only arranged in the world, Germany, Japan and Switzerland four countries make, and Japan has Harbin thousand high post in Chinese Harbin in the individual proprietorship mode and reaches medicine equipment company limited, produce aforesaid soft steel alloy material for dentistry＜enterprise's production licence number: the production of black food medicine prison tool is permitted No. 20080135, equipment registration card number: No. the 2630020th, black food medicine prison tool (standard) word 2008 〉.Soft steel alloy material for dentistry with international top-brand has the Vitallium of the U.S., Bayer, the BEGO of Germany, and the Wironit soft steel alloy material for dentistry in the wherein German BEGO brand is internationally recognized reputable brand.But, perhaps consider for occupying property (monopoly) technical confidentiality and market, in existing domestic and foreign literature, there is no the report of all relevant soft steel alloy material for dentistry, therefore present present situation: make hat that tooth section uses in artificial tooth manufacturing company of the thousands of family of more particularly China that China market was seen in and come of age the used mild steel of bridge by Germany, Japan, the U.S. and Switzerland occupy absolute dominant position, though the tooth section that the Chinese Shanghai dental materal factory is produced can say it also is very outstanding with mild steel, the soft steel alloy material for dentistry that is not enough to be produced with aforementioned country is competed on market.Though the tooth section that aforementioned country produced costs an arm and a leg with the mild steel alloy product, but because of its excellent property, good looking appearance, so be subjected to hospital, artificial tooth manufacturing company and patient's welcome, the share in market rises year by year, flourishing cities such as picture Beijing, Shanghai select for use external product to replace domestic brand fully mostly.In view of this, from the autonomous angle of industry, must develop have meet human safety, use properties is good and be easy to process, the homemade soft steel alloy material for dentistry of good looking appearance, break away from soft steel alloy material for dentistry simultaneously to the absolute dependence of import with satisfy the cheapness that the odontopathy patient enjoys odontotherapy, technical scheme described below produces under this background.
Summary of the invention
Task of the present invention is to provide a kind of soft steel alloy material for dentistry that had not only had the ideal security but also had excellent physicals for human body.
Task of the present invention is finished like this, a kind of soft steel alloy material for dentistry, its chemical element and weight percent are: nickel 65%-70%, chromium 8%-10%, copper 5%-6%, tin 3.5%-5.5%, molybdenum 3.5%-4.5%, titanium 2.5%-3.5%, silicon 2%-3%, iron 1.5%-2%, manganese 1.0%-1.3% and carbon 1.0%-1.2%.
The soft steel alloy material for dentistry that technical solution of the present invention provides because have with the good biocompatibility of human body, have excellent corrosion resisting performance, hemolysis rate＜5%, do not have acute general toxicity, cytotoxicity is not more than the I level, no oral mucosa stimulation and do not have tardy property contact sensitivity response, thereby has the ideal security; Because tensile strength sigma
b(MPa) can reach 589.4-696.7, unit elongation (%) can reach 4.34-5.05 and Vickers' hardness (HV) 342-392, thereby has suitable intensity, hardness, wear resistance and good processability, can adapt to intraoral soft or hard tissue.
