Embodiment Construction

[0025] Hereinafter, the present invention will be described in detail with reference to embodiments. However, the present invention is not limited to the following embodiments, and may be embodied in various other forms, and these embodiments are provided to complete the disclosure of the present invention and to fully inform those skilled in the art of the scope of the present invention.

[0026] In the embodiment of the present invention, weight% (wt%) is the weight percentage of the component based on the total weight of the entire alloy. Regarding the range for weight %, when the expression "greater than or less than" is used, the boundary value of the set range is not included, and when only the expression "range" is used, or the expression "equal to or greater than, or equal to or less than" is used, Include the boundary value of the range.

[0027] In the embodiments of the present invention, unavoidable impurities may refer to typical impurities that may be unintentionally...

Abstract

Metal alloys for dental porcelain fusing and dental prosthetic appliances are provided. The metal alloy includes: gold (Au) in an amount that is greater than 0 and equal to or smaller than 35 weight %; silver (Ag) in an amount of 5 to 35 weight %; indium (In) in an amount of 6 to 40 weight %; palladium (Pd) in an amount of 30 to 70 weight %; and at least one element selected from the group consisting of boron (B), germanium (Ge), zirconium (Zr), silicon (Si) and iron (Fe) in a total amount that is greater than 0 and equal to or smaller than 5.0 weight %.

Description

Technical field [0001] The present invention relates to a metal alloy, and more particularly to a metal alloy for dental porcelain fusing used in a prosthetic appliance in dental clinics and a dental prosthetic device using the metal alloy. Background technique [0002] The metal alloy for dental porcelain fusion is used in the oral cavity where various environmental changes such as temperature, acidity, and pressure in the human body occur. Therefore, they not only require excellent mechanical properties, but also chemical stability and aesthetics. For example, since metal alloys for dental porcelain fusion are used in the oral cavity, they should not corrode or discolor, nor should they be harmful to the human body. In addition, since the metal alloys for fusing the dental porcelain material withstand the pressure caused by chewing food, they need to have high mechanical properties. [0003] From this point of view, gold-based alloys with high gold content are widely used for f...
