Abstract
The invention discloses a composite dental alloy. The invention belongs to the field of alloy material preparation. The composite dental alloy is characterized by comprising the following components in percentage mass: 60-70% of Co, 20-30% of doped Cr and 10-15% of Mo. The alloy is prepared from non-noble metal and noble metal alloy, and has favorable biocompatibility.
Description
Technical field:
The invention belongs to the alloy material preparation field, relate in particular to the dental alloy preparation field.
Background technology:
Alloy is the mixture of 2 kinds or two or more metal, and dental alloy comprises at least 4 kinds of metals usually, even more than 6 kinds.Most of alloys are to take gold as principal element, and palladium, silver, nickel, cobalt and titanium are also arranged, and the minor element kind is more, and the element in the periodic table of elements more than 25 kinds all can be used for dental alloy.The dental casting alloy directly is placed in oral cavity, requires to have good biocompatibility.But alloy is the meeting corrosion under the effect of body fluid, the tissue reaction that causes toxicity.In existing dental casting alloy, high precious metal and the precious metal alloys biocompatibility of phase structure are best.But high precious metal and precious metal alloys are expensive.Therefore, wish that non-high precious metal and precious metal alloys manufacture, the dental material of good biocompatibility.
The objective of the invention is to design that a kind of non-high precious metal and precious metal alloys manufacture, the dental material of good biocompatibility.
Technical scheme of the present invention is: a kind of compound dental alloy is characterized in that: according to mass ratio, described dental alloy is by 60～70%Co, and 20～30%Cr and 10～15%Mo adulterate.
The invention has the beneficial effects as follows:
Non-high precious metal and precious metal alloys are manufactured, and cytotoxicity is little, the dental material of good biocompatibility.
The specific embodiment of the invention:
Embodiment 1: according to mass ratio, described dental alloy is by 65%Co, and 20%Cr and 15%Mo adulterate.
Embodiment 2: according to mass ratio, described dental alloy is by 70%Co, and 20%Cr and 10%Mo adulterate.
Claims (2)
1. a compound dental alloy, it is characterized in that: according to mass ratio, described dental alloy is by 60～70%Co, and 20～30%Cr and 10～15%Mo adulterate.
2. a kind of compound dental alloy according to claim 1 is characterized in that: according to mass ratio, described dental alloy is by 70%Co, doping 30%Cr and 15%Mo.
