る。In order to give an ivory color of ivory color excellent in corrosion resistance to dental materials such as dental brackets and steel wires, single metal plating has various difficulties. It is advantageous to apply plating. It is necessary to select gold, platinum, silver, palladium, rhodium, etc., which belong to the noble metals, as the component elements of the alloy plating that have excellent corrosion resistance and do not adversely affect the human body. Gold has a golden color tone, and platinum, silver, palladium, rhodium, etc. have a white color tone. Therefore, in order to perform plating with an ivory-colored aesthetic tone, gold and platinum, silver, palladium, etc. are used for alloy plating of two or more elements, and the content ratio of gold in the alloy plating deposit is reduced. By doing so, the golden color is thinned and a plating deposition film having an ivory color tone is obtained.

Alloy plating was performed using a ternary alloy plating solution containing gold, platinum, and palladium. However, it is difficult to freely change the ratio of binary alloys such as gold and platinum or ternary alloys such as gold, platinum and silver, and the color tone of the obtained alloy plating deposition film is not satisfactory as an ivory color. Nakatsuta. It is considered that this is due to the difference in the plating deposition potential of the metal and the electrochemical equivalent of the metal in the alloy plating solution.

Single-layer metal plating such as gold and palladium, gold and platinum and silver, gold and platinum and palladium, etc. in sequence (that is, 2 layers plating for gold and platinum, 3 layers plating for gold, platinum and silver) Then, thermal diffusion is performed at a heating temperature of 200 to 600 ° C. to form a binary alloy or a ternary alloy. In this method, plating of each single metal is sequentially performed by a usual method.

つた。As shown in FIG. 1, the above-mentioned electroplating was used to prepare a three-layered dental material having a silver plating film thickness of 0.60 μm, a platinum plating film thickness of 1.60 μm, and a gold plating film thickness of 1.00 μm. , Heating temperature 500 in non-oxidizing atmosphere
As a result of heating at 0 ° C. for 10 minutes, the silver, platinum, and gold plating layers mutually thermally diffused, resulting in silver-platinum-gold ternary alloy plating. As a result of analyzing the alloy ratio (wt%) of the ternary alloy plating, it was found that gold was 32.2%, platinum was 57.3%, and silver was 10.5%.

れない。The reason for setting the silver content to 10% is to obtain an ivory color tone without impairing the corrosion resistance. The content of silver in the ternary alloy is in the range of 10 ± 2%, and when the content of silver is 15% or more, when used in an orthodontic patient, the color changes to black in about half a month. When the silver content is 6% or less, the corrosion resistance is good, but the ivory color tone cannot be obtained.

同一の審美的色調が得られた。A gold content of 32 ± 3% is convenient for obtaining an ivory color tone. Gold content is 32 ± 3%
When it is more than the range of 1, the golden color becomes richer as it increases, and when the content of gold is less than the range of 32 ± 3%, it becomes white as it decreases, and in any case, an ivory color tone is obtained. It is not possible. In addition, if palladium or rhodium (with the same content ratio) is used in place of platinum in the ternary alloy, a dull gray ivory color is obtained in the case of palladium, and alloying by thermal diffusion is long in the case of rhodium. It just takes time and you can't get an ivory color. For the above reasons, in the present invention, the aesthetic color tone which is almost the same as the ivory color of human teeth is obtained by plating the dental material with the ternary alloy of gold, platinum and silver.

ことが判りにくいほどである。As a result of using the above-mentioned dental material for an orthodontic patient, the color tone of the ternary alloy-plated dental material of the example is similar to that of a human tooth. It's hard to find out.

Since saliva is weakly acidic in addition to food residue remaining in the human mouth, the dental material may turn black due to the food residue and saliva. Further, when the plating film is worn away by brushing teeth, the raw material stainless steel may be exposed.

Neither the discoloration of the dental material became black nor the alloy plating layer of the dental material was worn or peeled off due to tooth brushing and the stainless steel substrate was exposed.
