Too many cases of dental restoration after dental restoration, dental infection, dental infection of materials, unstable sterilization of equipment, inflammation after tooth restoration or dental restoration due to tooth decay It is a natural result obtained by using the conventional dental caries restorative (10) having no or less sterilization power.

On the other hand, tooth decay is a disease that occurs when a combination of host and pathogen factors and environmental factors act simultaneously. Among the various bacteria, mutans is the leading cause of tooth decay (dental caries). Acts as a pathogen.

Whatever food you eat, tooth decay does not occur in the teeth of animals that do not have mutans in the oral cavity.

In the oral cavity of a child raised by a mother who has a lot of S. mu tans in the oral cavity, a relatively large number of caries will occur.

In addition, the decay rate of tooth decay varies depending on the stickiness of food, the shape, location, and arrangement of the tooth. The decay occurs in the form of very fine white spots at first, and gradually turns into brown spots, and its size increases and deepens. There are many theories about the cause of tooth decay and tooth decay, but the theory that acid produced by microorganisms in the oral cavity decomposes food destroys tooth tissue and causes tooth decay. There are many important factors that affect the development of dental caries.

In particular, sugar in food is a component that causes tooth decay, and sugar in food is easily fermented inside the plaque to produce acids, and makes very sticky glycoproteins so that the bacterium adheres firmly to the back. Help and limit the acid from being washed away by saliva.

In addition to sugar, carbohydrates such as starch, fructose and glucose in cooked foods are also easily fermented to produce acids, which is a major cause of tooth decay.

As such, the number of times and the timing of ingestion of foods containing fermented carbohydrates have a great effect on caries.

Vitalium Cobalt and chromium alloys used primarily for dental surgery and introduced in the early 1930s. Strength is similar to type 4 (hard) gold alloys and hardness is higher than gold alloys.

Casting temperature is higher than gold alloy, high frequency induction actuator is required

The casting shrinkage is large and the elastic modulus is about twice as strong as the gold alloy.

Titanium and Titanium Alloys: Used as implants, self-threading pins, orthodontic materials (Ni-Mo alloys), showing steady growth birds and difficult to cast and are not used for fabricating restorations that require precision.

Its advantages are high corrosion resistance, high strength, and good biocompatibility, but it has the disadvantage of low density and elastic modulus and is widely used in the medical industry.

 In the above, the metal or alloy, which is the material of the restorative material of the dental inlay or onlay of the present invention, has been described in detail. The dental restorative material uses gold or platinum most of the metal and the metal complements the disadvantages of the resin. Semi-permanent, less discoloration and secondary tooth decay and metal is the most physically and biologically excellent material, but as a material for filling teeth, metal is a part of the body that is not toxic to the human body. The metal used is gold or platinum as above. Resin is the resin that fills the tooth color when there is little tooth decay. Inlay is the metal when the tooth is too big to be filled with the resin. Say stuffing up.

If so, the following describes the gold (gold) most used among the metal as an example.

If the content of pure gold in the alloy is 15 to 39% by weight or less, it is called b type. If the content of gold is 40 to 45% by weight, it is a type. It is referred to as about 100 wt% platinum (pt).

In addition, porcelain gold is about 70 to 80% by weight of pure gold in the alloy, and contains other components to melt at a high temperature is more expensive than ordinary pure gold.

In lay gold also uses 80 to 85% by weight of pure gold in the alloy due to its precision. (In lay is usually one kind.)

In general, a high gold content in dentistry means gold that has already been produced, and is not made individually by adding other ingredients to gold.

In other words, a higher gold content in inlay means that pt (white poultry) is the most similar to a tooth. Nickel cobalt is selected as the non-noble metal.

In case of on lay, the tooth is removed and the tooth is removed for a certain holding force, and then the impression is obtained using the impression material (alginate) on the cavities. .

The gold content of crown gold alloys is of several grades, and pure gold can't be backed out, so alloys are made to match the hardness of teeth.

The most expensive gold alloy in dentistry is pure gold + platinum and the next level is pure gold + various non-noble metals.

 At this stage, there are usually four or five types of dental alloy companies that produce them, and one dentist usually uses platinum alloys and one or two common gold alloys.

Resin used instead of metal is put into the oral cavity through the polymerization process outside the oral cavity, so it undergoes less shrinkage and precise process, but since the resin bonding system itself is mostly resin-based cement, the above-mentioned fine leakage possibility remains.

Especially in the case of resin in lay, you may not know that there is a caries inside, so you can see a great loss of caries later.

The likelihood of caries recurrence is low if complete cavities are completely removed and cleaned, and amalgam may be said to be better than resin in lay because of the anti-carious activity of the material itself. Some corrosion occurs and this corrosive component is present between the tooth and the metal, which acts as a bacteriostatic function, but it can cause mercury poisoning if it is not used to soften mercury. have.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

According to the method (100) and there are many types and methods of plating 100, all of them cannot be listed, and thus, electroplating will be described as an exemplary embodiment.

 Coating or plating 100 is generally divided into electroplating and electroless plating, and silver plating requires a solution containing silver ions, and gold plating requires a solution containing gold nano ions.

  When the electrode is placed in a solution containing metal ions and a current is applied, metal ions are discharged and precipitated at the cathode, which is used to form a thin film of metal on the surface of the article placed on the cathode.

Although the purpose of plating 100 is to finish beautifully, to increase acid resistance in corrosion resistance, to resist abrasion, and to obtain other necessary surface properties, the present invention provides an onlay which is a restoration material to be injected into the oral cavity of a human body. This is to increase antimicrobial activity on lay).

 The general sequence of the electroplating of the on lay, the restorative material of the present invention is plated with nickel so as to coat the metal surface with copper (270) and secondly, silver nano (20) plating (100). This process may be omitted if necessary, and finally, the silver nano 20 is plated.

 The on tank, which is the restorative material, is stored in a container that accommodates the on lay, which is the restoration material to be plated with silver nano 20, in the plating tank 260, and the on lay, which is the restorative material on the pole side. And the silver nanoplate 320 which is solidified is connected to the pole side, and the silver nano (20) solution 20 containing the restorative agent (10) and the silver nano (20) ions is injected and +,- DC current flows to the pole and gradually the onlay (relay 10) becomes the silver nano (20) coating 100 and the coated or plated (100) silver nano (20) restorative onlay ( on lay) once again through the washing process 230 is dried (160) to complete (380).

As described above, an on-lay restorative material 10, which is an object metal to be plated (100), is attached to the negative electrode of the battery, and a silver nano 20 plate 320 is attached to the positive electrode so that the positive and negative ions of the silver fall. Here, the electrons go to the on-lay which is the metal restorative material 10 which is the pole, and of course, the aqueous solution contains the silver nano 20 ions 20. When the electrons come to the pole, the repair material 10 is onlay. Silver nano (20) ions (20) in the aqueous solution is attached to the (on lay) around the silver nano (20) wet plating.

  The thickness of the coating (100) of the silver nano (20) wet plating is the coating (100) to a thickness of 0.0l㎛ ~ 50㎛ (micrometer) of the metal restorative material (10) of the on-lay (on lay) alloy In a preferred weight ratio of 0.01 to 20% by weight in total. The silver nano 20 particles have a particle size of 0.05 to 300 nm, and the silver nano 20 per 100 g of the metal restorative weight in PPM units may be plated 100 at a PPM content ratio of 0.01 to 20 PPM.

In addition, the embodiment of the silver nano 20 plating 100 is characterized by following the conventional silver plating, method and using a plating material as the aged silver nano 20 material.

Next, the silver nano 20 plasma coating process 100, which is a dry plating method of on lay, which is a metal restoration containing silver nano 20, is as follows.

First, a brief look at plasma,

Plasma is a gaseous state that is separated into electrons with positive charges and positively charged ions at high temperatures, and has a high degree of charge separation but is neutral because of the same number of positive and positive charges.

  Since the long-acting Coulomb force acts between charges, it is characterized by the collective action of the whole moving under the influence of the distant state rather than the local state of the short distance. In 1928, I. Langmuer, USA, first applied the concept of plasma to ionized gases produced during electrical discharges.

 The high temperature and vigorous chemical properties of the plasma provide extreme environments that are difficult to obtain by conventional methods and can be used to give new physical and chemical properties different from the body by changing the properties of the synthesis of new materials and the surface of metals and polymers.
