The present invention relates to a composite resin or cement, which is a dental caries make containing silver nano, which has antibacterial ability, as described above, and to a material of a dental restoration made of resin. 0.01 to 20% by weight of the silver nano (140) relates to a functional caries make (dental caries make) having the effect of anti-bacterial power, far-infrared radiation, silver ion release.

After dental restoration at the dentist, inflammation occurs after tooth decay due to contamination of sterilized parts of dental caries, bacterial infection of materials, unsafe sterilization of instruments, etc. This is a natural result obtained by using a conventional dental caries restorative or insignificant.

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.

Tooth decay has a high probability of tooth decay, depending on the stickiness of food, the shape, location, and arrangement of the tooth. There are many theories about the cause of tooth decay, but the theory that the acid produced by microorganisms in the oral cavity breaks down and destroys the tissues of the tooth causes tooth decay. There are several 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 plaque. 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.

The present invention relates to a dental caries make containing silver nano-antibacterial as described above, in which the silver nano 20 is 0.01 to 20% by weight of PPM in the composite resin. It is about dental caries make excellent antibacterial and bactericidal power (140) put into the 0.01 to 20PPM reference range per sugar.

If so, look at the composite resin (dental caries make) to help the understanding of the present invention

Composite resins are rosin, which is industrially known as resin, and dental resins are white with tooth color and are a mechanism that adheres to the tooth surface. Amalgam is just a filling method, and there is a difference between a suit and amalgam.

There is no connection between composite resin and neurotherapy, which is rarely the case when resin is bonded to the tooth surface, but the harmful component of the resin is a fine tube called the dentin tube on the dentin surface of the tooth. It can penetrate into the inner nerve and cause pulp necrosis.

Inlay or on lay of a composite resin to repair the cavities, or to remove the cavities, to form a dental model by shaping the bone with the restorative material, and then to create a filling on the model. Repair is a way to treat tooth decay.

In particular, when women are laughing or talking, they can see bad materials such as metal or amalgam treatment in their mouths, and there are some parts that are unsightly. In this case, composite resins can make teeth look very good. Inlay or on lay restoration is the best way to reproduce the color and shape of the teeth.

As described above, the above materials used in the restoration or inlay or on lay procedure have advantages and disadvantages, and thus can be widely used according to the age group of the cavities and the economic conditions.

 In order to help the understanding of the present invention will be described in detail the silver and silver nano (20) constituents of the present invention.

    Nanotechnology is a technology that identifies and controls substances at the molecular and atomic levels.It comes from the Greek word dwarf, lanose, and 1 nanometer 'corresponds to one-tenth of the thickness of the hair. It is made of silver solution (colloid), which is a chemical decomposition method or a fine particle state in nano units, and is widely used in industrial fields.

Silver, the main ingredient of Nano silver, has been recognized as a precious metal of high value from ancient times, and has been the object of collection, and it is recognized as an important industrial material in modern industry as well as its value as money. The production of silver is proportional to the production of gold in many ways.

Silver was mined early in Europe's Mediterranean coast, where silver was produced from the Incas and Aztecs before the discovery of the Americas, and then silver from Peru and Bolivia entered Europe and flowed out from 1520 to 1800.

It has grown steadily, but has declined since the discovery of large amounts of silver in the early 19th century.

Currently, the world's major silver producers are Russia (13.8%), Canada (13.5%), Mexico (13%), Peru (13%), United States (11%), Australia (8%), Poland (6%). The country's silver reserves are 17 million tons, and its mining capacity is about 1.2 million tons. As of 2002, silver produced in Korea is about 5,000 kg, which accounts for 1.2% of the total domestic demand. The amount is so small that the rest of the silver is imported from abroad.

Characteristics of silver: The color of silver is gray in the case of elegant gray-white metal or powder, specific gravity is 10-12, Mohs hardness is 2.5-3, melting point 280 is 960.5 ℃.

In particular, the melting point (280) of silver is very important for the temperature compensation of high thermometers, and it is the standard of scientific and industrial temperature. Silver is the best conductor of metal, and is used comprehensively for mechanical contacts and other electronics. .

Silver is optically 90% of visible light, which is one of the best metals such as platinum, and silver does not rust even when left in the air or heated (190), but it reacts with sulfur and hydrogen sulfide to emulsify it. Silver is made and turns black.

     In addition, the mechanical properties change according to the amount of impurities (O₂) contained in the silver, and the hardness of the high-purity silver obtained by thermal annealing is Brinell hardness HBS (10/500) 25-27, tensile strength 12-16kgf / mm2. The cast strength of the cast was up to about 29 kgf / mm 2, the combustion rate was 48 to 54%, and the recrystallization temperature was 150 ° C.

    Particularly, in the case of pure silver, the processed hardened material is softened by recrystallization at normal room temperature (400), and the malleability and flexibility are abundant next to gold.

     The effect of silver has been used as a tool to check the imbalance of the body that one cannot feel because the gloss or color changes depending on the condition of the body when worn on the body from ancient times. This fatigue or low rhythm), Dongbobogam said that it is effective in the prevention and treatment of mental disorders and women's diseases such as epilepsy and game. The five chapters are said to be comfortable, the mind and body are stabilized, and the main body records that the body is lengthened by chasing morale and lightening the body.

      Also, when the Black Plague prevailed in the Middle Ages, nobility of the black aristocrats and royals, who had many silverware and silver utensils, did not have black plague, which released silver to the extent that it was able to sterilize the Black Plague bacteria, making it relatively safe from infectious diseases. In the place where the royal family and the state guests were served, silver products were used habitually.

In order to help the understanding of the silver nano 20, the present invention will be described briefly with respect to the silver nano (20) (Nano silver) extraction method and features.

The atomic weight of silver is 107.87 amu and the fact that silver (Ag) is bactericidal has been known for a long time.

Silver nano (20) was first developed by a biotechnology company, a government-affiliated organization in our country, and was named silver nano (20) as a compound name of the brand name Na no to technology and silver. ;

  Silver nano (20) is a field of Na no to technology (nano technology) is an advanced antimicrobial agent using a mechanism of strong antibacterial and sterilization function, electromagnetic shielding excellent electrical conductivity. Silver nano (20) is unlikely to be resistant to bacteria, unlike conventional antibiotics. Silver nano (20) has been shown to kill almost all single cell germs on the ground in a short time. .

 Currently, a variety of products based on silver nano (20) consisting of powder and solution have been invented and commercialized and produced in real life. This technology, called silver nano (20), converts silver to nanometers (1 billion won). It is a small particle size of 1m / min), that is, 0,000000001m. If one gram of silver is aged, ten particles can be produced.

Therefore, silver silver (Age) is a new concept that is made by using excellent effects such as anti-bacterial, deodorizing power, and extended food preservation time among many characteristics of silver. .

 Since ancient times, silver has been recognized as a disinfecting substance that not only prevents bacteria but also disinfects the East and West. Currently, the extraction method of silver (20) (Nano silver) which is currently used adds silver (Age 99.9%) to distilled water. After generating low current at low temperature, electrolyzing compounds containing silver and conducting electrophoresis using + and-pole of each molecule, silver (Age 99.9%) can be collected. In addition, liquid reduction method, grinding It can be manufactured by a physical method such as) and in order to obtain a stable silver nano (20) (Nano silver), the above electrolysis method is used a lot.

Silver ions are also used in general sterilization concept machines and disinfectants, and all silver products currently used are silver obtained by decomposition, and the sterilization power of silver varies depending on the product, but can obtain up to 99%.

 The silver nanoparticles of the present invention are silver microparticles having a particle size of 0.05 to 300 nm, which directly act on harmful bacteria, directly dissolve the cell membranes of harmful bacteria, and disrupt the electron transfer system of harmful bacteria. As a result, it has a certain antibacterial and antibacterial activity (99.9%). (The virus size is about 10nm.)

     The main antimicrobial mechanism of silver nano (20) is to dissolve harmful bacteria cell membranes and interact with enzymes in the cells to block the metabolic function of nutrients, ie, the influx and discharge of nutrients, and to stop the respiratory function and production of harmful bacteria. And destroys regenerating ability to kill harmful bacteria.

     In addition, the silver nano (20) by controlling the harmful bacteria by releasing the antimicrobial power continuously from the fine particles is excellent in the antimicrobial, antimicrobial sustainability.

Therefore, silver nano (20) does not produce resistance and silver nano (20) has a surface reaction is effective and can kill all 99% of the bacteria, and particularly effective in the general E. coli or food poisoning.

   The smaller the nanoparticles, the better the bactericidal and antimicrobial activity. Based on the experimental data so far, Escherichia coli, Staphylococcus aureus, Salmonella, Vibrio bacillus, Heterogeneous bacteria, Pneumococcus, Typhoid bacillus and the most resistant MRSA Resistant Staphylococcus aureus) can be 99.9% antibacterial and sterilized.

     Even if silver exists in an ionic state or a metal state, it can be referred to as colloidal silver if it exists in a colloidal state by a solvent.

In silver nano (20) (Nano silver) is the best antibacterial silver nano particles (20) minimized.

   In addition, unlike the general chemical antibacterial or chlorine disinfectant, silver nano (20) is a pure silver ultra fine particle, has excellent antibacterial and bactericidal zone (99.9%) even at high temperature, non-toxic and non-irritating to the human body, bacteria and E. coli virus fungus It has been reported that bacteria cannot live in contact with silver nano 20 for more than 5 minutes.

The present invention, as described above, by putting the silver nano (20) solution or powder into the dental caries make (dental caries make) or restorative inlay (on lay) or on the restorative material made of the above various materials (140) It relates to dental caries make, a functional composite resin containing silver nano (20) for anti-sterilizing and releasing harmful substances and releasing healthy ions and far infrared rays.

Resin has the advantages of ease of use, economical and low tooth removal compared to ceramic dental prosthesis, while discoloration and shorter life than ceramic.

There are many kinds of dental resins, and physical strength, adhesion, and aesthetics vary widely depending on the type of resin. The cost of dental plastic surgery using resin varies depending on the resin used and the ability of the dentist to perform the procedure.

Recently developed resin kits provide resins of various purposes and colors, which play an important role in the practice of dental implants closer to natural teeth. Resin is used for tooth decay, small injuries and gaps in the incisors. It is a good way to use.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing each of the drawings, the same reference numerals refer to the same reference numerals and components even though they are shown in different drawings.
