The purpose of these dental substrates is to artificially restore the condition of the teeth as they are, and it is left to the natural progress with respect to the occurrence of tooth decay and the deterioration of gingivitis. Therefore, the present invention aims to improve salivary properties after dental treatment and positively prevent the progress of tooth decay and gingivitis in the future. [Structure] The dental base material according to the present invention contains divalent and trivalent iron salts in its material. When a material containing divalent and trivalent iron salts is put into water or saliva, the water and saliva are transformed into water in which 2 × 10 ⁻¹² mol of divalent and trivalent iron salts are induced, that is, “active water”, It transforms saliva into a weakly alkaline solution, and completely kills alveolar pyorrhea such as cavities such as Streptococcus mutans and Streptococcus gingivalis.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dental base material constituting a denture, an inlay, a mouthpiece, etc., and more particularly to a material structure for improving saliva properties after treatment.

[0002]

[Prior art]

 Various base materials used for dental treatment include those that restore the condition of teeth and those that force the dentition, and these can all be understood as those that are placed in the oral cavity and handled.

[0003] For example, fillers such as inlays for treating dental caries (caries), crowns, dentures for filling missing teeth, bridges, implants, etc. are used to restore the condition of teeth, and the dentition is forced. There is what is called a dental mouthpiece. In addition, since the treatment instruments used by the treatment staff, such as reamers, vacuums, mirrors, etc., are also used by putting them in the oral cavity, the concept of the "base material" according to the present invention includes these equipments.

Conventionally, these dental substrates are made of materials that are chemically resistant and durable and that are harmless to the human body. For example, in the case of dentures, silver or gold is used in the case of resin, ceramic, or crown of jacket crown. Cement is used as the adhesive for the inlay and crown, and metal materials that are resistant to the high heat during sterilization are used for hand instruments such as mirrors.

[Problems to be solved by the device]

 By the way, although such a conventional dental substrate is not harmful to the human body, it does not have the effect of positively preventing tooth decay and gingivitis in the future. In other words, these dental base materials are intended to artificially restore the natural tooth condition, and with regard to the occurrence of tooth decay and the deterioration of gingivitis after the healing, except for the daily careful brushing, it is natural. It is up to the progress.

However, most of the common causes of dental diseases such as tooth decay, gingivitis, and alveolar pyorrhea are due to the properties of saliva, and by solving these problems, the occurrence of dental diseases after dental treatment is improved. Can be suppressed to a minimum.

A brief description of this point is as follows. Ie. Generally speaking, the causes of tooth diseases, such as caries, gingivitis, and alveolar pyorrhea, can be distinguished by firstly blood sugar in the body, secondly poor blood circulation in the gingiva, and thirdly, saliva properties including bacteria. .

The first blood sugar content changes depending on the content of the diet and cannot be solved by tooth brushing or other methods. The second is gingival blood circulation, which can be resolved by careful daily brushing. The third property of saliva, which is the pH of saliva and bacterial activity in saliva, may be exacerbated but not ameliorated if left to natural progress. The pH of saliva becomes acidic due to food, coffee, and alcohol, and along with it, bacterial activities such as Streptococcus mutans and Ginghi Harris are activated, which promotes tooth disease.

Therefore, an object of the present invention is to improve saliva properties after dental treatment and prevent the progress of tooth decay and gingivitis in the future.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object and to achieve the object, the dental base material according to the present invention has an antibacterial ceramic compounded therein.

[0011]

[Action]

 The dental base material according to the present invention contains divalent and trivalent iron salts, zinc oxide, and antibacterial ceramics such as platinum-containing ceramics in its material. These antibacterial ceramics, such as divalent and trivalent iron salts, change saliva pH to weak alkali, suppress the ionic reaction of saliva, and suppress the activity of microorganisms (Japanese Patent Laid-Open No. 61-72627).

When a material containing a divalent and trivalent iron salt is put into water or saliva, the water and saliva are water in which 2 × 10 ⁻¹² mol of the divalent and trivalent iron salt is derived, that is, in the present specification, Change to "active water" used for.

This activated water has a weakly alkaline pH concentration, and therefore can suppress bacterial activity as such, and does not show any ionic reaction. In particular, it is a dental caries such as Streptococcus mutans. It is confirmed that alveolar pyorrhea such as Streptococcus gingii Harris is completely killed.

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of a dental base material according to the present invention, in which a divalent and trivalent iron salt is mixed with a filler 2 for filling a hard tissue defect of a tooth 1.

When there is a defect in hard tissue such as tooth decay, a cavity 3 is formed using a cutting bar, and a filler 2 such as cement, amalgam, or a composite range is filled with the carrier, and a tool such as a burnisher is used. Use to remove the excess part and mold. At this time, the filler 2 is usually used by mixing powder and liquid, but this smelting material (cement, silver-tin alloy, universal, etc.) is kneaded with divalent iron oxide salt or used as the original filling material. A suitable amount of divalent iron oxide salt is mixed with, and this is kneaded with the kneading liquid before use. The amount of the divalent iron oxide salt to be used may be appropriately determined by the doctor according to the size and shape of the sinus 3.

Further, since the treatment of teeth is often performed after a certain number of days, a temporary sealing material such as stoppering or eugenol cement is used for the cavity 3, and this temporary sealing material is divalent iron oxide. By incorporating a salt, it is possible to completely prevent bacteria from entering the cavity 3 before filling.

Further, since the divalent iron oxide salt can be mixed into a resin or ceramic and molded into an arbitrary shape, so-called dentures such as dentures and dentures, denture bases in dentures, or various crowns for restoration of crowns and their There is room for compounding divalent iron oxide salts in all parts of the support, support teeth and adhesive. Since the dental base material present in the oral cavity constantly comes into contact with saliva and exerts an antibacterial action, it is possible to prevent the progress of caries and alveolar pyorrhea after dental treatment to the maximum extent. That is, when a divalent iron oxide salt is mixed with such a dental base material, the property changes of saliva proceed in the following order.

With these base materials, the saliva property changes in pH from acidic to weakly alkaline. This is because saliva water is changed to active water by divalent and trivalent iron salts. As a result, the activity of the pathogenic bacterium is suppressed, and the effect of sucrose on the so-called Kies ring is minimized.

Next, various bacteria of oral and dental diseases existing in saliva water are killed. It takes about 20 hours to kill the purely cultivated bacteria, but when divalent iron oxide salt is added to the dental substrate, the saliva is constantly activated and the bacteria cannot act. Saliva always has an antibacterial effect and completely kills dental germs.

The function of the divalent and trivalent iron salt as described above can be easily confirmed by a simple experiment. For example, it can be confirmed that water is transparent and chlorine reaction does not occur when diluting ferric oxide salt after adding water to a container containing water and turning the water into yellow. It is considered that this is because the water changed to active water in which divalent and trivalent iron salt was induced at 2 × 10 ⁻¹² and did not exhibit ionic reaction. Further, when a weak biomagnetism acts on this active water, as shown in FIG. 2 (a), the electron cloud E of oxygen atoms, hydrogen atoms, etc., which had been randomly aggregated until then, is shown in (b). As described above, nuclear magnetic resonance causes them to split in the direction of the magnetic field, and while they are aligned, they start to rotate around the nucleus all at once, and the water molecules are micronized.

Microorganisms present in the oral cavity are negatively charged, so they cannot survive in micronized and excited saliva. Further, the components of halitosis contained in saliva can also be removed by exciting and miniaturizing saliva.

The action of the divalent and trivalent iron salt according to the present invention becomes more remarkable when the zinc group metal compound is compounded. Further, in order to effectively divide chain-like water molecules and divide water of saliva and oral cells into fine molecules, the dental base material may be made of a resin material containing platinum fibers. This platinum fiber is mainly composed of ceramics that contains about 0.1% to 0.4% of colloidal platinum in about 40% of sintered alumina, about 60% of silica (special characteristics). (Kaisho No. 62-184088), it has an excellent biological action such as in vitro discharge of toxic gas and pollutants contained in saliva and cellular water, and promotion of water molecule permeability to oral cells.

Therefore, for example, when applied to a plate denture, it is effective as a single layer by appropriately combining the denture with a divalent iron oxide salt and the denture base with a platinum resin. It is possible to improve saliva properties. This is because divalent and trivalent iron salts are particularly excellent in antibacterial action, and platinum fiber can be considered to promote the auxiliary function of water molecule decomposition of saliva. The divalent / trivalent iron salt-containing material constituting this dental base material can be manufactured at a cost almost the same as that of the conventional material. This is because the material itself is not particularly expensive. The same applies to zinc oxide.

The base materials used for dental treatment are not limited to those in the above-mentioned embodiment, and there are many kinds, and the present invention does not limit the range of these base materials. For example, glass ionomers in fillers, copper cement used for temporary sealing, sandalac, table coverings and linings for treating pulpitis, inlays in crown restorations, crown bands, jacket crown cores, pinledges, and filling of missing teeth. In the same way, it is possible to add divalent and trivalent iron salts to various instruments used for treatment, such as bridge dummies. For example, various impression materials such as alginate, occlusal sampling materials such as wax, various adhesives such as glues, bone molding fillers, hand instruments such as pincers, expanders, spoons, scalers and stoppers, turbins and handpiece tips. It is a part material. These are used by putting them in the oral cavity, and they can improve saliva properties and completely suppress bacterial activity during and after treatment.

Similarly, a divalent iron oxide salt can be blended and used in a mouthpiece for dentition. This mouthpiece is used, for example, by sandwiching it in your mouth at bedtime. It improves saliva properties during bedtime and suppresses bacterial activity, so it effectively prevents the occurrence of tooth decay and other dental diseases.
