Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an oral health device, and more specifically, it has a shape that covers the tooth surface and the gingival surface, and when used, it is activated by the occlusion of the teeth to form a rubber elastic body. The present invention relates to an oral health tool that provides a tooth brushing effect and a gingival pine surge effect.

[Conventional technology] Conventional tooth brushing methods, such as toothbrushes and toothpastes, target a range of 2 to 3 teeth in one motion, and are unable to uniformly and cleanly brush the entire surface of the tooth. It has the disadvantage that it cannot reliably clean the teeth and oral tissues all at once. Therefore, instructions on brushing given by professionals such as dentists and dental hygienists have not become fully established among the general public due to the difficulty of the method.

In addition, although gingival masturbation is said to be effective in preventing interdental disease along with tooth brushing, there is no appropriate gingival masturbation equipment.
It is thought that this is rarely implemented on a daily basis.

On the other hand, experts point out that with the development of food processing technology, all kinds of food are being softened, and there is a proliferation of foods that require less chewing, resulting in a lack of chewing.
It is said to be a cause of frequent interdental disease and hinder intellectual development in young people.

As mentioned above, inadequacies in tooth brushing tools, difficulty in tooth brushing and gingival surgery, eating and drinking habits, etc. are serious problems in oral health, and there is a demand for excellent oral health tools that address these problems. was.

[Structure of the invention]

The present invention relates to an oral health device that meets this need, and has a shape that covers the tooth surface of the upper or lower jaw and the gingival surface adjacent to the tooth, and that has multiple parts on the occlusal surface of the tooth and the portion that contacts the tooth neck. A structure consisting of two layers: a rubber elastic body provided with small protrusions and a reinforcing material covering the outside of this rubber elastic body, and further provided with a plurality of penetrating small holes in the part that contacts the side surface of the tooth. Or a rubber elastic body having a shape that covers the tooth surface and the gingival surface adjacent to the tooth and having a plurality of small protrusions on the part that contacts the occlusal surface and tooth neck of the tooth, and this rubber elastic body. The upper and lower jaw structures are made of two layers: a reinforcing material that covers the outside of the teeth, and a plurality of small holes that pass through the parts that contact the side surfaces of the teeth. This relates to an oral health device that is integrated with the occlusal surfaces of the teeth.

That is, the present inventor conducted various studies in order to meet the above-mentioned needs, and developed a rubber elastic body having a shape that covers the tooth surface and the gingival surface adjacent to the tooth, by repeatedly pressing and separating the tooth surface and the gingival surface. They discovered that if they were moved in a continuous manner, a friction effect would be produced, which would not only provide a cleaning effect but also a pine surge effect on the gums, and after further study on the shape and structure, they completed the invention.

When the oral health tool of the present invention (hereinafter abbreviated as one tool) covers the entire row of teeth, its overall appearance is approximately U-shaped. The cross section for the upper or lower jaw is generally concave and covers the tooth surface and the gingival surface adjacent to the tooth. However, it is also possible for one tool to cover part of the tooth row instead of the entire tooth row.

The rubber elastic layer of this tool needs to have multiple small protrusions on the part that contacts the occlusal surface of the teeth and the part that contacts the tooth neck. It has the function of separating the tool from the tooth surface or gingival surface by the repulsive force. Furthermore, when the teeth are engaged, the rubber elastic body is crushed by the pressing force and comes into close contact with the tooth surface or the gingival surface. By repeating this relative movement, the rubber elastic body repeatedly presses and rubs the tooth surface or gingival surface, resulting in a cleaning effect and a pine surge effect. Silicone rubber is suitable as the material for the rubber from the viewpoints of processability, non-toxicity, elasticity, etc.

The reinforcing material layer that covers the outside of the rubber elastic layer protects and reinforces the rubber elastic layer, and evenly transmits the pressing force when the teeth are brought into close contact. Note 1: Uniform positioning and pressure force transmission can be achieved. The material is preferably acrylic, and by combining the structures for the upper and lower jaws at the occlusal surfaces of their reinforcing materials and integrating them, the upper and lower tooth surfaces and gingival surfaces can be cleaned and treated at the same time. You can get the tools for this.

The small holes provided in the part of this tool that are in contact with the side surfaces of the teeth are passages for air to enter and exit during the above-mentioned relative movement, and these small holes are necessary for smoothing the relative movement and for cleaning and achieving the pine surge effect. It is something.

Next, the present invention will be explained based on one embodiment.

An example of this tool is shown in Fig. 1, and is composed of a rubber elastic layer 1 and a reinforcing material layer 2, and has small protrusions 3 and small holes 46, and its cross section is shown in Fig. 2. This is shown below. When this is attached to the tooth, it will be separated from the tooth surface or gingival surface when no pressure is applied, as shown in Figure 3, and when pressed, it will be in close contact as shown in Figure 4.

An example of the manufacturing process for one tool is shown in (a) to (f) below.
It consists of

(B) Preparation of tooth mold A plaster model (convex type) is made from the impression tooth mold (concave type), and the marginal line of the product is set at a position of 81 mm from the tooth cervical line to the gingival side of this model, and the rubber Convex portions are provided on the buccal and lingual bulges of the teeth to provide small through holes in the elastic body. Next, a small hole with a depth of about 1 m and a diameter of 1 mm was made in the cusp of the back teeth and in the center of the incisal edge of the front teeth of the model, and wedge-shaped grooves were carved into all teeth on the cervical line on the buccal and lingual sides. , and further scrape off the surface of the tooth row recess by about 0.3+am.

(b) Space setting for rubber elastic body Paraffin wax with a thickness of about 1.8 mm is heated and softened, and pressed onto the model made in step (a). After hardening, the excess area outside the edge line and small holes are Remove the paraffin wax from the setting area.

(c) Setting space for reinforcing material An overall impression is made on top of the paraffin wax mold after the above step (b), and a plaster replica model (convex mold) is further made.

A space is set for this duplicate model in the same manner as in step (b). At that time, the edge of the food material should be approximately 2 mm closer to the tooth neck than the edge of the rubber elastic body.

(d) Preparation of reinforcing material The composite model obtained in steps (a) to (c) above is filled with gypsum in the lower frame of a flask for denture base polymerization, and a gypsum separating agent is applied.
Once it dries, the top frame is placed on top and plaster mud is poured and allowed to harden. The paraffin wax is then removed by heating and melting to obtain a plaster mold. A mold release agent is applied to this, a prepolymerized mixture of an acrylic polymer and an acrylic monomer is charged, and the material is heated and polymerized to obtain a reinforcing material.

(e) Preparation of rubber elastic body Fit the model covered with paraffin wax made in step (b) above and the reinforcing material made in step (d) above,
A plaster mold is prepared in the same manner as in step (d), and the silicone rubber raw material is filled and heat vulcanized. A small hole is also made in the reinforcing material at a position that corresponds to the small through hole in the rubber elastic body.

(f) Marking of the occlusal position of the opposing teeth (e) After the process is completed, the rubber elastic body and reinforcing material molded body are returned to the tooth model used in the (e) process, transferred to the articulator, and polymerized at room temperature. Place acrylic resin on the occlusal surface of the reinforcing material and mark the occlusal position of the gold tooth.

When finishing the upper and lower parts as one piece, the upper and lower molded parts are interlocked in the same way, and instead of marking the teeth, the two are joined with acrylic resin.

This tool produced in this way can be smoothly moved up and down by 1 mm or more during use, and can normally perform sufficient cleaning with about 50 up and down movements, and has a remarkable pine surge effect on the gums.
