Description

  The present invention relates to a denture stabilizer capable of fixing a denture on a jaw softly and firmly for a long time by utilizing the adhesiveness of an oblate and a gel.

  What is important for making dentures, especially complete dentures, is the impression of using a personal tray. A base plate is made from this impression, and an occlusal floor is made by placing wax on the base plate. An artificial tooth arrangement is formed in the wax portion of the occlusal floor using an articulator to obtain a denture. Thereafter, the wax is re-applied to the base plate, and when the denture arrangement and the meat formation are completed, the denture is embedded in gypsum in the flask, and the wax is melted by heating and the base plate is removed to prepare a mold. Subsequently, the wax and base plate are taken out, a gingival pink resin is injected into the space formed and pressed, and the flask is heated to solidify the resin. When the polymerization is over, remove from the flask, break the plaster and dig out the denture. The denture thus obtained is set in an articulator, the adjustment of the meshing is repeated, and deburring and polishing are performed to complete the complete denture. The above is an example of a dental technician who makes a complete denture.

  All dentures mentioned above fit well when you have just made a new denture, but they do not fit while you are using them. This is because, when a thing is bitten, the raw gums and sometimes even the jaw bone are deformed by the applied force. As a result, the trouble that dentures do not fit directly arises. It is not easy to solve this problem, but it is certain that there are many patients who are suffering, so it needs to be solved somehow.

  For this reason, powdered or creamy denture stabilizers are commercially available. To use a powdered denture stabilizer, wash the denture, especially the surface that touches the gums and jaws, make it slightly moistened, sprinkle the powder evenly, fit the denture, and hold it firmly with your fingers. Wait until it is stable. In the case of a cream-like denture stabilizer, it is squeezed to several places on the surface of the denture that touches the gums and jaws, and the denture is fitted and pressed with a finger for a while. The cream contains saliva and exhibits stickiness to stabilize dentures. These denture stabilizers are gradually dissolved, but they are made so that there is no problem even if they are swallowed.

  Utility model registration No. 3093209 is a total denture-stable gum-relief sheet, which is made of absorbent cotton and made into a semi-circular upper denture sheet and a belt-like lower denture sheet. Pressed, shaped and dried. According to this denture sheet, scissors can be used to shape each different denture depending on the person, and when water is applied, the starch instantly dissolves and can be easily applied to the denture. There is an advantage that it can be changed.

  Powdered and creamed denture stabilizers gradually dissolve during use, but there is a problem that the effect does not last so long because this time is short. The denture sheet of Utility Model Registration No. 3093209 certainly has a certain effect, but as the glue solution becomes thinner, the absorbent cotton becomes harder and feels uncomfortable. As above, there is a problem that the effect does not last long.

Utility model registration No. 3093209

  As mentioned above, since it was a denture made with great care, I thought it would be possible to continue to provide patients with a comfortable feeling for a long time. This invention makes it a subject to solve such a problem.

  Prior to solving the above-mentioned problems, the present inventor obtained knowledge that it should be applied to dentures and have good cushioning properties and durability.

  That is, the above-mentioned problem is a denture stabilizer for adhering to a denture, having an adhesive layer in which starch or agar is gelatinized, and a surface in contact with the upper jaw of the upper denture or in contact with the lower gum of the lower denture This is achieved by providing a denture stabilizer formed by molding into the shape of Since starch and agar are gelatinized and formed into a surface that contacts the jaw, it adheres directly to the surface that contacts the denture's jaw and can also be firmly fixed to the denture. Moreover, by taking a large thickness, the cushioning property is improved and it can withstand long-time use. In addition, since starch and agar are gradually dissolved in saliva, the thickness may be determined in consideration of the use time.

  Further, the above-mentioned problem is a denture stabilizer for adhering to a denture, which has an adhesive layer of an oblate having a thickness of 1 mm or more and 3 mm or less, and on the surface contacting the upper jaw of the upper denture or under the lower denture This is achieved by providing a denture stabilizer formed into the shape of the surface in contact with the gums. Oblate is produced by gelatinizing the starch and then drying it, and at this time, the thickness is within the above range. Since this is in the shape of a surface in contact with the jaw, the denture can be firmly fixed to the jaw by adhering it to the surface in contact with the jaw of the denture. In addition, when the thickness is in the above range, the cushioning property is good and gradually dissolves in saliva, but can withstand long-term use.

  Oblates are easily soluble or hardly soluble, and those having the same thickness and area can be provided with different dissolution times. Alternatively, it is possible to provide a plurality of types of products so that the patient can freely select, for example, those having a dissolution time of 3 hours or those having a dissolution time of 6 hours. Also, for example, it is possible to provide a plurality of types of products that are different in terms of touch to the jaw, such as softness, softness, regularity, and hardness.

  Another object of the present invention is to provide a denture stabilizer characterized in that it is a denture stabilizer that adheres to a denture, and a gel layer is formed on an oblate sheet-like base material as an adhesive layer. Is achieved. This denture stabilizer is composed of at least two layers, and since there is a base material, for example, when the shape of the surface in contact with the jaw is maintained, the shape is maintained, and the gel layer is stable even if it is thick. Can be held. The gel layer has good adhesion and cushioning to dentures and jaws. Both the denture stabilizer gel layer and the substrate made of oblate gradually dissolve in saliva. The easy solubility and poor solubility of the substrate made of wafer are as described above.

  The gel layer may be formed on one side of the substrate. In this case, the denture should be adhered from the side of the substrate made of oblate. Then it is the gel layer that adheres to the jaw. In addition, it is related to the above-mentioned easily soluble or hardly soluble, but by designing the substrate made of oblate to be less soluble than the gel layer, the base layer side is made to adhere to the denture, so that the gel layer Since the base material side is left even though it is being lost by saliva, the denture can be held on the jaw by the adhesive force of the base material. In this case, the base material corresponds to an adhesive portion described later.

  The gel layer may be formed on both side surfaces of the substrate. The substrate is sandwiched between two gel layers. Therefore, the gel layer on one side adheres to the denture and the gel layer on the other side adheres to the jaw, and the cushioning property is improved. Between these, the substrate made of oblate becomes the core of the two gel layers.

  On the contrary, the gel layer may be formed between the two base materials. The gel layer has an substrate made of wafer on both sides, and one side of the substrate made of wafer adheres to the denture and the other to the jaw. In the meantime, the gel layer exhibits good cushioning properties, but gradually dissolves in saliva.

  The gel layer may be attached to the both sides of the base material, and the base material may be embedded in the gel layer. Then, although the edge part of the substrate made of wafer is covered with the gel layer, it plays a role as a core. The thing of such a structure can also be provided.

  In addition, regarding the denture stabilizer of Claims 3-5, it is good also considering that the said gel uses sodium alginate as a main raw material. Polysaccharide sodium alginate (Sodium alginate (NaC6H7O6) n) is mainly contained in natural seaweed and the like, and gels when magnesium ions or calcium ions are added. This is one of the effective materials for the coating of the substrate made of oblate of the present invention and the production of the gel layer. For the formation of the gel layer, a gelling agent such as starch, agar, or pectin may be arbitrarily used.

  Moreover, it is good also as what has the adhesion part which is hard to melt | dissolve with the said adhesion layer regarding the denture stabilizer of Claims 1-6. This point was also explained in paragraph 0014, but even if the side that is more soluble in saliva etc. is lost, the adhesive force of the adhesive part that is less soluble can act and the denture can be held on the jaw. It is. In addition, what was described in paragraph 0014 was an adhesive layer composed of an oblate base material and a gel layer. For example, as described in paragraph 0010, an adhesive layer in which starch or agar was gelatinized was used. Separately, a configuration in which an adhesive part that is more difficult to dissolve, such as by dispersing a granular adhesive that is more difficult to dissolve than the adhesive layer, is possible. In addition to interspersed granular adhesive portions, a band-like or net-like adhesive portion can be arbitrarily designed.

  According to the present invention, starch or agar gelatinized, an oblate having a thickness of 2 mm or more, or an oblate sheet-like base material on which a gel layer is formed is brought into contact with the upper jaw of the upper denture. Providing a denture stabilizer that has good cushioning properties and can withstand long-term use, in which the surface or the shape of the surface that contacts the lower gums of the lower denture is attached to the denture and adhered to the jaw done. This has the effect that important dentures can continue to be used for a long time with a comfortable feel.

  It is explanatory drawing of the use condition of the denture stabilizer 1 for the upper jaw of Example 1, and the complete dentures 2.

  The denture stabilizer 1 for adhering to the upper complete denture 2 will be described with reference to FIG. In the complete denture 2, the contact surface 22 of the denture base 20 on which the artificial tooth arrangement 21 is formed, which is the side that comes into contact with the raw upper jaw, is formed into a smooth surface.

  The denture stabilizer 1 of Example 1 is used by adhering to the maxillary full denture 2 as described above. The denture stabilizer 1 is an agar jelly 10 formed by gelatinizing agar, and the contact surface 22 of the complete denture 2. It is formed into a shape. Although not shown, a thin cover is provided on both sides of the agar jelly 10, the denture side surface 11 and the jaw side surface 12 to prevent unintentional adhesion and contamination before use. The cover is removed.

  Therefore, after denture stabilizer 1 is adhered to the contact surface 22 of the complete denture 2 from the denture side surface 11, and the complete denture 2 is mounted in the mouth, the denture is adhered to the contact surface 22 that touches the upper jaw of the complete denture 2. Via the stabilizer 1, the jaw side surface 12 adheres to the upper jaw and is fixed to the upper jaw. The denture stabilizer 1 has good cushioning properties. The denture stabilizer 1 is gradually dissolved by saliva, but can be used for a long time with a comfortable feeling.

  The denture stabilizer 3 for adhering to the complete denture 4 for the lower jaw will be described with reference to FIG. In the complete denture 4, the contact surface 42 on the side of the denture base 40, on which the artificial tooth arrangement 41 is formed, on the side touching the lower jaw, is formed into a smooth surface.

  The denture stabilizer 3 of Example 2 is used by adhering to such a complete denture 4 for the lower jaw, and is composed of an oblate 30 having a thickness of 3 mm and is also a contact surface 42 of the complete denture 4. It is formed by forming a substantially U-shaped portion. The side of the oblate 30 that adheres to the contact surface 42 is the denture side surface 31, and the side that adheres to the lower jaw is the jaw side surface 32. The inside of the denture stabilizer 3 is softer than the outer surface.

  After this denture stabilizer 3 is adhered to the contact surface 42 of the complete denture 4, the complete denture 4 is mounted in the mouth. In this case, all adheres to the lower jaw via the denture stabilizer 3 which adheres to the contact surface 42 that touches the lower jaw of the denture 4. Oblate 30 exhibits adhesiveness with saliva, and denture side 31 is strongly adhered to contact surface 42 and jaw side 32 is firmly adhered to the lower jaw. At this time, the denture stabilizer 3 has cushioning properties. Further, although the wafer 30 of the denture stabilizer 3 is gradually dissolved by saliva, it can be used for a long time with a comfortable feeling.

  The 3 mm thick wafer can also be obtained, for example, by polymerizing 15 sheets of medicated sheet-shaped wafer having a thickness of 20 μm.

  FIG. 3 is a schematic view showing this embodiment in cross-section. The denture stabilizer 5 is formed by providing a sheet-like wafer 51 layer as the base material on one side of a gel layer 52 made of a gel-like substance containing sodium alginate as a main raw material. It should be noted that the shape differs depending on whether it is to adhere to the upper jaw or to the lower jaw.

  Whether the denture stabilizer 5 is adhered to the chin on the surface of the gel layer 52 or whether it is adhered to the chin on the surface of the oblate 51 is left to the patient's preference. The oblate 51 and the gel layer 52 may be arbitrarily designed to have the same or different melting conditions.

  FIG. 4 is a schematic view showing this embodiment in cross-section. The denture stabilizer 6 is formed by providing sheet-like oblates 61 and 61 as the base material on both sides of a gel layer 62 made of a gel-like material containing sodium alginate as a main raw material. The overall planar shape of the denture stabilizer 6 differs depending on whether it is adhered to the upper jaw or the lower jaw.

  By forming the layers of oblates 61 and 61 as the base material on both sides of the gel layer 62, the gel layer 62 can be stably held from both sides.

  FIG. 5 is a schematic view showing this embodiment in cross-section. The denture stabilizer 6 is formed by embedding a sheet-like wafer 71 layer in a gel layer 72 made of a gel-like material containing sodium alginate as a main raw material. Although the oblate 71 layer is covered with the gel layer 72, it can serve as a core. The gel layer 72 acts as a good quality cushion for both the denture and the jaw.

  In addition, it is also possible to use a design that uses an oblate 73 that is attached to the left and right sides of the gel layer 72 in FIG. That is, the wafer 73 is sandwiched between the two gel layers 72 and 72 from both sides like a sandwich. In this case, the gel layer 72 on one side adheres to the denture, and the gel layer 72 on the other side adheres to the jaw, so that a good cushioning property is exhibited for all.

  The denture stabilizer 8 for adhering to the maxillary full denture will be described with reference to FIG. All dentures are formed with a smooth contact surface on the side that touches the upper jaw of the living body.
