Description

  The present invention relates to a denture stabilization grip for a partial denture that is interposed between a denture and a gingiva to stabilize the partial denture.

  Dentures substitute for lost teeth, and there are complete dentures for those who have no teeth and partial dentures for those who have no teeth. Both have a structure that supports the force of biting by the mucous membrane of the gums where the teeth are removed. Dentures are composed of artificial gums and artificial teeth, and are made to chew food with artificial teeth by fixing the artificial gums in close contact with the wearer's original gums. However, a major problem with such dentures is that a slight gap remains between the artificial gum and the original gum, so if foreign objects get mixed in this gap, pain will occur when you bite something. become. In addition, the occurrence of a gap means that the denture is not stably fixed, and it may come off as it is or an abnormal meshing may occur.

  In order to eliminate such problems, a gel-like material called “denture stabilizing material” or the like that has been popular in recent years is commercially available in a form enclosed in a tube or the like. The denture user uses the gel-like stabilizing material in a necessary amount on the artificial gum and presses it against the gum so as to extend and spread uniformly between the artificial gum. However, if such a gel-like stabilizer is used in a slight amount or if it is engaged with a large pressure, it will protrude outside the artificial gums due to the pressure of the engagement, and it will feel uncomfortable. Become. Furthermore, there is a risk that a part of the protrusion will be torn off and taken into the body as it is. On the other hand, when the usage amount is too small, the gap between the artificial gum and the gum is not sufficiently filled, and thus the above-mentioned troubles due to foreign matter mixing may occur. However, this “denture stabilizing material” can be used for total dentures, but in the case of partial dentures, it cannot be used because the joint area with the gums is small and the strength is insufficient.

  In order to solve the problem of the gel-like stabilizer, a denture stabilizer that is interposed between the denture and the gum and stabilizes the denture has been proposed. For example, in Japanese Patent Laid-Open No. 2000-316883 (Patent Document 1), a denture stabilizer in which a nonwoven fabric having elasticity in the thickness direction is formed in a sheet shape between an artificial gum and a palate of a denture, It is disclosed that the denture is stabilized by bringing the denture into close contact with the palate. Japanese Patent Laid-Open No. 2002-186633 (Patent Document 2) provides a large number of dimples on one side of a flexible sheet that is interposed between the gum mucosa surface and the denture base 7 in contact with the gum mucosa surface of the sheet. It is disclosed that when occlusal pressure is applied to the teeth, the sheet dimples are strongly pressed against the gum mucosa surface, and the air in the dimples is pushed out to a negative pressure to be adsorbed on the gum mucosa surface.

JP 2000-316883 A JP 2002-186633 A

  The denture stabilizing material shown in Patent Document 1 is formed of a non-woven fabric formed in substantially the same shape as the adhesion surface of the artificial gum of the upper denture, and wets the adhesion surface with water to adhere the denture stabilizing material. Therefore, it is attached to the palate of the human body. However, since the denture stabilizer is formed of a non-woven fabric, food or the like soaks into the non-woven fabric and cannot be left unattended. Therefore, there is a problem that the denture stabilizer used after a meal must be discarded. In addition, the stable and painless adsorption sheet for dentures described in Patent Document 2 is provided with a large number of shallow small dimples on one side 3 of the sheet, and the dimple is adsorbed with a negative pressure. In order to form the dimples, the sheet must be formed thick, which increases the rigidity, so that there is a problem that the adsorbing portion with the gum mucosa surface is reduced and a predetermined adsorbing effect cannot be obtained. . In addition, since it is formed on an uneven surface by dimples, it may feel uncomfortable when worn on the palate of a human body. Such denture stabilizing materials and adsorbing sheets described in Patent Document 1 and Patent Document 2 are also used for total dentures, and even if used for partial dentures, the bonding area with the gums is small, so the bonding strength is low. Cannot be used due to lack.

  In view of the above problems, the problem of the present invention is that the partial denture denture can be flexibly brought into close contact with the gingiva, and the remaining teeth between the partial denture dentures are exposed to be beautiful. It is to provide an excellent stable grip for a partial denture.

  In order to solve the above problems, a partial denture stability grip according to the present invention includes a partial denture composed of a denture base and artificial teeth mounted on both sides of a remaining tooth, and is interposed between the partial denture and a gingiva. A stable grip for stabilizing the partial denture, wherein the stable grip is made to correspond to the cylindrical portion having a smooth deformable surface having a thickness of 0.1 mm to 0.4 mm and the remaining tooth. When the partial denture is formed, the tube portion is covered with the partial denture, the bridge portion is made to correspond to the residual tooth, and the partial denture is mounted, the bridge portion is attached to the back surface of the residual tooth. The gist is that the stable grip interposed between the gingiva and the denture base is adsorbed by moisture.

  The stable grip is preferably formed of a synthetic resin made of polyvinyl acetate, polyethylene, nitrile, vinyl chloride or the like, or latex.

  According to the stable grip for partial dentures of the present invention, the stable grip is formed of a plate material having a smooth, deformable surface having a thickness of 0.1 mm to 0.4 mm. Therefore, the denture can be brought into close contact with the shape of the gingiva covering the jawbone and the denture base, and the stability of the denture can be ensured. In addition, since the stable grip is formed to be extremely thin, even if a crease occurs in the stable grip, it is possible to maintain a good wearing feeling without causing pain or discomfort to the user. In addition, since the stable grip is extremely thin, the possibility of foreign matter being mixed between the gingiva and the denture base is eliminated. Furthermore, since the stable grip is adsorbed by moisture such as non-toxic water or saliva, safety for the user can be obtained. In addition, when this partial denture stability grip is mounted on both sides so that the remaining teeth are sandwiched, the bridge portion can be disposed on the back surface of the remaining teeth, so that the remaining teeth are exposed, which may impair the appearance. There is no. Furthermore, since almost all of the partial denture is formed in a cylindrical shape, it can be mounted by inserting it into the denture in advance, making it unnecessary to position the denture and the stable grip, making it easy even for elderly people Can be attached to.

  If synthetic resin or latex made of polyvinyl acetate, polyethylene, nitrile, vinyl chloride or the like is used as the material for the stable grip, these materials will break even if they are 0.1 mm to 0.4 mm thick. It can be deformed flexibly and adsorbed closely to the gingiva and denture base. In particular, polyvinyl acetate is a colorless and transparent resin that does not dissolve in water and is tasteless and odorless. It is a harmless material that meets the strict standards of the Food Sanitation Act, and maintains safety even when dentures are used for a long time. can do.

  The partial denture stability grip according to the present invention comprises a partial denture composed of a denture base and artificial teeth mounted on both sides of the remaining tooth, and the partial denture interposed between the partial denture and the gingiva. A stable grip for stabilizing, wherein the stable grip is formed with a cylindrical portion having a smooth deformable surface having a thickness of 0.1 mm to 0.4 mm, and a bridge portion corresponding to the remaining teeth, The partial denture is covered with the tube portion, the bridge portion is made to correspond to the remaining tooth, and when the partial denture is attached, the bridge portion is arranged on the back surface of the remaining tooth, and the gingiva and the The stable grip interposed between the denture bases is adsorbed by moisture.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a state in which a partial denture stability grip according to the present invention is mounted. As shown in FIG. 2, the partial denture 1 has two artificial teeth 1b spaced apart from the denture base 1a. The interval between the artificial teeth 1b is set to a width in which the remaining teeth 10 are arranged. The denture base 1a has a substantially U-shaped cross section so that the inner surface is joined to the gingiva 11 on both sides of the remaining tooth 10, and the remaining tooth 10 is inserted between the two artificial teeth 1b. A through hole 1c is formed. In addition, although said residual tooth 10 is demonstrated as a tooth | gear shown between the two artificial teeth 1b, it exists also in the side of the partial denture 1 as shown in FIG. 1, FIG. Of course.

  The partial denture 1 is covered with a denture base 1a and two artificial teeth 1b by a partial base denture stability grip 2 (hereinafter abbreviated as a stable grip). As shown in FIG. 2, the stable grip 2 can be mounted by being inserted from one end of the partial denture 1.

  The stable grip 2 is formed of a plate material having a smooth deformable surface and a thickness of 0.1 mm to 0.4 mm. As the stable grip 2, polyvinyl acetate is suitable. Polyvinyl acetate is a colorless, transparent, water-insoluble, tasteless and odorless resin, and is a harmless material that meets the stringent standards of the Food Sanitation Law, as used in chewing gum base materials. As shown in FIG. 2, this polyvinyl acetate is formed with a cylindrical portion 2a on both ends and a bridge portion 2b so as to connect the cylindrical portion 2a as shown in FIG. As illustrated, the bridge portion 2b is formed by a remaining portion in which a through hole is formed between the cylindrical portions 2a. The length of the bridge portion 2 b is the same as or smaller than the width of the remaining tooth 10. In addition, the inner diameter of the cylindrical portion 2 a is set to a dimension that is slightly larger than the outer dimension of the partial denture 1, and the lateral width is the same as or slightly larger than the width of the partial denture 1.

  Next, the procedure for mounting the partial denture 1 on the gingiva will be described. As shown in FIG. 2, the stability grip 2 is inserted into the partial denture 1, and the cylindrical portion 2a is made to correspond to the artificial teeth 1b on both sides as shown in FIG. Thereby, the bridge | bridging part 2b respond | corresponds to the through-hole 1c.

  Thus, as shown in FIG. 2, the partial denture 1 in which the stable grip 2 is inserted is inserted from above and is inserted until the upper surface of the gum 11 is reached while the remaining teeth 10 are inserted through the through holes 1c. At this time, the bridge portion 2b is arranged so as to be the back surface of the remaining tooth 10 as shown in FIG. As a result, the surface of the remaining tooth 10 is exposed.

  And if water is made to adhere a little to the inner surface of the stable grip 2, when it presses against the gingiva 11, the stable grip 2 and the denture base 1a will be in a vacuum state by a water film, and both will closely adsorb | suck firmly. . On the other hand, since moisture such as saliva is interposed between the stable grip 2 and the gingiva 4, the stable grip 2 and the gingival 4 are in a vacuum state, and both are in an adsorbed state, and this state is maintained. In this way, by attaching the denture 1 fitted with the cylindrical stable grip 2 to the gingiva 11, the artificial tooth 1 b of the partial denture 1 is covered with the stable grip 2. When food is chewed in this state, the stable grip 2 is pressed. However, since the partial denture 1 is formed so as to have good meshing, the upper and lower teeth chew food on the surface, so that the stable grip 2 is hardly broken. Moreover, since the upper surfaces of the remaining teeth 10 between the artificial teeth 1b are exposed like other remaining teeth, food can be chewed in the same way as normal teeth.

  The above-described stable grip 2 has a thickness of 0.1 mm to 0.4 mm. This is the thickness obtained by various experiments. When the stable grip 2 having a thickness of 0.1 mm or less is used, it becomes relatively easy to break, and when the food is chewed, it becomes relatively easy to break, and the life is shortened and it is not practical. On the other hand, when it is thicker than 0.4 mm, it is difficult to break, but it is difficult to deform in accordance with the shapes of the denture 1 and the gingiva 4 due to less flexibility. May leave. The thickness of the stable grip 2 that can maintain safety even when the denture 1 is used for a long time is preferably 0.1 mm to 0.4 mm.

  The stable grip 2 shown in the above-described embodiment is formed so as to be adapted to the partial denture 1 used when both sides of the remaining tooth 10 are lost. However, the number of remaining teeth or the missing part may be different. The stable grip shown in FIG. 5 is formed so as to be adapted to various partial dentures 1. In the stable grip 20 shown in FIG. 5A, the through holes forming the bridge portion 20b are formed in a substantially square shape. The cylindrical portions 20a on both sides are the same as in the above-described embodiment. The stable grip 21 shown in FIG. 5 (B) has two through holes for separating the bridge portion 21b and forming it at two locations. The cylindrical portions 21a on both sides are the same as in the above-described embodiment. Furthermore, the stable grip 22 shown in FIG. 5 (C) is used when there are a plurality of remaining teeth, and the width of the through-hole is formed large in order to lengthen the bridge portion 22b. The cylindrical portions 22a on both sides are the same as in the above-described embodiment. Thus, the stable grip is formed in an appropriate shape according to the form of the partial denture 1.

  Although the present invention has been specifically described above based on the embodiments, it is needless to say that the present invention is not limited to the above embodiments and can be variously modified without departing from the gist thereof. The shape of the stable grip is a flexible resin and may not necessarily be held in a cylindrical shape as shown in the figure, but may be a polygon such as a square as an original shape.
