Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet denture stabilizer for a lower jaw, and more particularly to a sheet denture stabilizer formed so as to correspond to the three-dimensional shape of the denture attachment surface of the lower denture.

[0002]

2. Description of the Related Art Conventionally, a powder-type denture stabilizer made of a water-soluble polymer or the like has been used as a means for stably mounting a denture on a mandibular ridge (contact surface with a denture such as a gum or a palate). Also, cream-type denture stabilizers in which this is mixed with an oil component such as petrolatum are known. However, for these types of denture stabilizers, an appropriate amount of the denture is taken out of the container and the denture is attached to the denture-adhering surface (in the present specification, the denture-adhering surface means the surface of the denture that adheres to the gums, palate, etc. ), It is necessary to apply it with an appropriate thickness, and it is sometimes difficult and troublesome to use. Furthermore, since the denture stabilizer of the cream type is strongly sticky and contains an oil component, cleaning of the denture tends to be troublesome.

[0003] As another type of denture stabilizer, a gum-based cushion-type denture stabilizer having no water solubility is also known. However, the denture stabilizer of the cushion type is very hard, and it is difficult to remove the denture from the tube and apply it to an appropriate thickness on the surface where the denture is adhered, and cleaning of the denture is troublesome.

As a denture stabilizing means for solving the above-mentioned problems, there is known a sheet type denture stabilizer formed by solidifying a denture stabilizer in a sheet shape according to the shape of a denture attachment surface. ing. Unlike a cream-type stabilizer, the sheet-type denture stabilizer does not need to be applied on the denture-adhering surface and is relatively simple to use, so that the denture can be worn in a short time.

A denture stabilizing sheet having a structure in which a denture stabilizer is interposed between two upper and lower sheets is disclosed in US Pat. No. 4,503,116. The denture stabilizing sheet described in U.S. Pat. No. 4,503,116 is composed of cellulose paper provided as a support and holding fibers such as cellulose acetate.
It has a three-layer structure in which a denture stabilizer is interposed between the webs. As a drug, an ethylene oxide polymer is used as a denture stabilizer, and sodium alginate is used as a rewet adhesive. In this three-layer structure, an integral structure is formed by entanglement of the entangled fibers of a pair of webs with a needle punch or heat welding of a part of a powdery ethylene oxide polymer used as a denture stabilizer. Is done. Thereby, delamination of the denture stabilizing sheet is prevented. When using the denture stabilizing sheet, an extra portion of the sheet is cut off with scissors or the like so as to match the shape of the denture attachment surface as necessary.

[0006]

However, conventional sheet-type denture stabilizers (hereinafter simply referred to as sheets) such as the above-mentioned sheet-type denture stabilizers and denture stabilizing sheets.
Many of them have a flat shape adapted to the planar shape of the artificial tooth attachment surface, and when actually affixed, they did not conform to the shape of the artificial tooth attachment surface three-dimensionally, and easily wrinkled in the sheet.

[0007] That is, although the lower jaw sheet type denture stabilizer (lower jaw sheet) is formed substantially U-shaped according to the planar shape of the denture attachment surface, it is three-dimensionally formed of the lower denture denture. When this is attached on the artificial tooth attachment surface, the curve (flexion rate) is the strongest, particularly on the inner circumferential side of the central part in the left-right width direction of the U-shaped artificial tooth attachment surface (that is, the tip of the U-shape). However, the sheet did not properly conform to the three-dimensional shape of the denture attachment surface. Furthermore, since the dentures produced at the order of the individual have different bending rates at the U-shaped tip, the sheet may not be suitable for some dentures. As described above, the conventional lower jaw sheet is not good in wearing feeling, such as wrinkles and the like, which tend to be generated particularly at the U-shaped tip portion when attached, giving an uncomfortable feeling and pain when wearing the denture.

The present invention has been made to solve the above problem, and provides a sheet-type denture stabilizer for a lower denture, which enables a denture to be stably mounted with a good wearing feeling. That is its purpose.

[0009]

SUMMARY OF THE INVENTION A sheet-type denture stabilizer for a lower jaw according to the present invention comprises a fabric having a U-shape corresponding to a denture attachment surface of a lower denture and a denture stabilizer held on the cloth. The U-shaped inner peripheral side is provided with a cut portion at a central portion in the width direction of the fabric on the inner peripheral side to facilitate bending around the central portion. Achieve the goal.

[0010] The cloth may be made of a cotton nonwoven fabric.

Alternatively, the sheet-type denture stabilizer for lower jaw of the present invention comprises a denture stabilizer formed in a sheet shape having a U-shape corresponding to the denture-adhering surface of the lower-layer denture. A notch for facilitating bending around the central portion is provided at a central portion in the width direction of the sheet-shaped denture stabilizer on the peripheral side, thereby achieving the above object.

The operation of the present invention will be described below.

[0013] The sheet-shaped denture stabilizer for lower jaw of the present invention is U-shaped.
Since the cut portion is provided at the center in the width direction of the fabric on the inner peripheral side of the character shape, bending of the stabilizer is facilitated,
Thereby, it easily matches with the three-dimensional shape of the denture attachment surface of the lower denture. Therefore, the sheet-shaped denture stabilizer for lower jaw of the present invention does not form wrinkles or the like, and is adhered on the denture attachment surface of the lower denture with a substantially uniform thickness.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a seat-type denture stabilizer for a lower jaw according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a lower jaw sheet type denture stabilizer (lower jaw sheet) 10 of the present embodiment. Lower jaw sheet 10
Is generally U-shaped or substantially V-shaped as shown in FIG. 1, and the overall shape is the attachment surface of the mandibular denture (the attachment surface with the gum, palate, etc. in the denture base). It almost corresponds to the planar shape of.

Further, the lower jaw sheet 10 has a shape having a cutout 12 toward the outer peripheral side of the sheet at the center (front end) 10c in the width direction on the inner peripheral side of the U-shape.

In one embodiment, the dimensions shown in FIG. 1 are, for example, as follows.

Left and right width of the entire sheet: A = about 70 mm Front and rear width of the entire sheet: B = about 50 mm Sheet width at the front end of the sheet: C = about 15 mm Notch width on the sheet inner peripheral side: D = about 5 mm Length: E = about 7 mm It should be noted that if the width and / or length of the cut portion is too large, the strength of the sheet in this portion is reduced, and the sheet may be separated into two in use, The sheet may not have sufficient tackiness at this point. On the other hand, if the size of the cut portion is too small, the sheet cannot be properly adjusted to the three-dimensional shape of the denture base, and wrinkles may occur at this part when the sheet is applied on the denture base. For this reason, the width D of the cut portion on the inner peripheral side of the sheet
Is preferably in the range of about 1 mm to about 7 mm, and the length E of the cut is preferably in the range of about 2 mm to about 10 mm. However, these preferred dimensions depend on the individual denture. In order to obtain a shape corresponding to each denture having a different bending ratio, it is desirable to increase the size of the cut portion as much as possible under the above-described conditions.

The lower jaw sheet 10 having such a shape
Can be prepared from a raw sheet (for example, about 1 mm thick) obtained by mixing and kneading denture stabilizers such as polyethylene oxide and carmellose sodium and rolling the mixture. As the denture stabilizer, other various polymer materials having tackiness in a wet state can be used. For example, sodium alginate and polyvinyl alcohol can be used. In addition, polypropylene glycol, methoxyethylene maleic anhydride copolymer and the like can also be used.

The lower jaw sheet 10 may have a layer structure in which a powder denture stabilizer is held between a pair of cloths provided as a support. When a pair of upper and lower cotton nonwoven fabrics is used as the support, a good wearing feeling in which the oral mucosal irritation is reduced physically and chemically can be obtained.

Such a sheet 10 is formed, for example, by laminating an adhesive cloth for forming a resin layer on a cotton non-woven fabric having a thickness of about 0.1 mm to about 1 mm, A denture stabilizer is deposited at a predetermined thickness, and a cotton nonwoven fabric having a thickness of about 0.1 mm to about 1 mm is further laminated thereon, and the layer is sandwiched between rollers and heated and pressed to form a sheet having a layer structure. A denture stabilizer is obtained. In this denture stabilizing sheet, the denture stabilizer is held between a pair of cotton nonwoven fabrics joined by a resin layer at least partially fused. The fusion of the resin layer may be in any form, either entirely or in a dispersed manner (scattered spot, grid, etc.). As the bonding cloth (resin layer material), various materials that melt at a relatively low temperature can be used as long as the use in the mouth is safe. In addition, it is also possible to join the upper and lower cotton nonwoven fabrics by needle punching without using a bonding fabric and providing a resin layer.

As the denture stabilizer, as in the above embodiment,
Various polymeric agents that exhibit tackiness in the wet state can be used, such as polyethylene oxide, sodium carmellose, sodium alginate, polyvinyl alcohol, or mixtures thereof.

In any of the above forms, a pH adjuster such as sodium phosphate, sodium acetate or sodium citrate may be added to the denture stabilizer. This can reduce the possibility that the drug will irritate the oral mucosa.

Alternatively, the sheet-type denture stabilizer 10 for the lower jaw
Can be made from a dry cotton non-woven fabric impregnated with the agents described above.

The sheet-shaped denture stabilizer formed in various forms as described above can be obtained by a known method, for example, as shown in FIG.
Can be cut into various shapes corresponding to the U-shape of the attachment surface of the mandibular denture, such as the mandibular sheet 10 having the notch 12 shown in FIG.

Hereinafter, a method of using the lower jaw sheet 10 of the present embodiment will be described.

First, the lower denture sheet-type denture stabilizer 10 is immersed in warm water or water. Then, the wet sheet 10 is stuck on the denture attachment surface 20 of the well-washed lower denture (FIGS. 2A and 2B). Note that FIG. 2A shows the direction in which the sheet 10 is attached to the mandibular denture in the mounting posture on the ridge, and FIGS. 2B and 2C show the state when the sheet is actually attached to the denture attachment surface (the denture is (Upside down state).

Here, the wet lower jaw sheet 10 is
By having the cut-out portion 12, the inner peripheral side and the outer peripheral side of the U-shape are easily made to have a three-dimensional angle, so that it is easy to match the groove shape. In addition, in the distal end portion 20c of the denture, for example, the side edge 12a of the cut portion 12 is brought closer to different lower jaw dentures having various bending degrees,
By laminating or sticking them apart, the degree of bending of the sheet can be changed so as to correspond to each degree of bending. As described above, since the lower jaw sheet 10 has the strongest curve, the denture tip 2 which is particularly apt to wrinkle when trying to follow a flat sheet is used.
At 0c, it can be easily applied without wrinkling (FIG. 2C).

The lower jaw sheet 10 of the present embodiment, which is stuck on the artificial tooth attachment surface 20 in this manner, is integrally formed so that the entire shape corresponds to the shape of the artificial tooth attachment surface, so that it is easy to use. Yes, and can provide a relatively large tacky surface. Therefore, the denture can be stably fixed to the ridge (contact surface with the denture such as the gum or palate). In addition, if the lower jaw sheet 10 has an extra portion protruding from the denture attachment surface 20, it is desirable to cut off this portion in advance with scissors or the like.

After attaching the lower jaw sheet 10 on the denture attachment surface 20 as described above, the denture is fitted to the ridge, and the denture is chewed until it is fixed. Since the lower jaw sheet 10 of the present embodiment does not form wrinkles and is attached to the denture attachment surface with a substantially uniform thickness, the denture and the ridge can be satisfactorily joined. . Also, even if notch 1
Even if the sheet is pasted in a form in which the two side edges 12a overlap, the sheet is relatively uniformly adhered on the denture attachment surface as a whole, so that a good fixing action and a feeling of wearing can be obtained. obtain.

In this embodiment, the sheet-type denture stabilizer for the lower jaw has a wedge-shaped notch in the center as shown in FIG. 1, but this notch may be formed in various shapes such as a semicircle and a rectangle. Shape.

[0032]

As described above, the seat-type denture stabilizer for lower jaw of the present invention has a substantially U-shaped planar shape, and is three-dimensionally properly aligned with the attachment surface of the denture for lower jaw forming a groove structure. I do. As described above, the sheet-type denture stabilizer can be attached to the denture attachment surface of the mandibular denture without forming wrinkles, particularly at the central portion in the width direction of the U-shaped inner peripheral side sheet. Can be stably and firmly fixed to the ridge, and a good wearing feeling can be obtained.
