Description

  The present invention relates to a dental file in which the early contact portion can be polished and adjusted in the same manner as diagnosing the early contact portion of bite.

  Conventionally, carbon paper has been widely used for diagnosing an early contact portion by examining the occlusal state of teeth. The carbon paper is sandwiched between the upper and lower teeth, and the teeth are strongly abutted against each other or bruised, whereby carbon can be attached to the teeth and the early contact portion can be specified. Further, a dental occlusion inspection sheet as disclosed in Japanese Patent Application Laid-Open No. 04-89047 is known. This is made of pressure-sensitive paper such as carbon paper or pressure-sensitive film, and the occlusal pressure of the parts other than the early contact parts of the upper and lower teeth when biting is close to zero, whereas The occlusal pressure increases and the part develops color. In addition, there is a feature that there is no worry that chemicals such as developer directly adhere to teeth and feel uncomfortable.

  An early contact portion is specified by such a dental occlusion inspection sheet, and this portion is trimmed so that the occlusal pressure is evenly generated on the upper and lower teeth. Until the occlusal pressure is evenly generated, the inspection by the dental occlusion inspection sheet and the grinding of the portion where the occlusal pressure is large are repeatedly performed.

Japanese Patent Laid-Open No. 04-089047 (FIG. 1)

  However, there are many cases where it is often necessary to repeatedly perform inspection and grinding adjustment using the dental occlusion inspection sheet as described above. Therefore, it is the subject of the present invention whether such adjustment work can be performed more easily.

  For this reason, if the paste in which sand is mixed in oil is applied to the part where the occlusal pressure of the upper and lower teeth is high, the patient himself can adjust until the occlusal pressure is evenly generated in the upper and lower teeth. I thought and looked. This makes it possible to facilitate the adjustment work, but this time causes a new problem that the upper and lower teeth are scraped together.

  Therefore, the present invention solves the above problems by providing a dental file comprising a sheet having a file surface on one side for adjusting the early contact portion of occlusion. As the sheet, a plastic sheet, a laminated paper, a metal foil laminated with a plastic film, or the like is used. A filed surface is formed by adhering grindable powder such as ceramic powder or alumina powder to one side of such a sheet. In addition, the kind and shape of a sheet | seat are arbitrary, and the structure of a file surface is also free. Note that it is also possible to provide a plurality of such sheets in a booklet form.

  According to the dental file of the present invention, the portion where the occlusal pressure is large can be ground and leveled by sandwiching between the upper and lower teeth of the early contact portion while the heel is like an occlusal inspection sheet. For this reason, it has the feature that the work of grinding adjustment is speedy.

  The dental file of the present invention may be provided with a gripping portion. By having a dedicated portion as a grip portion, it is not necessary to touch the file portion, and the ease of holding is improved. Further, the gripping part may be provided with anti-slip means. As a result, problems such as slipping with saliva and lowering work efficiency can be reduced.

  The dental file of the present invention may have a sliding surface made of polypropylene or the like on the surface opposite to the file surface of the sheet. In order to prevent the problem that the upper and lower teeth are scraped together as described above, it has a file surface on one side, but if so, the friction between the teeth that hit the surface opposite to the file surface of the sheet is Less is preferable. Therefore, a sliding surface made of polypropylene or the like was provided.

  Further, the dental file of the present invention may be provided with an occlusal inspection unit for diagnosing an early contact portion of occlusion. At this stage, the above-described dental occlusion inspection sheet is useful for knowing whether or not the occlusal pressure has been generated evenly. Therefore, the dental file of the present invention is provided with an occlusal inspection section for this purpose.

  According to the present invention, since it is a dental file made of a sheet having a filed surface on one side for adjusting the early contact portion of the occlusion, the occlusal pressure of the back teeth etc. while the heel is like an occlusal inspection sheet It is possible to grind and smooth the large part, and the effect of speeding up the grinding adjustment work is achieved.

  It is explanatory drawing of 1st Embodiment.   It is explanatory drawing seen from the thickness direction.   It is explanatory drawing of 2nd Embodiment.   It is explanatory drawing seen from the thickness direction.   It is explanatory drawing of 3rd Embodiment.   It is explanatory drawing seen from the thickness direction.

  Hereinafter, three embodiments of the present invention will be described with reference to FIGS. 1 to 6, but the present invention is not limited to these embodiments. 2, 4, and 6, the thickness is exaggerated to clarify the layer structure.

First embodiment

  As shown in FIG. 1 and FIG. 2, the dental file 1 of the present embodiment is obtained by applying an abrasive material of alumina zirconia powder on one side of a support portion 10 that exhibits a thin sheet-like body made of steel with a glue-like adhesive. The filed portion 11 is formed by bonding (not shown) by two-layer coating. Although it does not have special water resistance, it is disposable so there are few problems.

  The dental file 1 of the present embodiment has a configuration unique to the present invention that is used by sandwiching a collar between upper and lower teeth like an occlusal inspection sheet, and a filed portion on the side of a back tooth or the like to be ground in an early contact portion By having the surface of 11 be directed and sandwiched between upper and lower teeth, it is possible to speed up the work of grinding and leveling this part.

Second embodiment

  As shown in FIGS. 3 and 4, the dental file 2 of the present embodiment has a thin sheet-like body made of PP (polypropylene) resin stretched on the back surface of the support portion 20 that presents a thin sheet-like body made of synthetic paper. In combination with the sliding portion 3, a file portion 21 is formed on a part of the surface of the support portion 20, a portion of the support portion 20 not forming the file portion 21 is defined as a grip portion 22, and the slide portion is further formed. 3, the adhesive portion 4 is formed around the grip portion 22.

  A plurality of the dental files 2 of the present embodiment are provided by being bundled in a booklet form with the adhesive portion 4. Therefore, one piece is peeled off at the time of use. Since the adhesive part 4 of the dental file 2 after peeling has a property that it can be lightly adhered to the finger, it can be said that this is a kind of anti-slip means. In addition to this, the anti-slip means may be freely configured, for example, by providing a hole that can be perforated in the gripping part 22 and put the finger skin on it.

  The dental file 2 of the present embodiment has another feature. That is, this portion is ground by sandwiching the dental file 2 between the upper and lower teeth so that the surface side of the file portion 21 is directed to the side of the back tooth or the like to be ground in the early contact portion. In this case, the sliding portion 3 hits the side of the tooth that is not ground. Since the sliding portion 3 is made of PP resin, it has a characteristic that the sliding property with respect to the teeth that are not ground is improved (therefore, the presence of the adhesive portion 4 is significant). In addition, the structure which uses materials with good sliding, such as PP resin, for the support part itself is also possible.

Third embodiment

  As shown in FIG. 5 and FIG. 6, the dental file 5 of the present embodiment forms a file portion 51 on a part of one side of the support portion 50, and the support portion 50 not formed with this file portion 51. A carbon paper portion 6 is formed by pasting red carbon paper on the part.

  The dental file 5 of the present embodiment includes a carbon paper portion 6, and this part is a part used as the dental occlusion inspection sheet described above. That is, the carbon paper portion 6 side is sandwiched between upper and lower teeth, and the red carbon can be attached to the teeth by strongly hitting the teeth with a ticking or bruising. Therefore, after performing the operation of grinding the back teeth or the like to be ground using the file portion 51 side, it becomes possible to check the level of the teeth using the carbon paper portion 6 side. There are features.

  In the dental file of the present invention, the shape of the support portion can be configured as a horseshoe shape or the like so that it can correspond to all the dentitions on both sides at once. Or you may comprise as a horseshoe shape etc. corresponding only to the dentition of one side. Further, in these cases, it is also possible to provide a horseshoe-shaped support part with a separate grip part attached thereto.
