2. Description of the Related Art In the field of dentistry, in addition to treatment for the purpose of recovering the function of teeth, treatment for restoring natural teeth (usually anterior teeth) whose color tone has changed in recent years is performed for the purpose of improving the aesthetics of the mouth. It started to come. And because the strength of the materials used for these treatments has improved,
The natural tooth with a changed color is also used for the treatment to repair the missing part of the natural tooth (whether anterior or posterior) that previously used a non-crown colored member such as amalgam or composite resin. The materials used for treatment have come to be used as they are.

In the treatment for repairing such a tooth, first, a natural tooth whose color tone has been changed or a part of which is missing is to be restored, and the enamel which constitutes the outermost shell of this tooth is necessary. Accordingly, a predetermined portion of the dentin (in the illustrated embodiment, almost the entire surface of the enamel exposed on the front side) is cut to a predetermined thickness as shown in FIG. 5 (only the enamel is removed by cutting as in the illustrated embodiment). In some cases, a relatively thin thickness) is removed by cutting to obtain an impression of the cut tooth 6, and then a tooth restoration laminate having a shape and a color tone suitable for the tooth 6 is produced. It is a treatment of adhering the restoration laminated body to the cut portion of the tooth. As a treatment for repairing this tooth, the illustrated embodiment is a case of laminated veneer, but it is also a case of crown or inlay.

In the above-mentioned laminated body for tooth restoration, tooth restoration members such as dentin, enamel and translucent are laminated in a desired thickness and shape, for example, with dentin as a lower layer, enamel as a middle layer and translucent as a surface layer. When a tooth color change to be restored by tetracycline or the like is remarkable, tooth restoration members such as masking dentin, masking cervical, and masking modifier, etc. may be used in addition to the above-described tooth restoration member as necessary. It is laminated on the lower layer of dentin forming the lower layer.

Here, as the tooth restoration member constituting the tooth restoration laminate, various tooth shades having slightly different color tones are prepared for each member, and a tooth restoration member corresponding to these various color tones is prepared. Color swatches are ready,
A tooth restoration member having an optimum color tone is selected and used in correspondence with a different color tone depending on the patient and individual teeth. That is, as described above, the tooth to be restored and the tooth adjacent to this tooth are different depending on the patient,
In order that the restored tooth and the tooth adjacent to this tooth are in harmony with each other, the tooth restoration member having the color tone most suitable for the tooth to be restored by the operator is provided with the color sample of the tooth restoration member and the tooth to be restored and It is possible to make a selection while comparing the color tone of the tooth adjacent to this tooth.

The color sample of the above-mentioned tooth restoration member has a circular shape, a quadrangular shape or a combination thereof, and has an area of
10 mm ² ～350Mm is formed on the ^second plate member, conventionally it had been adhered to the color sample adhered board made of opaque material.

However, as described above, the dental restoration laminated body adhered to the tooth to be restored has a transparent or translucent enamel which constitutes the outermost shell of a natural tooth and, if necessary, dentin. Since it is used instead, the tooth restoration member is also a transparent body or a translucent body, and when these tooth restoration members are laminated to manufacture a laminated body for tooth restoration, it matches the desired transparency. Despite the importance of selecting the member, the color sample of the tooth restoration member attached on the color sample sticker plate made of an opaque material is in a state in which the transparency is hardly judged. It is difficult to select a tooth restoration member, and the impression and texture of the tooth restoration laminate expected by the operator is the impression of the tooth tone that was actually restored by adhering to the cutting part and making the tooth restoration laminate. And different compared to the texture , There is a drawback that it can not repair the tooth color tone and texture of the street think of the operator.

[0008]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned drawbacks of the prior art, and when manufacturing not only a laminated veneer but also a crown or an inlay with a tooth restoration laminate in which tooth restoration members are laminated, When comparing the color tone of the tooth to be restored and the tooth adjacent to this tooth and the color sample of the tooth restoration member, which is the most important factor when selecting the restoration member, the color sample of the tooth restoration member is transparent. Provided is a color sample sticking plate for a tooth restoration member, which can be seen in various states, and which can express the color tone of a tooth restored by adhering a laminated body for tooth restoration in a color tone desired by an operator. This is an issue.

[0009]

DISCLOSURE OF THE INVENTION As a result of intensive studies by the present inventors, a transparent or translucent tooth restoration laminate is adhered to a tooth to be restored as it is. When a tooth restoration member, which is a transparent or translucent body, that constitutes the laminated body for tooth restoration is stuck on an opaque body, it has a color tone and a texture similar to that of an opaque body to judge the difference in transparency between the members. In addition to making it difficult for the tooth to be easily affected by the surrounding color, a predetermined portion of the tooth surface to be restored was cut and removed by a predetermined thickness, and a tooth restoration member was laminated on the cut portion. A tooth restoration member for comparing with a tooth to be restored and a color tone of a tooth adjacent to the tooth in order to determine each tooth restoration member to be used when the laminated body for tooth restoration is adhered and restored to a beautiful state. Tooth to which the color sample of As a color sample sticker plate for the restoration member, the color sample sticking part to which the color sample of the tooth restoration member is stuck is formed of a colorless transparent or milky white translucent material, and the surface excluding this color sample sticking part is The above problem can be solved by forming the color sample to be achromatic and opaque. When the size of the color sample cannot be made the same as the size of the color sample attaching part, the color sample of the tooth restoration member is the color sample attaching part. The maximum gap between the color swatch and the achromatic and opaque surface excluding the color swatch attachment is 2 mm or less, and the area of each color swatch attachment is 1.0 to 1.6 times the area of each color swatch. By doing so, it was also clarified that the gap had almost no effect, and the present invention was completed.

The color sample sticking plate of the tooth restoration member according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view showing an embodiment of a color sample sticking plate for a tooth restoration member according to the present invention, FIG. 2 is a sectional view taken along the line AA in FIG. 1, and FIG. 3 is a structure 1 of a tooth restoration laminate. FIG. 4 is a cross-sectional explanatory view showing an example, and FIG. 4 is a cross-sectional explanatory view showing an example of a tooth to which a tooth restoration laminated body is bonded and restored.

In the drawing, reference numeral 1 denotes a surface of enamel constituting the outermost shell of a tooth 6 to be restored, which is thinly cut and removed by a predetermined thickness, and a tooth restoration member 4a is laminated on the cut portion 7. When a laminated body 4 for restoration of teeth, which is called a laminated veneer, is adhered to restore a beautiful state, or when not only enamel but also dentin is cut and removed by a predetermined portion that is damaged by a touch or the like. In order to determine each tooth restoration member 4a to be used for adhering the tooth restoration laminated body 4 having a function of an inlay or a crown in which the tooth restoration member 4a is laminated to a portion, and to determine each tooth restoration member 4a to be used for restoration, A color sample of the tooth restoration member according to the present invention, to which a color sample 2 of each tooth restoration member 4a described below is attached in order to compare the color tone of the tooth 6 to be power and the tooth adjacent to the tooth 6 with the tooth restoration member 4a. It is a sticker plate.

The tooth restoration member 4a constituting the tooth restoration laminate 4 is used as necessary when dentin, enamel, translucent, tetracycline or the like causes a significant change in the color tone of the tooth to be restored as described above. There are different types of masking dentin, masking cervical, masking modifier, etc., and each type has a slightly different color tone.

Reference numeral 2 is a color sample showing each color tone of the various tooth restoration members 4a. What kind of color sample should be used so long as it can be compared with the color tone of the tooth 6 to be restored and the tooth adjacent to the tooth 6? It may have any shape, but usually has an area of 19 mm ² with a circular shape, a square shape, or a combination of these shapes.
Or (diameter in the case of a circular shape approximately 5mm weak) is formed in a plate-like body, it is preferable to use those 19mm ² ~255mm ^2.

A color sample sticking plate 1 for a tooth restoration member according to the present invention, to which the color sample 2 of the tooth restoration member 4a is stuck.
Since most of the above-mentioned various color swatches 2 have transparency to some extent, the influence of the color tone of the color swatch sticking part 1a when attached to the color swatch sticking part 1a is affected. As it is received, the color sample attaching portion 1a to which the color sample 2 of each tooth restoration member 4a is attached
Is formed of a colorless transparent or milky white translucent material, and the color sample 2 attached to the color sample attaching portion 1a transmits light without being affected by the color tone of the color sample attaching portion 1a. It is necessary to be formed so that it can be seen in the open state. The color sample sticking portion 1a is made to correspond to the size and shape of the color sample 2 as described above.
The shape is determined, and when the color sample 2 of the tooth restoration member 4a is attached to the color sample attaching portion 1a, the color sample 2 and the achromatic and opaque surface 1b excluding the color sample attaching portion 1a It is preferable that the maximum gap 3 is within 2 mm and the area of each color sample sticking portion 1a is 1.0 to 1.6 times the area of each color sample 2. And
As shown in FIG. 1, a plurality of color samples 2 of a plurality of kinds of tooth restoration members 4a are formed on one color sample sticking plate 1 so that the color samples 2 can be stuck according to types and colors. It is preferable that each of the restoration members 4a constituting the laminated body can be selected with the color sample sticking plate 1 of 1.

The surface 1b excluding the color sample sticking portion 1a is a color sample 2
Is composed of an achromatic and opaque plate that is fixed by a fastening material such as a screw or an adhesive to a plate formed of a colorless transparent or milky white translucent material that constitutes the color sample sticking portion 1a Of the achromatic and opaque paint applied to the surface of the plate which is formed of a colorless transparent or milky white translucent material which constitutes the color sample attaching portion 1a to which the color sample 2 is attached. The color sample 2 of the tooth restoration member 4a, which is formed of a film, is not affected by the color tone of the surface 1b except the color sample attaching portion 1a and the color and shape of the substance existing on the back side due to the transmission of light. Is formed so that light can be seen in the state of being transmitted.

[0016]

The colorless and transparent or milky white translucent color sample sticking portion of the color sample sticking plate 1 for a tooth restoration member according to the present invention.
The color sample 2 is attached to 1a, and a colorless transparent adhesive 5 (for example, trade name: Aron Alpha, manufacturer: Toagosei Kagaku Kogyo) is used to attach the color sample 2.

A color sample sticking plate 1 for a tooth restoration member according to the present invention, to which a color sample 2 is stuck using such an adhesive 5.
When the operator compares the color tone of the color sample 2 attached to the color sample attaching plate 1 with the color tone of the tooth 6 to be restored and the tooth adjacent to the tooth 6, the operator attaches the color sample 2 Since the attached color sample sticking portion 1a is colorless and transparent or milky white translucent, the light transmitted through this color sample sticking portion 1a passes through the color sample 2 while the surface excluding the color sample sticking portion 1a Since 1b is opaque, the transmission of light from the back side does not occur on the front side 1b except the color sample attachment section 1a.
On the surface except the color sample sticking part 1a
Since 1b is an achromatic color, the state when the color sample 2 is seen allows the color tone specific to the color sample 2 to be observed in a natural state on the color sample sticking plate 1.

Here, the color sample sticking portion 1a has substantially the same shape as that of the color sample 2 to be stuck, and when the color sample 2 is stuck to the color sample sticking portion 1a, The maximum gap 3 between the achromatic and opaque surface 1b excluding the color sample sticking part 1a is within 2 mm, and the area of each color sample sticking part 1a is 1.0 to 1.6 times the area of each color sample 2 Since there is almost no influence of the light transmitted from the back side on the four sides of the color sample 2, the color sample 2 does not have to be accurately formed in the size and shape of the color sample attaching portion 1a. We have confirmed that there are no problems.

[0019]

As described above in detail, since the color sample sticking plate of the tooth restoration member according to the present invention has only the color sample sticking portion as the permeable portion, it is used in a state where it is originally permeable. By adhering the color sample of the tooth restoration member to the color sample attaching portion, it is possible to observe in a more natural state that is similar to the use state of the tooth restoration member. It is possible to compare the color tone of the adjacent tooth and the color tone of the color sample attached to the color sample attaching part in a state very close to the impression of the color tone of the tooth restoration laminate adhered to the restored tooth. Thus, a tooth restoration member having a color tone that an operator desires can be selected, and its industrial value is very large.
