Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dental transfer paper porcelain material for applying opaque porcelain material to a metal coping or a fireproof model, and a method for manufacturing the same.

[Prior Art] In recent years, when a part or several of natural teeth are missing due to diseases such as tooth decay or accidents, it has been carried out to restore them with ceramic artificial teeth, that is, metal-baked porcelain. Metal-baked porcelain is made of porcelain, a dental material (referred to as porcelain), in the parts that touch the exterior, and metal, porcelain-baked heavy alloy crowns (referred to as porcelain) in the parts that have nothing to do with the exterior.
Both parts are baked using metal coping.

Another tooth restoration method is the Beaucelain laminate veneer method, in which a thin shell-like porcelain with a thickness of 0.5 to 0.8 mm is glued onto the tooth surface where the enamel has been removed. It is something to be glued. There are two methods for producing porcelain laminate veneers: the platinum foil method and the fireproof model method.

The platinum foil method is a method in which platinum foil is pressure-contacted to the tooth mold surface of a plaster model to build up porcelain, and then the Beaucelain shell, which has been built up together with the platinum foil, is removed from the tooth mold and fired as it is.The fireproof model method is a method in which silicone After making a reimpression of the tooth impression using a rubber-based impression material, and then injecting a special fire-resistant model material into the re-impression house to create a fire-resistant model, porcelain is directly applied to the fire-resistant model and fired as is. .

In both the metal-baked porcelain and porcelain laminate veneers described above, opaque porcelain is first built up on a metal coping, platinum foil, or refractory model. This opaque porcelain masks the color tone of the alloy or natural teeth and also serves as the base for the color tone of the porcelain itself, and is built up to a thickness of 50 to 200 microns and fired. Thereafter, body porcelain, enamel porcelain, translucent porcelain, etc. are successively built up and fired on top of this opaque porcelain, so that the total thickness of the porcelain is approximately 0.5 to 1.5 mm.

[Problems to be Solved by the Invention] Conventionally, in order to build up opaque porcelain on metal copings or fireproof models, it was necessary to knead porcelain powder with an aqueous solution, and then apply this porcelain to a brush to apply opaque porcelain on metal copings or fireproof models. It is applied to the surface and built up. However, as mentioned above, the opaque layer has a density of 50 to 200
The conventional method of building up opaque porcelain on a metal coping or fireproof model using a brush or spatula at a thickness within this range not only requires skill, but also varies in thickness depending on the part of the tooth. to make
For example, it is extremely difficult and almost impossible to build up the m-plate part to be thick and the incisal part to be thin.

The present invention has been made in view of the above-mentioned problems when building up opaque porcelain on metal copings or fireproof models in metal-baked porcelain or porcelain laminate veneers, etc. An object of the present invention is to provide a porcelain material with a single tooth, which can be built up with a desired change, and a method for manufacturing the same.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present inventors have made it possible to easily apply porcelain to a desired thickness using a method other than applying plaster-like porcelain in a brush. We have conducted extensive research on methods that can be used to build up shapes.

As a result, instead of directly building up porcelain scraps, we first came up with the idea of using a transfer paper with porcelain printed with the desired thickness and shape on a mount using copperplate printing techniques, and completed the present invention.

The transfer paper porcelain material using copperplate printing of the present invention consists of a mount for transferring the porcelain material, and a porcelain material transferred to the mount in the developed shape of the built-up part using the technique of copperplate printing. The gist is:

Further, the method for making transfer paper porcelain using copper plate printing according to the present invention includes a step of applying a brazing material to a copper plate, a step of removing the brazing material in accordance with the developed shape of the built-up portion, and a step of applying a brazing material to the copper plate. etching and forming a recess in the part from which the brazing material has been removed in the step, filling the recess of the copper plate with porcelain, and pressing a mount on the copper plate to transfer the porcelain in the recess. The gist is that it consists of the following steps:

The mount for transferring porcelain supports the printed porcelain and allows the porcelain to be transferred to the metal coping or fireproof model surface without any problems, so it has suitable wettability and excellent strength and flexibility. For example, it is preferable to use Japanese paper or the like.

A conventionally known copperplate printing technique can be used to form the recesses to be filled with porcelain in the copperplate. That is, a brazing material is applied onto a copper plate, the brazing material is removed in a desired shape and depth using hand engraving or photolithography, and then recesses are formed by etching.

The shape of the recess can be any suitable shape, as shown in FIGS. 1(a), (b), (e), and (d), depending on the developed shape of the built-up portion. Further, the depth of the recess can be varied as necessary. That is, FIGS. 1(a), (b), (c), and (d) show a plan view and a cross-sectional view of the state in which the porcelain material 10 has been transferred to the mount 12.
The tooth neck can be thickened as shown in Figure 1 (a), or the tooth neck can be thickened as shown in Figure 1 (b).
) as shown in Figure 1(e), the adjacent parts on both sides can be made thicker as shown in Figure 1(d), or the adjacent parts on both sides can be made thinner as shown in Figure 1(d). can.

The porcelain to be filled into the recesses formed in the copper plate is mixed with an appropriate solvent and binder, and the mixture is applied onto the copper plate and the excess porcelain is scraped off. A mount such as Japanese paper is placed on top of the copper plate whose recesses are filled with porcelain, and the porcelain is transferred to the mount by pressing it down with a roller or the like.

[Function] The dental transfer paper porcelain material using copperplate printing of the present invention transfers the porcelain material to the mount using the technique of copperplate printing, so the desired thickness can be adjusted according to the developed shape of the built-up part. The porcelain material can be transferred onto the mount with the desired thickness and, if necessary, a desired change in thickness. By pressing this transfer paper porcelain against the metal coping or the m-height portion of a fireproof model and peeling off only the mount, it is possible to build up the porcelain in a desired shape quickly and reliably without requiring any skill.

In addition, the method for manufacturing transfer paper porcelain using copperplate printing of the present invention includes the steps of applying a brazing material to a copperplate, removing the brazing material in accordance with the developed shape of the built-up portion, and etching the copperplate. Forming the recesses to be filled with porcelain on the copper plate First, by filling the recesses of the copper plate with porcelain, it is possible to fill the recesses with porcelain of the desired shape and thickness. can. By pressing the mount onto the copper plate whose recesses are filled with porcelain, the porcelain in the recesses can be transferred to the mount.

[Example 1] An example of the present invention will be described to clarify the effects of the present invention.

Subsequently, the brazing material on the copper plate was removed by hand carving in accordance with the developed shape of the opaque porcelain built-up portion of the metal coping 14 as shown in the side view of FIG. This copper plate was corroded using a ferric chloride solution to form a recess 18 with a depth of 100 μm in the copper plate 16, as shown in the cross-sectional view of FIG.

After completely removing the wax remaining on the surface of the copper plate, opaque porcelain powder is kneaded with a special liquid and molasses, and this kneaded porcelain material 10 is applied onto the copper plate and filled into the recesses 18 to remove any excess porcelain. The wood was scraped clean. Next, as shown in Figure 3, Japanese paper is placed on the copper plate as a mount 12, and pressed through a roller, the porcelain material 10 filled in the recesses 18 of the copper plate 16 is transferred onto the Japanese paper to form a transfer paper ceramic. Material 20 was prepared.

The porcelain material 10 of the transfer paper porcelain material 20 made of TJ4 was pressed against the built-up portion of the metal coping 14, and pressed uniformly with a soft bee or fingertips to make it adhere. Next, mount 12
When the porcelain material 10 was peeled off from the porcelain material 10, the part of the porcelain material 10 protruding from the 0 area pasted on the metal coping 14 was corrected with a knife, scissors, a brush, a scraper, etc., and then placed in a heating furnace and heated under reduced pressure. When fired at 900 to 920° C., an opaque layer 22 with a thickness of 80 μm could be formed.

As shown in the cross-sectional view of FIG. 3, ceramic porcelain 24, body porcelain 26, enamel porcelain 28, and lance-lucent porcelain 30 are sequentially built up and fired on the formed opaque layer 22 to form metal-baked porcelain. Completed 32. When this metal-baked porcelain 32 was compared with the conventional one, it was confirmed that it was comparable in color and gloss.

(Example 2) A recess 18 with a depth of 80 μm was formed in the copper plate 16 in the same manner as in Example 1 to match the shape of the opaque built-up part of the fireproof model 34 for porcelain laminate veneer shown in FIG. 5.1 After filling the recess 18 with the opaque porcelain 10 in the same manner as shown in Example IA1, the mount 12 is
Transfer paper porcelain material 20 was prepared by transferring the material to the paper.

X11! ! The porcelain material 10 of the transferred paper porcelain material 20 was pressed against the built-up portion of the fireproof model 34, and pressed uniformly with a soft bald knife or fingertips, etc., to bring it into close contact. Subsequently, only the mount 12 was peeled off from the porcelain material 10, and the porcelain material 10 was adhered to the built-up portion of the fireproof model top 34.

Any parts that protrude from the periphery should be touched up with a knife, scissors, brush, brush, etc., then placed in a heating furnace and heated to 900-920℃ under reduced pressure.
When fired, an opaque layer 22 with a thickness of 50 μm could be formed.

On the formed opaque layer 22, ceramic porcelain, body porcelain, enamel porcelain, and lance lucent porcelain were successively built up and fired to complete a porcelain laminate veneer with a thickness of 0.8 m. When this Bo-Shichishin laminate veneer was compared with the conventional one, it was confirmed that it was comparable in terms of color and gloss.

[Effects of the Invention] As explained above, the dental transfer paper porcelain material using #I plate printing of the present invention includes a mount for transferring the porcelain material and a mount that is built up using a copperplate printing technique on the mount.
