Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a working model making device that can be attached to an articulator by adding plaster to a multi-row model.

Conventionally, a rubber tray has been used as this type of production device, but the working model made with this tray is attached to the articulator with plaster, so it cannot be easily removed, and if it is removed, it will not work properly. It is difficult to reattach it to the same position on the articulator, which is extremely inconvenient for examinations and technical operations on the articulator.

The present inventor has developed a production device that can produce a working model whose bottom part can be separated by magnetic adhesion, and the working model made with this device can be attached to the articulator with plaster, except for the bottom part. The device can now be easily attached and detached, and the above problem has been successfully solved.

That is, the present invention provides a rubber tray with an opening at the bottom, which allows a working model to be attached to an articulator by adding plaster to a dental model.
The present invention provides a dental work model maker comprising a synthetic resin plate that can be fitted into the opening of the rubber tray and has a magnet embedded in its surface.

In the present invention, when adding plaster to the dentition model to create a working model to be attached to the articulator, dowel pins are erected on the dentition model, and then one drop of plaster is added, and specific teeth are removed from the dentition model. This also includes making a working model that can be taken out. Furthermore, the dentition model also includes a model of a partial dentition. The synthetic resin plate forms the lower part of the working model, and in order to magnetically attach the separated upper part to a fixed position again, it is desirable to form protrusions or grooves on the surface.

Hereinafter, the present invention will be explained based on examples with reference to FIGS. 1 and 2.

The manufacturing device of the present invention consists of a rubber tray 10 having an opening 11 in the bottom 8101, and a synthetic resin plate 20 having a lid 21 that can be fitted into the opening ill of the rubber tray 10. The rubber tray 10 is made by adding plaster 40 to a dentition model 80 to make a working model to be attached to an articulator, which will be described later.
The shape is similar to that of a conventional rubber tray except for the provision of a rubber tray. The size of the surface 201 of the synthetic resin plate 20 does not matter as long as the lid 21 can fit into the opening 11 of the rubber tray 10;
A magnet 22 is embedded in 1, and a protrusion 28 is provided.

Therefore, the synthetic resin plate 20 is placed in the opening 11 of the rubber tray 10.
The lid part 21 is fitted, the iron piece 41 is magnetically attached to the magnet 22 embedded in the surface 201, plaster 40 is poured in, and the tooth row model 80 with the dowel pin 81 is placed on top of the iron piece 41. By curing, a working model consisting of the tooth row model 30, plaster 40, and synthetic resin plate 20 is completed.
It can be separated from the plaster mold 40 with the iron piece 41 attached to it, and even when it is magnetically attached again after separation, the protrusions 23 on the surface of the synthetic resin plate 20 fit into the plaster 40, so there is no position shift when magnetically attached. There isn't. By attaching the back side 202 of the synthetic resin plate 20 (which has a shape that makes it easy to adhere to plaster) to the articulator (not shown) with plaster, it can be easily attached and detached and reattached in an accurate position. A model can be provided.

Another embodiment of the invention is shown in FIGS. 8 and 4. That is, the dental work model maker in this example includes a rubber tray 10B having an opening 11B in the bottom 101B;
A magnet 22B embedded in the surface 201B of the lid 21B1 that can be fitted into the opening 11B of the rubber tray 10B.
and a synthetic resin plate 20B having grooves 2BB bored on the surface 201B. The effects of this embodiment are the same as those of the embodiment shown in FIGS. 1 and 2, so a detailed explanation will be omitted.
