In the above-mentioned conventional method, it is necessary to make a hole in the base of the impression model and vertically set up the dowel pin, which requires a lot of time and labor for this work. It was a work that required. In addition, in this conventional method, it takes a lot of time and labor to manufacture one dentition model because it follows the process of implanting dowel pins in the impression model and then manufacturing the secondary plaster base. Since it cannot be mass-produced, the cost is high and the delivery time is long.

[0004]

In order to solve the above-mentioned problems of the conventional products, the present invention researches the shape and size of dowel pins, gypsum pedestals, etc., as well as the order of their production in a fairly wide range. As a result, a dental technician having a structure in which a plaster base 2 having a large number of dowel pin insertion holes on the upper surface is inserted into the insertion hole of the plaster base 2 with the dowel pins facing downward. Obtained the removable part of the removable model for dental use, and the dental model removable model in which the bottom of the impression model was adhered to the side opposite to the surface where the dowel pins of this plaster stand 1 were planted I was able to solve all the big problems I had done.
This removable model for dental technicians has a concave portion and a concave portion of the silicone rubber stamp die 1 in which a dowel pin is inserted into a pin hole of a silicone rubber stamp die 1 having a pin hole for inserting a large number of dowel pins on the bottom surface of the concave portion. After injecting gypsum into the dough and hardening it integrally with the dowel pin, the gypsum stand 1 on which the dowel pin is planted is taken out from the silicone rubber stamp 1, and the surface of the obtained gypsum stand 1 and the surface of the dowel pin are coated with a separating agent. After that, the plaster base 1 is set in a concave bottom of a silicone rubber stamp 2 having a recess at a position where the dowel pin faces upward, and then plaster is poured into the recess of the silicone rubber stamp 2 and cured to bond the plaster base 1 together. The gypsum table 2 is formed, and the gypsum table 2 combined with the gypsum 1 is taken out from the silicone rubber stamp 2, and the surface of the gypsum table 1 on which the dowel pins are planted is reversed. It could be produced by adhering the bottom surface of the impression model the surface. Also in the present invention, the same plaster and dowel pin as those in the prior art can be used.
Further, as the separating agent applied to the surface of the plaster mold 1 and the surface of the dowel pin, soap water, a wax pattern, a spartene diluting solution, a water glass aqueous solution or the like can be used as before.

[0005]

According to the present invention, as described above, the dowel pins are planted on the plaster stand 1 with the silicone rubber stamp 1, the separating agent is applied to the surfaces of the plaster stand 1 and the dowel pins, and the dowel pins are transferred to another silicone rubber stamp 2. After filling the plaster around the dowel pin to prepare the plaster stand 2, the impression model is adhered to the surface of the plaster stand 1 to manufacture a removable dental dental model. , It takes a lot of time and labor to open a hole in the bottom surface of the impression model and erect the dowel pin vertically as before, and since the work requiring skill is eliminated, it is very easy to manufacture a dentition model. It became so.

It is a front view of the removable model for dental technique (8) which joined with (7). First, the dowel pin is set in the dowel pin insertion hole of the silicone rubber stamp (1), the primary gypsum kneaded in advance is injected, and after curing, the mold is removed to prepare the gypsum stand 1 (2). Next, the secondary gypsum that had been kneaded in advance was poured into the silicone rubber stamp 2 (5), and the surface of the plaster stand 1 (2) including the dowel pin (3) was coated with a separating agent. With the dowel pin (3) inserted. Furthermore, after hardening this and removing from it to obtain the removable part (7) of the removable model for dental technicians, the upper surface of the plaster stand 1 (2) is made flat with a trimmer,
Separately from this surface, the bottom surface of the impression model (9) made by the dentist was joined with an adhesive to manufacture a removable model (8) for dental technique. This removable model for dental technicians (8)
Is a conventional manufacturing method, that is, a vertical hole is directly formed in the impression model, a dowel pin is set in the hole using an adhesive, and then a separating agent is applied to the lower surface of the impression model including the dowel pin. After that, the manufacturing process is shorter and the work is easier than the method of burying the dowel pin in the silicone rubber stamp mold and burying it in the secondary gypsum, and the work is easier, so even a non-expert can work in a short time. It became so. Subsequently, the part that requires prosthesis of this thing is divided and cut with a thread saw, taken out and taken out, and after the prosthesis work,
As a result of the work of inserting the dowel pin into the dowel pin hole and restoring it to the original model, it was possible to work without problems as with the conventional product.

[0007]

As described above, according to the present invention, first, the plaster stand 1 in which the dowel pins are planted with the silicone rubber stamp 1 is produced, and then the dowel pins are placed in the silicone rubber stamp 2.
It is buried in the secondary plaster, and the plaster base 2 is manufactured to obtain the removable portion of the removable dental dental model, and further joined to the impression model to manufacture the removable dental dental model. But
With this manufacturing method, since the dowel pin planting work that requires special skill unlike the conventional manufacturing method is eliminated,
Now I can work easily and quickly. In addition, in the present invention, the removable part can be made in advance, that is, it can be made ready-made, so all that is left is to join it with the impression model of the order, so the delivery time of the removable model for dental technique is extremely short, and the removable part Since it became possible to mass-produce, it was possible to realize a significant cost reduction.
