JPH08123319A - Denture model of baby teeth and its production - Google Patents

Abstract

PURPOSE: To provide a denture model of baby teeth having a high real feel by mounting a removed baby tooth at a cervical base. CONSTITUTION: An existing tray on which a putty-like dental impression material 4a is built up is put into the oral cavity and is pressed to the teeth and the gingiva, by which a preliminary tooth and gingiva model is formed. The dental impression material 4a on which a pasty dental impression material 4b is built up is inserted again into the oral cavity to form the more meticulous tooth and gingiva model 6. The removed baby tooth 1 is inserted into the tooth profile 6a part of the tooth and gingiva model 6 and a cervical material consisting of gypsum or synthetic resin is packed therein. The tooth and gingiva model 6 is removed after solidification of the cervical material, by which the denture model of the baby teeth is obtd.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dentition model for deciduous teeth using a missing deciduous tooth, and a method for manufacturing the dentition model.

[0002]

2. Description of the Related Art A conventional dentition model of milk teeth has been made of plaster. The dentition model of milk teeth made with this gypsum, when all the deciduous teeth are fully grown, create the teeth and gum mold up to the gum part with a dental impression material, pour plaster into this tooth and gum mold and solidify. It was created by removing the tooth / gum mold from the solidified plaster.

[0003]

However, in the above-mentioned conventional dentition model of milk teeth made of plaster, the boundary between the part corresponding to the tooth and the part corresponding to the gum is not clear, and the part corresponding to the tooth is not clear. Since the part corresponding to the gums is the same color, there is no real feeling, even if you have a dentition model of your own deciduous teeth, you can not recognize familiarity, you can only recognize it as a dentition model, and there is no interest at all Had.

Therefore, the present invention has been made to solve the problems of the above-described conventional dentition model of milk teeth.

[0005]

Therefore, in the dentition model of the deciduous teeth of the present invention, the dropped deciduous teeth 1 are arranged on the gum base 2 with the deciduous teeth 1 growing. The gum base 2 can be embodied as gum-colored plaster or synthetic resin.

Further, according to the method for manufacturing the dentition model of the deciduous teeth of the present invention, the step of making the tooth / gingiva mold 6 up to the gum portion when the deciduous teeth 1 are all grown with a dental impression material, A step of inserting the tooth / gum mold 6 into the tooth mold 6a portion of the milk tooth 1 that has fallen out, a step of filling the gum mold 6b portion of the tooth / gum mold 6 with a gum material 8, a step of solidifying the gum material 8; Tooth / gum type 6 is used for deciduous teeth 1 and solidified gum material 8
It is assumed to have a step of removing from.

[0007]

The dentition model of the deciduous teeth of the present invention is provided with the above-mentioned means, so that the boundary between the deciduous teeth 1 and the gum base 2 is clear, and when the gum base 2 is made of gum-colored plaster or synthetic resin, The border between the gum base 2 becomes clearer and a real feeling appears.

Further, according to the method of manufacturing the dentition model of the deciduous teeth of the present invention, the dentition model of the deciduous teeth in which the boundary between the deciduous tooth 1 and the gum base 2 is clear can be produced without using a special device or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The dentition model for milk teeth and its manufacturing method according to the present invention will be described below with reference to the drawings shown as embodiments.

FIG. 1 shows a dentition model of the deciduous teeth of the present invention, where a is a dentition model of the upper deciduous teeth and b is a dentition model of the lower deciduous teeth. These deciduous tooth alignment models are
With the milk tooth 1 that has come off, in the state where the milk tooth 1 has grown, the gum base 2
It is supposed to be arranged in. The milk teeth 1 arranged on the gum base 2 are preferably fixed to the gum base 2, but may be detachable. Further, the gum base 2 is preferably made of gypsum or synthetic resin. Furthermore, the gum base 2 can be embodied as gum-colored plaster or synthetic resin.

Such a tooth alignment model of milk teeth is manufactured through the following steps. First, the putty-shaped dental impression material 4a is raised on the ready-made tray 3 to prepare the upper surface (shown in FIG. 2). And this putty-like dental impression material 4
Put a together with the tray 3 into the oral cavity, press against the teeth and gums,
After the putty-like dental impression material 4a is cured, it is taken out from the oral cavity (shown in FIG. 3). In this step, an approximate tooth / gingival mold 5 is produced from the putty-like dental impression material 4a.

Next, a paste-like dental impression material 4b is laid on the upper surface of the dental impression material 4a (shown in FIG. 4). Then, this is put together with the tray 3 into the oral cavity, pressed against the teeth and gums, and after the paste-like dental impression material 4b is cured, it is taken out from the oral cavity and removed from the tray 3 (shown in FIG. 5). In this step, an elaborate tooth / gum mold 6 is produced from the putty-shaped dental impression material 4a and the paste-shaped dental impression material 4b raised on the upper surface thereof.

Further, the removed milk tooth 1 is pinched with tweezers 7 or the like, and is inserted into the tooth mold 6a portion of the removed milk tooth 1 of the tooth / gum mold 6 (shown in FIG. 6). And the tooth / gum type 6
Gum material 8 made of gypsum or synthetic resin on the gum mold 6b
(As shown in FIG. 7).

Then, after the gum material 8 is solidified, the tooth / gum mold 6 is removed from the deciduous teeth 1 and the solidified gum material 8 to produce a dentition model of deciduous teeth as shown in FIG. .

In this embodiment, as the putty-shaped dental impression material 4a, a high-viscosity putty type of hydrophilic vinyl silicone impression material manufactured by Meta Dental Industry is used, and as the paste-shaped dental impression material 4b, Similarly, a low viscosity injection type hydrophilic vinyl silicone impression material manufactured by Jitsu Dental Industry was used, but the invention is not limited to these and any dental impression material can be used.

[0016]

Since the dentition model of the deciduous teeth of the present invention is configured as described above, the boundary between the deciduous teeth 1 and the alveolar base 2 is clear, and the alveolar base 2 is a gum-colored plaster or synthetic resin. In this case, the boundary between the deciduous teeth 1 and the gum base 2 becomes clearer and a real feeling appears. Therefore, if the dentition model of the milk teeth is one's own, it is possible to observe it as a familiar and interesting thing.

Further, since the method for manufacturing the dentition model of the deciduous teeth of the present invention comprises the steps as described above, a special device for the dentition model of the deciduous teeth in which the boundary between the deciduous teeth 1 and the gum base 2 is clear is provided. Since it can be manufactured without using, the manufacturing cost is not so high and anyone can easily implement it.
