BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view schematically showing a dental orthodontic appliance according to an embodiment of the present invention and teeth of a patient who is inserted into a tooth by a dental orthodontic appliance; FIG. In the present invention, a calibrating device inserted into a mandibular tooth will be described as an example. However, the orthodontic appliance according to the embodiment of the present invention is not limited to this, and may be manufactured to be inserted into the maxillary teeth of the subject.

Referring to FIG. 1, a dental orthodontic appliance according to an embodiment of the present invention may include a main body 110 and a fixing pin 140.

The main body 110 has a tooth insertion portion 120 into which a mandible tooth is inserted and a tooth seating portion in which an upper tooth is seated on the opposite side of the tooth insertion portion 120.

The tooth inserting portion 120 is formed in the shape of the mandible 10 as a portion into which the mandible 10 of the subject is inserted.

The tooth seating portion is a portion where the maxillary teeth of the recipient are seated, and the shape of the longitudinal section of the maxillary teeth is formed with a negative angle. The tooth seat is used to cut the maxillary teeth and food.

The main body 110 is made of heat polymerization resin, and when the resin is cured, the main body 110 is cured by the high heat in the gypsum mold and becomes high in strength.

The fixing pin 140 is fixed to the tooth inserting portion 120. The fixing pin 140 is formed of a metal. The fixing pin 140 is coupled to the teeth of the mandibular teeth 10 to fix the main body 110 to the mandibular teeth 10. The number of the fixing pins 140 may vary depending on the condition of the teeth of the subject.

As described above, the dental orthodontic appliance according to the embodiment of the present invention is fixed to the mandible and can perform a function of a calibrating device such as a jaw joint correction. In addition, the orthodontic appliance can be used to cut food together with the maxillary teeth because of its high strength using thermal polymerization resin.

2 is a flowchart sequentially illustrating a method of manufacturing a dental orthodontic appliance according to an embodiment of the present invention.

2, a dental orthodontic appliance manufacturing method according to an embodiment of the present invention includes a tooth bone forming step S100, a metal pin forming step S200 on a tooth bone, a step S300 after forming a parison on a tooth bone, ), A first heating step (S400), a resin forming step (S500), a second heating step (S600), and a gypsum separation step (S700).

Specifically, the tooth pattern forming step (S100) produces tooth patterns using alginate and gypsum commonly used in dentistry. The toothbrush produces a maxillary tooth pattern and a mandibular tooth pattern, respectively.

The metal pin formation step (S200) on the tooth bone forms a metal pin to be used in the orthodontic appliance in the tooth bone. As shown in FIG. 3, a metal pin 220 is formed between the teeth of the mandibular tooth pattern 200. At this time, one end of the metal pin 220 may be formed into a spherical shape to be inserted into the inter-tooth space. The other end of the metal pin 220 is preferably rounded so as not to cause a wound in the oral cavity of a patient who wears the orthodontic appliance.

After the paraffin is formed on the tooth bone, the occlusion step (S300) forms paraffin with a predetermined thickness on the mandibular tooth pattern so as to cover the metal pin, and aligns the maxillary and mandibular joints through the articulator. The paraffin (250) is located between the maxillary and mandibular teeth, and the tooth shape of the maxillary tooth pattern is formed in the gypsum in the next step.

Fig. 4 is a view showing a state in which paraffin is formed on the mandibular tooth pattern after occlusion. Fig. As shown in Fig. 4, the upper surface of the paraffin 250 forms a tooth shape of the upper teeth.

Thereafter, a mandibular tooth pattern in which the paraffin is formed is provided in a mold.

In the first heating step (S400), the mold having the mandibular tooth pattern is firstly heated. Before the heating, the area around the mandibular teeth in the lower molding die, where the lower dental pattern of the molding die is installed, is plastered with gypsum. Next, a gypsum solution is formed so as to cover the mandibular tooth pattern in the lower mold, and then the upper mold is covered with the solution. Here, a gypsum separating agent is evenly applied to the upper surface of the mandibular tooth pattern provided on the lower molding die, and then the gypsum solution is formed to easily separate upper and lower portions of the molding die. The mold is allowed to stand for a predetermined time until the internal gypsum is cured, and then the primary mold is heated.

In the first heating, the mold is put into boiling water and heated for several to several tens of minutes. The paraffin in the mold is melted through the primary heating.

In the resin forming step (S500), the primary heated molding die is separated, and the remaining paraffin is removed from the upper molding die and the lower molding die, and resin is formed on the tooth base of the lower molding die. Resins use thermally polymerized resins that have the property of being cured by reaction by thermal polymerization.

As shown in FIG. 5, the resin 280 is formed so as to cover all the teeth of the tooth pattern 200, as in the case of forming the paraffin on the tooth pattern 200 of the lower forming mold 410. The separating agent is applied so that the resin 280 is easily separated from the tooth pattern 200 before the resin 280 is formed.

The separating agent is applied to the exposed front surface of the tooth base 200 of the lower forming mold 410 and the region where the resin 280 is adhered to the upper forming mold.

Subsequently, the upper molding die and the lower molding die are closely contacted and subjected to secondary heating.

On the other hand, prior to the second heating, a high pressure is applied to the mold using a pressure device. Use a pressure device to ensure that the resin in the mold is in close contact with the tooth bone and the gypsum in the upper mold. In particular, a high pressure is applied to penetrate the resin between the tooth bone and the metal pin, so that the metal pin binds to the resin after the resin is cured.

In the second heating step (S600), the mold is immersed in boiling water to heat the same as in the first heating step (S400). The heating time may range from several minutes to several tens of minutes and may proceed until the thermal polymerization reaction of the resin 280 is completed.

The strength of the resin is increased by the secondary heating to have gloss.

Next, the mold is taken out, cooled, the mold is separated, and the gypsum and tooth pattern are separated from the resin.

The gypsum separation step S700 separates the gypsum and the tooth pattern from the resin to complete the dental orthodontic appliance 100 shown in Fig. At this time, the metal pin 220 formed on the tooth base 200 of FIG. 3 is attached to the resin and serves as a fixing pin 140.

As described above, in the dental orthodontic appliance according to the embodiment of the present invention, the metal pin attached to the resin is fixed to the teeth when worn. At this time, since the thermal polymerization resin used in the orthodontic appliance can be heated in the gypsum mold to increase the strength, it can be chewed in place of the normal teeth.

In addition, when the teeth are cut, the cutting surface is not exposed by the above-described orthodontic appliance, so that the progress of wear can be prevented.

In addition, the face is made long to make the chin line of the person to be tapered, and the volume of the orthodontic appliance causes the wrinkles of the maxillofacial region to spread.
