FIG. 9 is a view showing a state in which a tooth model of an upper and lower teeth is supported on a joint link device FIG. 10 is a perspective view illustrating a state in which a tooth model of the maxillary and mandibular teeth is opened by a joint link device in an aligned state of an occlusal relationship, FIG. 11 is a perspective view illustrating a state in which the core frame 120 is formed 12 is a perspective view illustrating a state in which the retaining member 200 is disposed on the core frame 120 and FIG. 13 is a perspective view illustrating the state in which the pocket frame 100 is formed on the core frame 120. FIG. Fig. 7 is a perspective view showing a state in which the layered structure is covered.

Referring to FIG. 8, the method for manufacturing the mouth guard 10 includes the steps of applying a hard resin to be a core frame 120 on a teeth model, molding the core frame 120, And forming a pocket frame (100) forming a tooth receiving pocket outside the core frame (120), wherein the step of disposing the retaining member (200) so as to cover a tooth requiring a holding force.

The positioning of the retaining member 200 may be performed before the core frame 120 is cured after the resin is applied or after the core frame 120 is cured.

The manufacturing process of the mouth guard 10 according to the present embodiment will be described in more detail with reference to FIGS. 8 and 9 to 13. FIG.

In the method of manufacturing the mouth guard 10 according to the present embodiment, the core frame 120 is manufactured on a tooth model. To this end, a tooth model of a user, for example, an oral gypsum model is prepared. The tooth model is generally manufactured using an impression material and a gypsum. Since the method of manufacturing the tooth model is generally known in the art, further explanation is omitted.

The tooth model has the same structure as that of the teeth to which the mouth guard 10 is attached. Hereinafter, the tooth model that mimics the tooth, that is, the structure of the tooth to which the mouth guard is attached, is called a first tooth model M1, and the tooth model that mimics the structure of a relative tooth is called a second tooth model M2.

9 and 10, in order to manufacture the tooth frame, particularly the core frame 120 on the first tooth model M1, the first tooth model M1 is attached to the base plate < RTI ID = And the occlusion relationship of the first tooth model M1 and the second tooth model M2 is arranged on the base plate P as much as the occlusal relationship of the wearer's upper and lower teeth.

In order to arrange the interlocking relationship of the first tooth model M1 and the second tooth model M2, a dental bite having teeth marks on the lower and upper teeth of the wearer can be used.

A link bar L is rotatably connected to the joint J of the articulated link mechanism in a state where the first tooth model M1 and the second tooth model M2 are aligned. The second tooth model M2 is fixed. 10, when the link bar L is rotated about the joint J after the second tooth model M2 is fixed to the link bar L, The first tooth model M2 is spaced apart from the first tooth model M1 while rotating.

Next, as shown in FIG. 11, the core frame 120 may be manufactured on the first tooth model M1, and the core frame 120 may be formed on the first tooth model M2, It is manufactured by applying dental resin, especially hard resin, to the tooth part of tooth model and hardening it. Of course, the core frame 120 may be manufactured by stamping a hard sheet to be described later on the first tooth model M1.

In other words, the core frame 120 may be formed by applying a dental resin, particularly a hard resin, to a tooth portion of the first tooth model or by placing a hard sheet on the first tooth model M1, .

In this embodiment, a dental resin, more specifically, Methyl Methacrylate and Polymethyl Methacrylate are applied to the tooth portion of the first tooth model M1, 120 are formed into a shape having the tooth contact surface 121 described above. Of course, it is also possible to form the core frame 120 by stamping a hard resin sheet on the first tooth model M1.

The core frame 120 may be completed by finishing the outer surface of the core frame 120, for example, by trimming a surface and an edge of the core frame 120.

Referring to FIG. 12, after the core frame 120 is formed, the retaining member 200 is disposed such that the end of the retaining member 200 is positioned on the surface of the formed core frame 120 The rest of the retaining member 200 is disposed so as to surround the outermost tooth (e.g., the maxillary second molar) of the first tooth model.

In this way, the retaining member 200 disposed on the first tooth model M1 encloses the morphological limit of the tooth and the outermost tooth (e.g., the maxillary second molar) with insufficient eruption, And its end can be fixed between the core frame 120 and a pocket frame 100 described later.

13, after the molding of the core frame 120 and the disposition of the retaining member 200 are completed, the manufacturing process of the pocket frame 100 proceeds.

In order to manufacture the pocket frame 100, the core frame 120 and the retaining member 200 are disposed on the outer side of the core frame 120 in a state where the core frame 120 and the retaining member 200 are disposed on the first tooth model M1. The layered structure S for the pocket frame 100 is molded so that the retaining member 200 is embedded between the core frame 120 and the pocket frame 100. [

The pocket frame 100 may be completed through a process of finishing the appearance, for example, a trimming process of finishing the surface and the edge of the pocket frame 100.

14, the retaining member 200 may be disposed before molding the core frame 120 , that is, in a resin-applied state for forming the core frame.

That is, referring to FIG. 14, a teeth model is arranged, the occlusal relationship of the tooth model is aligned, and then the resin is applied to the tooth model. At this time, at least one end of the retaining member 200 is buried in the resin, and the remaining portion of the retaining member 200 is in contact with the outermost tooth (e.g., a tooth) along the dental arch of the first tooth model. Maxillary second molar).

Then, the core frame 120 is formed. In this way, the end of the retaining member 200 is fixed in a state embedded in the core frame 120.

The layered structure S may be formed by sequentially laminating a soft layer and a hard layer on the outer side of the core frame 120 to form a layered structure S, The layered structure (S) can also be formed by using the multi-layer sheet integrated with the multi-layer structure.

More specifically, the retaining member 200 is configured to surround the outermost tooth (e.g., the maxillary second molar) having a morphological limit on the first tooth model M1 and a lack of eruption. And then the soft layer and the soft layer laminated on the hard layer and integrated with the hard layer (for example, model name TRACK B, manufactured by FORESTADENT, Germany) are softened. Then, the first tooth model M1 on which the core frame 120 is disposed is transferred to the second tooth layer at a negative angle, Layered sheet is integrated on the outside of the core frame 120 by adhering it to the model M1 by suction or pressurization.

Examples of the material constituting the hard layer include PETG material, and examples of the material constituting the soft layer include EVA material and TPU material, but the specific material is not limited to the above-mentioned kind.

The model name TRACK B of Germany FORESTADENT, which is an example of the above-mentioned multilayer sheet, can be softened by heat. When the multilayer sheet is stamped on the first tooth model M1 in which the core frame 120 is disposed, Can be molded. The layered structure S described above can be manufactured using a thermocompression transfer apparatus (for example, TRACK, model name of FORESTADENT, Germany).

On the other hand, referring to FIG. 15, instead of using a multi-layer sheet, a hard layer made of a soft sheet and a hard layer made of a soft sheet may be sequentially laminated to form the layered structure S.

More specifically, the layered structure may be fabricated by forming a soft inner cover layer 102 and forming a hard outer cover layer 101 outside the inner cover layer 102 .

Thus, in the state in which the inner cover layer 102 is formed, the retaining member (not shown) is provided to surround the outermost tooth (e.g., the maxillary second molar) having the morphological limit on the first tooth model M1 or lack of eruption The inner lining layer 102 may be formed to dispose the retaining member 200 so that the retaining member 200 is not exposed to the outside.

The inner cover layer 102 is formed on the inner surface of the inner cover layer 102 so that the shape of the first tooth model M1 in which the core frame 120 is disposed is a soft sheet The soft sheet is adhered to the first tooth model M1 on which the core frame 120 is disposed so that the core frame 120 and the soft sheet are integrally formed .

The outer cover layer 101 may be formed in the shape of the first tooth model M1 covered with the core frame 120 and the soft sheet such that the shape of the outer cover layer 101 is a hard hard sheet The hard sheet is brought into close contact with the first tooth model M1 covered with the core frame 120 and the soft sheet so as to be transferred to the outer side of the soft sheet, And the hard sheet is integrated with the hard sheet.

The process of forming the outer cover layer 101 and the inner cover layer 102 can also be performed using the above-described thermocompression transfer apparatus (for example, TRACK, model name of FORESTADENT, Germany).

Both the hard sheet and the soft sheet as well as the above-mentioned double-layer sheet are thermoplastic, softly softened when heat is applied, and pressed when pressed against the teeth model, and hardened as the shape is stamped.

In a state in which the core frame 120 and the layered structure S are stacked and disposed on the first tooth model M1, the layered structure S is formed in a manner corresponding to the occlusal relationship between the upper and lower teeth The occlusion relationship between the upper teeth T1 and T2 and the lower teeth T3 and T4 is transferred to the outer surface of the pocket frame 100 when the second tooth model M2 is drawn on the outer surface.

The interlocking relationship between the upper and lower teeth transferred to the outer surface of the pocket frame 100 is formed in a state in which the layered structure S is softened, that is, in a moldable temperature state. As shown in FIG. 13, 9 and 10) of the articulated link device is rotated downward while the model M1 is covered with the core frame 120 and the layered structure S, When the tooth is pressed by the second tooth model M2, the tooth part of the second tooth model M2, in particular the tip of the tooth, is transferred to the surface of the layered structure S.

Thereafter, the layered structure S having the retaining member 200 therein is separated from the first tooth model M1, the layered structure S is cut, the surface is trimmed, and the appearance is finished The mouth guard 10 of the arch shape can be completed.

The mouthguard 10 described above may be manufactured using a tooth model of a wearer (user) as described above, or may be a three-dimensional shape of a mouth guard designed on a computer using CAD / CAM And the data may be transmitted to the three-dimensional molding machine to be manufactured in the three-dimensional molding machine. That is, if the retaining member 200 is supplied at an appropriate time based on the three-dimensional shape data in which the components such as the core frame 120 are designed using the tooth image data of the user (patient) 10) may be manufactured through a three-dimensional molding machine.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the appended claims. It is self-evident to those who have knowledge of.

For example, the retaining member 200 may be formed in a band shape having a thin thickness, a predetermined width, and a long length instead of the illustrated wire shape.

In addition, the retaining member 200 may be made of a shape memory alloy capable of deforming so as to apply a retention force to a molar requiring a holding force by the temperature in the oral cavity when worn, ≪ / RTI >
