Field of the Invention [0001] The present invention relates to a mold type jig manufacturing method for attaching a tube for orthodontic correction, a mold type jig and a method for attaching a tube for orthodontic correction (a mold type jig for a bonding orthodontic tube,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mold-making jig manufacturing method, a mold-type jig and a tube attaching method for orthodontic tube, and more particularly to an apparatus for attaching a tube for orthodontic correction to a desired tooth position, Shaped jig for attachment of a tube for orthodontic treatment, and a method of attaching a tube for orthodontic correction.

Teeth that are present in the human oral cavity may have an uneven tooth alignment due to congenital or acquired deformities. Malocclusion refers to malocclusion, which causes functional problems such as an aesthetic problem that adversely affects appearance in human life, and a linguistic use of food intake or inaccurate pronunciation . Accordingly, orthodontic appliances have been used as dental treatment means for correcting malocclusion of teeth.

And a lingual correction method of correcting the teeth by attaching an orthodontic appliance to the surface of the tooth facing the inside of the oral cavity. In recent years, There is a high preference for lingual correction methods in which the orthodontic appliance is not exposed to the outside.

Conventional conventional orthodontic appliances used in orthodontics consist of a bracket attached to the patient's teeth and a line connecting the tooth formed in the bracket to provide a traction force to move the teeth to the calibration position. At this time, the bracket is formed with a base to be attached to the tooth surface.

Conventional orthodontic braces attach brackets one by one to the surface (tooth surface) of each dental tooth making a dentition and ligate an arch wire of rigid material to the slots formed in each bracket by ligation wire, Direction was gradually corrected over a long period of time.

However, in conventional orthodontic braces, when the wire is ligated to the slot of the bracket, the gap between the tooth surface and the wire is formed at a relatively large interval in order to secure a treatment space.

In addition, a ligation wing was formed on the bracket to fix the line to the ligation line.

The bracket profile of the bracket is increased and the volume of the bracket is inevitably increased in order to secure the gap between the tooth surface and the base, the thickness of the base, and the ligation wing structure,

In addition, the undercut structure necessarily formed between the bracket and the ligation wing causes a problem that the residues of the food remain in the oral cavity, thereby deteriorating oral hygiene.

In particular, the increase in the distance between the tooth surface and the line leads to poor control of the tooth position. The orthodontic force exerted on the tooth is applied to the bracket, not the center of gravity or resistance center of the tooth. As such, the orthodontic force that does not pass through the center of resistance of the tooth inevitably generates a rotational moment. As a result of this moment of rotation, the teeth bound to the line are rotated around the bracket slot as the center of rotation. 1, there is a problem in a case where a rotation moment is generated unintentionally due to another tooth movement or a problem of a tilting of the teeth T is caused by a torque bend, a torque twist the third order bend is applied to the bracket 201 so that the rotation moment M is applied to the bracket 201. The rotation of the tooth T takes place with the arc 203 inserted in the slot of the bracket 201 as the center of rotation, As a result, the vertical height of the tip of the tooth (cut edge, tibia) as well as the slope of the lingual side of the tooth changes. The farther away the bracket slot from the tooth surface (the larger the bracket 201 profile), the greater the problem.

On the other hand, orthodontic tubes, which are minitubes, are widely used for orthodontic brackets. These orthodontic tubes are divided into two types, one is a base and the other is a tube itself.

In the case of a tube without a base, the resin is applied to the outside and attached to the teeth, and then an orthodontic line is inserted to perform orthodontic correction.

At this time, it is very difficult for skilled physicians to attach the orthodontic tube to the correct position on the tooth and to apply the resin with sufficient bonding force in an appropriate amount.

Hereinafter, a method of manufacturing a mold-type jig according to the present invention will be described in detail with reference to FIG.

In the mold-type jig manufacturing method of the present invention, the pre-correction dentition model of the patient is acquired (S100).

In addition, the pre-orthodontic dental model 10 may be a dentition model of a patient's dentition before orthodontic treatment, for example, a dentition model of a malocclusion state in which the lateral incisors are lingually displaced as shown in Fig.

In addition, the pre-correction dentition model 10 may be a digital model on a computer program obtained through dental photography such as CT or panorama.

However, the pre-correction dentition model 10 may be a dentition model of an actual patient prepared through an impression process.

Next, the teeth of the pre-orthodontic dental model 10 are arranged in the tooth arrangement after the desired orthodontic treatment to generate a dental model after the correction (S200).

Fig. 4 shows the posterior dentition model 20, which is an ideal dentition model in which the lateral incisor malocclusion is solved.

However, the generation process of the dental model after the correction (S200) may be omitted, and in this case, the tube resin joint model 40 described below is directly attached to each tooth of the pre-dentition model 10 .

Next, as shown in FIG. 5, the orthodontic arc model 30 is positioned as close as possible to the posterior orthodontic model 20, and the tube resin joint model is calibrated along the orthodontic arc model 30, And placed on each tooth of the dental model 20 (S300).

However, the placement process of the orthodontic arc model 30 may be omitted, and only the tube resin joint model 40 may be attached to each tooth of the posterior dental model 20 after the correction.

6, the tube resin joint model 40 includes a tube model 41 and a resin model 42, which is wrapped around the tube model 41 and is applied to the orthodontic arc model 30, ) Is a combined model.

In addition, the size of the resin models 42 may vary according to the distance between the teeth of the posterior dental model 20 and the orthodontic arc model 30.

Next, the posterior dentition model 21 attached with the tube resin joint model 40 is restored to the dentition shape of the pre-orthodontic dentition model 10 (S400).

However, this step may be omitted if the tube resin composite model 40 is attached directly to the pre-calibrated dental model 10.

In addition, when restoring the teeth of the pre-orthodontic dental model 10, the orthodontic arc model between the tube resin joined body models 40 is cut.

In detail, the calibration line segments 31 between the tube resin composite body models 40 are cut out and removed while leaving a predetermined length to be exposed to both sides of the tube model 41.

This is to prevent penetration of the resin into the orthodontic tube, which is the actual tube corresponding to the tube model 41 when filling the resin in the mold-type jig.

That is, the orthodontic tube 72 in which the wire piece 71 is inserted is prepared by inserting the wire piece 71 into the orthodontic tube 72 to be actually attached to the patient.

In addition, the orthodontic tube 70 has a slope (a) so that both ends thereof are beveled. This facilitates the insertion of an orthodontic wire.

However, this step may be omitted in the case where an orthodontic tube mounting groove for directly mounting the orthodontic tube 70 is formed inside the mold-type jig 100.

Next, as shown in FIG. 13, the orthodontic tube 72 with the wire piece inserted therein is inserted and fixed in the wire piece engaging groove 110 of the mold-type jig 100 (S2000).

The orthodontic tube 70 is seated on the resin filling groove 120 of the mold jig 100 so that the orthodontic piece 71 is placed so as to extend over the arc piece mounting groove 110 of the mold jig 100, So as to be fixed in a floating state.

14, the resin filling groove 120 is filled with the resin 81, the outer circumference of the orthodontic tube 70 is wrapped around the resin filling groove 120, (S3000).

Next, as shown in Fig. 15, the mold-type jig 100a to which the resin is applied is inserted into the patient's teeth 11 (S4000), and the polymerization is performed so that the orthodontic tube 70 is inserted into each tooth of the patient (S5000).

Further, the polymerization may be a photopolymerization which cures the resin 81 by irradiating light.

Then, the orthodontic tube 70 is attached to the patient's teeth by the resin 81 (S6000).

Next, the mold-type jig 100 is separated from the patient's teeth and removed (S7000).

Then, as shown in Fig. 16, only the orthodontic tube 70 attached by the resin 81 is present in the patient's teeth.

Next, the wire piece 71 inserted into the orthodontic tube 70 is removed to complete the attachment of the orthodontic tube 70 (S8000).
