Description

[Correction 22.12.2016 by Rule 26] Transparent Calibration System

The present invention relates to a transparent calibration system, and more particularly, to a transparent calibration system that can be easily removable and used in various types of orthodontic and can reduce pain and improve orthodontic power.

In general, non-uniform dentition, malocclusion and facial protrusion are caused by the teeth and oral and maxillofacial regions not growing properly in place due to abnormal development of teeth or jawbone, bad habits or heredity affecting the teeth. Orthodontics and the structure of the oral cavity acts as a determinant of the impression of the person, and cause a decrease in the grinding function of food, so interest in orthodontics is increasing day by day.

Orthodontic treatment uses the property of a tooth to move under some force. The most widely used for orthodontic treatment is a fixed treatment method that attaches a bracket to a tooth and moves the tooth using elasticity such as orthodontic wires and rubber bands. Brackets are usually made of metal, with the disadvantage of being noticeable during treatment.

In order to solve this disadvantage, a transparent calibration method has been proposed. Transparent orthodontics is a procedure to make a transparent orthodontic appliance that changes step by step from the state of the tooth before the correction to the state of the tooth to be corrected, and to correct the orthodontics by changing it to the tooth.

Specifically, the procedure by the transparent orthodontic device was developed in 1997, is a dental orthodontic device developed by the US "Align Technology, Inc." under the name "Invisalign System", US Patent No. 5,975,893 And 6,217,325 and the like. The "Invisalign System" cuts teeth one by one on a computer using a special program for three-dimensional scan data of the teeth, and creates 20-30 pairs of models in stages to the position where the teeth should finally move through virtual simulation. It is to make a transparent plastic frame that can move teeth by model and distribute it to patients.

The "Invisalign System" is characterized by inserting a series of prepared plastic orthodontics into the teeth step by step, which gradually moves the teeth to be corrected to the final target point. Since it is not recognized, it can be a great help in the daily social life of orthodontic patients, and it can be said that the patient can attach or detach the orthodontic device as needed.

However, although the transparent calibration device has the advantages as described above compared to the fixed calibration device by the bracket described above, the situation is not much pain to the patient.

In other words, such transparent orthodontic treatment is to induce the tooth arrangement by using a hard sheet (硬質) due to the nature of the material to ensure the aesthetics, because of the rigid material properties of the transparent orthodontic device is hard, there is not much pain to the patient.

In addition, despite the many advantages of the transparent orthodontic device, what is worse than the stationary orthodontic device is that if the device does not fit well during tooth movement, the device is not well seated and the desired tooth movement is difficult. In particular, when the teeth are corrected using the transparent calibration device as shown in Figure 1, the phenomenon that the teeth are inclined unintentionally.

That is, as shown in (a) of FIG. 1, the distance between the first tooth T1 and the second tooth T2 is wide so that the teeth of the second tooth T2 are moved to the first tooth T1 side. When the transparent calibrator 10 is covered on the upper portion of the second tooth (T2) is applied to the force from the upper side to the first tooth (T1). In this case, the lower region and the root side of the second tooth T2 are not subjected to the force, and the corrective force is eccentrically applied only to the upper direction of the second tooth T2, so that the second tooth as shown in FIG. The phenomenon that T2 is moved inclinedly occurs.

If the teeth are inclined continuously, the teeth may lie down or, in severe cases, hit the adjacent tooth roots to cause root absorption, and the first transparent calibrator will not fit, resulting in the hassle and cost of remanufacturing. And an increase in the duration of orthodontic treatment.

In addition, the conventional transparent calibrator must find the boundary between the transparent calibrator and the gum with the nail when the transparent brace is removed from the teeth, and it is not easy to remove the pierced gums with the fingers, pain can occur, and the nail If the braces are stabbed under the nail, the pain can be severe and irritate the gums.

On the other hand, when the tooth is rotated using a conventional transparent brace, or straightened, pushed down and the tooth straight up, an additional attachment that can improve each of the corrective effect on the transparent calibrator is used to attach to the tooth surface.

In this case, the attachment is messy to look at, but if you have two corrective actions on the tooth, for example, rotation and pressing together, or if you are correcting the rotation and alignment together, several attachments must be attached to one tooth. As described above, in the state where a plurality of attachments are attached to the teeth, it is more difficult to detach the transparent calibrator. In addition, it is easy to cause deformation when detached to the tooth, it is easy to drop the attachment.

However, when only a part of the plurality of attachments attached to the tooth falls, both the patient and the doctor are difficult to recognize.

An object of the present invention is to solve the above problems, to provide a transparent calibration system that can perform various types of orthodontic, such as rotation, pressing, inclination, using a tooth-corrected orthodontic correction device of one shape will be.

Another object of the present invention is to provide a transparent calibration system capable of horizontal movement of the tooth rather than the tilt movement of the tooth.

Still another object of the present invention is to provide a transparent calibration system that is easily removable on a tooth.

Still another object of the present invention is to provide a transparent calibration system that enables the patient and the doctor to easily recognize whether or not the orthodontic attachment is removed.

Still another object of the present invention is to provide a transparent correction system that can maintain a weak pressure to induce direct absorption of bone, reduce pain, and provide rapid orthodontic effects.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiment of the present invention may be modified in various forms, the scope of the invention should not be construed as limited to the embodiments described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shape of the elements in the drawings and the like may be exaggerated to emphasize a more clear description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.

2 is a perspective view showing the configuration of a transparent calibration system 100 according to the present invention. As shown, the transparent calibration system 100 according to the present invention is a dental attachment orthodontic 110 attached to the teeth (T), transparent teeth braces 120 to cover the teeth (T) to correct the teeth (T) It includes.

The dental attachment 110 is attached to the surface of the tooth to be corrected to add the corrective effect of the teeth with the transparent teeth braces 120. In particular, the orthodontic appliance 110 according to the present invention can be used for all kinds of orthodontics, such as rotation, pressing, inclination of the tooth in one shape.

3 is a perspective view showing the configuration of the orthodontic appliance 110 of the present invention. As shown in the drawing, the dental attachment 110 is formed by integrally combining a vertical axis 111 disposed perpendicular to the tooth and a horizontal axis 113 disposed horizontally on the vertical axis 111 in a "+" shape. The dental attachment 110 may be formed of resin or synthetic resin, metal, ceramics, or the like of tooth colors and various colors that are not exposed to the outside even when attached to the teeth.

Here, the angle between the vertical axis 111 and the horizontal axis 113 may be formed at an angle other than the right angle in some cases. That is, it may be formed larger than 90 ° or smaller than 90 °.

The dental attachment 110 is formed to correspond to the shape of the tooth surface is in contact with the teeth, the upper surface (111a, 113a) is formed in a gentle curved surface to facilitate the insertion and separation of the transparent braces 120 do. The

vertical surfaces

111b and 113b connecting the engaging surface and the upper surface are disposed at 90 ° or more or less than 90 ° on the tooth surface.

In some cases, only

upper ends

111a and 113a may be formed in a curved shape, and the remaining portions except for both ends may be formed in a flat shape.

The

vertical surfaces

111b and 113b are accommodated in the corrective accommodation pocket 123 when the transparent teeth straightener 120 is fitted to the teeth and supported by the corrective accommodation pocket 123. As a result, the transparent braces 120 apply a force in the direction in which the teeth are to be corrected.

The vertical surface 111b of the vertical axis 111 is coupled to the transparent teeth braces 120 and applies orthodontic force during tooth movement, tilt movement and rotation of the teeth. The vertical surface 113b of the horizontal axis 113 applies a corrective force at the time of the tooth reduction and the extraction slope. In addition, the

vertical planes

111b and 113b of the horizontal axis 113 and the vertical axis 111 may be used together.

Here, when the teeth are to be corrected, the orthodontic appliance 110 of the present invention is attached according to the state of the teeth before the correction. That is, when the teeth are corrected, the orthodontic appliance 110 has the vertical axis 111 and the horizontal axis 113 located in the vertical direction and the horizontal direction with respect to the tooth surface. When the dental attachments 110 are attached to the plurality of teeth, when all of the teeth are corrected, the horizontal axes 113 of the plurality of dental attachments 110 are all arranged side by side and the vertical axes 111 are parallel to each other. It must be deployed.

Here, the vertical axis 111 and the horizontal axis 113 may not be positioned side by side even after the completion of the correction depending on the type of correction of the teeth.

When the tooth is to be moved, the tooth attachment correction 110 is attached to the central axis of the inclined tooth, when the tooth is to be rotated, the tooth attachment correction 110 is attached to one side of the deflected tooth.

Therefore, the doctor may determine the progress of the correction of the teeth by looking at the current state of the dental attachment 110 attached to the tooth.

Here, the length and height of the vertical axis 111, the length and height of the horizontal axis 113 may be adjusted differently according to the type of calibration and the degree of calibration progress. That is, in the initial stage of correction, the height of the vertical axis 111 and the horizontal axis 113 is set low to alleviate the pain received by the patient. As a result, the pressing force applied to the tooth together with the transparent braces 120 may be relatively reduced, and pain of the patient may be alleviated. As the calibration proceeds, the length and height of the horizontal axis 113 and the vertical axis 111 may be gradually increased.

As the length and height of the horizontal axis 113 and the vertical axis 111 increase, the area of the

vertical surfaces

111b and 113b contacting the transparent teeth braces 120 increases, so that the corrective force applied to the teeth increases.

4 is an exemplary diagram illustrating various embodiments of the dental attachment 110. Orthodontic attachment 110 may be provided in various forms according to the type of correction to be performed on the teeth. Figure 4 (a) is the shape of the dental attachment 110 is the most basic. The vertical axis 111 and the horizontal axis 113 are arranged to cross each other. FIG. 4B illustrates a dental attachment 110 'having only a vertical axis 111, and FIG. 4C illustrates a dental attachment 110' having only a horizontal axis 113. Referring to FIG.

4 (d) is the upper surface is a toothed orthodontic member 110 '' 'coupled to the correction force relaxation member 115 in order to shorten the length of the vertical surface when the correction force does not need to be applied. Orthodontic relaxation member 115 may be attached to the dental attachment orthodontics 110 "'with a smooth upper surface, or may be attached to the dental model for forming the transparent braces 120.

Orthodontic relaxation member 115 is coupled between the vertical axis 111 and the horizontal axis 113 on the tooth model for manufacturing the transparent teeth braces 120 so that the corrective accommodation bag 123 is molded in a relaxed shape. Orthodontic force relaxation member 115 may be adjusted in size and shape differently according to the type of calibration and the type of orthodontic teeth, the use can be determined.

(E) and (f) of FIG. 4 are without any one of four types of the vertical axis 111 and the horizontal axis 113. The shape of the tooth attachment 110 may be provided in various ways in addition to the examples shown.

On the other hand, when a large orthodontic force is required for the correction of the teeth, as shown in Figure 2 may be disposed a plurality of orthodontic attachment 110 on the cheek side and the tongue side of the tooth.

The transparent braces 120 are inserted into the teeth and apply the corrective force in the direction in which the teeth are to be corrected. The transparent braces 120 are formed so that the tooth insertion grooves 122 inserted into the teeth correspond to the teeth form of the teeth. At this time, the transparent braces 120 do not need to excessive movement at once, and is formed to apply pressure with a weak force to the periodontal ligament of the tooth to be moved in a state well formed to fit the tooth. This induces direct bone resorption to speed up tooth movement.

Conventional ear line and ecliner can cause pain to the patient because they induce a large range of movement by 1 mm at a time. If strong pressure persists, indirect absorption causes the tooth movement to appear slowly in 7 to 14 days and accompany pain. In addition, since the correction width between the transparent tooth brace of the next stage and the transparent tooth brace of the previous stage is large, a longer time is required to fit the transparent tooth brace of the next stage to the teeth. Putting the next clear tooth straightener in place quickly will not fit well and the calibration will not work as desired. In this case, there may be a case where the impression is redrawn in the middle of the calibration and the transparent calibration apparatus is rebuilt.

On the other hand, the transparent braces 120 of the present invention by applying a weak pressure to induce direct absorption so that the tooth movement appears quickly in 1 to 2 days. At this time, the patient does not feel pain. In this manner, the transparent tooth braces 120 of the next stage are manufactured in a form well suited to the current dental condition so that the correction proceeds smoothly without pain.

Since the transparent tooth brace 120 of the present invention induces direct bone absorption to produce a faster correction effect, the average periodontal ligament space is 0.25mm ± 0.1mm, so 0.1mm, 0.2mm, 0.25mm, 0.3mm, etc. Each stage of transparent tooth brace is manufactured and provided to the patient with a small range of movement.

Since the transparent tooth brace 120 of the present invention proceeds with fine tooth movements, even if a new transparent tooth brace 120 is inserted into the tooth immediately after the correction, it is well suited to the teeth to elaborate several tooth movements at once. This can shorten the calibration period.

At this time, the tooth movement is induced little by little for three weeks, three times a week, and has a rest period for one week. In some cases, the replacement period may be less than a week or even more. If your tooth movements are small, you can go directly to another step without rest. If necessary for this pause, the transparent tooth straightener 120 of a more rigid material can be fitted to make sure that the calibration state is in between.

* The transparent teeth braces 120 of the present invention is formed to protrude on the buccal side of the transparent teeth correction base body 121, the transparent teeth correction base body 121 is formed with a tooth insertion hole (122) A corrective accommodation bag 123 to accommodate, and a removal protrusion 124 is formed to protrude on the molar side of the transparent teeth correction body 121 to facilitate detachment from the tooth.

Orthodontic accommodation bag 123 is formed to extend from the transparent tooth orthodontic base 121 to correspond to the orthodontic attachment 110 as shown in Figure 5 (a) is a dental attachment 110 therein To accept. The corrective accommodation bag 123 is in contact with the

vertical surfaces

111b and 113b of the vertical axis 111 and the horizontal axis 113 to apply the corrective force in the direction in which the teeth should be moved.

Here, the corrective accommodation bag 123 is formed to be larger than the orthodontic attachment 110 as shown in Figure 5 (b) in the initial orthodontic treatment. Then, as the calibration proceeds, it is gradually formed to fit the dental attachment 110 as shown in (c) of FIG.

If the corrective accommodation pocket 123 is looser than the dental attachment 110, the correction force applied to the dental attachment 110 is weak, so the pain of the patient is reduced. As the calibration proceeds, the corrective accommodation bag 123 may be gradually formed to fit the orthodontic appliance 110 to increase the corrective force.

The stripping protrusion 124 is formed to protrude on the buccal side (cheek direction) or lingual side (tongue direction) in the molar direction of the transparent teeth correction body 121 to facilitate the user to separate the transparent teeth straightener 120 from the teeth.

The stripping protrusion 124 is formed to protrude on the surface of the transparent teeth straightener 120 as shown in the enlarged cross-sectional view along the line A-A of FIG. At this time, the lower or one side of the stripping protrusion 124 may be formed with a finger insertion groove 124a is inserted into the user's finger. Accordingly, when the user wants to separate the transparent tooth brace 120 from the teeth, the user can easily separate by inserting a finger into the finger insertion groove 124a and lifting upwards.

In order to separate the transparent calibrator from the teeth by the stripping protrusion 124, the user may spend time searching for the interface between the transparent calibrator and the gum and stab the boundary area with the nail to solve the problem of damaging the gum.

The removal protrusions 124 may be formed in one to four upper, lower, left, and right sides of the dental arch to facilitate the detachable attachment of the transparent dental braces 120 to the user.

On the other hand, the stripping protrusion 124 may be provided to protrude a hook that can connect an elastic member (not shown) during calibration.

Figure 6 is an exemplary view showing a process of moving the tooth of the tooth (T) is fitted to the dental attachment 110 and the transparent braces 120 of the present invention. As shown in (a) of FIG. 6, the distance between the first tooth T1 and the second tooth T2 is far enough to move the second tooth T2 horizontally in the direction of the first tooth T1. In this case, the transparent teeth correcting body 121 applies a corrective force for moving in the direction of the first tooth (T1) from the upper surface of the second tooth (T2). At this time, the orthodontic attachment 110 attached to the surface of the tooth is accommodated in the corrective accommodation bag 123, the vertical surfaces (111b, 113b) is supported in contact with the corrective accommodation bag (123).

Here, as shown in the enlarged cross-sectional view taken along the line BB of FIG. 6 (a), the

vertical surfaces

111b and 113b are in the direction opposite to the direction in which the transparent tooth calibration base 121 applies the pressing force. ) Is prevented from tilting the second tooth (T) in the direction of the first tooth (T) as shown in FIG. That is, since the toothed orthodontic appliance 110 located in the center of the second tooth T in the direction opposite to the direction in which the transparent tooth brace 120 is to be moved from the upper portion of the second tooth T is applied to the overall repulsive force, FIG. 6. As shown in (b) of FIG. 2, the second tooth T does not move inclined but moves in the horizontal direction toward the first tooth T in the horizontal direction.

At this time, in some cases, as shown in Figure 8 using the orthodontic hook 130 can be placed close to the center of resistance of the teeth to prevent the inclined movement.

7 is an exemplary view showing a process of tilting the teeth (T) using the transparent calibration system 100 of the present invention. As shown in (a) of FIG. 7, the teeth T are disposed to be inclined at an angle with respect to the vertical axis, and are inclined to move to the vertical position.

At this time, the tooth attachment correction 110 is attached to the surface of the tooth (T) inclined by the inclination of the tooth (T). Then, the transparent braces 120 are fitted to the teeth (T). The transparent teeth braces 120 and the dental attachments 110 are applied to the orthodontic force so that the teeth (T) inclined movement together in close contact with each other and is vertically corrected as shown in (b) of FIG.

When the correction is completed, when the orthodontic attachment 110 is viewed from the front, the contact point between the vertical axis 111 and the horizontal axis 113 is located at the center of the tooth so that both the doctor and the patient can recognize that the correction is completed. do.

In the transparent calibration system 100 of the present invention, when the calibration is completed, the position of the dental attachment 110 is in the same state as in FIG. 7 (b), so that both the patient and the doctor can recognize whether the calibration is in progress. do.

On the other hand, Figure 8 is an exemplary view showing a modification of the transparent teeth braces 120a of the present invention. As described above with reference to FIG. 6, when the tooth movement of the tooth is induced, the transparent teeth brace 120a applies the corrective force from the top to the tooth, and the orthodontic appliance 110 applies the corrective force from the center region of the tooth to the tooth. Done. However, even when the corrective force is applied in the upper and middle in this way, the corrective force may not be applied to the lower region of the tooth.

Figure 8 is for such a case, it is possible to move the tooth by using the orthodontic hook 130 to extend the orthodontic force to the lower part of the tooth.

To this end, as shown in (a) of FIG. 8, the hook pocket 125 into which the correction hook 130 is inserted is formed to protrude from the surface of the transparent teeth straightener 120a. The hook pocket 125 may be provided in various forms in a range in which the insertion head 131 of the orthodontic hook 130 is inserted and the position thereof can be fixed.

The orthodontic hook 130 includes an insertion head 131 inserted into the hook pocket 125, a support shaft 133 extending from the insertion head 131 in the gingiva direction (gum), and a lower portion of the support shaft 133. Protruding to the elastic member 150 includes an elastic member engaging means 135 is engaged.

As shown in FIG. 8B, when the tooth movement of the tooth T is required, the insertion head 131 of the orthodontic hook 130 is inserted into the hook pocket 125 of the transparent teeth straightener 120a. One end of the elastic member 150 is fixed to the elastic member catching means 135. The other end of the elastic member 150 is fixed to a screw (not shown) or a button (not shown) coupled to a gum (not shown).

As a result, the transparent teeth braces (not shown) apply the corrective force in the direction to be corrected, in the middle, the toothed orthodontic member 110 applies the corrective force, and the lower side the correction hook 130 and the elastic member 150 Applying the orthodontic force can be the tooth (T) as a whole can move the tooth.

On the other hand, Figure 9 is an exemplary view showing a modification of the transparent teeth braces 120 that can help the rotational movement of the teeth.

In order to rotate the teeth, the tooth attachment correction 110 is attached to the tooth eccentrically. Correspondingly, as illustrated in FIG. 9A, the corrective accommodation bag 123 of the transparent teeth straightener 120 is also eccentrically formed on the tooth T.

Since the transparent tooth brace 120 is molded in a state where the tooth attachment orthodontic member 110 is attached to the tooth, both the position and the shape of the tooth attachment corrector 110 are reflected. In this state, the shape of the corrective accommodation bag 123 is corrected to fit the tooth attachment orthodontics 110 or leisurely to manufacture a transparent tooth straightener (120).

In the transparent tooth brace 120 shown in FIG. 9, an open window 126 for exposing the calibration button 140 to the outside of the transparent tooth brace body 121 is cut out in a predetermined area.

Correction button 140 is disposed on one side of the tooth (T) eccentrically, as shown in Figure 9 (b), by applying an elastic force in the direction in which the teeth (T) to be rotated by the elastic member (150a). Will be placed. Although not shown in the drawings, the elastic member 150a may be fixed to a button (not shown) or a connector (not shown) coupled to the gingival edge.

At this time, the open window 126 is not only a function of exposing the correction button 140 to the outside, but also in consideration of the distance to move the correction button 140 when the teeth (T) is gradually rotated in the direction to be corrected. It is formed by cutting into a large area to have a length l3.

On the other hand, Figure 10 is an exemplary view showing another modified example of the transparent braces 120. The open window 126 described above was formed by being cut open in the lower end of the transparent teeth correction base 121. On the other hand, the transparent tooth brace 120 of another modified example is provided with a closed window 127 extending downward in a form covering a part of the gum (S).

If the calibration force of the above-described calibration hook 130 is insufficient, the transparent teeth straightener 120 itself may be turned off. In this case, by using a connector or a rubber band in the closed window 127, it can be connected to a miniscrew or other device to prevent the position of the transparent teeth braces 120 to be distorted. The closed window 127 may be installed on the cheek side or the tongue side or both sides.

As described above, when manufacturing the transparent tooth brace 120, the shape of the corrective accommodation bag 123 may be suitably or easily adjusted according to the shape and the timing of correction of the dental attachment 110 described above. In addition, the hook pocket 125, the closed window 127 or the open window 126 may be formed according to the type of correction and the correction force.

In addition, in consideration of the age and gum state of the patient wearing the transparent calibration system 100 may be reflected in the manufacture of the transparent teeth braces 120.

For example, in a patient whose gums fall below the general standard gum height of an adult, a black triangle that may be exposed to the outside without the gums may occur between the teeth. In this state, however, when the transparent tooth brace 120 is molded, an undercut occurs in the black triangle portion, so that the insertion of the transparent tooth brace 120 is difficult and when the transparent tooth brace 120 is separated from the tooth T In addition, there may be a problem of separating from the gums.

Thus, when manufacturing the transparent teeth braces 120 of the present invention, the transparent teeth braces 120 are formed from the molding mold to the gums or teeth as much as the portion corresponding to the black triangle. In this case, the transparent tooth braces of the black triangle portion are formed to be spaced apart from each other by the narrowing, so that the teeth can be easily detached.

In addition, in the case of the growing child during the manufacture of the transparent calibration system 100, when forming the maxillary transparent teeth braces 120 may be formed so as to cover all the palate (palate side). In this case, it is possible to induce the expansion of the maxilla and act as an anchor for the maintenance of power and control of a specific site.

Similarly, the transparent braces 120 may extend beyond the lingual gingival of the mandible to serve as anchors for mandibular expansion and specific site control.

In addition, the height of the transparent orthodontic body 121 may also be adjusted to a shorter length than the height of the tooth.

As described above, the transparent calibration system according to the present invention includes a transparent teeth brace that is formed with a small range of movement distance so that the patient does not suffer from pain, and includes a tooth attachment calibration that is attached to the patient's teeth to improve orthodontic power. . This can induce direct bone resorption, thereby reducing the pain of the patient and improving the corrective power.

Embodiments of the transparent calibration system of the present invention described above are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Could be. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims. It is also to be understood that the present invention includes all modifications, equivalents, and substitutes within the spirit and scope of the invention as defined by the appended claims.

The present invention relates to a transparent calibration system, and can be applied to the dental industry, such as orthodontics.
