Specification

Orthodontic set and mounting method of orthodontic bracket

Technical field

[0001] The present invention relates to an orthodontic set used for simply and accurately performing an operation of adhering and fixing an orthodontic bracket for correcting tooth alignment to a lingual surface of a tooth, and a dental using the orthodontic set The present invention relates to a mounting method of a correction bracket.

Background art

[0002] Normally, orthodontic treatment of teeth is performed by attaching orthodontic brackets of orthodontic appliances outside the teeth and then ligating wires to each orthodontic bracket. In this treatment method, a method (direct method, direct bonding) in which the orthodontic bracket is directly bonded and fixed to the labial surface of the patient's teeth is adopted. However, in this method, orthodontic brackets and wires are attached to the outside of the teeth, so that the orthodontic device can be seen by humans. Therefore, a lingual orthodontic method that treats from the back side of the tooth has been devised and has become popular in recent years.

[0003] In lingual correction, the shape of the back side of the teeth is more complex than the outside, and even if the orthodontic bracket is slightly misaligned, the movement of the teeth can vary greatly, resulting in a good therapeutic effect. There is a problem that can not be. Therefore, in lingual orthodontic treatment, the dental technician adjusts the mounting position of the orthodontic bracket on the patient's model in advance and adjusts it so that it can be accurately attached to the patient's teeth. The method of attaching the bracket for correction (indirect method, indirect bonding) is adopted.

[0004] With this indirect method, corrective devices can be accurately attached to each patient, so that a good treatment result can be obtained. Impression collection (dental shaping), model production, technical operation, etc., takes time and cost. Is a drawback. The present applicant has proposed a method in Japanese Patent No. 3118213 that improves the indirect method, and can more accurately attach the correction device, and can simplify both the force and the technical operation compared to the conventional method.

[0005] However, the indirect method is indispensable for impression collection, model production, technical operation, and the like, and has a drawback that it takes time and cost compared to the direct method. Also, the engineer There are also disadvantages in that the treatment results depend on the quality of the setup model, the condition of the setup model, the manufacturing condition of the orthodontic bracket, etc.

[0006] In order to adopt the direct method instead of the indirect method having such drawbacks, the orthodontic bracket is simply and accurately placed on the back side of the tooth (the lingual surface). ) Must be able to be worn.

[0007] Therefore, the applicant of the present invention disclosed in Japanese Patent Laid-Open No. 2000-14681 has an orthodontic bracket capable of easily and accurately positioning an orthodontic bracket that is an obstacle to adopting the direct method. Propose a fixture.

Disclosure of the invention

[0008] An object of the present invention is to provide an orthodontic set which can position an orthodontic bracket more simply and accurately by improving the orthodontic bracket fitting disclosed in the above-mentioned published patent publication. The purpose is to propose a method of mounting the orthodontic bracket.

[0009] In order to achieve the above object, the present invention provides an orthodontic set used for positioning and fixing an orthodontic bracket on a lingual surface of a tooth,

A plurality of bracket fixtures and a plurality of orthodontic brackets, each bracket fixture comprising an indicator temporarily bonded to the labial surface of the tooth, and a connection member having a substantially U-shape; The indicator is attached to one end of the connecting member, and an attachment portion for attaching the orthodontic bracket in a removable state is formed on the other end of the connecting member,

As the bracket mounting tool, ones having different relative positional relations between the indicator and the orthodontic bracket mounted on the mounting portion of the connecting member are prepared! /

[0010] Here, as the bracket attachment tool, ones having different height positions of the orthodontic bracket attached to the connecting member in a state where the indicator is attached to the lip side surface of a tooth are prepared. Can do.

[0011] Further, as the bracket attachment tool, ones having different torques of the orthodontic bracket attached to the connecting member in a state where the indicator is attached to the lip side surface of a tooth can be prepared. [0012] Further, as the bracket attachment tool, it is possible to prepare ones having different orthodontic brackets attached to the connecting member in a state where the indicator is attached to the lip side surface of the tooth.

[0013] Further, as the bracket attachment tool, there may be prepared different in-out brackets for the orthodontic bracket attached to the connecting member in a state where the indicator is attached to the lip side surface of the tooth. it can.

[0014] In addition to this, as the bracket fixture, there are prepared different orthodontic bracket rotations attached to the connecting member in a state where the indicator is attached to the lip side surface of the teeth. I can keep it.

[0015] In the operation of attaching the orthodontic bracket to the lingual surface of the patient's teeth using the bracket fixture, first, the orthodontic bracket is attached to the connecting bar of the bracket fixture. Next, the bracket mounting tool is put on the teeth so that the connecting bar straddles the teeth. As a result, the orthodontic bracket faces the back of the tooth (the lingual surface) and the indicator faces the front of the tooth (the labial surface). Next, the indicator located on the front side is positioned on the lip side surface of the tooth and temporarily fixed with an adhesive. When the indicator is temporarily fixed, the orthodontic bracket on the back side of the teeth that are connected via the connecting bar is also positioned. Next, an adhesive is filled in the gap between the orthodontic bracket and the lingual surface of the tooth. When the adhesive hardens, the orthodontic bracket is in place on the lingual surface of the tooth. Finally, remove the bracket attachment from the orthodontic bracket as well as remove the tooth force. That is, remove the indicator temporarily fixed on the tooth surface and remove the connecting bar from the orthodontic bracket. The adhesive filled between the orthodontic bracket and the lingual surface of the tooth may be applied in advance to the surface of the orthodontic bracket.

[0016] Various bracket attachments are prepared in the orthodontic set of the present invention. Therefore, it is possible to attach the orthodontic bracket to the optimum position in the optimum state by using the optimum bracket fitting for each tooth.

[0017] For example, the thickness of the teeth may be different even for the same patient's left and right teeth of the same patient. In such a case, use a different bracket in / out, ie, a bracket fixture with a wide connecting bar and a narrow bracket fixture with a connecting bar. [0018] Also, due to the difference in tooth length (clinical crown length) and the progress of treatment, the mounting position of the orthodontic bracket is closer to the incision (shallow position) than the adjacent teeth or the same-named teeth. Or you may have to change it closer to the gingiva (deeper). It may also be necessary to adjust for proper tooth inclination and torque. Usually, these adjustments are made by bending the wire. In the present invention, various bracket fittings are prepared, for example, those in which the positional relationship between the orthodontic bracket and the indicator is different. Therefore, the position of the orthodontic bracket can be changed by selecting the optimal bracket fitting, so there is no need to bend the wire.

[0019] Further, the orthodontic set of the present invention can be used in common for the upper and lower 12 front teeth.

[0020] Next, the present invention is a method for mounting an orthodontic bracket using the orthodontic set having the above-described configuration,

From the orthodontic set, select a bracket fixture that is appropriate for each tooth of the patient, and use the bracket fixture to attach an orthodontic bracket to each tooth. Record or store the correspondence with the bracket fixture used to attach the bracket,

When changing the position of the orthodontic bracket with respect to each tooth, a bracket fixture that can set the orthodontic bracket at the target position on the lingual tooth surface is included in the orthodontic set based on the above relationship. Select from

The orthodontic bracket is attached to each tooth using the selected bracket fixture, and when the orthodontic bracket is attached to each tooth, the mounting position of the indicator is set to a fixed position. RU

[0021] Here, in the method of the present invention, as the correspondence, at least two of the height, the angiulation, torque, in-out, and rotation are recorded or stored, and the orthodontic for each tooth is recorded. When changing the position of the dental bracket, the bracket fixture capable of setting the orthodontic bracket to the target site is selected based on these values.

[0022] For example, when attaching an orthodontic bracket to a patient's teeth, a prepared correspondence is prepared. Enter the data in the table. Specifically, which bracket attachment was used for which tooth, in other words, how many millimeters in depth, how many torques, how many angiulations, how many millimeters, Record whether you used the bracket fixture

[0023] In this way, for example, when the height of the upper right thread trimming tooth is 2 mm lower, the orthodontic bracket currently attached to the tooth is attached in what state and in what position. From the correspondence table, a new orthodontic bracket can be attached to the target position using a bracket fitting that is set 2mm deep. Brief Description of Drawings

BEST MODE FOR CARRYING OUT THE INVENTION

[0025] Hereinafter, an orthodontic set and an orthodontic bracket mounting method to which the present invention is applied will be described with reference to the drawings.

FIG. 1 is an explanatory view showing a state in which an orthodontic bracket is mounted on the lingual surface of a tooth using a bracket fixture included in the orthodontic set of this example. FIG. 2 is an explanatory view showing the labial surface of the tooth, and FIG. 3 is an explanatory view showing the lingual surface of the tooth. The orthodontic set 100 of this example has a plurality of types of bracket fixtures 1 and a plurality of types of orthodontic brackets 5. [0027] The bracket fixture 1 includes an indicator 3 temporarily bonded to the lip side surface 21 of the tooth 2 and a connecting bar 4 (connecting member) attached to one end of the indicator 3 in a detachable state. I have. The orthodontic bracket 5 is attached to the other end of the connecting bar 4 in a detachable state.

[0028] The connection bar 4 is generally U-shaped as a whole, and includes a connection portion 41 having a predetermined length, a labial arm portion 42 extending in parallel in a direction perpendicular to both ends of the connection portion 41, and And a lingual arm portion 43. The tip of each arm portion 42, 43 is bent at a right angle inside, forming an indicator mounting portion 44 and a bracket mounting portion 45, respectively.

[0029] The indicator 3 is a plate-like member having a surface portion 31 temporarily fixed to the lip side surface 21 of the tooth 2 and a back surface portion 32. The back surface portion 32 has an indicator mounting portion of the connecting bar 4 A fitting groove 33 is formed in which 44 is detachable. An index 34 used for positioning is printed or engraved on the surface of the back surface portion 32. The indicator 3 having this configuration may have a shape similar to that of the orthodontic bracket, or may have a different shape, for example, a shape similar to a crown outer shape.

[0030] The orthodontic bracket 5 has the same structure as that generally used, and a base 51 that is bonded and fixed to the lingual surface (back side) 22 of the tooth 2 via an adhesive 6. , And a mounting portion 52 used for laying a wire attached to the back surface of the base 51. The attachment portion 52 is formed with a slot 53 for receiving a wire used for treatment. In this example, the slot 53 is used as a fitting groove for fitting the bracket mounting portion 45 of the connecting bar 4 in a detachable state. Of course, it is also possible to form a fitting groove for attaching the connecting bar separately from the slot 53.

[0031] Here, the indicator 3 is set at a fixed position on the labial surface 21 of the tooth 2 to be corrected, and the position of the orthodontic bracket 5 relative to the indicator 3 set on the tooth 2 is Adjusted by element.

(1) Bracket height

(2) Bracket anguilleration

(3) Bracket torque (4) Bracket in / out

(5) Bracket rotation

Bracket height (hereinafter simply referred to as height) is the distance to the bracket slot in terms of tooth incision and cusp apex force. It depends on the size.

[0032] Bracket anguilla- tion (hereinafter simply referred to as anguilla- tion) is an inclination angle with respect to the long axis of the tooth when viewed from the front, and the lingual arm of the connecting bar 4 This is determined by the near-centrifugal inclination angle of the orthodontic bracket 5 with respect to the portion 43 (see Fig. 9 below).

[0033] Bracket torque (hereinafter simply referred to as torque) is an angle of inclination with respect to the long axis of the tooth when the side force is also viewed, and dental correction with respect to the lingual arm portion 43 of the connecting bar 4 It depends on the mounting angle of the bracket 5 (see Figures 6 and 7 below).

The bracket in / out (hereinafter simply referred to as “in / out”) is an attachment position in the tooth thickness direction, and is determined by the length of the connecting portion 41 of the connecting bar 4.

[0035] Bracket rotation (hereinafter simply referred to as rotation) is a rotation centered on the long axis of the tooth, and depends on the orientation of the orthodontic bracket attached to the lingual arm portion 43 of the connecting bar 4. (See Figure 10 below).

[0036] In the orthodontic set 100, bracket attachments 1 having different values for each element are prepared so that each element (1) to (5) can be adjusted. As an example, if three different values are prepared for each element as shown below, 243 nominations will be obtained. Of course, a smaller number or a larger number of variations may be used.

(1) Noise 3mm Omm + dmm

(2) Anguilleon + 2 ° 0 °-2 °

(3) Torque 5 ° 0 ° + 5 °

(4) In-out 8mm 5mm 3mm

(5) Rotation + 2 ° 0 °-2 °

These medium powers will be selected and used. The task of selecting many types of medium and optimal is difficult, so data such as the types that are frequently used are collected. It is possible to save labor in selecting work by collecting data.

[0037] It is assumed that the indicator 3 is always attached at a certain position on the labial surface 21 of the tooth 2. Therefore, the connection state of the indicator 3 and the connection bar 4 is the same. Of course, since there are differences in the form of teeth, it is possible to prepare a bracket fixture 1 in which the connection state of the indicator 3 is different.

Next, an example of the bracket attachment 1 included in the orthodontic set 100 of this example will be described with reference to FIGS. 4 to 9.

[0039] In the bracket fitting la shown in Fig. 4, the orthodontic bracket 5 is attached as compared to the length L (42a) of the labial arm portion 42a to which the indicator 3 in the connecting bar 4a is attached. The length L (43a) of the lingual arm portion 43a is longer. Further, the length L (41a) of the connecting portion 41a that connects the both arm portions 42a and 43a is longer than the other arm bracket portions 42a and 43a. When the indicator 3 of the bracket fixture la is positioned at a fixed position on the labial surface 21 of the tooth 2, the orthodontic bracket 5 is positioned closer to the gingiva (deep position) of the lingual surface 22.

[0040] In the bracket fixture lb shown in FIG. 5, the labial arm portion 42b of the connecting bar 4b is longer than the lingual arm portion 43b. In addition, the distance between the two arm portions 42b and 43b, which is shorter than the other bracket fittings, is shorter. When the indicator 3 of the bracket fixture lb is positioned at a fixed position on the labial surface 21 of the tooth 2, the orthodontic bracket 5 is positioned closer to the incision (shallow position) of the lingual surface 22.

[0041] In the bracket fixture lc shown in FIG. 6, the lengths of the labial arm portion 42c and the lingual arm portion 43c of the connecting bar 4c are substantially equal. The length of the connecting portion 41c (interval between both arm portions) is set to an intermediate dimension between the connecting portions 41a and 41b of the bracket fittings la and lb in FIGS. Further, the bracket mounting portion 45c formed at the tip of the lingual arm portion 43c is bent at an obtuse angle on the lip side. The orthodontic bracket 5 attached here is inclined to the lip side rather than facing downward, and can be attached to the portion of the torque T of the tooth 2 (the inclination angle when the side force of the tooth 2 is viewed). Become. When the indicator 3 of the bracket fixture lc is positioned on the labial surface 21 of the tooth 2, the orthodontic bracket 5 is positioned in the middle of the lingual surface 22. The orthodontic bracket 5 is inclined to correspond to the torque T of the tooth 2 Therefore, it will be in the state positioned by an ideal angle.

[0042] In the bracket fixture Id shown in FIG. 7, the connecting bar 4d has the labial arm portion 42d longer than the lingual arm portion 43d, like the connecting bar 4b in FIG. In addition, the distance between both arm portions 42d and 43d, where the length of the connecting portion 41d is short, is narrowed. The bracket mounting portion 45d of the connecting bar 4d is bent inward at an acute angle, and the orthodontic bracket 5 attached thereto is directed to the lip side at a predetermined inclination angle. When the indicator 3 of the bracket fixture Id is positioned at a fixed position on the labial surface 21 of the tooth 2, the orthodontic bracket 5 is positioned near the incision edge of the lingual surface 22 of the tooth 2. Since the orthodontic bracket 5 has an inclined posture corresponding to the torque T of the tooth 2, a state of being positioned at an ideal angle is formed.

[0043] The bracket attachment le shown in FIG. 8 is an attachment angle suitable for attachment to a tooth having an anguilla- tion A (inclination angle with respect to the long axis of the tooth 2 when the tooth 2 is viewed from the front). The bracket 5 for correction can be attached. The elements other than the angiulation can be the same as those shown in FIGS.

[0044] The bracket fixture If shown in Fig. 9 can attach the orthodontic bracket 5 with the teeth mesial or distally inclined to attach to the teeth 2 with angiulation. is there. The elements other than the angiulation can be the same as those shown in FIGS.

FIG. 10 is an explanatory view of the bracket mounting tool attached to the tooth 2 when viewed along the upper axis force of the tooth 2 along the long axis direction. The bracket fixture lg shown in Fig. 10 (a) is for a rotation force ^s O °, and the bracket fixture lh shown in Fig. 10 (b) is for a rotation at a predetermined angle toward the mesial or distal side. Is the case. Elements other than rotation can be the same as those shown in FIGS.

Next, a procedure for positioning and fixing the orthodontic bracket 5 on the lingual surface 22 of the patient's tooth 2 using the bracket fixture 1 will be described. First, the optimal bracket fixture 1 and orthodontic bracket 5 are selected from the orthodontic set 100 according to the thickness, size, shape, treatment content, etc. of the patient's teeth 2. For example, an optimal one is selected from the bracket fixtures 1 a to lh shown in FIGS. The orthodontic bracket is attached to the selected bracket fixture 1. Attach G5.

[0047] Thereafter, the bracket fixture 1 is placed on the tooth 2 so that the connecting bar 4 straddles the patient's tooth 2, and the lingual surface 22 of the tooth 2 and the orthodontic bracket 5 face each other. Thus, the indicator 3 is formed on the lip side surface 21 of the tooth 2 so as to face each other. Next, the indicator 3 located on the front side is positioned on the lip side surface 21 of the tooth 2 and temporarily fixed with an adhesive. At this time, the positioning operation can be performed with reference to the index 33 formed on the back portion 32 of the indicator 3. When the indicator 3 is temporarily fixed, the orthodontic bracket 5 on the back side of the tooth 2 connected via the connecting bar 4 is also positioned on the lingual surface 22 at the same time.

[0048] After that, the adhesive 6 is filled in the gap between the orthodontic bracket 5 and the lingual surface 22 of the tooth 2 and waits for the adhesive 6 to harden. When the adhesive 6 is hardened, the orthodontic bracket 5 is fixed to a predetermined position on the lingual surface 22 of the tooth 2. Finally, remove bracket fitting 1 from tooth 2. That is, the indicator 3 temporarily fixed to the surface 21 of the tooth 2 is removed, and the connecting bar 4 is removed from the orthodontic bracket 5.

Here, the adhesive 6 may be applied to the surface of the base 51 of the orthodontic bracket 5 before attaching the bracket 1 to the teeth 2!

[0050] In the above procedure, when the orthodontic bracket 5 is attached to the patient, an optimal combination of the pads is selected and assembled. Instead of this, it is possible to prepare a large number of types in which the parts are combined in advance, and select the optimal one from among them and attach it to each patient's teeth. In addition, it is possible to prepare a number of types of bracket attachments having a structure in which each part is manufactured as one piece for each size and each shape, and attach the optimum one.

[0051] Further, a patient's oral model may be manufactured in advance, and an optimal bracket fitting may be selected on the model in advance.

[0052] As described above, when the bracket fixture 1 of the present example is used, the positioning and fixing work of the orthodontic bracket 5 is easily performed in the same manner as when it is attached to the outer surface 21 of the tooth 2. be able to. As a result, there is no need to directly operate and position the orthodontic bracket 5 located on the back side of the tooth 2. Also, the dental after positioning Also in the operation of adhering and fixing the orthodontic bracket 5 to the back surface 22 of the tooth 2, the orthodontic bracket 5 is held in the positioning state because the indicator 3 is temporarily fixed to the surface 21 of the tooth 2. Therefore, it is not necessary to hold the orthodontic bracket 5 in that position until the adhesive 6 is cured.

Furthermore, in this example, since the indicator 3 and the connecting bar 4 are detachable, the work of removing the bracket fixture 1 after attaching the orthodontic bracket 5 to the tooth 2 becomes easy. It is also possible to repeatedly use the parts 3 and 4.

[0054] In contrast, in this example, a plurality of types of indicators 3 and connecting bars 4 are prepared, and the fitting grooves 33 of the indicators 3 and the indicator mounting portions 44 of the connecting bars 4 have the same dimensions. In addition, the bracket mounting portion 45 of each connecting bar 4 and the slot 53 of the dental correction bracket 5 have the same dimensions. Therefore, it is possible to assemble the bracket fixture 1 having the shape and size most suitable for the patient's teeth 2 and to attach the orthodontic bracket 5 most suitable for the patient's teeth 2 there.

Therefore, by using the bracket fixture 1 of the present example, the operation of positioning and fixing the orthodontic bracket 5 to the lingual surface 22 of the tooth 2 can be performed easily and accurately.

[0056] Here, when the orthodontic bracket 5 is attached to each tooth 2 of the patient using the bracket fixture 1, it is used to attach the orthodontic bracket 5 to each tooth 2 and each tooth 2. It is desirable to record or memorize the correspondence with the bracket bracket 1 that was used. When changing the position of the orthodontic bracket 5 with respect to each tooth 2, based on the corresponding relationship, the bracket fixture 1 that can set the orthodontic bracket 5 at the target position on the lingual tooth surface is orthodontic. Select from the set and attach the orthodontic bracket 5 to each tooth 2 using the selected bracket fixture 1. When the orthodontic bracket 5 is attached to each tooth 2, the attachment position of the indicator 3 is always positioned at a fixed position.

[0057] As the above correspondence, the above five elements (no, it, anguille, torque, in / out and rotation) are recorded or stored, and the position of the orthodontic bracket 5 for each tooth 2 is determined. When changing, based on these values, select bracket fixture 1 that can set orthodontic bracket 5 at the target site.

[0058] For example, when the orthodontic bracket 5 is attached to the patient's tooth 2, it is prepared in advance. Enter the data in the correspondence table. Specifically, which bracket fixture 1 was used for which tooth 2, in other words, how many millimeters in height, how many angiulations, how many torques, how many millimeters in and out, Record how many times the bracket attachment 1 was used for rotation.

In this way, for example, if the height of the upper right thread trimming tooth is 2 mm lower, it is possible to determine the state and position of the orthodontic bracket currently attached to the tooth. A new orthodontic bracket can be attached to the target position using a bracket fitting that is 2mm deep, read from the correspondence table.
