Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an auxiliary tool for orthodontic treatment.

[0002]

2. Description of the Related Art In dental care, correction is performed for treatment of malocclusion. In orthodontic treatment, a method is usually adopted in which a bracket is fixed to a tooth, a wire is mounted between the brackets, and the alignment of the teeth is gradually improved by the elastic force of the wire.

[0003] The wire mounted on the bracket is bent as necessary to form a loop or the like.
The wire is brazed with a hook or a correction bullet processed into a predetermined shape. Then, depending on the state of the tooth to be corrected, the elastic force of the loop formed on the wire, the elastic force of the correction bullet, or by interposing a spring or rubber between the hook and the tooth to be corrected, Orthodontic treatment is being performed.

[0004]

[0006] Orthodontic bullets, hooks, and the like cannot be attached to a wire while the wire is attached to a bracket fixed to a tooth. This is because it is not possible to braze a correction bullet or a hook to the wire in the patient's mouth. Therefore, conventionally, when additional orthodontic bullets and hooks are attached to a wire, the wire is temporarily removed from the bracket, the necessary orthodontic bullets and hooks are brazed, and the wire is again attached to the patient's teeth. I had to take steps to attach it to a fixed bracket.

However, there is a problem that the work of removing the wire attached to the bracket or attaching the wire to the bracket again takes time, makes the patient wait, and reduces the efficiency of treatment. In order to solve such a problem, a hook called a crimper hook has been proposed. Such a hook can be attached in the oral cavity to the wire attached to the bracket.

[0006] However, even if only the hook can be attached to the wire in the oral cavity, depending on the arrangement of the teeth to be corrected, another member such as a correction wire must be attached to the wire. The wire had to be removed from the bracket once. The present invention has been made under such a background, and in a clinical field of orthodontic treatment, a wire, a spring, and a loop member required for orthodontics are attached to a wire mounted in the oral cavity of a patient. An object of the present invention is to provide an orthodontic treatment aid attachable to a wire.

[0007]

According to the present invention, there is provided an attachment portion which can be attached to an orthodontic treatment base material attached in relation to a tooth, and an operating body partially fixed to the attachment portion. Having. The mounting portion can be mounted on the base material mounted in relation to the teeth. That is, the attachment portion can be attached to the base material that has been attached in advance in the patient's mouth.
Therefore, necessary auxiliary tools can be appropriately added in the oral cavity of the patient, and the treatment time can be reduced, and the treatment workability can be improved.

The working body is preferably a member having elasticity, and in particular, a wire bent into a predetermined shape. The wire as the acting body forms a correction bullet and a spring loop. The working body can also be a tubular body through which a wire can be inserted. When a cylindrical body is used, a wire can be inserted through the cylindrical body to add a wire or the like.

[0009] The base material may be a wire mounted on a bracket fixed to the teeth, and in this case, the attachment of the auxiliary tool may be a clamp that clamps the wire and is fixed to the wire. it can. According to such a configuration, a bending loop, a correction bullet, and the like can be easily attached later to the wire attached to the bracket in the oral cavity of the patient, so that the treatment workability is improved.

The clamp can be easily clamped and fixed to the wire by, for example, pressing with a nipper or a plier. The parent material can also be a bracket fixed to the teeth. In this case, the mounting portion of the auxiliary tool can be an engagement plate that is engaged with the bracket. With such a configuration, the working body fixed to the engagement plate, for example, an orthodontic bullet or the like can act on a necessary portion of the tooth, and flexibility in the orthodontic treatment can be provided.

Further, the assisting tool has a pair of mounting portions, and the working body is an elastic wire, one end of which is fixed to one of the mounting portions, and the other end of which is fixed to the other of the mounting portions. Is also good. With such a configuration, the pair of attachment portions can both be fixed to the wire, and the wire between the pair of attachment portions can be cut. In other words, the use of the correction jig is expanded, and the mounting state of the treatment jig can be set to an optimal state for treating the patient.

Further, since the treatment can be easily performed in the oral cavity of the patient, the treatment time is short for the patient and the patient can easily receive the treatment. On the other hand, for the dentist, the treatment operation can be easily performed, so that the operation efficiency is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view for explaining an orthodontic treatment in dental care. One method of gradually improving the tooth arrangement is to fix a bracket B to the surface of a tooth T and pass a wire W between the brackets B, as shown in FIG. The wire W is slidably held on the bracket B. The elastic force of the wire W acts on the teeth T, and the arrangement of the teeth T is gradually improved.

FIG. 2 is a view for explaining an example of the structure of the bracket B and how to hold the wire W in the bracket B. The bracket B has a thin plate-shaped base 2 and two pairs of wings 3 and 4 provided on the surface of the base 2. A slot 5 is formed between each pair of wings 3 and 4. Slot 5 is as shown in FIG.
Are grooves for accommodating the wire W as shown in FIG.

The back surface of the base 2 is adhered to the front surface of the teeth T (see FIG. 1). Then, the wire W is inserted into the slot 5 of the bracket B, and the wire W and the wing 4 are wrapped by the extra-fine ligature wire 6 so that the wire W does not come off the slot 5. Even when wrapped by the ligature wire 6, the wire 2 is usually slidable with respect to the slot 5.

FIGS. 3 and 4 are schematic views showing specific examples of the orthodontic treatment. FIG. 3A shows the teeth T1 and T2.
An example of a procedure for packing between the (postmolar portion) and the teeth T3 and T4 (front teeth) is shown. A wire W is passed through brackets B1 to B4 fixed to the teeth T1 to T4, and a rear end 7 of the wire W is attached to the bracket B1. A hook 8 is brazed to the bracket B1. Further, a hook 9 is fitted to a front portion of the wire W. A coil spring 10 (or rubber) is hung between the hook 8 and the hook 9.
Accordingly, the force applied to the hook 9 acts on the wire W due to the elastic force of the coil spring 10 that contracts, and the wire W moves rearward along the bracket, and the wire W moves between the rear molars T1, T2 and the front teeth T3, T4. Close the space (this principle is called "sliding mechanics" in orthodontic practice).

FIG. 3 (B) shows the relationship between the teeth T1,
An example is shown in which the elastic force of the loop 11 formed on the wire W is used instead of the coil spring 10 to close the gap between T2 (rear molar part) and the tooth T3 (front tooth part) (in orthodontic practice). A loop formed on a wire to close a space is called a closing loop.) A claws group 11 is formed on the wire W, and a stopper 12 is brazed to a rear portion of the wire W. Bracket B1 attached to stopper 12 and tooth T1
By using the ligature wire 12a, the wire W on the rear side of the loop 11 moves rearward along the slots of the brackets B2 and B1, and the loop 11 is in an expanded state. Therefore, an orthodontic force is applied to the anterior teeth portion T3 rearward and to the posterior posterior teeth portions T1 and T2, whereby a gap between the anterior tooth portion T3 and the posterior posterior teeth portions T1 and T2 can be closed.

FIG. 4 exemplifies a treatment method when the distance between the teeth is increased. As shown in FIG. 4A, a coil spring 13 is disposed between the teeth T1 and T3 whose interval is to be increased. Specifically, the wire W is passed through the coil spring 13 so that the coil spring (opened coil) 13 is located between the bracket B1 and the bracket B3. Then, the force of the coil spring 13 to extend acts between the bracket B1 and the bracket B3, and the interval between the teeth T1 and T3 gradually increases. Thereafter, the tooth T2 is located between the widened teeth T1 and T3.
Place.

As shown in FIG. 4B, the treatment for widening the interval between the teeth can be performed by utilizing the elastic force of a loop formed on the wire W. The loop 14 is provided with elasticity to expand from a state shown by a solid line to a state shown by a broken line.
Then, the space between the teeth T1 and T3 can be expanded by the force of the loop 14 to expand. Note that the feet of the loop 14 are respectively attached to the brackets B so that the force for expanding the loop 14 acts between the brackets B1 and B3.
1, Bend to hit B3.

The above description is an example of the basic correction treatment. The coil spring and the wire W used for such treatment are described.
The present invention intends to provide an auxiliary tool that can be used in place of the loop formed in the above. 5 to 10 show specific examples of the assisting device according to the present invention. First, a description will be given with reference to FIG. FIG. 5A shows an example of an auxiliary tool. This auxiliary tool 20 has a mounting portion 21
And the action body 22 are included. The attachment portion 21 can be attached to the wire W attached to the bracket B described with reference to FIG. That is, it can be attached to the wire W in the patient's mouth.

For this purpose, the mounting portion 21 has a substantially U-shaped side surface, and has a mounting opening 23 through which the wire W can be inserted. The mounting opening 23 is fitted to the wire W, and pressure is applied to the mounting portion 21 in the vertical direction with a plier or the like. Then, the mounting portion 21 is securely attached to the wire W while holding the wire W therebetween. The working body 22 is connected to the mounting portion 21. The connection between the mounting portion 21 and the working body 22 is achieved by, for example, brazing, welding, or a metal adhesive.

For the working body 22, for example, a square wire is used, and a loop is formed. Tip 24 of action body 22
Is bent so that a ligature wire or the like can be hooked. The action body 22 may be made of a round wire instead of a square wire. After attaching the auxiliary tool 20 to the wire W, for example, a ligature wire is tied to the distal end 24 of the working body 22, and a desired bracket or the like and the distal end 24 of the working body 22 are connected by the ligature wire with a predetermined force.
Then, a force in the direction of arrow 25 is applied to a wire (not shown) to which the action body 22 is attached, and the wire can be slid in the direction of arrow 25. Conversely, a tooth with a predetermined bracket can be moved in the direction opposite to the arrow 25.

This makes it possible to close the space between the teeth in a manner similar to that described with reference to FIG. In addition, when this auxiliary tool 20 is used, the following disadvantages pointed out in the conventional manner can be improved. That is, when sliding mechanics is performed using a coil spring, food debris tends to accumulate in the coil spring. The food debris that has entered the coil spring is difficult to remove with a toothbrush or the like, and if the food debris remains, it is dirty and unsightly.

When the above-described auxiliary tool 20 is used, the auxiliary tool 20
Is not as hard to eat as coil springs,
Moreover, even if they adhere, they can be easily removed with a toothbrush or the like. When performing sliding mechanics using rubber,
The rubber denatures in about 3 to 4 days and loses its elasticity, so that no sustained efficacy is obtained. Therefore, the rubber had to be reapplied frequently.

When the above-described auxiliary tool 20 is used, there is no disadvantage such as rubber. When a closing loop is formed in a wire to close a space between teeth, a new wire needs to be created in order to form a loop. Therefore, there is a disadvantage that a chair time is required. By using the above-described auxiliary tool 20, the auxiliary tool can be attached to the wire attached to the teeth in the oral cavity. Therefore, the chair time is small.

FIGS. 5B, 5C, and 5D also show, respectively,
As in (A), it is composed of a mounting portion 21 and a working body 22, and the only difference is the shape of the working body 22. FIG. 6 shows another example of the assisting device. The auxiliary tool 30 of FIG. 6 includes, as an action body, an elastic wire 31 bent into a predetermined shape,
A pair of mounting portions 21 respectively connected to both ends of the elastic wire 31 are provided. The configuration of the mounting portion 21 is the same as that described with reference to FIG.

In the auxiliary tool 30 shown in FIG. 6, the shape, thickness, etc. of the elastic wire 31 may be changed depending on the use.
Further, the holding of the engaging portion may be adjusted depending on the application to be used, and may be fixed to the main wire or slid. Furthermore, in the figure, the elastic wire 31 is a relatively thin round wire, but a thicker round wire or a square wire may be used.

For example, a wire W mounted on a bracket
By using a more elastic wire (see FIG. 1), the coil 13 and the loop 11 shown in FIGS. 3A and 3B can be used instead. If a square wire is used, a bypass can be given to the main arch wire. FIG. 7 shows still another example of the assisting device. The auxiliary tool 40 shown in FIG. 7 includes the mounting portion 21 and an elastic wire 41 as an action body. (A) shows an example in which the elastic wire 41 is a round wire, and (B) shows an example in which the elastic wire 41 is a square wire.

The shape of the elastic wire 41 is merely an example, and may be any shape. In addition, when attaching the attaching portion 21 to the main wire, the auxiliary tool 40 can relax the holding force of the attaching portion 21 so that the attaching portion 21 can slide with respect to the main wire. 21
Can be mounted so that the mounting portion 21 is firmly fixed to the main wire.

The same applies to other auxiliary tools. FIG.
Shows other aids. The auxiliary tool 50 of FIG.
And an elastic wire 51 as an action body. The feature is that the elastic wire 51 is connected to the front of the mounting portion 21. Thus, depending on the application, the mounting portion 2
The action body can be connected to any one position.

FIG. 9 shows still another example of the assisting device. The auxiliary tool 60 in FIG. 9 is an example having two working bodies. 2
One effector is made of a square or round elastic wire. In the case of FIG. 9, one working body 61 is a relatively thick square wire, and the other working body 62 is a relatively thin round wire. Since not only one working body but also a plurality of working bodies can be mounted on the mounting portion 21 as necessary, if only necessary working bodies are connected to the mounting portion according to the use of the auxiliary tool. Good.

FIGS. 10A and 10B show an auxiliary tool according to still another embodiment of the present invention, wherein FIG. 10A is a front view, and FIG.
Is a right side view, and (C) is a plan view. This aid 70
Consists of a mounting part 21 and a tubular body 71 connected to the front of the mounting part 21. The mounting portion 21 and the cylindrical body 71 are connected by brazing or welding. Or the connecting part 21
And the cylindrical portion 71 may be integrally formed.

The assisting tool 70 is used as shown in FIGS. That is, the mounting portion 21 is fixed to the wire W mounted on the bracket. A sub-wire 72 is passed through the cylindrical body 71, and a distal end 73 thereof is bent to prevent the sub-wire 72 from falling out of the cylindrical body 71, and the sub-wire 72 is twisted at the other end side, thereby forming a cylindrical shape. Body 71
The sub-wire 72 is kept stationary. The distal end of the subwire 72 is attached to the bracket B1, for example, as shown in FIG.

Although the auxiliary member 70 shown in FIG. 10 is configured such that the cylindrical body 71 can insert a square wire, it may be configured so that a round wire can be inserted. FIG. 13 is a diagram illustrating a configuration example of the mounting portion 21. As shown in FIG. 13A, the mounting portion 21 has a substantially U-shaped side surface, and a wedge-shaped projection 26 is formed on the inner surface thereof. Although a plurality of protrusions 26 are formed in the figure, the number may be arbitrary. FIG. 13B shows a state in which the round wire W1 is sandwiched by the mounting portion 21.
FIG. 13C shows a state in which the square wire W2 is sandwiched.

When the mounting portion 21 clamps the wire W and there is the projection 26, the projection 26 bites into the wire W, and the mounting portion 21 is firmly fixed to the wire W. FIG.
As shown in FIG. 4 (A), a rim-shaped concave streak 28 may be formed in small increments at regular intervals on a wire W for attaching the attaching portion 21. Alternatively, as shown in FIG. 14 (B), dents (dimples) 27 may be formed on the peripheral surface of the wire W at regular intervals, for example.

That is, the wire W attached to the bracket
Instead of a normal wire having no irregularities on the surface, a special wire W as shown in FIG. 14 may be used. When such a wire W is used, the concave streak or dent on the surface of the wire W engages with the projection 26 formed on the mounting portion 21, so that the mounting portion can be more stably mounted on the wire W. FIG.
FIG. 5 shows an auxiliary tool according to still another embodiment. FIG.
The auxiliary tool 80 shown in FIG. 5 is an auxiliary tool 80 attached to the bracket B, unlike the auxiliary tools described above.

The assisting tool 80 includes an engaging plate 81 to be engaged with the bracket B, and an elastic wire 82 having one end fixed to the engaging plate. Engagement plate 8
Reference numeral 1 denotes a shape that can be fitted into a slot of the bracket B. As shown in FIG.
After fitting 1 into the slot of bracket B, engaging plate 81 is fixed to wings 3 and 4 with ligature wire 6.

Normally, the slot of the bracket B has a little room as well as a space for accommodating the main wire W.
Therefore, after the main wire W is accommodated in the slot, it is possible to fit the engagement plate from above. The elastic wire 82 as an action body can be variously deformed similarly to the above-described embodiment.
What is necessary is just to select the thickness and length of.
