Description

Orthodontic instruments and bite blocks {ORTHODONTIC INSTRUMENT AND BITE BLOCK}

The present invention relates to an orthodontic appliance and a bite block, and more particularly, to an orthodontic appliance capable of adjusting the gap between a tooth and a wire when performing an orthodontic treatment with a bracketless treatment, and a wire It is about a block of bytes that can be fixed.

In orthodontic treatment to treat malocclusion, most of the bracket orthodontic treatment methods are used. In the bracket orthodontic treatment method, a device called a bracket (10) is attached to each tooth (1), and the malocclusion is treated with orthodontic force using a wire (20) inserted into the bracket (10). This scheme is illustrated in FIG. 1 .

However, since the bracket 10 protrudes on the surface of the tooth 1, the patient has no choice but to feel a foreign body, and there is a problem that the bracket 10 may cause a wound in the oral cavity. In addition, when fixing the wire 20 to the bracket 10, a ligation wire or a rubber ring is used, and the corrective force of the wire 20 may be weakened by the frictional force generated at this time. In this case, there is a problem in that the effectiveness of orthodontic treatment is reduced and the orthodontic treatment period is also increased.

In order to solve these problems, a bracketless orthodontic treatment method that does not use a bracket has been recently introduced. This is shown in FIG. 3 . The bracketless orthodontic treatment is a method of manufacturing a dome-shaped resin 41 on the surface of the tooth 1 and inserting a wire 20 coated with a biodegradable material inside the resin 41 . When a certain period of time has elapsed after the procedure, the biodegradable material 43 is decomposed, and a gap 43 is formed between the wire 20 and the resin 41 . In this case, since the gap 43 exists between the wire 20 and the resin 41 , it is possible to maximize the orthodontic treatment effect by minimizing friction that weakens the orthodontic force of the wire 20 . In addition, since the resin 41 can be manufactured in a streamlined shape, it is possible to reduce the feeling of foreign body felt by the patient.

Meanwhile, when performing orthodontic treatment, the interval between the tooth 1 and the wire 20 may be set differently for each tooth 1 . At this time, the spacing between the teeth (1) and the wire (20) is called in-out (In-out). The reason that the in-out dimension is set differently for each tooth 1 is that the arrangement of the teeth 1 is not constant and the magnitude of the orthodontic force to be applied to each tooth 1 through the orthodontic treatment is different. to be.

As shown in Figure 2, in the conventional bracket orthodontic treatment, by inserting a separate base 30 between the bracket 10 and the tooth 1, the in-out interval (H) was appropriately adjusted. However, since the bracketless orthodontic treatment shown in FIG. 3 uses a method of applying the resin 41 to the surface of the tooth 1, there is a problem in that it is difficult to accurately set the interval H of the in-out.

In addition, since the resin 41 has viscosity, the wire 20 cannot be sufficiently fixed until it is completely cured. For this reason, the assistant must keep holding the wire 20 during orthodontic treatment, which causes an increase in treatment cost.

An object of the present invention is to provide an orthodontic appliance that allows an in-out interval to be accurately set when a bracketless orthodontic treatment is performed.

Another object of the present invention is to provide a bite block capable of fixing a wire without a separate assistant during bracketless orthodontic treatment.

However, the problems to be solved by the present invention are not limited to the above problems, and may be variously expanded within the scope without departing from the spirit and scope of the present invention.

4 is a view showing an orthodontic appliance according to an embodiment of the present invention. 5 is a view for explaining a method of adjusting the distance between the wire and the tooth using the orthodontic appliance of FIG. 4 .

4 and 5, the orthodontic appliance 100 according to the present invention is provided at both ends of the handle 110 of a cylindrical shape extending in one direction, and the handle 110 to fix the wire 20 It includes first and second fixing parts 120 and 130 .

The handle 110 has a cylindrical shape extending in the longitudinal direction, and an operator (eg, a doctor) performing orthodontic treatment may hold it by hand. At this time, a plurality of irregularities may be formed on the outer circumferential surface of the handle 110 to prevent slipping.

A first fixing part 120 may be provided at one end of the handle 110 , and a second fixing part 130 may be provided at the other end of the handle 110 . In this case, the first fixing part 120 may be bent by a first angle θ1 from the handle 110 , and the second fixing part 130 may be bent by a second angle θ2 from the handle 110 . can As described above, since the first fixing part 120 and the second fixing part 130 are bent by a predetermined angle, respectively, it is possible to increase the convenience of orthodontic treatment. In this case, the sizes of the first angle θ1 and the second angle θ2 may be appropriately selected as needed, and may be 180 degrees in some cases. An example in which both the first angle θ1 and the second angle θ2 are 180 degrees is illustrated in FIG. 6 .

The first fixing unit 120 and the second fixing unit 130 may support the wire 20 and adjust the in-out interval when bracketless orthodontic treatment is performed. In order to explain this more easily, first, the process of bracketless orthodontic treatment will be described in more detail.

Referring back to FIG. 3 , a predetermined amount of resin 41 is applied to the surface of the tooth 1 (first step). A wire 20 coated with a biodegradable material is attached on the applied resin 41, and the resin 41 is applied thereon again (second step). Thereafter, the dome-shaped resin 41 into which the wire 20 is inserted is formed (third step) through a curing process.

The first fixing part 120 and the second fixing part 130 of the present invention may be used in the second step and the third step. More specifically, in the second step, the first fixing part 120 and the second fixing part 130 are fixed so that the wire 20 does not move, and the resin 41 having viscosity on the wire 20 to be sufficiently applied. In particular, the first fixing unit 120 is not simply fixed to the wire 20, the distance between the teeth (1) and the wire 20, that is, the in-out interval can be selectively given. Also, in the third step, the second fixing part 130 may bend the wire 20 . The functions described above will be described again in more detail while explaining the structures of the first fixing part 120 and the second fixing part 130 .

First, the first fixing part 120 includes a first leg 121 and a second leg 126 spaced apart from each other. The resin 41 applied to the surface of the tooth 1 may be accommodated between the first leg 121 and the second leg 126 . That is, since the first fixing part 120 has a pair of legs 121 and 126 spaced apart from each other, it is possible to selectively fix only the wire 20 without contacting the resin 41 .

The first leg 121 may have a plurality of receiving grooves having different depths. The accommodating grooves are formed by having one end of the first leg 121 recessed inside, and a plurality of accommodating grooves may be formed. Accordingly, the first leg 121 may have a shape like a fork. The receiving grooves 122 and 123 serve to press the wire 20 during orthodontic treatment and may have different depths.

For example, as shown in FIG. 4 , the first leg 121 has a first receiving groove 122 having a first depth H1 and a second receiving groove 123 having a second depth H2. can In this case, the first depth H1 and the second depth H2 have different values, and may be a value frequently used for an in-out interval.

As shown in FIG. 5A , when the wire 20 is inserted into the first receiving groove 122 , the in-out interval may be set to a first depth H1 . Alternatively, as shown in FIG. 5B , when the wire 20 is inserted into the second receiving groove 123 , the in-out interval may be set to the second depth H2 . That is, the operator can adjust the in-out interval by selectively using the first receiving groove 122 or the second receiving groove 123 .

On the other hand, although it is shown that only the two receiving grooves 122 and 123 are formed in the first leg 121 in FIGS. 4 and 5 , the present invention is not limited thereto, and the number of the receiving grooves can be appropriately adjusted as needed can be changed. For example, three or more receiving grooves may be formed in the first leg 121 .

The second leg 126 is spaced apart from the first leg 121 and may have the same structure as the first leg 121 . That is, the second leg 126 may also have a third accommodating groove 127 and a fourth accommodating groove 128 having different depths. The third accommodating groove 127 has the same depth H1 as the first accommodating groove 122 , and the fourth accommodating groove 128 has the same depth H2 as the second accommodating groove 123 . can have

Since the first leg 121 and the second leg 126 fix the wire 20 at two points, the wire 20 can be more firmly fixed when the resin 41 is applied, and the in-out interval is constant. can be kept

The second fixing part 130 includes a third leg 131 and a fourth leg 136 that are spaced apart from each other. This is to selectively fix only the wire 20 without contacting the resin 41 , like the first fixing part 120 .

The third leg 131 may have a fifth receiving groove 132 having a third depth H3 and a first through hole 133 penetrating the third leg 131 . The fifth receiving groove 132 may be formed by recessing one end of the third leg 131 therein.

In one embodiment, the fifth receiving groove 132 may have a third depth H3, wherein the third depth H3 is different from the first depth H1 and the second depth H2. can have a value. That is, the operator can form an in-out interval having one value among the first to third depths (H1, H2, H3) by selectively using the first fixing part 120 and the second fixing part 130 . can

Alternatively, the in-out interval adjustment uses only the first fixing part 120 , and the second fixing part 130 may be used only for the purpose of simply fixing the wire 20 .

The first through hole 133 is formed through the third leg 131 and may be used to bend the wire 20 . Specifically, the operator may bend the wire 20 by inserting the distal end of the wire 20 into the first through hole 133 and applying a force to the handle 110 . That is, the first through hole 133 serves as a support, so that the wire 20 can be easily bent.

The fourth leg 136 is spaced apart from the third leg 131 and may have the same structure as the third leg 131 . That is, the fourth leg 136 may have a sixth receiving groove 137 and a second through hole 138 having a third depth H3 .

6 is a view showing an orthodontic appliance according to another embodiment of the present invention.

Referring to FIG. 6 , the orthodontic appliance 101 includes a handle 110 , a third fixing part 140 , and a fourth fixing part 150 . The third fixing part 140 may have a fifth leg 141 and a seventh accommodating groove 142 , and the fourth fixing part 150 includes a sixth leg 151 , an eighth accommodating groove 152 and It may have a third through hole 153 .

The orthodontic appliance 101 shown in FIG. 6 is basically the same as the orthodontic appliance 100 shown in FIG. 4, with only the following differences.

First, the angle between the third and fourth fixing parts 140 and 150 and the handle 110 is 180 degrees. That is, the third and fourth fixing parts 140 and 150 are not bent. As described above, the angle between the fixing part and the handle may be appropriately selected as needed, and the angle may be 180 degrees, which is illustrated in FIG. 6 .

Second, in the orthodontic appliance 100 of FIG. 4 , the receiving grooves 122 and 123 having different depths are provided together in one fixing part 120 . However, since the fixing part 120 has a narrow overall width, if too many receiving grooves are formed at once, the thickness of the remaining part is not sufficient, so the force for fixing the wire 20 may be weakened, and in some cases, it may be damaged. There are concerns. Accordingly, in FIG. 6, only one receiving groove is formed in one fixing part.

However, in order to adjust the in-out interval, the seventh receiving groove 142 of the third fixing part 140 is formed to a fourth depth H4, and the eighth receiving groove of the fourth fixing part 150 ( 152 is formed at a fifth depth H5 different from the fourth depth H4. Accordingly, the in-out interval may be adjusted as necessary.

Meanwhile, in FIGS. 4 and 6 , it is shown that the fixing parts are formed on both sides of the handle 110 , but the fixing parts may be formed on only one side of the handle 110 differently from this, and the shape is the first to fourth fixing parts ( 120, 130, 140, 150). In addition, fixing parts are formed on both sides of the handle 110 , and any two of the four fixing parts 120 , 130 , 140 , 150 may be combined.

As described above, the orthodontic instruments 100 and 101 according to the present invention support the wire 20 when performing an orthodontic treatment to improve the convenience of the treatment and shorten the treatment time. In particular, by being provided with a plurality of receiving grooves having different depths, it is possible to easily adjust the in-out interval even in bracketless orthodontic treatment. Accordingly, it is possible to secure an optimal in-out interval suitable for each tooth, to improve the effect of orthodontic treatment, and to reduce the period of orthodontic treatment.

On the other hand, the above-described orthodontic appliances 100 and 101 can adjust the in-out interval in the bracketless orthodontic treatment procedure, and can fix the wire 20 when the resin 41 is applied. However, such a wire 20 fixing function is inevitably limited to a narrow area around each tooth 1, and it is impossible to fix the long wire 20 as a whole. Hereinafter, the bite block 200 capable of fixing the wire 20 as a whole while the bracketless orthodontic treatment is in progress will be described.

7 is a diagram illustrating a byte block according to an embodiment of the present invention, and FIG. 8 is a diagram illustrating an example to which the byte block of FIG. 7 is applied.

7 and 8, the bite block 200 according to the present invention is a support 210 interposed between the upper and lower teeth, the inner extension 220 extending up and down from both sides of the support 210 and the outer It includes an extension part 230 , and a wire fixing part 240 protruding from the outer extension part 230 to fix the wire 20 .

The support part 210 has a plate shape, and the upper teeth may contact the upper surface and the lower teeth may contact the lower surface. That is, the support 210 can secure a space required for orthodontic treatment by maintaining a constant distance between the upper and lower teeth.

The inner extension 220 extends up and down from one end of the support 210 , and may face the inner surfaces of the upper and lower teeth. The outer extension part 230 extends up and down from the other end of the support part 210 and may face the outer surfaces of the upper and lower teeth. That is, the inner extension 220 and the outer extension 230 extend upward to a position higher than the upper surface of the support unit 210 , and extend downwardly to a position lower than the bottom surface of the support unit 210 . Accordingly, when the patient bites the support 210 with his mouth open, the inner extension 220 and the outer extension 230 face the inner and outer surfaces of the tooth 1, respectively, so that the support 210 moves into the oral cavity. It can be prevented from entering or falling out.

The wire fixing part 240 is formed on the surface of the outer extension part 230, the body 241 extending up and down along the outer extension part 230, and fixing holes 243 penetrating the body 241, 244) may be included.

On the other hand, the first fixing hole 243 is provided in the upper portion of the body 241, which is for fixing the wire 20 used when correcting the upper teeth. Therefore, it is preferable that the first fixing hole 243 is formed at a position higher than the upper surface of the support part 210 .

The second fixing hole 244 is provided in the lower portion of the body 241, which is for fixing the wire 20 used when correcting the lower teeth. Accordingly, the second fixing hole 244 is preferably formed at a lower position than the bottom surface of the support portion 210 .

As shown in FIG. 8, when the operator inserts the wire 20 into the first and second fixing holes 243 and 244, the wire 20 is fixed during orthodontic treatment without a separate assistant. can

In an embodiment, a plurality of wire fixing parts 240 may be provided on the outer extension part 230 . When there are a plurality of wire fixing parts 240 , the fixing force for the wire 20 may be increased, and the wire 20 may be more firmly fixed.

In an embodiment, the front surface 245 of the wire fixing part 240 may have a constant inclination θ3 with respect to the front surface of the outer extension part 230 . This is to improve the fixing force to the wire (20). Specifically, when the wire 20 is inserted into the fixing holes 243 and 244 in the direction perpendicular to the front surface 245 of the wire fixing unit 240 , there is no binding force on the wire 20 during the procedure. ) may be removed from the fixing holes 243 and 244 . In order to solve this problem, in the present invention, a slope θ3 is formed on the front surface 245 of the fixing part 240 . In this case, since the wire 20 is bent and inserted into the fixing holes 243 and 244 , the binding force on the wire 20 can be strengthened, and the wire 20 can be prevented from falling out during the procedure.

As described above, the bite block 200 according to the present invention can firmly fix both ends of the wire 20 in a bracketless orthodontic procedure that does not use a bracket. Therefore, orthodontic treatment can be performed more quickly and stably, and there is no need to have a separate assistant for fixing the wire 20 .

Although the above has been described with reference to the embodiments of the present invention, those skilled in the art can variously modify and change the present invention within the scope without departing from the spirit and scope of the present invention described in the claims below.
