Description

[Technical Field]

[0001] The present invention relates to a method for producing an orthodontic bracket used for orthodontic treatment, and an orthodontic treatment method using the orthodontic bracket. [Background technology]

[0002] Conventionally, orthodontic treatment involves wire orthodontics, which uses a jig called a bracket that is attached to the teeth of the patient and an orthodontic wire that is inserted into insertion holes or grooves in the bracket, and mouthpiece orthodontics, which corrects the alignment of the teeth by covering the entire alignment of the teeth by successively replacing multiple mouthpieces that are formed in several small stages to move the teeth from the original alignment to the desired ideal alignment.

[0003] In the above-mentioned wire orthodontic method, brackets smaller than the teeth are attached to the tooth surfaces (lingual or cheek sides) of the patient using dental adhesive, and an orthodontic wire is inserted through insertion holes or grooves provided in the brackets.

[0004] The orthodontic wire used in this case is an elastic member, and is formed in advance into an arch shape that conforms to the desired ideal tooth alignment.

[0005] Therefore, due to the orientation and angle of the insertion holes and grooves of the brackets attached to the teeth of the patient, the original arch shape cannot be maintained when the brackets are inserted, and as a result, a restoring force acts on the orthodontic wire, trying to return it to its original arch shape.

[0006] This restoring force is transmitted to the teeth of the patient via the brackets, and the teeth move to achieve the desired ideal alignment, thereby achieving orthodontic treatment.

[0007] However, because the brackets commonly used are pre-made, the surface on which the bracket is attached to the teeth is not shaped to fit the individual teeth of the patient, and attaching the bracket is a delicate process that requires high skill.

[0008] Therefore, in our previous application (see Patent Document 1), we solved this problem by creating brackets using dental resin that fit the uneven shape of the tooth surface for each patient to be treated.

[0009] Furthermore, with regard to mouthpiece orthodontics, a technique has been disclosed in which an orthodontic mouthpiece is produced based on the actual dentition data of a patient to be treated (see Patent Document 2).

[0010] This technology scans the patient's pre-orthodontic dentition, and then uses that data to simulate the process of achieving the desired ideal dentition on a computer, making it possible to create orthodontic mouthpieces tailored to each individual patient.

[0011] Furthermore, because the orthodontic appliance is in the form of a mouthpiece, there is no longer any need to rely on high levels of skill for treatment, as was the case with conventional wire orthodontics. [Patent Document 1] Patent Publication No. 2012-66016 [Patent Document 2] Special Publication 2002-526155 Summary of the Invention [Problem to be solved by the invention]

[0012] The above-mentioned Patent Documents 1 and 2 can facilitate treatment involving wearing a corrective appliance.

[0013] Furthermore, the wire orthodontic method using Patent Document 1 has few limitations on the position where the brackets can be attached, which has the advantageous effect of allowing positioning to be performed taking into consideration not only the shape of the patient's teeth but also their bite habits.

[0014] Furthermore, the mouthpiece orthodontic method described in Patent Document 2 has the favorable effect of ensuring aesthetics, which is a drawback of wire orthodontics.

[0015] However, both of these methods have the problem that a long preparation period is required before the orthodontic appliance can be fitted to the patient.

[0016] More specifically, the wire orthodontic method using brackets described in Patent Document 1 involves taking a mold of the patient's pre-orthodontic dentition using an impression material, and then creating a pre-orthodontic dental model from the mold.

[0017] Next, each tooth is separated from the pre-correction dental arch model and rearranged into the desired ideal dental arch to create an ideal dental arch model.

[0018] Then, the position for attaching the brackets is determined using an ideal dental arch model, the brackets are created using dental resin, and the completed brackets are attached to the actual teeth of the patient, finally leading to the attachment process.

[0019] In the orthodontic method using a mouthpiece described in Patent Document 2, first, the oral cavity of the patient to be treated is scanned and the scanned data is input into a computer as 3D data.

[0020] Next, the imported 3D data is separated into individual teeth on a computer and rearranged into the desired ideal tooth alignment.

[0021] The tooth movement from the original alignment to the ideal alignment is then divided into multiple stages, and an orthodontic mouthpiece is created based on data from each stage, and finally fitted.

[0022] This preparation period is similar to that for conventional wire orthodontics, and requires taking impressions or scanning the mouth to create an actual model.

[0023] However, the difficulty of orthodontic treatment varies depending on the patient, and some patients require long-term orthodontic treatment, while others can be completed in a relatively short period of time.

[0024] Even in cases where orthodontic treatment can be completed in a relatively short period of time, the long preparation period mentioned above is required, which results in various problems being imposed on the patient, such as increased treatment costs and a longer period of inconvenience due to malocclusion.

[0025] Furthermore, in orthodontic methods using a mouthpiece such as that in Patent Document 2, the teeth requiring orthodontic treatment are pressed by the mouthpiece that is fitted over the dental arch, gradually moving the teeth in the corrective direction. Therefore, it may be difficult or impossible to transmit the force required for orthodontics, such as extrusion and depression, which require transmitting force in the vertical direction to the teeth to align the height of the upper surfaces of the teeth, straightening, which requires transmitting force in an obliquely upward direction to the teeth to straighten tilted or fallen teeth, or orthodontic treatment involving rotation, which requires transmitting force in a rotational direction to the teeth to change the direction of the tooth surfaces.

[0026] In cases like the above, after treatment with mouthpiece orthodontics, it may be necessary to undergo wire orthodontics again or surgery, which again requires a dental model, further extending the time until treatment is completed.

[0027] Among all the teeth, molars have occlusal surfaces, which have an uneven shape. This uneven shape has a concave portion in the center of the molars, and the more ideal the teeth are, the more they are arranged in such a way that connecting the concave portions with lines forms a neat arch.

[0028] The present invention has been made in consideration of the above circumstances, and aims to provide a method for making an orthodontic bracket that allows treatment to be performed quickly on a patient without requiring a long preparation period, and an orthodontic method using the orthodontic bracket, in which an orthodontic bracket for performing orthodontic treatment is composed of an orthodontic wire insertion tube and an orthodontic bracket main body, the orthodontic wire insertion tube is placed in the central recess of the occlusal surface of the molar of the patient, the orthodontic bracket is formed by depositing a thick layer of dental resin from above the orthodontic wire insertion tube and hardening it, and then cutting the front and rear ends of the orthodontic bracket to expose the openings at both ends of the orthodontic wire insertion tube to form insertion holes for inserting the orthodontic wire. [Means for solving the problem]

[0029] In order to solve the above-mentioned conventional problems, the orthodontic bracket of the present invention comprises an orthodontic wire insertion tube and an orthodontic bracket main body, the orthodontic wire insertion tube is placed in the central recess of the occlusal surface of the molar of the patient to be treated, the orthodontic bracket is formed by depositing a thick layer of dental resin from above the orthodontic wire insertion tube and hardening it, and further, the front and rear ends of the orthodontic bracket are cut to expose the openings at both ends of the orthodontic wire insertion tube, thereby forming through holes for inserting the orthodontic wire. A method for making an orthodontic bracket and an orthodontic method using the orthodontic bracket are provided, characterized in that [Effects of the Invention]

[0030] According to the orthodontic bracket of the present invention, the orthodontic bracket is composed of an orthodontic wire insertion tube and an orthodontic bracket main body, and the orthodontic wire insertion tube is placed in the central recess of the occlusal surface of the molar of the patient to be treated. The orthodontic bracket is formed by depositing a thick layer of dental resin from above the orthodontic wire insertion tube and allowing it to harden, thereby making it possible to create an orthodontic bracket directly on the occlusal surface of the molar of the patient to be treated, and orthodontic treatment can be performed in the shortest time possible without the need for long-term preparations such as creating a model or designing a mouthpiece.

[0031] In addition, the orthodontic wire insertion tube is placed in the central recess of the occlusal surface of the molar of the patient, and the orthodontic bracket is formed by applying a thick layer of dental resin above the orthodontic wire insertion tube and allowing it to harden, allowing partial orthodontic treatment of the molars to begin quickly and significantly shortening the time it takes to complete orthodontic treatment compared to conventional orthodontic methods.

[0032] Furthermore, with conventional mouthpiece orthodontics, movements involving extension, intrusion, straightening, and rotation of molars were difficult to achieve, and wire orthodontics, which requires a preparation period, had to be performed again before or after mouthpiece orthodontics, resulting in an even longer period of time until orthodontics was completed. However, with the orthodontic brackets of the present invention, even when used in combination with mouthpiece orthodontics to compensate for the shortcomings of mouthpiece orthodontics, orthodontic treatment can be completed in a shorter period of time than conventional methods, thereby reducing the burden on the patient being treated.

[0033] Furthermore, with conventional bracket orthodontics, brackets smaller than the teeth are attached at predetermined positions and angles, which requires advanced skills. However, with this system, positioning is completed by placing the orthodontic wire insertion tube on the occlusal surface of the molar, and a thick layer of resin is applied on top of this orthodontic wire insertion tube to create the bracket, which does not require advanced skills and makes treatment easier.

[0034] Furthermore, with conventional bracket orthodontics, in which brackets are attached to the tongue and cheek sides, it is difficult to determine the bracket position for straightening, i.e., straightening fallen teeth. If the brackets are attached above the correct position, the raised teeth will have unnecessary downward force due to the restoring force of the orthodontic wire, and conversely, if the brackets are attached below the correct position, the raised teeth will have unnecessary upward force due to the restoring force of the orthodontic wire. In either case, the upper surfaces of the teeth will not be aligned, resulting in incomplete orthodontics. However, by attaching brackets to the occlusal surfaces of the molars, i.e., the upper surfaces of the teeth, force is transmitted so that the upper surfaces naturally align due to the restoring force of the orthodontic wire when straightening, which has the effect of enabling correct orthodontics.

[0035] Furthermore, with conventional bracket orthodontics, which involves attaching brackets to the tongue and cheek sides, and performing rotational correction, i.e., correcting the orientation of the tooth surface, brackets cannot be attached to the surface where the tooth requiring orthodontic treatment is in contact with the adjacent tooth, i.e., a surface that is not normally visible, so there is a limit to the rotational movement that can be performed in one go, and if the rotational movement is insufficient, it is necessary to change the position of the bracket again after the first orthodontic treatment and perform orthodontics a second time. However, by attaching brackets to the occlusal surfaces of the patient's molars, there is no limit to the bracket position that transmits the rotational movement, and orthodontic treatment that rotates the teeth can be completed in one go.

[0036] In addition, because the orthodontic brackets are formed on the occlusal surfaces of the patient's teeth, they inhibit the patient from chewing forcefully during the orthodontic treatment period, and relax the muscles and gums around the jaw, making it easier to move the teeth requiring orthodontic treatment.

[0038] The gist of this invention is a method for making an orthodontic bracket for a patient and an orthodontic method using the orthodontic bracket, wherein the orthodontic bracket is composed of an orthodontic wire insertion tube and an orthodontic bracket body, the orthodontic wire insertion tube is placed in the central recess of the occlusal surface of the patient's molar, the orthodontic bracket is formed by depositing a thick layer of dental resin from above the orthodontic wire insertion tube and hardening it, and further the front and rear ends of the orthodontic bracket are cut to expose the openings at both ends of the orthodontic wire insertion tube, thereby forming a through hole for inserting the orthodontic wire.

[0039] An embodiment of the method for producing an orthodontic bracket according to the present invention will be described in detail below with reference to the drawings. Fig. 1 is a schematic perspective view showing the state in which the orthodontic bracket according to the present invention is attached. Fig. 2 is a schematic perspective view showing an orthodontic wire insertion tube for the orthodontic bracket according to the present invention. Figs. 3 and 4 are schematic perspective views illustrating the method for producing an orthodontic bracket according to the present invention. Fig. 5 is a schematic cross-sectional view showing the configuration of the orthodontic bracket according to the present invention. Fig. 6 is a schematic plan view showing the state during orthodontic treatment and when orthodontic treatment is completed.

[0040] (About the structure of orthodontic brackets) The orthodontic bracket M according to the present invention will now be described in detail. As shown in FIG. 1, an orthodontic bracket M according to the present invention is placed and fixed on the occlusal surface B of a molar in the dentition T of a patient to be treated.

[0041] The orthodontic bracket M is composed of an orthodontic wire insertion tube 1 that is placed directly on the occlusal surface B of a molar, and an orthodontic bracket main body 2 that is thickly formed so as to cover the orthodontic wire insertion tube 1 from above.

[0042] As shown in FIG. 2, the orthodontic wire insertion tube 1 is made of a material that is resistant to corrosion and heat, such as stainless steel, and is formed into a cylindrical shape with a diameter of about 1 to 2 mm and a total length of about 3 to 6 mm.

[0043] In addition, the shape of the cylindrical opening is approximately rectangular, similar to the cross section of the orthodontic wire 3 described later, and the hole of this orthodontic wire insertion tube 1 functions as an insertion hole 11 for inserting the orthodontic wire 3.

[0044] The molar occlusal surface B on which the orthodontic wire insertion tube 1 is placed has a recess b in the center of the tooth as shown in FIG. 3a.

[0045] Therefore, when placing the orthodontic wire insertion tube 1, as shown in FIG. 3b, it is placed on the molar occlusal surface B and at the same time rolls into the recess b at the bottom of the uneven shape, and is naturally positioned.

[0046] Furthermore, when placing this orthodontic wire insertion tube 1 in the recess b of the molar occlusal surface B, it is also possible to fill the insertion hole 11 with Vaseline or the like in advance to prevent it from being blocked by the dental resin 21 that will cover it from above in the next process.

[0047] As shown in FIG. 4, the orthodontic bracket body 2 is formed by depositing a dental resin 21 thickly on top of the orthodontic wire insertion tube 1 placed in the recess b of the occlusal surface B of the molar.

[0048] The dental resin 21 is used as a filling material to close holes drilled in the tooth surface during treatment of cavities or the like, and is a photo-curable material, such as an ultraviolet-curable resin.

[0049] When actually making the orthodontic bracket body 2, as shown in FIG. 4a, first, a thick layer of dental resin 21 is applied to cover the orthodontic wire insertion tube 1 placed on the occlusal surface B of the molar.

[0050] Next, the dental resin 21 is irradiated with ultraviolet light from a UV light or the like to harden it.

[0051] Then, as shown in Figure 4b, the dental resin 21 is cut so that both ends of the orthodontic wire insertion tube 1 in the hardened dental resin 21, i.e., the insertion hole 3 for inserting the orthodontic wire 3, are exposed.

[0052] By doing so, the orthodontic bracket M is formed so that the dental resin 21 encloses the orthodontic wire insertion tube 1 as shown in FIGS. 4b and 5.

[0053] Furthermore, when applying a thick layer of dental resin 21 to the molar occlusal surface B, dental adhesive can be applied to the molar occlusal surface B beforehand, thereby allowing the formed orthodontic bracket body 2 to be more firmly fixed to the molar occlusal surface B of the patient.

[0054] During orthodontic treatment, as shown in FIG. 6, the orthodontic wire 3 is sequentially inserted through the insertion holes 11 formed in the orthodontic wire insertion hole 1 in the orthodontic bracket M prepared by the above method.

[0055] The orthodontic wire 3 to be inserted at this time is made of elastic metal, such as stainless steel, and is bent in advance into an arch shape that represents an ideal state of dental arch.

[0056] As shown in FIG. 6a, the inserted orthodontic wire 3 cannot maintain its original arch shape and becomes distorted and bent.

[0057] Then, the orthodontic wire 3 moves and corrects the dentition T by the restoring force that tries to return it to its original arch shape, and finally, the correction is completed as shown in FIG. 6b.

[0058] Furthermore, in actual orthodontics, correction is not completed with a single orthodontic wire 3; for example, multiple types of orthodontic wires 3 with small diameters may be prepared, and correction may be performed in stages, starting with the smallest diameter.

[0059] Furthermore, when performing correction in stages, it is advisable to bend and shape the orthodontic wire 3 appropriately during the examination, rather than forming all of the orthodontic wires 3 to have the same arc shape from the beginning.

[0060] The orthodontic wire 3 may be the same as the orthodontic wire used in conventional bracket orthodontic methods, and preferably has a substantially rectangular cross-sectional shape so as not to rotate within the insertion hole 11, but is not limited to this and may have a circular cross-sectional shape, etc. In this case, the insertion hole 11 through which the orthodontic wire 3 is inserted may also be changed appropriately to match its shape.

[0061] (Regarding the orthodontic bracket procedure) Next, an orthodontic procedure using the orthodontic bracket M according to the present invention will be described in detail. FIG. 7 is a flow chart showing an orthodontic procedure using the orthodontic bracket M according to the present invention.

[0062] As shown in Figure 7, the orthodontic procedure for the orthodontic bracket M consists of an orthodontic wire insertion tube placement step S41 in which an orthodontic wire insertion tube is placed on the occlusal surface of the molar including the tooth t requiring orthodontic treatment; a bracket body creation step S42 in which a thick layer of dental resin is applied to the occlusal surface to create the bracket body; an insertion hole formation step S43 in which the front and rear ends of the bracket body are cut to form insertion holes for inserting the orthodontic wire; an orthodontic wire insertion step S44 in which the orthodontic wire is inserted into the insertion hole; and an orthodontic bracket removal step S5 in which the orthodontic wire and orthodontic bracket are removed after the orthodontic treatment is completed.

[0063] The orthodontic wire insertion tube placing step S41 is a process of placing the orthodontic wire insertion tube 1 on the occlusal surface B of the molar including the tooth t requiring orthodontic treatment, as described above in the configuration of the orthodontic bracket M.

[0064] Since the orthodontic wire insertion tube 1 is cylindrical, even if the placement position is different, it rolls on the molar occlusal surface and rolls to the most recessed part b of the surface irregularity located in the center of the molar occlusal surface B.

[0065] That is, by placing it on the upper part of the molar occlusal surface B, it will naturally roll over the upper surface and be placed in the correct position.

[0066] The bracket body preparation step S42 includes a dental resin thickening step S42-1 and a dental resin hardening step S42-2.

[0067] The dental resin depositing step S42-1 is a step in which dental resin 21 is deposited thickly on the molar occlusal surface B to form the shape of the bracket main body 2.

[0068] More specifically, the dental resin 21 is deposited thickly so as to cover the orthodontic wire insertion tube 1 placed in the most recessed portion b of the molar occlusal surface B in the orthodontic wire insertion tube placing step S41.

[0069] At this time, if it is desired to enhance the effect of orthodontic treatment by inhibiting mastication during the orthodontic treatment, the dental resin 21 should be applied thicker than the convex portion of the occlusal surface B of the molar.

[0070] The dental resin hardening step S42-2 is a step for hardening the dental resin 21 that has been applied thickly to the molar occlusal surface B in the dental resin application step S42-1.

[0071] The dental resin 21 is a light-curing material, such as a composite resin used in treating dental caries.

[0072] This dental resin 21 is hardened by irradiating it with UV light, and the bracket body 2 can be produced.

[0073] The insertion hole forming step S43 is a step for cutting away unnecessary portions of the bracket main body 2 created by irradiating it with UV light in the dental resin hardening step S42-2, thereby forming the orthodontic bracket M.

[0074] The dental resin 21 deposited thickly in the dental resin depositing step S42-1 is hardened in the dental resin hardening step S42-2 so as to cover the orthodontic wire insertion tube 1.

[0075] Therefore, the hole formed in the orthodontic wire insertion tube 1 is buried in the bracket body 2.

[0076] Therefore, unnecessary portions of the hardened dental resin 21 are cut and removed so that the holes formed in the orthodontic wire insertion tube 1 are exposed.

[0077] The hole of the orthodontic wire insertion tube 1 exposed in this step becomes the insertion hole 11 for inserting the orthodontic wire 3 in the next step.

[0078] At the same time, any excess unevenness that may have formed during the thickening process or that may have adhered to other teeth is also removed.

[0079] Furthermore, the production of the orthodontic bracket M of the present invention is completed at this insertion hole forming step S43.

[0080] Since the orthodontic bracket M is adapted to the orientation and angle of the teeth before orthodontics at the manufacturing stage, the insertion holes 11 are oriented in various directions.

[0081] The orthodontic wire insertion step S44 is a step of inserting the orthodontic wire 3 into the orthodontic bracket M prepared by the orthodontic wire placement step S41 to the insertion hole forming step S43 described above.

[0082] The orthodontic wire 3 that is inserted is made of an elastic material and can be bent into an arc that simulates an ideal tooth alignment.

[0083] The orthodontic wire 3 bent into an arc shape is sequentially inserted into the insertion holes 11 of the orthodontic bracket M, and is bent distorted in various directions in which the insertion holes 11 face.

[0084] The orthodontic wire 3 that has been bent distorted in various directions is made of an elastic material, so a restoring force acts to return it to its original arc shape formed under an ideal condition.

[0085] The restoring force is transmitted to the teeth via the orthodontic bracket M, resulting in corrective movement. Furthermore, as described in the configuration of the orthodontic bracket M, the orthodontic wire 3 may be divided into a plurality of stages with different wire thicknesses.

[0086] The orthodontic bracket removal step S45 is a process in which the orthodontic treatment is completed when the orthodontic wire 3 returns to its original arc shape due to the restoring force, and the orthodontic wire 3 and orthodontic bracket M are removed from the dentition T of the patient.

[0087] This step completes orthodontic treatment using the orthodontic bracket M of the present invention.

[0088] As described above, the orthodontic bracket M of the present invention allows partial orthodontic treatment of molars to begin in the shortest possible time.

[0089] Furthermore, if the symptoms of malocclusion are mild, correction can be completed using only the orthodontic method using the orthodontic bracket M of the present invention, but it is not necessarily necessary to complete the correction using only the orthodontic method using the orthodontic bracket M of the present invention.

[0090] In other words, if orthodontic treatment requires a long period of time, it can be combined with other orthodontic methods and used as supplementary orthodontic treatment until the orthodontic treatment is complete.

[0091] For example, in the case of orthodontic methods using mouthpieces, it is difficult or impossible to perform orthodontic procedures for molar correction, such as extrusion and intrusion to align the height of the upper surfaces of the teeth, straightening teeth that have fallen into a tilted position, and moving teeth that require orthodontic treatment, which involves rotation to change the direction of the teeth.

[0092] In such cases, wire orthodontics or surgical procedures are usually performed before or after mouthpiece orthodontics.

[0093] However, in order to perform wire orthodontics separately, a second examination must be conducted to determine the treatment plan, which is not an efficient method.

[0094] Therefore, when performing mouthpiece orthodontics, the orthodontic method using the orthodontic bracket M of the present invention can be used to smoothly correct the molar area, which is difficult to correct in advance, thereby allowing the teeth T to be corrected smoothly.

[0095] Furthermore, the various effects described above are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the present embodiment. [Explanation of symbols]
