Description

Method, device, and recording medium for providing information related to the torque angle of a bracket

[0001] The present disclosure relates to a method for providing information related to the torque angle of a bracket. More specifically, it relates to a technique for determining the torque angle of a bracket based on information regarding the malocclusion state of the teeth and the orthodontic method.

[0002]

[0003] Currently, MBT and Roth brackets are primarily used for orthodontic treatment, and the torque of the bracket is fixed according to a specific process for each.

[0004] However, MBT and Roth brackets cannot be considered to have fully taken into account factors such as tooth extraction or non-extraction, classification of malocclusion, use of mini-screws, and the position of the central incisors in the patient's initial oral condition; consequently, additional bracket reattachment or wire adjustment becomes necessary during the course and final stages of orthodontic treatment.

[0005] Accordingly, there is a need for technology that recommends the optimal bracket specifications to achieve the predicted alignment state of teeth by predicting the alignment state of teeth after orthodontic treatment.

[0006] [Prior Art Literature]

[0008] Korean Registered Patent No. 10-1097638 (December 15, 2011) Method for controlling the fabrication of an orthodontic device for orthodontic treatment and a recording medium, and an orthodontic treatment system

[0009]

[0010] One embodiment of the present disclosure aims to solve the problems of the aforementioned prior art and to provide a method, device, and recording medium for determining the torque angle of a bracket based on information regarding the malocclusion state of the teeth and the orthodontic method.

[0011] The technical problems to be solved are not limited to those described above, and may include various additional technical problems within the scope obvious to ordinary users.

[0012]

[0013] A method for providing information related to the torque angle of a bracket in the first aspect of the present disclosure may include: a step in which a processor obtains information on the malocclusion state of teeth, which is determined according to the patient's tooth condition and indicates the positional relationship between the maxilla and the mandible; a step in which the processor obtains information on the orthodontic method, which includes information on the movement method of the central incisors indicating at least one of lingual tipping, bodily movement, and root movement, whether extraction is necessary, and whether a screw is necessary; a step in which the processor determines a torque angle determined according to the angle between the base portion and the wire slot of a bracket used for orthodontics based on the malocclusion state information and the orthodontic method information; and a step of displaying information on the torque angle.

[0014] In addition, the step of determining the torque angle may determine the tooth condition as one of the correct occlusion state, maxillary protrusion state, and mandibular protrusion state based on the malocclusion state information, and determine the torque angle based on the tooth condition.

[0015] In addition, if the tooth condition is determined to be the maxillary protrusion condition based on the above malocclusion condition information, the torque angle for the maxilla can be determined as high torque.

[0016] In addition, if the tooth condition is determined to be the maxillary protrusion condition according to the above malocclusion condition information, the torque angle for the mandible can be determined as low torque.

[0017] In addition, the above torque angle can be determined as any one of a high torque angle, a standard torque angle, and a low torque angle.

[0018] In addition, the step of determining the torque angle may determine the tooth condition as one of the correct occlusion state, maxillary protrusion state, and mandibular protrusion state based on the malocclusion state information, and determine the torque angle based on the tooth condition.

[0019] In addition, the step of determining the torque angle may determine the torque angle when a screw is required to be larger than the torque angle when a screw is not required.

[0020] In addition, the step of determining the torque angle may determine the torque angle when extraction is required to be larger than the torque angle when extraction is not required.

[0021] In addition, the step of determining the torque angle may determine the torque angle when the incisor movement method is the tooth body movement to be larger than the torque angle when the incisor movement method is the inclined movement.

[0022] In addition, the step of determining the torque angle may determine the torque angle when the incisor movement method is the tooth axis movement to be larger than the torque angle when the incisor movement method is the tooth body movement.

[0023] A device for providing information related to the torque angle of a bracket according to a second aspect of the present disclosure may include a processor that acquires information on the malocclusion state of teeth, which is determined according to the patient's tooth condition and indicates the positional relationship between the upper and lower jaws, acquires information on the orthodontic method, which includes information on the incisor movement method indicating at least one of lingual tipping, bodily movement, and root movement of the incisors, whether extraction is necessary, and whether a screw is necessary, determines a torque angle determined according to the angle between the base portion and the wire slot of a bracket used for orthodontics based on the malocclusion state information and the orthodontic method information, and displays information on the torque angle.

[0024] A third aspect of the present disclosure may provide a computer-readable recording medium storing a program for executing the method according to the first aspect on a computer. Alternatively, a fourth aspect of the present disclosure may provide a computer program stored on a recording medium for implementing the method according to the first aspect.

[0025]

[0026] By determining the bracket torque angle by considering various conditions during orthodontic treatment (such as whether extractions are performed, classification of malocclusion, use of screws, and initial central incisor position), there is an advantage in reducing the frequency of bracket reattachment or wire adjustment during the final stage of treatment.

[0027] In addition, there is an advantage in that efficient orthodontic treatment is possible by virtually simulating the position of the teeth after orthodontic treatment on software that virtually simulates the position of the teeth, predicting the patient's condition after orthodontic treatment, and recommending bracket specifications with the optimal torque angle to reach that predicted condition.

[0028] The effects of the present disclosure are not limited to the effects described above, and should be understood to include all effects that can be inferred from the detailed description of the present disclosure or the configuration of the disclosure as described in the claims.

[0040] The advantages and features of the present disclosure and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings.

[0044] A plurality of embodiments will be described in detail below with reference to the drawings.

[0045]

[0046] FIG. 1 is a block diagram showing an example of the configuration of a device (100) according to one embodiment.

[0047] Referring to FIG. 1, the device (100) may include memory (110) and a processor (120).

[0048] A person skilled in the art will understand that, in addition to the components illustrated in FIG. 1, other general-purpose components may be further included in the device (100). For example, the device (100) may include a drive control module, a data processing module, etc., for performing each step, and may include a sensing unit for acquiring sensing data from a plurality of sensors. Alternatively, a person skilled in the art will understand that, according to other embodiments, some of the components illustrated in FIG. 1 may be omitted.

[0049] A processor (120) according to one embodiment can acquire and determine various data. For example, the processor (120) can acquire malocclusion state information from the patient's tooth condition and acquire correction method information for the patient's teeth and store it in memory (110). In addition, the processor (120) according to one embodiment can determine the torque angle of the bracket based on the malocclusion state information and correction method information, but is not limited to this embodiment.

[0050] Additionally, the device (100) may be implemented as a terminal such as a computer that operates through a computer program to realize the functions described in this specification.

[0051] A device (100) according to one embodiment may include, but is not limited to, a system (not shown) that provides information related to the torque angle of a bracket, a related server (not shown), and an application.

[0052]

[0053] FIG. 2 is a perspective view of a bracket (200) according to one embodiment. As shown in FIG. 2, the bracket (200) according to one embodiment may be configured to include a base portion (210) and a body portion (220).

[0054] The base portion (210) may be formed in a plate shape, and one side, the tooth attachment surface (211), may be attached to the tooth by an adhesive. Additionally, the tooth attachment surface (211) of the base portion (210) may be formed as a curved surface to better adhere to the tooth, but is not limited thereto, and the tooth attachment surface (211) of the base portion (210) may be formed as a flat surface.

[0055] Meanwhile, the body portion (220) is formed to protrude from the other side of the base portion (210) and may be provided with a slot (221) for receiving a wire. Here, the slot (221) may be formed by being recessed in a direction toward the tooth attachment surface (211) of the base portion (210) from the outer surface of the body portion (220) so that the upper side is open.

[0056] Additionally, when a wire is inserted into the slot (221), the body part (220) and the wire are joined together, and the force of the wire is used to apply the force required for orthodontic treatment to the teeth, thereby enabling orthodontic treatment. At this time, the force applied to the teeth or the alignment of the teeth is determined by parameters consisting of torque angle, angulation, rotational offset, and in-out.

[0057]

[0058] FIG. 3 is a side view of FIG. 2 for explaining the torque angle of the bracket. As shown in FIG. 3, the slot (221) can be formed to have a torque angle (α) by being inclined obliquely with respect to the tooth attachment surface (211) of the base portion (210).

[0059] In detail, let v1 be a first vertical axis passing vertically through the center of the mesiocardial axis (X) of the bottom surface of the slot (221), l1 be a tangent to the tooth attachment surface (211) at the intersection point (B1) where the first vertical axis (v1) intersects the tooth attachment surface (211) of the base part (210), and let v2 be a second vertical axis perpendicular to the tangent (l1) at the intersection point (B1). Then, the torque angle (α) is the angle between the first vertical axis (v1) and the second vertical axis (v2).

[0060] That is, if expressed differently, this torque angle (α) can be determined by the angle between the base portion (210) and the slot (221) of the bracket (200).

[0061] In addition, in one embodiment, the torque angle (α) may mean a high torque angle if it is tilted toward the occlusal surface side and a low torque angle if it is tilted toward the gum side, based on a second vertical axis (v2) that is perpendicular to the tangent to the tooth attachment surface (211) of the base part (210).

[0062] In addition, in one embodiment, when a bracket (200) having a high torque angle is attached to the upper jaw, a wire is coupled to the slot (221) after attachment to the tooth, and thus a force is applied to the tooth in a counterclockwise direction because the wire tends to become flat within the slot (221), and when attached to the lower jaw, a clockwise force is applied. Conversely, when a bracket (200) having a low torque angle is attached to the upper jaw, a clockwise force is applied to the tooth, and when attached to the lower jaw, a counterclockwise force is applied.

[0063] This allows the central incisors to be moved according to the purpose of the correction during orthodontic treatment. For example, to prevent excessive inclination of the teeth when moving the upper central incisors, a bracket (200) having a torque angle that applies a force in the opposite direction can be placed. (e.g., using a bracket with a high torque angle when moving the central incisors lingually)

[0064]

[0065] FIGS. 4(a) to 4(c) are perspective views for illustrating a bracket (200) having various torque angles (α) of one embodiment.

[0066] FIG. 4(a) is a drawing showing a high torque bracket having a high torque angle tilted toward the occlusal surface side based on a line (l3) perpendicular to the tangent to the tooth attachment surface (211) of the base part (210); FIG. 4(b) is a drawing showing a low torque bracket having a low torque angle tilted toward the gum side based on a line (l3) perpendicular to the tangent to the tooth attachment surface (211) of the base part (210); and FIG. 4(c) is a drawing showing a bracket having a standard torque angle with no tilting based on a line (l3) perpendicular to the tangent to the tooth attachment surface (211) of the base part (210).

[0067] In one embodiment, the standard torque angle for the maxillary central incisor may be 12°, the high torque angle may be 18°, and the low torque angle may be 7°.

[0068] In addition, in one embodiment, the standard torque angle for the maxillary lateral incisor may be 8°, the high torque angle may be 10°, and the low torque angle may be 3°.

[0069] In addition, in one embodiment, the standard torque angle for the mandibular central incisor may be 0°, the high torque angle may be 6°, and the low torque angle may be -6°.

[0070] The angles disclosed throughout this specification are examples, and a range of angles not disclosed in the specification may also be used.

[0071] FIG. 5 is a flowchart showing each step in which a device (100) according to one embodiment provides information related to the torque angle of a bracket.

[0072] In step S210, the device (100) according to one embodiment can obtain information on the malocclusion state of the teeth, which is determined according to the patient's tooth condition and indicates the positional relationship between the upper jaw and the lower jaw.

[0073]

[0074] In step S220, the device (100) according to one embodiment can obtain orthodontic method information including information on at least one of a central incisor movement method indicating at least one of lingual tipping, bodily movement, and root movement of the central incisor, whether extraction is necessary, and whether a screw is necessary.

[0075] In general, since the position of other teeth is determined based on the position of the central incisors during orthodontic treatment, the method of central incisor movement is a crucial factor. Specifically, tilting movement refers to the central incisor moving so that only the crown tilts without the root moving, while corpuscular movement refers to the movement of both the root and the crown. Additionally, axial movement refers to the central incisor moving so that only the root tilts without the crown moving.

[0076] In addition, tooth extraction may be performed during orthodontic treatment to secure space for tooth alignment. However, extraction may not be necessary if space for tooth alignment already exists within the dental arch or if space can be created by moving the posterior teeth backward.

[0077] Additionally, screws can be inserted by forming holes in the bone of the upper or lower jaw during orthodontic treatment. As screws act as anchors, they may be inserted when moving molars posteriorly to secure space for tooth alignment, when preventing anterior movement of molars, or when inducing root inclination of central incisors when the movement method involves axial displacement.

[0078]

[0079] In step S230, the device (100) according to one embodiment can determine a torque angle determined according to the angle between the base portion of the bracket used for correction and the wire slot based on malocclusion state information and correction method information.

[0080] Additionally, the device (100) according to one embodiment can determine the tooth condition as one of the correct occlusion state, the maxillary protrusion state, and the mandibular protrusion state based on the malocclusion state information, and can determine the torque angle based on the tooth condition.

[0081] In addition, the device (100) according to one embodiment can determine the torque angle as any one of a high torque angle, a standard torque angle, and a low torque angle as described above.

[0082] In addition, the device (100) according to one embodiment can determine the torque angle for the upper jaw as a high torque angle when the tooth condition is determined to be an upper jaw protruding state based on malocclusion state information.

[0083] In addition, the device (100) according to one embodiment can determine the torque angle for the lower jaw as a low torque angle when the tooth condition is determined to be an upper jaw protruding state based on malocclusion state information.

[0084]

[0085] FIG. 6 is a drawing for explaining how a device (100) according to one embodiment determines the torque angles of the upper and lower jaws when the tooth condition is an upper jaw protruding state.

[0086] If the teeth are in a state of maxillary protrusion, orthodontic treatment can be performed by moving the maxilla backward or the mandible forward.

[0087] FIG. 6 (a) is a drawing for explaining how a device (100) according to one embodiment determines a torque angle when the tooth condition is an upper jaw protruding condition and the upper jaw is moved backward.

[0088] For example, if the teeth are in a state of maxillary protrusion and the maxilla is moved backward, the maxillary central incisors are also moved backward. In this case, excessive lingual inclination of the central incisors may occur as a clockwise force is applied to them by the wire.

[0089] Accordingly, the device (100) according to one embodiment can determine the torque angle as a high torque angle to apply a counterclockwise force to the maxillary central incisor to suppress excessive lingual inclination of the maxillary central incisor.

[0090] FIG. 6 (b) is a drawing for explaining how a device (100) according to one embodiment determines a torque angle when the tooth condition is an upper jaw protruding state and the lower jaw is moved forward.

[0091] For example, if the teeth are in a state of maxillary protrusion and the mandible is moved forward, the mandibular central incisors are also moved forward. In this case, a clockwise force is applied to the mandibular central incisors, which can cause excessive labial inclination of the central incisors.

[0092] Accordingly, the device (100) according to one embodiment can determine the torque angle as a low torque angle to apply a clockwise force to the mandibular central incisor to suppress excessive labial inclination of the mandibular central incisor.

[0093] In addition, the device (100) according to one embodiment can determine the torque angle for the upper jaw as a low torque angle and the torque angle for the lower jaw as a high torque angle when the tooth condition is determined to be a mandibular protrusion state according to malocclusion state information.

[0094]

[0095] FIG. 7 is a drawing for explaining how a device (100) according to one embodiment determines the torque angles of the upper and lower jaws when the tooth condition is a lower jaw protruding state.

[0096] If the teeth are in a state of mandibular protrusion, correction can be performed by moving the mandible backward or the mandible forward.

[0097] FIG. 7 (a) is a drawing for explaining how a device (100) according to one embodiment determines a torque angle when the tooth condition is a mandibular protrusion condition and the mandible is moved backward.

[0098] For example, if the teeth are in a state of mandibular protrusion and the mandible is moved backward, the mandibular central incisors are also moved backward. In this case, a counterclockwise force is applied to the mandibular central incisors by the wire, which can cause excessive lingual inclination of the central incisors.

[0099] Accordingly, the device (100) according to one embodiment can determine the torque angle as a high torque angle to apply a clockwise force to the mandibular central incisor to suppress excessive lingual inclination of the mandibular central incisor.

[0100] FIG. 7 (b) is a drawing for explaining how a device (100) according to one embodiment determines a torque angle when the tooth condition is a mandibular protrusion condition and the upper jaw is moved forward.

[0101] For example, if the teeth are in a state of mandibular protrusion and the maxilla is moved forward, the maxillary central incisors are also moved forward. In this case, a counterclockwise force is applied to the maxillary central incisors, which can cause excessive labial inclination of the central incisors.

[0102] Accordingly, the device (100) according to one embodiment can determine the torque angle as a low torque angle to apply a clockwise force to the maxillary central incisor to suppress excessive labial inclination of the maxillary central incisor.

[0103]

[0104] Additionally, the device (100) according to one embodiment can determine the torque angle when a screw is required to be larger than the torque angle when a screw is not required, and can determine the torque angle when tooth extraction is required to be larger than the torque angle when tooth extraction is not required.

[0105] Additionally, the device (100) according to one embodiment can determine the torque angle when the incisor movement method is tooth body movement to be larger than the torque angle when the incisor movement method is inclined movement.

[0106]

[0107] For example, this explains a case where, based on information regarding the orthodontic method for the upper or lower jaw, it is determined that the central incisors must be moved lingually and extractions are necessary to secure space for tooth alignment in order to perform proper orthodontics.

[0108] While inclination movement can be performed solely through crown movement, both the root and crown must be moved to perform body movement; therefore, the force applied to the tooth to perform body movement of the central incisor may be greater than the force applied to the tooth for inclination movement of the central incisor.

[0109] Furthermore, when tooth extraction is performed to secure space for tooth alignment during orthodontic treatment, multiple teeth located in front of the extracted tooth must be moved backward to close the space created; consequently, the force applied to the teeth when extraction is performed can be greater than when extraction is not performed. Additionally, the significant force applied to the teeth to close the extraction space may cause the molars to move forward, which cannot be considered as proper orthodontic treatment. Therefore, to prevent this, the molars can be prevented from moving forward by placing screws in the gums in front of the molars.

[0110] Accordingly, the device (100) of one embodiment can determine a larger torque angle than in the case where, according to the correction method information for the upper or lower jaw, the central incisors are moved lingually and extraction is required to secure tooth alignment space and a screw is required to prevent anterior movement of the molars, when the central incisors are tilted and extraction is not required and a screw is not required. (e.g., determined as a high torque angle rather than a standard torque angle)

[0111]

[0112] In addition, the device (100) according to one embodiment can determine the torque angle when the incisor movement method is tooth body movement to be larger than the torque angle when the incisor movement method is tooth axis movement.

[0113] For example, when performing axial movement of the central incisors for proper orthodontic treatment, this can be done by moving only the roots; however, since both the roots and crowns must be moved to perform body movement, the force applied to the tooth to perform body movement of the central incisors may be greater than the force applied to the tooth for axial movement of the central incisors.

[0114] Accordingly, the device (100) according to one embodiment can determine the torque angle as a standard torque angle when the incisor movement method is tooth axis movement, and determine the torque angle as a high torque angle when the tooth body movement method is tooth body movement.

[0115]

[0116] In step S240, the device (100) according to one embodiment can display information about the determined torque angle.

[0117] For example, information regarding the determined torque angle may be provided on virtual simulation software that simulates the state before and after orthodontic treatment. In one embodiment, “providing” may include an example of a display. For example, a processor (120) included in the device (100) may provide information regarding the torque angle by displaying it. Specifically, the processor (120) may display information regarding the torque angle by controlling the display. Thus, information regarding the determined torque angle may appear on the display.

[0118] FIGS. 8(a) to 8(d) are drawings for explaining the verification of central incisor positional movement for orthodontic treatment through virtual simulation software.

[0119] Referring to Fig. 8(a), the patient's pre-orthodontic oral data can be output to virtual simulation software. The oral data can be obtained in the form of images or video through X-ray imaging, CT (Computed Tomography) imaging, etc.

[0120] Referring to Fig. 8(b), the position of the teeth can be virtually adjusted and output based on the patient's oral data before orthodontic treatment. This has the effect of enabling efficient orthodontic treatment by simulating the ideal position of the teeth after treatment.

[0121] Referring to Fig. 8(c), the virtual simulation software can overlay the oral data before correction and the position of the virtually adjusted tooth to output it in the form of an image or video.

[0122] Referring to Fig. 8(d), the method of moving the central incisor position during correction can be determined based on an overlay image or video output through virtual simulation software.

[0123]

[0124] FIG. 9 is a drawing for explaining that a device (100) according to one embodiment determines whether to extract, the method of moving the incisor, and whether a screw is required according to the determined method of moving the incisor position, and accordingly provides information on the torque angle.

[0125] Referring to FIG. 9, when the malocclusion state is maxillary protrusion and the determined method of movement of the maxillary central incisors is inclined movement, and extraction and screws are unnecessary, the device (100) according to one embodiment for the lingual inclination of the maxillary central incisors can determine the torque angle as a standard torque angle, and the torque angle can be determined as 12°, and information regarding the torque angle can be output through virtual simulation software.
