Technical Field

The disclosed embodiments relate generally to the application of orthodontic brackets, including but not limited to the preparation of bracket applicators for use in installing groups of orthodontic brackets.

Background

The need for orthodontics to diagnose, prevent and/or correct misaligned teeth and jaws continues to increase. One of the primary methods of correcting misaligned teeth and jaws is to apply orthodontic brackets (sometimes also referred to as braces) to a patient's teeth. Each orthodontic bracket is affixed to a tooth and the wires and/or bands connecting the brackets are used to realign the patient's teeth and/or jaw.

Orthodontic brackets are typically mass produced and include some preset design options. These prefabricated orthodontic brackets are not designed to precisely fit individual teeth of a patient, nor are they designed to correct a particular malposition of a patient. Accordingly, an orthodontist will typically examine a patient's teeth and select a preset design option that most closely fits the patient's teeth or best suits the corrective mechanism that the orthodontist wishes to apply. However, the use of non-personalized orthodontic brackets can lead to non-optimal results, i.e., individual teeth cannot be precisely realigned. For example, for non-personalized orthodontic brackets, the amount of force applied to a particular tooth may not be sufficient to properly realign the tooth, resulting in delay or failure; or unnecessarily high, causing unnecessary pain to the patient and possibly damaging the teeth.

In addition, non-personalized orthodontic brackets are difficult to attach to teeth with the precise and precise positioning required to optimize the correction of misaligned teeth and jawbone. In addition, non-personalized orthodontic brackets may also detach from the teeth because they are not precisely attached.

Detailed Description

Reference will now be made in detail to embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of various described embodiments. It will be apparent, however, to one skilled in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedures, components, and devices have not been described in detail as not to unnecessarily obscure aspects of the embodiments.

Fig. 1A-1C show perspective views of bracket mounts according to some embodiments. FIG. 1A shows a side view and a front view of a bracket 102 attached to a tooth 100. Fig. 1A also shows a bracket mount 104 and a bonding material 106 for attaching the bracket 102 to the tooth, the bracket mount 104 being configured to apply the bracket 102 to the tooth 100. The bracket mount 104 is configured to optimize the positioning of the bracket 102 on the tooth 100. For example, the bracket mount 104 is configured to optimize the attachment angle between the tooth 100 and the bracket 102. In some embodiments, the attachment angle is maintained by filling the gap between the bracket 102 and the tooth 100 with the bonding material 106. In some embodiments, the bracket mount 104 is prepared based on a mapping (e.g., a three-dimensional mapping) of the patient's teeth. In some embodiments, optimizing the positioning of the bracket 102 on the tooth includes optimizing the relationship between the bracket 102 and a bracket wire configured to couple the bracket 102 to other brackets on the patient's tooth. In some embodiments, the relationship between the bracket 102 and the bracket wire is optimized such that the force applied to the tooth by the bracket 102 and the bracket wire displaces the tooth in a desired direction. In some embodiments, the relationship between the bracket 102 and the bracket wire is optimized such that the force applied to the bracket 102 from the bracket wire is more evenly distributed across the bracket 102. In some embodiments, the bracket mount 104 is configured to suspend the bracket 102 in an optimal position relative to the tooth 100 while the bracket 102 is affixed to the tooth 100 with a bonding material. In some embodiments, the inner surface of the bracket mount is configured such that it is the reverse of the bracket surface for anterior-posterior mating. In some embodiments, the bracket mount 104 is configured with a vertical slot, a horizontal slot, or both for vertical and lateral mating. In some embodiments, the bracket mount 104 includes a pair of parallel surfaces that are perpendicular to the tooth surface and are at 90 degrees to the vertical or horizontal slot. In some embodiments, the bracket mount 104 includes an undercut to facilitate separation of the bracket mount from the bracket 102 after the bracket has been mounted to the tooth 100.

FIG. 1B shows a side view of the bracket 102 attached to the tooth 100 with a bonding material 106. Fig. 1B also shows a bracket mount 110 configured to selectively couple to the bracket 102 and apply the bracket 102 to the tooth 100. The bracket mount 110 differs from the bracket mount 104 of FIG. 1A in that it includes an undercut 108, an undercut 108-1 on the top of the bracket mount 110, and an undercut 108-2 on the bottom of the bracket mount 110. In some embodiments, the bracket mount 110 includes a single undercut 108 (e.g., only undercut 108-1 or only undercut 108-2). In some cases, the undercut 108 facilitates removal of excess bonding material 106 and, in some embodiments and circumstances, reduces the likelihood of the bracket mount 110 attaching to the tooth 100 via the bonding material 106. In some cases, the undercut 108 facilitates separation of the bracket mount 110 from the bracket 102 after the bracket has been mounted to the tooth 100.

FIG. 1C shows a side view and a front view of a bracket 102 attached to a tooth 100 with a bonding material 106. Fig. 1C also shows a bracket mount 112 configured to selectively couple to the bracket 102 and apply the bracket 102 to the tooth 100. The bracket mount 112 differs from the bracket mount 104 of fig. 1A in that the bracket mount 112 includes an exit port 110 that facilitates removal of excess bonding material 106, and has a positive release angle at the top of the mount. The positive release angle at the top of the bracket mount 112 reduces the likelihood of the bracket mount 112 attaching to the tooth 100 through the bonding material 106. In some embodiments, the positive release angle minimizes bonding of the bracket mount to the tooth by the bonding material 106 (e.g., excess bonding material). In some embodiments, the bracket mount 112 includes the exit port 110, but does not have a positive release angle. In some embodiments, the bracket mount 112 has a positive release angle, but does not include the exit port 110. In some embodiments, the bracket mount 112 is configured to control the flow of the bonding material 106 (e.g., excess bonding material 106) during cementing of the bracket 102 to the tooth 100. In some embodiments, the exit ports 110 are configured to control the flow of the bonding material 106 (e.g., excess bonding material 106) during cementing of the bracket 102 to the tooth 100. In some embodiments, the vents 110 are configured to enable excess bonding material 106 to escape from the bonding area to prevent misalignment of the bracket 102 or weakening of the bond between the bracket 102 and the tooth during and/or after the bonding process. In some embodiments, the exhaust port 110 is located on the occlusal side of the bracket mount. In some embodiments, the exit port 110 is located on the gingival side of the bracket mount. In some embodiments, the vent 110 is positioned away from the mass of bonding material 106.

Fig. 1D illustrates a perspective view of a bracket mount and bracket mount removal tool, according to some embodiments. Fig. 1D shows front, bottom, and side views of the bracket 102 attached to the tooth 100 with a bonding material 106. FIG. 1D also shows a bracket mount 114 coupled to the bracket 102 and a bracket mount removal tool 116 (also sometimes referred to as a bracket mount decoupling tool). The bracket mount removal tool 116 is configured to decouple the bracket mount 114 from the bracket 102 while minimizing the possibility of the bracket 102 becoming dislodged from the tooth 100. The bracket mount removal tool 116 is configured to slide between the bracket mount 114 and the bracket 102. The twisting motion applied to the bracket mount tool 116 results in a force that separates the bracket mount 114 from the bracket 102 without separating the bracket 102 from the tooth 100. In some embodiments, the bracket mount 114 and/or bracket mount tool 116 is configured to release the bracket mount from the bracket 102 while minimizing the risk of bracket dislodgement from the tooth (e.g., by minimizing the force pulling the bracket 102 away from the tooth 100). In some embodiments, the bracket mount 114 and/or bracket mount tool 116 is configured to release the bracket mount from the bracket 102 while minimizing weakening of the bonding material 106 (e.g., by minimizing the force pulling the bracket 102 away from the bonding material 106). In some embodiments, the bracket mount includes a relief slot configured to allow the bracket mount tool to access a space between the bracket mount and the bracket. In some embodiments, the bracket mount tool is configured to apply a rotational force that simultaneously pushes the bracket toward the tooth and pushes the bracket mount away from the bracket.

Fig. 2A-2H illustrate perspective views of a dental mount according to some embodiments. FIG. 2A shows front and side views of a bracket 102 positioned on a tooth 100. Fig. 2A also shows the bracket 102 positioned via the bracket mount 104 and the tooth mount 202. The tooth mount 202 is configured to align and stabilize the bracket 102 on the tooth 100. For example, the bracket mount 104 is configured to optimize the attachment angle between the tooth 100 and the bracket 102, and the tooth mount 202 is configured to attach the bracket 102 at an optimal location on the tooth 100. In some embodiments, the bracket mount 104 and the tooth mount 202 constitute a single mount (e.g., connected together such that they are indistinguishable from one another). In some embodiments, the tooth mount 202 includes a plurality of stops 204 (e.g., stops 204-1, 204-2, and 204-3 in fig. 2A) for coupling to the teeth. For example, the stop (e.g., stop 204-1) is configured to precisely fit a particular location on the tooth 100. In some embodiments, the bracket mount 104 is configured to position the bracket 102 in a particular orientation on the tooth 100. In some embodiments, the tooth mount 202 is configured to position the bracket 102 at a particular location on the tooth 100. In some embodiments, the dental mount 202 includes a plurality of stops 204 connected by a plurality of connectors. In some embodiments, the dental mounts 202 are prepared based on a mapping of the patient's teeth (e.g., the dental mounts are 3D printed). In some embodiments, the bracket mount 104 and the tooth mount 202 are made from a single piece of plastic (e.g., using a 3D printer).

In some embodiments, the tooth mount 202 is configured to use one or more tooth surfaces as reference points for positioning the bracket 102 on a tooth. In some embodiments, the dental mount includes one or more incisor stops (e.g., stops 204-1 and 204-2). In some embodiments, the dental mount includes a plurality of incisor stops to improve stability. In some embodiments, the dental mount includes a bracket or a dental identifier, such as a chiseled corner. For example, the stop 204-1 in FIG. 2A includes a chiseled corner as the bracket identifier. In some embodiments, the tooth mount 202 is configured to use the incisal edges of the teeth as a vertical stop. In some embodiments, one or more of the stops (e.g., stop 204-1) comprise an undercut (e.g., an undercut configured to couple to a cutting edge) coupled to the tooth. In some embodiments, the undercut is configured to be minimized so as to substantially match the insertion path and the removal path of the dental mount 202. In some embodiments, the dental mount is configured such that the insertion path and the removal path are substantially vertical relative to the face of the tooth. In some embodiments, the tooth mount includes an incisor stop and an occlusal stop different from the incisor stop (e.g., to facilitate cleaning of the bracket and/or bracket base).

FIG. 2B shows a front view of a patient's teeth 100 with the bracket mount 104 and the tooth mount 202 coupled to each tooth 100 (e.g., bracket mount 104-1 and tooth mount 202-1 coupled to tooth 100-1). Fig. 2B also shows a connector 206 interconnecting the dental mounts 202. For example, the connector 206-1 connects the dental mount 202-1 to the dental mount 202-2. In some embodiments, the connector 206 is configured based on the relative positioning of the teeth 100. For example, the connector 206-1 is configured to optimize the positioning of the dental mount 202-1 on the tooth 100-1 and the positioning of the dental mount 202-2 on the tooth 100-2. In some embodiments, the connector 206 has a width that is based on the amount of force applied to the adjacent teeth (e.g., the greater the amount of force, the wider the connector 206). For example, FIG. 2B shows connector 206-2 having a wider profile than connector 206-1. In some embodiments, the connector is configured to couple a plurality of dental mounts for arch or segmented cementing. In some embodiments, the connector is configured to provide rigidity to hold the dental mounts together in precise positioning. In some embodiments, the connector 206 has different thicknesses to provide flexibility for engaging the back undercut.

Fig. 2C shows front, bottom, and side views of the bracket 102 attached to the tooth 100 with the bonding material 106. Fig. 2C also shows a mount 208 configured to position the bracket 102 at an optimal position and/or angle on the tooth 100. In some embodiments, the mount 208 comprises a bracket mount.

Fig. 2D also shows a mount 208 configured to position the bracket 102 at an optimal position and/or angle on the tooth 100. For example, the mounting member 208-1 positions the bracket 102-1 on the tooth 100-1, and the mounting member 208-2 positions the bracket 102-2 on the tooth 100-2. Fig. 2D also shows a connector 207 connecting the mounts 208 to each other. For example, connector 207-1 connects mounting member 208-1 to mounting member 208-2. According to some embodiments, the connector 207 is configured to position the bracket 102 in an optimal position on the tooth 100. The connector 207 optionally includes a stop 205 for aligning the bracket 102 with the tooth 100. For example, the connector 207-1 includes stops 205-1 and 205-2. The stop 205-1 is configured to align and stabilize the mount 208-1 on the tooth 100-1, and the stop 205-2 is configured to align and stabilize the mount 208-2 (in combination with the stop 205-3) on the tooth 100-2. As shown in the side view of fig. 2D, in some embodiments, the connector 207 is configured to couple to the front, back, and bottom portions of the teeth. In some embodiments, the connector 207 is configured to couple to the front and bottom portions of the teeth, but not to the rear portion. In some embodiments, the stop 205 is configured to provide a visual fit check for the mount 208. In some embodiments, as shown in the side view, the connector 207 is configured to couple to the buccal and lingual undercuts of the patient (e.g., to provide stability and positioning of the mount 208).

FIG. 2J shows side, front, and bottom views of the bracket 102 positioned on the tooth 100. Fig. 2J also illustrates a representative tooth mount 232 configured to contact the occlusal tip and/or marginal crest of the tooth 100 (e.g., to provide stability and minimize wobble).

Fig. 3A-3B illustrate perspective views of a bracket applicator, according to some embodiments. FIG. 3A shows brackets 308 positioned over a set of teeth. Fig. 3A also shows a mount 306 (e.g., mount 208, fig. 2C) coupled to a bracket 308 (e.g., bracket 102, fig. 1A) and a connector 304 (e.g., connector 207, fig. 2D) coupling mounts 306 to one another. Fig. 3A also shows an applicator 300 for applying brackets 308 to a patient's teeth. As shown in fig. 3A, applicator 300 includes a handle 302. The handle 302 is configured such that squeezing the handle results in less force being applied to the teeth by the applicator 300, and releasing the handle results in more force being applied to the teeth by the applicator 300. In some embodiments, applicator 300 is removably coupled to mount 306 and connector 304. In some embodiments, applicator 300 is fixedly coupled to mount 306 and connector 304. In some embodiments, applicator 300 is configured to simultaneously apply a plurality of brackets 308 to respective teeth for arch or segmental cementing. In some embodiments, applicator 300 is configured to provide rigidity to keep all mounts 306 in precise positioning.

In some embodiments, applicator 300 is configured to provide self-positioning and/or self-retention of bracket placement (e.g., during bracket cementing to a tooth). In some embodiments, applicator 300 has different thicknesses along its length (e.g., to provide flexibility for engaging the posterior undercut). In some embodiments, applicator 300 includes a relatively thin front connector (e.g., to increase flexibility). In some embodiments, applicator 300 includes a relatively thick and/or rigid rear connector (e.g., to prevent buckling along the length of the applicator). In some embodiments, applicator 300 includes a handle 302 to facilitate placement of applicator 300 in a patient's mouth and alignment of brackets. In some embodiments, the handle 302 includes a squeeze handle for opening back displacement (e.g., to engage and disengage the back undercut). In some embodiments, the handle 302 includes a crush block 303, the crush block 303 configured to limit the crush distance (e.g., to prevent the connector 304 from breaking). In some embodiments, the crush block 303 is configured to limit the crush distance sufficiently to engage/disengage the back undercut without risk of breaking the connector 304. In some embodiments, the handle 302 includes a self-locking feature (e.g., using the expression nubs 303) to lock the handle in the expressed position to facilitate placement of the applicator in the patient's mouth.

In some embodiments, applicator 300 is configured to facilitate positioning of orthodontic brackets on a patient's teeth. For example, applicator 300 is configured to fit a particular location on a particular tooth to ensure proper placement. In some embodiments, the applicator 300 is configured to facilitate positioning and installation of a single orthodontic bracket. For example, previously placed brackets have been displaced, and the applicator 300 is configured to replace only the displaced brackets. In some embodiments, applicator 300 is prepared based on a mapping of the patient's teeth (e.g., the applicator is 3D printed).

Similar to fig. 3A, fig. 3B shows brackets 308 positioned on the set of teeth 301. FIG. 3B also shows mount 306 coupled to bracket 308 and connector 304 coupling mounts 306 to each other. Fig. 3B also shows an applicator 300 for applying brackets 308 to a patient's teeth. As shown in fig. 3B, in some embodiments, applicator 300 does not include a bracket 308 or bracket mount 306 for each tooth in the patient's set of teeth. For example, applicator 300 includes mounting 306-1 and bracket 308-1 for tooth 301-1, but does not include a mounting or bracket for tooth 301-3. According to some embodiments, applicator 300 is configured to apply brackets 308 on only a portion of a patient's teeth based on the type of orthodontic treatment desired or selected by the patient. In some cases, misalignment of the patient's teeth and/or treatment planning of the patient requires that brackets be applied to only a portion of the patient's teeth. According to some embodiments, applicator 300 is configured to apply brackets to only a portion of a patient's teeth.

FIG. 3C shows brackets 312 positioned over a set of teeth. FIG. 3C also shows the mounts 310 coupled to the brackets 312 and the connectors 314 coupling the mounts 310 to one another. Fig. 3C also shows a snap connection rod configured to increase the stability of the mount 310 and to facilitate accurate positioning of the bracket 312 on the tooth. In some embodiments, the bite connection rod is configured to act as a finger stop (e.g., to enable the finger to apply pressure and stability) during bracket cementing to the tooth. In some embodiments, the shape and/or thickness of the occlusal connecting bar is based on the positioning of the patient's teeth and/or the requirements of the patient's orthodontic treatment. FIG. 3C also shows a distance denoted "d" illustrating the displacement for engaging the undercut.

Fig. 4 is a flow diagram illustrating a representative method 400 for attaching orthodontic brackets to a patient's teeth, according to some embodiments.

For each tooth in the set of patient teeth, an optimal orientation of a respective orthodontic bracket to be mounted on the tooth is determined (402). In some embodiments, a 3D model of the patient's teeth is generated (404). In some embodiments, the optimal orientation is determined based on a 3D model or map of the patient's teeth. In some embodiments, an optimal axis inclination, torque, and/or rotation for each orthodontic bracket is determined (406). In some embodiments, determining the optimal orientation includes determining an optimal shaft inclination, torque, and/or rotation for each bracket.

A bracket applicator is prepared (408). Such as applicator 300 shown in fig. 3A. The bracket applicator is configured to mount each orthodontic bracket (e.g., bracket 102, fig. 1A) to a respective tooth of the set of teeth in a respective optimal orientation. In some embodiments, the bracket applicator includes (410) a plurality of tooth mounts (e.g., tooth mount 202, fig. 2B) and a connector (e.g., connector 206, fig. 2B) coupling the plurality of tooth mounts to one another, wherein each tooth mount is personalized for a respective tooth of the patient. In some embodiments, the bracket applicator is made of plastic, polymer, or similar material. In some embodiments, the bracket applicator is prepared by 3D printing. In some embodiments, preparing the bracket applicator includes generating a computer model of the bracket applicator based on the patient's prescription. In some embodiments, preparing the bracket applicator includes generating a computer model of the bracket applicator based on measurements of the patient's teeth (e.g., based on a mold of the patient's teeth). In some embodiments, preparing the bracket applicator comprises printing a computer model of the bracket applicator through a 3D printer.

The set of orthodontic brackets is mounted (412) to the set of teeth using a bracket applicator (e.g., applicator 300, fig. 3A) and a bonding material (e.g., resin). For example, FIG. 1A shows a bracket 102 mounted to a tooth 100 by a bonding material 106.

Fig. 5A-5C show perspective views of representative brackets, according to some embodiments. FIG. 5A illustrates a bracket 504 coupled to a base 502 by a coupling 506, according to some embodiments. In some embodiments, the brackets 504 comprise pre-fabricated brackets that are independent of the prescription of the individual patient. In some embodiments, coupling 506 comprises a welded coupling (e.g., a laser welded coupling). In some embodiments, the base 502 comprises a custom base prepared according to a patient's prescription. In some embodiments, the length and/or width of the base 502 is based on the shape of the corresponding teeth of the patient. In some embodiments, the length and/or width of the base 502 is based on the alignment between the corresponding tooth and the adjacent tooth of the patient. In some embodiments, the length and/or width of the base 502 is based on the desired correction to the patient. In some embodiments, the bracket 504 is configured to be coupled to the base 502 prior to attachment of the base to the patient's tooth. In some embodiments, the bracket 504 is configured to be coupled to the base 502 prior to attachment of the base to the patient's tooth.

In some embodiments, the base 502 is prepared by 3D printing. In some embodiments, preparing the base 502 includes generating a computer model of the base based on the patient's prescription. In some embodiments, preparing the base 502 includes generating a computer model of the base based on measurements of the patient's teeth (e.g., based on a mold of the patient's teeth). In some embodiments, preparing the base 502 includes printing a computer model of the base through a 3D printer.

In some embodiments, the base 502 is constructed of a material different from the material of the bracket 504. In some embodiments, the base 502 comprises a resin, plastic, polymer, or the like. In some embodiments, the base 502 comprises a metal base. In some embodiments, the bracket 504 is constructed of metal, plastic, polymer, or the like.

FIG. 5B illustrates a bracket 512 coupled to a base 510 by a coupling 514, according to some embodiments. In some embodiments, the brackets 512 comprise pre-fabricated brackets that are independent of the prescription of the individual patient. In some embodiments, base 510 comprises a custom base prepared according to a patient's prescription. In the example of FIG. 5B, bracket 512 includes a notch 513 and base 510 includes a corresponding protrusion 511 for aligning and/or attaching bracket 512 to base 510. In some embodiments, bracket 512 is attached to base 514 by a mechanical lock. In some embodiments, coupling 514 includes a mechanical coupling (e.g., using notch 513 and protrusion 511) and/or a welded coupling (e.g., a laser welded coupling).

FIG. 5C illustrates a bracket 522 coupled to a base 520 by a coupling 524, according to some embodiments. In some embodiments, the brackets 522 comprise pre-fabricated brackets that are independent of the prescription of the individual patient. In some embodiments, base 520 comprises a custom base prepared according to a patient's prescription. In the example of fig. 5C, the bracket 522 includes a cavity and the base 520 includes a corresponding protrusion 521 for aligning and/or attaching the bracket 522 to the base 520. In some embodiments, the bracket 522 is attached to the base 524 by a mechanical lock.

In some embodiments, the protrusion 521 comprises a material different from the material of the base 520. In some embodiments, the protrusion 521 is used to align the bracket 522 with the base 520.

6A-6C illustrate perspective views of representative brackets, according to some embodiments. FIG. 6A shows a bracket 602. In some embodiments, the brackets 602 comprise custom brackets prepared according to a patient's prescription. In some embodiments, the length and/or width of the base portion of the bracket 602 is based on the shape of the corresponding tooth of the patient. In some embodiments, the length and/or width of the base portion of the bracket 602 is based on the alignment between the corresponding tooth and the adjacent tooth of the patient. In some embodiments, the length and/or width of the base portion of the bracket 602 is based on the desired correction of the patient.

In some embodiments, the bracket 602 is prepared by 3D printing. In some embodiments, preparing the brackets 602 includes generating a computer model of the brackets based on the patient's prescription. In some embodiments, preparing the brackets 602 includes generating a computer model of the brackets based on measurements of the patient's teeth (e.g., based on a mold of the patient's teeth). In some embodiments, preparing the brackets 602 includes printing a computer model of the brackets by a 3D printer.

FIG. 6B shows brackets 621, 623, and 625 for a guidewire slot, the brackets 621, 623, and 625 having different widths 622, 624, and 626, respectively. The fit between the guide wire (also sometimes referred to as an "archwire") and the guide wire slot affects the extent to which torque 620 is lost. For example, bracket 621 has a large width 622, and therefore loses more torque than bracket 623 or bracket 625. In some embodiments, the sizing of the guide wire slot (e.g., the width of the slot) is based on the patient's prescription (e.g., based on what the optimal torque for a particular tooth is). In some embodiments, the sizing of the guidewire slot is based on the size and/or shape of the guidewire (e.g., gauge of wire). In some embodiments, the width of the guidewire slot ranges from 0.019 inches to 0.022 inches. In some examples and embodiments, an offset angle of 9 degrees between the guidewire and the bracket corresponds to a baseline torque on the bracket, an offset angle of 17 degrees corresponds to a 10% reduction in torque, and an offset angle of 23 degrees corresponds to a 20% reduction in torque.

FIG. 6C shows a bracket 630 having two members 630-1 and 630-2, according to some embodiments. In some embodiments, the components 630-1 and 630-2 of the bracket 630 are coupled so as to optimize the width of the guidewire slot of the bracket 630. For example, the components 630-1 and 630-2 are positioned such that a particular width is created for the guidewire slot, where the particular width is based on the sizing of the guidewire and/or the patient's prescription. In some embodiments, the two components are coupled by a bonding material (e.g., a resin). In some embodiments, the two components are coupled by welding (e.g., laser welding). In some embodiments, the two components 630-1 and 630-2 are positioned to optimize the width of the guidewire slot and then coupled (e.g., by an adhesive material or welding).

7A-7E illustrate perspective views of representative brackets, according to some embodiments. FIG. 7A shows brackets 702, 704, 706, and 708 having different sized bases (e.g., bracket 702 has the largest base and bracket 708 has the smallest base). In some embodiments, the base size of the bracket is based on the patient's tooth size and/or prescription. The larger base size enhances the bond between the bracket and the tooth to prevent bracket migration. The smaller base size increases aesthetics and minimizes the orthodontic footprint of the patient. In some embodiments, preparing brackets having base dimensions based on the patient's teeth and/or prescription includes generating a computer model of the brackets based on the mapping of the patient's teeth. In some embodiments, preparing the brackets includes printing a computer model of the brackets by a 3D printer.

Fig. 7B shows a mismatch between a preformed bracket and a patient's tooth. FIG. 7B illustrates a first misalignment at 711 and a second misalignment at 713 (e.g., because the bracket was not manufactured according to the patient's tooth and/or prescription). Due to misalignment, the bracket in FIG. 7B is more easily displaced (e.g., compared to the bracket in FIG. 7C). FIG. 7B also shows the bracket immediately adjacent the patient's gum at 715. The close proximity of the brackets may cause more inflammation and discomfort to the patient. The close proximity of the brackets may also make cleaning of the teeth, brackets, and/or gums more difficult.

Fig. 7C shows how the problem in fig. 7B can be alleviated by using custom brackets (e.g., based on the particular teeth of the patient). In areas 717 and 719, the custom bracket fits more closely to the patient's tooth (e.g., as compared to the bracket in FIG. 7B), enhancing the bond between the bracket and the tooth, and reducing the likelihood of the bracket becoming dislodged during use. In region 721, there is greater spacing between the brackets and the patient's gums (e.g., as compared to the brackets in FIG. 7B), reducing the likelihood of inflammation and discomfort to the patient. In some embodiments, custom brackets are prepared based on the shape of the patient's teeth and/or the patient's prescription in order to optimize the bond between the bracket and the teeth and minimize patient discomfort.

Fig. 7D shows a preformed bracket 710 bonded to a patient's tooth. The bracket 710 in FIG. 7D is manufactured independently of the patient's teeth. In contrast, bracket 712 in FIG. 7E is prepared based on the size and/or shape of the patient's tooth. According to some embodiments, the brackets 712 are prepared to optimize the spacing between the brackets and the patient's gums. According to some embodiments, the sizing of the brackets 712 is also optimized based on the patient's prescription (e.g., based on the amount of force and/or torque to be applied to align the patient's teeth).

8A-8C illustrate perspective views of representative brackets, according to some embodiments. FIG. 8A shows brackets 802, 804, 806, 808, and 810 having different wing sizes. For example, bracket 802 has the largest wing size, bracket 808 has the smallest wing size, and bracket 810 has no wings. In some embodiments, the wing dimensions of the bracket are optimized for a particular patient (e.g., based on the patient's prescription). According to some embodiments, the wing size of the bracket is minimized to increase patient comfort (e.g., minimize the patient's chance of ulceration), improve oral hygiene (e.g., by minimizing food retention and facilitating cleaning of the bracket and/or teeth), and/or improve aesthetics. In some embodiments, the bracket wings are used to attach an elastic band to couple the bracket to another bracket in the patient's mouth. In some embodiments, the brackets are prepared with bracket wings, depending on the determination of the elastic band that the patient's prescription requires to be attached to the brackets. In some embodiments, the brackets are prepared without bracket wings, depending on the determination that the patient's prescription does not require attachment of an elastic band to the brackets.

In some embodiments, the bracket wing parameters (e.g., angle, size, shape, etc.) are based at least in part on the patient's bite. For example, the custom bracket 812 in FIG. 8C is prepared to avoid interfering with the patient's bite and/or to minimize bracket displacement due to the patient's bite. In contrast, the pre-fabricated brackets 814 in FIG. 8B interfere with the patient's bite.

Fig. 9A-9C illustrate representative brackets customized to the preferences of a patient. For example, FIG. 9A shows a bracket 902 with gold plating. In some embodiments, the patient is able to select a plating or coating of the bracket. For example, the patient may select from a list of color options, including one or more patterns and/or one or more images. In some embodiments, the brackets are prepared from custom coatings or platings received from a patient or generated from input from a patient. FIG. 9B shows bracket 904 having a star shape, and FIG. 9C shows bracket 906 having a heart shape. In some embodiments, the star shape is one of a list of shape options for selection by the patient. For example, the patient selects from a defined shape such as a heart, star, diamond, etc. In some embodiments, the bracket is prepared with a custom shape generated according to patient preferences. In some embodiments, the patient is able to select one or more accessories for the bracket, such as diamonds or crystals. In some embodiments, the selected accessory is attached to the bracket.

In some embodiments, the brackets are prepared according to the patient's prescription and according to one or more aesthetic preferences of the patient. In some embodiments, preparing the bracket according to one or more aesthetic preferences of the patient includes: (1) displaying a list of aesthetic design options to the patient; and (2) receiving a selection of one or more aesthetic options from the patient. In some embodiments, the displayed list of aesthetic design options is based at least in part on the patient's prescription. For example, the displayed list of aesthetic design options includes only the aesthetic design options for brackets having large tray wings, as determined by the patient's prescription requiring brackets to have large tray wings (e.g., bracket 802 in fig. 8A).

In some embodiments, the bracket is constructed of a particular material selected based on the patient's prescription and/or the patient's aesthetic preferences. For example, the brackets may optionally be made of a harder alloy or a softer alloy, depending on the patient's prescription. As another example, the bracket may be constructed of gold or platinum alloy, depending on the aesthetic preference of the patient.
