     FIELD OF THE DISCLOSURE 
     The present disclosure is directed to electromechanical systems, methods, and tools for adjusting orthodontic prescriptions of orthodontic brackets with adjustable archwire passages. 
     BACKGROUND OF THE DISCLOSURE 
     Orthodontic brackets typically are small, slotted devices for use during orthodontic treatment. The brackets usually are configured for attachment to the front surfaces of teeth, either by directly cementing a bracket to a tooth surface or by bonding the bracket to a metal band that encircles the tooth, though in some instances brackets may be attached to the back surfaces of teeth. Slots in the brackets, which may be referred to herein as archwire slots and/or as archwire passages, are disposed horizontally, or generally horizontally, and are configured to receive an archwire. Traditionally, an archwire is a resilient, curved piece of wire that may be bent and/or twisted prior to installation in the bracket slots, with the archwire typically extending through the slots of all of the orthodontic brackets that are attached to a patient&#39;s upper or lower teeth. Engagement between the archwire and the brackets creates corrective, or prescriptive, forces that are directed to the teeth by the orthodontic brackets to urge the teeth into a correct, or desired, alignment, or occlusion. 
     Orthodontic treatment of a patient&#39;s teeth typically requires periodic adjustment of the forces that are imparted to the patient&#39;s teeth by the installed orthodontic brackets, archwire(s), etc. Adjustments include changing the magnitude and/or direction of the forces that are imparted to the patient&#39;s teeth, such as to adjust the degree to which torque, tip, and/or rotational forces are imparted to the patient&#39;s teeth to change the angulation, inclination, rotation, height, and/or location of the teeth in order to move the teeth toward an optimal, or desired, occlusion. 
     As used herein, tipping forces refer to forces applied to the tooth in the mesial-distal direction. Thus, tipping forces may impact angulation. Torsional forces refer to forces applied to the tooth by an archwire that is in torsion within the archwire passage. Thus, torsional forces tend to rotate the tooth in the buccal-lingual or labial-lingual direction and may impact inclination. Rotational forces refer to applied forces that tend to rotate the tooth about its long axis. 
     Adjustment of these forces often is a trial-and-error process that requires removal of the archwire from the archwire slot, bending of the archwire, and re-insertion of the archwire into the archwire slot. Alternatively, the archwire slot may be repositioned. This may include repositioning by removing one or more orthodontic brackets from the patient&#39;s teeth and re-locating (the same or a different) orthodontic bracket on the patient&#39;s teeth. 
     Some orthodontic brackets permit repositioning of the archwire slot without removal of the orthodontic bracket from the patient&#39;s tooth. However, this process still may be time-consuming and/or may require some amount of trial-and-error fitting. Additionally, adjustable brackets may pose challenges for accurately determining a current archwire slot position, such as with respect to a defined treatment plan, and/or the degree to which an adjustment in the archwire slot position accurately reaches a desired position, which also may be defined by a treatment plan. 
     Thus, there exists a need for electromechanical systems, methods, and tools for adjusting orthodontic prescriptions of orthodontic brackets with adjustable archwire passages. 
     SUMMARY OF THE DISCLOSURE 
     Electromechanical systems, methods, orthodontic brackets, and tools for adjusting orthodontic prescriptions of orthodontic brackets with adjustable archwire passages are disclosed herein. The methods include methods of adjusting an orthodontic bracket, which includes an adjustable archwire slot, while the orthodontic bracket is operatively attached to a patient&#39;s tooth. 
     The methods include operatively engaging the orthodontic bracket with an engagement structure of an electronic orthodontic adjustment tool. The methods further include determining a present orientation of the archwire slot relative to a reference orientation at a given point in time. The methods also include displaying a displayed orientation of the archwire slot with the electronic orthodontic adjustment tool. The displayed orientation is based, at least in part, on the present orientation of the archwire slot. The methods further include adjusting the orientation of the archwire slot based, at least in part, on the displayed orientation. 
     The orthodontic brackets include a base configured to be operatively affixed to a tooth that is present within a patient&#39;s mouth. The orthodontic brackets also include a body that is configured to be selectively repositioned relative to the base. The body at least partially defines an archwire slot that is shaped to receive an archwire. The orthodontic brackets further include a retention structure that is configured to be selectively transitioned between a locked configuration and an unlocked configuration. When the retention structure is in the locked configuration, an orientation of the archwire slot relative to a reference orientation is at least substantially fixed. When the retention structure is in the unlocked configuration, the retention structure permits the orientation of the archwire relative to the reference orientation to be varied. The orthodontic brackets further include a transmitter that is configured to generate an orientation indication signal. The orientation indication signal is indicative of the orientation of the archwire slot relative to the reference orientation. The orthodontic brackets also may include an orientation-determining structure that is configured to determine the orientation of the archwire slot relative to the reference orientation. 
     The tools include an electronic orthodontic adjustment tool that is configured to selectively adjust an orientation of an archwire slot, which is defined by an orthodontic bracket, relative to a reference orientation while the orthodontic bracket is operatively attached to a patient&#39;s tooth. The tools include an engagement structure that is configured to operatively engage the orthodontic bracket to selectively adjust the orientation of the archwire slot relative to the reference orientation. The tools further include an orientation indicator that is configured to indicate an orientation of the archwire slot relative to the reference orientation. The tools also may include an orientation-determining structure that is configured to determine the orientation of the archwire slot relative to the reference orientation.

     DETAILED DESCRIPTION AND BEST MODE OF THE DISCLOSURE 
       FIGS. 1-6  provide examples of orthodontic brackets  50  according to the present disclosure, of electronic orthodontic adjustment tools  100  according to the present disclosure, of orthodontic appliance systems  20  that include and/or utilize orthodontic brackets  50  and/or electronic orthodontic adjustment tools  100 , and/or of methods  200 , according to the present disclosure, of adjusting orthodontic brackets. Elements that serve a similar, or at least substantially similar, purpose are labeled with like numbers in each of  FIGS. 1-6 , and these elements may not be discussed in detail herein with reference to each of  FIGS. 1-6 . Similarly, all elements may not be labeled in each of  FIGS. 1-6 , but reference numerals associated therewith may be utilized herein for consistency. Elements, components, and/or features that are discussed herein with reference to one or more of  FIGS. 1-6  may be included in and/or utilized with any of  FIGS. 1-6  without departing from the scope of the present disclosure. 
     In general, elements that are likely to be included in a given (i.e., a particular) embodiment are illustrated in solid lines, while elements that are optional to a given embodiment are illustrated in dashed lines. However, elements that are shown in solid lines are not essential to all embodiments, and an element shown in solid lines may be omitted from a given embodiment without departing from the scope of the present disclosure. 
       FIG. 1  is a schematic representation of examples of an orthodontic bracket  50  having an adjustable archwire passage according to the present disclosure, while  FIG. 2  is a less schematic example of an orthodontic bracket  50  having an adjustable archwire passage according to the present disclosure. Orthodontic bracket  50  also may be referred to herein as a bracket  50  and/or as an adjustable bracket  50 . Bracket  50  includes a base  60 , which is configured to be operatively attached to a tooth  18  that is present within a patient&#39;s mouth  16 . It is within the scope of the present disclosure that bracket  50  may be operatively attached to any suitable surface of tooth  18 , including a front (labial) surface of the tooth and/or a back (lingual) surface of the tooth. This operative attachment often will be directly to the surface of the tooth, although it is within the scope of the disclosure that bracket  50  may be mounted on a band or other intermediate structure that is secured to the patient&#39;s tooth. 
     Bracket  50  also includes a body  70  that at least partially, if not completely, defines an archwire slot  72  that is shaped to receive an archwire  40  during orthodontic treatment of a patient&#39;s teeth. Body  70  additionally or alternatively may be referred to herein as an archwire slot-defining body  70 . Because body  70  contains and/or defines the archwire slot  72  of the bracket, body  70  additionally or alternatively may be referred to herein as a corrective assembly  70 , as the relative orientation of the body with respect to the patient&#39;s tooth to which the bracket is mounted affects the prescriptive forces that are imparted to the tooth during orthodontic treatment. Body  70  may be at least partially, if not completely, housed within base  60 , although it also is within the scope of the present disclosure that at least a portion, or even all, of the body is external base  60 . 
     Body  70  may be configured to be adjusted, or repositioned, relative to the base without detaching the body from the base and/or while the base is operatively attached to tooth  18 . This relative adjustment of the orientation and/or position of the body relative to the base, such as to translate, rotate, and/or pivot the body relative to the base, results in a corresponding adjustment of archwire slot  72  relative to the base, and thereby relative to the patient&#39;s tooth to which the base is attached. Thus, adjustment of the body relative to the base changes the prescription that is defined by the bracket, and thus the forces that are imparted to the patient&#39;s teeth during prescriptive use of the bracket. As used herein, “prescriptive use” and/or “orthodontic use” refer to use of a bracket that is secured to a patient&#39;s tooth and which contains an archwire operatively secured within the bracket&#39;s archwire slot to apply forces to the patient&#39;s tooth to alter the relative orientation of the patient&#39;s tooth in the patient&#39;s mouth. Similarly, “operatively,” when used to describe a relationship between two or more components or elements, refers to the functionality for which the components or elements are designed to be used, assembled, mounted, coupled, etc. 
     The adjustment of body  70  relative to base  60  is enabled by an adjustment mechanism  74  that operatively couples the body to the base and permits selective adjustment of the body relative to the base. The adjustment mechanism may enable, or define, a single axis or plane of adjustment, such as by defining a pivot axis, a rotation axis, a translational plane, etc. of the body relative to the base. However, it also is within the scope of the present disclosure that the adjustment mechanism may enable, or define, more than one degree of relative movement, such as to adjust two or more of the torque, tip, and rotation imparted to the patient&#39;s tooth during prescriptive use of the bracket. As examples, adjustment mechanism  74  may be configured to permit body  70  to rotate relative to base  60  about at least one rotational axis, about at least two rotational axes, or about three distinct rotational axes. As additional examples, adjustment mechanism  74  may be configured to permit body  70  to translate relative to base  60  along at least one translational axis, along at least two translational axes, or along three distinct translational axes. 
     Structurally, adjustment mechanism  74  may define the permitted relative movement of the body relative to the base. The adjustment mechanism may be a separate component that interconnects the base and the body. Alternatively, the adjustment mechanism may form at least a portion of the base and/or the body, such as by having portions of the adjustment mechanism be part of the base and/or the body. Examples of structures and/or mechanisms that may be utilized by adjustment mechanism to provide the relative movement between the base and the body include one or more slides, pivots, races, hinges, ball-and-sockets, dovetail assemblies, springs, elastomers, compliant members, grooves, slides, rails, tracks, channels, sliders, ratchets, axles, wedges, etc. 
     As more specific examples, and as illustrated in  FIG. 2 , body  70  may define a cylindrical or spherical structure, while base  60  may define a cavity  62  that is sized to receive body  70 . When body  70  defines the cylindrical structure, bracket  50  may be configured to selectively permit rotation of body  70  relative to base  60  about a single rotational axis (i.e., a longitudinal axis of the cylindrical structure). When body  70  defines the spherical structure, bracket  60  may be configured to selectively permit rotation of body  70  relative to base  60  about two, or even three orthogonal axes of rotation. 
     Also as illustrated in  FIGS. 1-2 , bracket  50  further may include a retention structure  80  that selectively secures the body in a selected orientation relative to the base (and thus relative to a patient&#39;s tooth to which the bracket is mounted). Retention structure  80  thus may be described as selectively restricting adjustment of the position of the body independent of and/or relative to the base of the bracket. The retention structure may take any suitable form and/or utilize any suitable structure, and the retention structure may be integrated with, cooperate with, and/or function independent of adjustment mechanism  74  without departing from the scope of the present disclosure. 
     Retention structure  80  is configured to be selectively transitioned between a locked configuration and an unlocked configuration. In the locked configuration, retention structure  80  restricts relative movement between the body and the base of the bracket, thereby restricting adjustment of the position of the archwire slot relative to the patient&#39;s tooth to which the bracket is attached. 
     In the unlocked configuration, retention structure  80  permits the body to be moved relative to, or independent of, the base of the bracket. However, when in the unlocked configuration, retention structure  80  still may resist separation of body  70  from base  60 , may operatively interlock body  70  to base  60 , and/or may operatively attach body  70  to base  60 . The locked configuration additionally or alternatively may be referred to as a secured configuration and/or an operative configuration. The unlocked configuration additionally or alternatively may be referred to as an adjustment configuration and/or a released configuration. When the retention structure is in the locked or unlocked configuration, orthodontic bracket  50  additionally or alternatively may be referred to herein as being in the locked or unlocked configuration. 
     Retention structure  80  may include any suitable structure that is configured to transition between the locked configuration and the unlocked configuration, that is configured to selectively maintain the orientation of the archwire slot relative to the base (i.e., when in the locked configuration), that is configured to selectively permit the orientation of the archwire slot to be varied (i.e., when in the unlocked configuration), and/or that is configured to (at least selectively) retain body  70  operatively attached to base  60 . Examples of retention structure  80  include any suitable pin, latch, clasp, wedge, fastener, cam, receptacle, etc. 
     Bracket  50  further may include at least one ligature  52  that is configured to retain archwire  40  within archwire slot  72 . Ligature  52  may include any suitable structure that may, or that may be utilized to, retain the archwire within the archwire slot. This may include any suitable ligating structure that is configured to be operatively attached and/or affixed to base  60  and/or to body  70 , such as an elastomeric band, as well as any suitable ligating structure that forms a portion of bracket  50 , such as when bracket  50  is a self-ligating bracket  50 . 
     Orthodontic bracket  50 , which is schematically illustrated in  FIGS. 1-2 , may have any suitable shape, size, and/or components for receiving an archwire into an archwire slot of the bracket to impart prescriptive forces to a patient&#39;s teeth during orthodontic use of the bracket. As discussed, bracket  50  is an adjustable orthodontic bracket  50 . This may include any suitable orthodontic bracket that is adapted, configured, designed, and/or constructed to permit adjustment of the orientation of archwire slot  72  relative to a reference orientation thereof, relative to base  60 , relative to tooth  18 , relative to another tooth that may be present within patient&#39;s mouth  16 , and/or relative to another orthodontic bracket that may be present within patient&#39;s mouth  16 . Additionally or alternatively, this also may include any suitable orthodontic bracket that may be configured to permit adjustment of the orientation of the archwire slot without separation of the bracket from the tooth. 
     Bracket  50  also may, but is not required to, include additional components, regions, and/or features that are conventional to orthodontic bracket bases/bodies/housings, such as appropriately shaped and/or contoured tooth-contacting surfaces, tie wings, or other suitable mounts for ligating structures, such as ligatures, orthodontic chains, powerchains, springs, elastic bands, and the like. In this regard, examples of orthodontic brackets and bracket assemblies, as well as components and uses thereof, and accessories therefor, are disclosed in U.S. Pat. No. 8,337,198, in U.S. Patent Application Publication Nos. 2012/0308952, 2011/0183280, and 2014/0272751 in U.S. Provisional Patent Application No. 61/913,122, and in U.S. patent application Ser. Nos. 14/559,100 and 14/215,237, the complete disclosures of which are hereby incorporated by reference. These and the subsequently incorporated patent references additionally or alternatively disclose optional additional structures, features, components, and the like that may be used with brackets  50  according to the present disclosure (so long as doing so does not impair the operation and functionality expressly presented herein). 
     Additional examples of ligating orthodontic brackets are disclosed in U.S. Pat. Nos. 6,302,688, 6,582,226, 4,597,739, 4,878,840, 3,772,787, 4,248,588, 4,492,573, 4,614,497, 4,698,017, 1,280,628, 1,821,171, and 3,435,527, the disclosures of which are hereby incorporated by reference. Examples of self-ligating orthodontic brackets are disclosed in U.S. Pat. Nos. 6,659,766, 6,655,957, 6,358,045, 6,193,508, 5,857,850, 5,711,666, 5,562,444, 5,322,435, 5,094,614, 4,559,012, 4,531,911, 4,492,573, 4,419,078, 4,371,337, 4,077,126, 4,144,642, 4,248,588, 4,698,017, 3,772,787, 4,561,844, 4,655,708, 4,197,642, 4,712,999, and 4,171,568, the disclosures of which are hereby incorporated by reference. Still further additional examples of orthodontic brackets are disclosed in U.S. Pat. Nos. 7,819,660, 7,771,640, and 6,632,088, the disclosures of which are hereby incorporated by reference. The structures, features, applications, and methods of the above-identified references may be utilized with and/or incorporated into brackets  50  according to the present disclosure to the extent that doing so does not conflict with the express provisions of the present disclosure. 
     A bracket  50  according to the present disclosure may include (but is not required in all embodiments to include) an orientation-determining structure  90  and/or a transmitter  98 . Orientation-determining structure  90  may be configured to detect and/or otherwise determine the orientation of archwire slot  72 . This may include direct and/or indirect determination of the orientation of the archwire slot. Additionally or alternatively, this also may include determination of an absolute orientation of the archwire slot and/or determination of a relative orientation of the archwire slot, such as relative to a reference orientation thereof. 
     Transmitter  98  may be configured to generate an orientation indication signal  99  that may be indicative of the orientation of the archwire slot relative to the reference orientation, such as may be determined by orientation-determining structure  90 . 
     As discussed in more detail herein, orientation indication signal  99  may be utilized to determine, evaluate, correct, modify, and/or confirm an orthodontic treatment plan for the patient. For example, the orientation indication signal may be utilized to confirm that an archwire slot, or an archwire, is in a selected, or expected, orientation according to an existing treatment plan and/or responsive to a prior orthodontic adjustment. As another example, the orientation indication signal may be utilized to develop an original and/or updated/corrected orthodontic treatment plan for the patient, such as with the orientation indicated by the signal being evaluated, analyzed, compared to stored and/or previously obtained inputs, compared to expected inputs, inputted into prescription-defining software, inputted into orthodontic-bracket/tool/accessory-creating devices, etc. The orientation indication signal from a bracket  50  may be analyzed and/or otherwise utilized independent of the corresponding signals  99  from additional brackets  50  within the patient&#39;s mouth. Additionally or alternatively, the signals  99  from a plurality of brackets  50  may be analyzed or otherwise utilized together and/or concurrently. 
     Orientation-determining structure  90  may include any suitable structure that may be adapted, configured, designed, and/or constructed to determine the orientation of archwire slot  72 , directly and/or indirectly. This may include any structure that may determine the absolute orientation of the archwire slot and/or the orientation of the archwire slot relative to the reference orientation thereof, relative to base  60 , and/or relative to tooth  18 . The orientation of the archwire slot additionally or alternatively may be referred to the position, relative position, rotational position, axial position, translational position, absolute position, etc. An example of an indirect determination includes determining the orientation of the body of the bracket relative to the base or other reference orientation, from which the orientation of the archwire passage is obtained due to the archwire passage extending in a defined, or fixed, orientation within the body. 
     As an example, orientation-determining structure  90  may include and/or be a rotation-determining structure that may be configured to determine a rotation of body  70  relative to base  60  to determine the orientation of archwire slot  72 . This may include determining the rotation of body  70  relative to base  60  about the at least one rotational axis, about the at least two rotational axes, and/or about the three distinct rotational axes. 
     Additionally or alternatively, orientation-determining structure  90  may include and/or be a translation-determining structure that may be configured to determine a translation of body  70  relative to base  60  to determine the orientation of archwire slot  72 . This may include determining the translation of body  70  relative to base  60  along the at least one translational axis, along the at least two translational axes, and/or along the three distinct translational axes. 
     As a more specific example, and as illustrated in  FIG. 2 , orientation-determining structure  90  may include one or more magnets  92  and at least one sensor  94 . Sensor  94  may be configured to detect magnets  92  (or a location thereof and/or a proximity thereto) to determine the orientation of archwire slot  72  relative to the reference orientation. However, this is but a single example, and it is within the scope of the present disclosure that any suitable structure and/or devices may be utilized as, and/or as a part of, the orientation-determining structure  90 . Thus, orientation-determining structure  90  may utilize any suitable sensor, detector, emitter, comparator, mechanism, inductor, capacitor, strain gauge, etc. to determine the orientation of the body relative to the base. 
     Returning more generally to  FIGS. 1-2 , the orientation of archwire slot  72  may be established and/or determined relative to any suitable reference orientation, and the reference orientation may be established and/or defined in any suitable manner. As examples, the reference orientation may be defined relative to base  60 , relative to tooth  18 , relative to a base of another bracket that is present within the patient&#39;s mouth  16 , relative to another tooth that is present within the patient&#39;s mouth, relative to another archwire slot that is defined by the other bracket, and/or relative to a present and/or prior orientation of the archwire slot. 
     As another example, orthodontic bracket  50  may define a home position, and the reference orientation may be defined relative to, or may be, the home position. The home position may be any suitable position of body  70  relative to base  60 . As examples, body  70  may define a range-of-motion relative to base  60 , and the home position may be defined at an extreme of the range-of-motion or as a central point within the range-of-motion. 
     It is within the scope of the present disclosure that bracket  50  may include one or more visual indicators  96  that may visibly indicate when the bracket is in the home position. Examples of visual indicators  96  include any suitable coloration, gradation, line, crosshair, and/or alignment structure that may visually indicate that bracket  50  is (or is not) in the home position. Body  70  optionally may be biased to the home position, such as to automatically be urged toward and/or to the home position when the retention structure is in an unlocked configuration. 
     Bracket  50  additionally or alternatively may include a physical, or tactile, indicator  97  that frictionally urges, or is configured to frictionally urge, the body to stop further adjustment in a given direction when forces are imparted to the body to move the body to, and potentially beyond, the home position. Thus, this increased friction may be felt or otherwise detected to indicate the home position. Any suitable projection, rib, index, detent, surface treatment, etc. may be utilized to provide such a tactile indicator. 
     Transmitter  98  may include any suitable structure that may be configured to generate orientation indication signal  99 . As examples, transmitter  90  may include and/or be a wireless transmitter, a Bluetooth (and/or Bluetooth LE) transmitter, an RFID transmitter, an RFID tag, a digital transmitter, an analog transmitter, an active transmitter, a passive transmitter, a passive transponder, and/or an optical transmitter. The transmitter may transmit any suitable orientation indication signal, including a wireless orientation indication signal and/or a wired orientation indication signal. When the orientation indication signal includes the wired orientation indication signal, transmitter  90  may be configured to directly connect to bracket  50  and/or to transfer the wired orientation signal from the bracket to the electronic device via any suitable electrical and/or communication linkage. 
     As discussed in more detail herein, transmitter  98  may be configured to transmit orientation indication signal  99  to an electronic device that may be utilized with, and/or may form a portion of, an overall orthodontic appliance system  20  that includes bracket  50 . Examples of the electronic device include any suitable computer, laptop computer, desktop computer, tablet, computerized orthodontic machine or system, computing device, handheld electronic device, wearable electronic device, and/or electronic orthodontic adjustment tool. 
     As illustrated in dashed lines in  FIGS. 1-2 , bracket  50  optionally may include a receiver  76  and/or a drive structure  78 . Receiver  76  may be configured to receive an orientation control signal  77 , which also may be referred to herein as a desired orientation signal  77 , from any suitable source. This may include receiving the orientation control signal from another component of orthodontic appliance system  20 , such as the electronic device, as discussed in more detail herein. 
     Regardless of the source of orientation control signal  77 , receiver  76  may be configured to convey the orientation control signal to drive structure  78 . Drive structure  78  then may be configured to selectively regulate, produce, and/or otherwise enable relative motion between body  70  and base  60  such that the orientation of the archwire slot relative to the reference orientation (or the orientation of body  70  relative to base  60 ) is varied. This variation may be based, at least in part, on the orientation control signal. Stated another way, and upon receipt of the orientation control signal, drive structure  78  may be configured to change the orientation of the archwire slot such that the orientation of the archwire slot corresponds to a desired orientation, with the desired orientation being indicated by the orientation control signal. 
     Drive structure  78  may include and/or be in communication with any suitable actuator and/or power source, which may be an electrical power source and/or a battery. The actuator may include an electronic actuator and/or a piezoelectric actuator, as examples. Drive structure  78  optionally may include any suitable motor, gear assembly, piston(s), pump(s), bladder(s), etc. As indicated in dash-dot lines in  FIG. 2 , at least a portion of the drive structure, when present, may be external the bracket and in communication with the bracket when the drive structure is utilized to adjust the orientation of the body. For example, at least a power source, actuator, and/or motor may be selectively connected to the bracket when the drive structure is to be used to adjust the orientation of the archwire slot and/or body relative to the base or other reference location.

As an example, methods  200  may be performed a first time to provide a first, or initial, orientation of the archwire slot of the given orthodontic bracket. Subsequently, the archwire may be utilized to apply one or more prescriptive forces to a given tooth to which the given orthodontic bracket is operatively attached for a first treatment time. Then, methods  200  may be repeated to provide a second orientation of the archwire slot of the given orthodontic bracket. Subsequently, the archwire may be utilized to apply one or more (different) prescriptive forces to the given tooth for a second treatment time. This process may be repeated any suitable number of times until the given tooth has been moved to the desired occlusion. 
     In the present disclosure, several of the illustrative, non-exclusive examples have been discussed and/or presented in the context of flow diagrams, or flow charts, in which the methods are shown and described as a series of blocks, or steps. Unless specifically set forth in the accompanying description, it is within the scope of the present disclosure that the order of the blocks may vary from the illustrated order in the flow diagram, including with two or more of the blocks (or steps) occurring in a different order and/or concurrently. It is also within the scope of the present disclosure that the blocks, or steps, may be implemented as logic, which also may be described as implementing the blocks, or steps, as logics. In some applications, the blocks, or steps, may represent expressions and/or actions to be performed by functionally equivalent circuits or other logic devices. The illustrated blocks may, but are not required to, represent executable instructions that cause a computer, processor, and/or other logic device to respond, to perform an action, to change states, to generate an output or display, and/or to make decisions. 
     As used herein, the term “and/or” placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity. Multiple entities listed with “and/or” should be construed in the same manner, i.e., “one or more” of the entities so conjoined. Other entities may optionally be present other than the entities specifically identified by the “and/or” clause, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” may refer, in one embodiment, to A only (optionally including entities other than B); in another embodiment, to B only (optionally including entities other than A); in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, and the like. 
     As used herein, the phrase “at least one,” in reference to a list of one or more entities should be understood to mean at least one entity selected from any one or more of the entity in the list of entities, but not necessarily including at least one of each and every entity specifically listed within the list of entities and not excluding any combinations of entities in the list of entities. This definition also allows that entities may optionally be present other than the entities specifically identified within the list of entities to which the phrase “at least one” refers, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) may refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including entities other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including entities other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C” and “A, B, and/or C” may mean A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B and C together, and optionally any of the above in combination with at least one other entity. 
     In the event that any patents, patent applications, or other references are incorporated by reference herein and (1) define a term in a manner that is inconsistent with and/or (2) are otherwise inconsistent with, either the non-incorporated portion of the present disclosure or any of the other incorporated references, the non-incorporated portion of the present disclosure shall control, and the term or incorporated disclosure therein shall only control with respect to the reference in which the term is defined and/or the incorporated disclosure was present originally. 
     As used herein the terms “adapted” and “configured” mean that the element, component, or other subject matter is designed and/or intended to perform a given function. Thus, the use of the terms “adapted” and “configured” should not be construed to mean that a given element, component, or other subject matter is simply “capable of” performing a given function but that the element, component, and/or other subject matter is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the function. It is also within the scope of the present disclosure that elements, components, and/or other recited subject matter that is recited as being adapted to perform a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa. 
     As used herein, the phrase, “for example,” the phrase, “as an example,” and/or simply the term “example,” when used with reference to one or more components, features, details, structures, embodiments, and/or methods according to the present disclosure, are intended to convey that the described component, feature, detail, structure, embodiment, and/or method is an illustrative, non-exclusive example of components, features, details, structures, embodiments, and/or methods according to the present disclosure. Thus, the described component, feature, detail, structure, embodiment, and/or method is not intended to be limiting, required, or exclusive/exhaustive; and other components, features, details, structures, embodiments, and/or methods, including structurally and/or functionally similar and/or equivalent components, features, details, structures, embodiments, and/or methods, are also within the scope of the present disclosure. 
     Examples of systems, brackets, tools, and methods according to the present disclosure are presented in the following enumerated paragraphs.
