The vector may be determined by comparing the digital model of the pre-treatment geometry of the patient's teeth including the initial tooth position to the digital orthodontic model of the patient's teeth including the ideal tooth position. May be for each individual tooth to be in its initial position (x)_i) And its final position (x)_f) The force vector may be determined to reposition the tooth from its initial position to its final position using the distance of travel (the length of the vector) and information about the resistance of the tooth (e.g., the resistance of the tissue and the frictional force of the tooth surfaces rubbing against each other), the tissue (e.g., the health of the gums), the mandibular anatomy, and/or other patient factors (e.g., age, gender, etc.).

As shown in fig. 3 (as described elsewhere herein), the archwire may be bent between the brackets to form an interproximal curvature 302 that may be biased to expand outward or retract inward, thereby applying a force to the brackets 300 on adjacent teeth, the interproximal curvature 302 may be configured to rotate more teeth, the archwire 303 may be twisted about its axis to provide a torsional force to the adjacent bracket or brackets 300, it may be desirable to use a non-sliding mechanics (where the archwire 303 is fixedly secured to each bracket 300 and does not slide relative to the brackets 300) to provide a customized individualized force to each tooth using the archwire 303. the archwire 303 may comprise a shape memory alloy (e.g., nitinol) the shape memory archwire 303 may be formulated with a pre-deformed shape that, when applied to a desired tooth position, does not result in movement of the tooth.

In some embodiments , after applying orthodontic treatment (such as with an archwire including an interproximal curve 302), the observed or measured actual displacement may be used to generate feedback that may improve modeling of subsequent archwires and more than force vectors as may be obtained by three-dimensional intraoral scanning, impression, or any other suitable method including those discussed elsewhere herein fig. 4 schematically shows a three-dimensional model showing superimposed positions of individual teeth before and after orthodontic treatment (i.e., tooth movement). the original position of a tooth is indicated as X, Y and Z (829, θ, Φ) in three-dimensional coordinate space (XYZ, coordinate grid) as may be found 632 and Z (829, θ, Φ) after treatment/movement with the position of a tooth as may be found by X ', Y ' and Z ' after treatment/movement.7323. the displacement vector between the initial and final position is indicated by Δ X, Δ Y, and Δ Z may be compared to expected or planned displacement vectors, calculated from initial and final position as may be calculated by Δ X, Δ Y, Δ Z as may be more than desired or planned, may be found to be more closely related to the initial and final orthodontic treatment, as may be more closely related to a more than a more accurate endpoint of a tooth replacement, more than a final orthodontic treatment, a tooth, may be found more, more than a final endpoint, more.

The archwire may be coupled to each bracket by a non-sliding mechanics such that the archwire is fixed relative to each bracket, such as archwire 303. an force may be applied to move teeth via an interproximal curve 302 formed in the archwire adjacent to the brackets, as described elsewhere herein.

In figures 5A and 5B, there is schematically shown an example of an archwire 500 with a modified distal end, the right and left ends of the archwire may be further configured to form atraumatic tips 502 to avoid any momentary contact with oral tissue within the mouth of the patient causing pain or discomfort to the patient, in doing so, the patient tolerance of the orthodontic appliance may be increased some embodiments, the right and left ends of the archwire 500 may be bent into a tip bend 504 to form atraumatic tips 502. figure 5A schematically shows the distal end of the archwire 500 including the tip bend 504. the tip bend 504 may be configured such that the ends of the archwire are bent back on themselves and directed away from the occlusal direction of the oral tissue of the patient, in a direction toward the teeth, or in some combination thereof toward the distal end of the bracket bend 504 may be configured to direct the right and left ends of the archwire 500 away from adjacent lingual or buccal/labial tissue.

In certain embodiments , the ends of the archwire 500 are covered with a ball/bulbous end 506, thereby enclosing any sharp edges of the archwire 500. the ball 506 may be formed of a biocompatible material (e.g., non-toxic). The ball 506 may be stable such that they do not degrade during orthodontic treatment. the ball 506 may be formed of a polymeric material. the ball 506 may be formed of an adhesive such as those used to bond brackets to teeth (adhesives may be applied to the right and/or left ends of the archwire.) in certain embodiments , the ball 506 may be formed of a soft elastomeric material (e.g., PVS). the ends of the archwire 500 may be dip coated with a biocompatible material. the biocompatible material may be injected or coated onto the left and right ends of the archwire 500. in certain embodiments , the biocompatible material may be cured (e.g., heat or light cured) on the ends of the archwire 500. curing may be achieved by standard dental instruments (e.g., dental curing lights). in certain embodiments , the biocompatible material may be cured by air drying, and/or after curing to form a non-invasive archwire, the ball 506 may be heated and/or a self-curing adhesive may be applied to a silicone rubber, or a self-retaining ring or a wire.

In certain embodiments , the right and left ends of the archwire 500 may be secured within the furthest right and left brackets such that they do not protrude from the brackets, for example, the archwire 500 may contain a plurality of male fasteners, wherein each male fastener secures the archwire to brackets such that the archwire cannot slide laterally (in the mesial-distal direction) with respect to the brackets, the right and left ends of the archwire 500 may be formed sufficiently close to the interior of the male fasteners away from the right and left furthest male fasteners such that they do not extend out of bracket slots configured to receive the archwire, for example, with respect to the distal brackets, the archwire may terminate at or near its distal ends as shown in fig. 3.

Systems, devices, and methods for registering a non-sliding archwire with an orthodontic bracket are disclosed herein. Orthodontic appliances employing non-sliding mechanics may include archwires with interproximal and/or convex fasteners, as described elsewhere herein. Each interproximal curve may be positioned between two male fasteners. The interproximal curvature may be configured to apply precise forces to two adjacent brackets to correct the positioning of the teeth to which the brackets are bonded. Surrounding male fasteners may be used to secure the archwire to those adjacent brackets in a non-sliding manner. Because the archwire may include a plurality of interproximal curvatures that are specifically configured with corrective forces for different tooth groups, and because the archwire locks into a plurality of brackets in a non-sliding manner, registration of the archwire with brackets that are bonded to a particular tooth is not trivial, especially in comparison to orthodontic appliances that rely on sliding mechanics. If the archwire is not properly registered to the corresponding orthodontic bracket (mis-registration), proper orthodontic treatment may not be achieved. A system that allows for rapid and effective registration may also save time and effort during delivery to a patient relative to orthodontic appliances that correct registration errors.

In embodiments, the archwire is registered to the brackets using a color registration system.A color registration system may include placing different color indicia on the archwire and the bracket to which the archwire is to be locked.A color may be marked at or near the male fastener element or other locking element corresponding to a given bracket.A color may match the color of the indicia on the respective bracket.A embodiment, each fastener/bracket combination is assigned a different color (e.g., red, blue, green, yellow, orange, black, etc.. in embodiments, the same color may be reused.for example, adjacent brackets/fasteners may be marked with alternating colors or the left and right sides of the mouth may use the same color for the respective left and right teeth.in embodiments, the orthodontic appliances are applied to the upper and lower jaws.

The bracket may be configured to receive the archwire in a generally clear configuration, such as may be visible in the bracket when the bracket is inserted into the bracket, such as may be visible in the bracket, may be configured to receive the bracket in a generally clear configuration, such as may be visible in the bracket, may be configured to receive the bracket in a generally clear configuration, such as may be visible in the bracket, may be configured to receive the bracket in a generally clear configuration, may be visible in the bracket, may be configured to receive the bracket, may be visible in a generally clear configuration, may be visible in the bracket, may be configured to receive the bracket, may be visible in a generally clear configuration, may be visible in the bracket, may be configured to receive a generally visible configuration, may be configured to receive a generally visible in the bracket, may be configured to receive a generally visible in the bracket, may be visible in a generally visible in the bracket, may be visible configuration, may be configured to receive a generally visible in the bracket, may be configured to receive a generally visible in may be visible in the bracket, may be configured to receive a generally visible in the bracket, may be visible configuration, may be visible in the bracket.

In embodiments, colored wires, bands, or rubber bands may be placed around the brackets or portions of the brackets the wires, bands, or rubber bands may be removed prior to registering the archwire in each bracket the wires, bands, or rubber bands may be cut away after the archwire is registered with the brackets the wires, bands, or rubber bands may occupy the space of the laces (which are configured to facilitate securing the archwire to the brackets) and may be removed prior to placement of the laces the present invention encompasses a combination of the colored marking systems disclosed herein in embodiments each bracket and corresponding fastener (or identifying portion of an archwire) will be color coded in embodiments only selected brackets and corresponding fasteners will be color coded in embodiments partial bracket to archwire registration may be sufficient to improve the efficiency of archwire to bracket registration.

The stop may be formed by bending or more of the archwire to form a male fastener with a curvature such as a U-shaped curvature, a V-shaped curvature, a tear-drop shaped curvature, etc., or may be formed as a body piece of material extending from the archwire.for example, the stop may be a post extending away from the archwire, a thin plate extending from the archwire, a tube around the archwire axis, or a deformable portion of the archwire.

In another example, the archwire is inserted into the partial tube and the partial tube is crimped around the archwire, or a flange from the bracket is crimped around the archwire and crimped to secure the archwire in place.

In embodiments, the crimpable stop is a tube disposed about an archwire, the tube may slide over a distal end of the archwire, in embodiments, the tube may have a slot along a length of the tube, or the tube may include only a partial circumference, which may allow the tube to be disposed about the archwire without sliding it over the distal end.

In embodiments, the crimpable stop 600 may include a closed circumference and may be advanced over a distal end of an archwire 602. in embodiments, the crimpable stop 600 may be partially closed (e.g., may include a slot along the length of the stop) and may be advanced (e.g., slid) over the distal end or placed directly over the archwire 602 (i.e., the archwire 602 may be inserted into the crimpable stop 600 through the slot). In embodiments, the crimpable stop may be tubular but may include a non-cylindrical shape. for example, the crimpable stop 600 may have a square, rectangular, triangular or other polygonal shape, or the crimpable stop may have an oblong cross-section. the crimpable stop 600 may be used as or replace a male fastener element described elsewhere herein for securing the crimpable stop 602 to the bracket 604 in a non-sliding manner. the crimpable stop 600 may be configured to be received along a substantially straight or linear crimp channel recess 606 in the orthodontic bracket housing pocket 606, the archwire length of the bracket may be configured to be slightly greater than the length of the crimpable stop 606 in the bracket pocket 606.

In embodiments, crimpable stop 600 may be applied to an archwire 602 prior to insertion of the archwire 602 into an orthodontic bracket 604 as described elsewhere herein, the size of recess 606 may be designed or otherwise configured to allow at least partial insertion of a crimping tool (e.g., a clamp, crimper, grasper, etc.) crimping the crimpable stop 600 to the archwire 602 may securely hold the stop 600 and archwire 602 together such that the archwire cannot advance axially (e.g., slide) through the crimpable stop 600 even under forces from adjacent curvature, in embodiments, crimpable stop 600 may be applied to the archwire 602 after insertion of the archwire 602 into the orthodontic bracket 604. in embodiments, crimpable stop 600 may be applied and crimped prior to insertion of orthodontic bracket 602 into the orthodontic bracket 604. if multiple crimpable stops 600 are used, the sequence of applying and crimping may be the same or different for each crimpable stop 600.

Figure 6B illustrates an embodiment of an archwire 602 including between adjacent bends 603 and tubular crimpable stops 600 (indicated by circles) positioned between the adjacent bends to securely fix the archwire 602 to brackets on the lower anterior teeth.
