DETAILED DESCRIPTION OF THE INVENTION

[0071] Referring now to FIG. 1A, and in accordance with at least one embodiment of one or more of the present inventions described herein, an orthodontic appliance in the form of a buccal tube 10 is shown, wherein the buccal tube 10 incorporates features to reduce the binding friction developed between the buccal tube 10 and a device inserted into the buccal tube 10. For example, the present invention includes buccal tubes 10 having at least one archwire slot 14 with friction reducing features for improved interaction with an archwire. The present invention is applicable to a buccal tube 10 having only one archwire slot 14, or to a buccal tube 10 having a plurality of archwire slots 14. In addition, as can appreciated by those skilled in the art, it is to be understood that the present invention is applicable to a buccal tube 10 that utilizes one or more archwire slots 14 in combination with other elongated openings, such as auxiliary tubes, headgear tubes and appliance slots. Accordingly, archwire slot is used to generally define an elongated opening that is adapted for receiving an archwire. However, as used herein, the more generic term archwire/appliance slot/tube means an elongated opening that is adapted for receiving either an archwire or some other type of appliance.

[0072] For the buccal tube 10 shown in FIG. 1A, the buccal tube 10 features two archwire slots (or appliance slots/tubes), namely, archwire/appliance slot/tube 14a and archwire/appliance slot/tube 14b. Accordingly, the buccal tube 10 of FIG. 1A may be characterized as a first molar, double non-convertible buccal tube with a hook. Although a non-convertible buccal tube is shown in FIG. 1A, it is to be understood that aspects of the present invention are also applicable to convertible buccal tube brackets, such as those disclosed in U.S. Pat. No. 6,428,314 entitled Convertible Buccal Tube and U.S. Provisional Patent Application Ser. No. 60/795,611 entitled Orthodontic Bracket With Convertible Buccal Tube; the contents of the foregoing patent and patent application are incorporated herein by this reference in their entireties. Furthermore, the present invention is also applicable to buccal tubes having one, two, three or more archwire/appliance slots/tubes 14. For example, in accordance with embodiments of the present invention, FIG. 1B depicts a first molar, single non-convertible buccal tube 10 with a hook.

[0073] The use of multiple archwire/appliance slots/tubes in the same buccal tube allows the treating orthodontist to apply a single buccal tube to the patient's tooth, and utilize either one or more than one of the archwire/appliance slots/tubes. For the buccal tube 10 shown in FIG. 1A, the orthodontist could use one or both of the archwire/appliance slots/tubes 14a, 14b during the various phases of treatment. Among its uses, the different archwire/appliance slot/tube locations on the buccal tube allow for the force/torque to be applied to the tooth along different points or lines of influence for each archwire/appliance slot/tube 14a, 14b.

[0074] For the buccal tube 10 shown in FIG. 1A, each archwire/appliance slot/tube 14a, 14b extends in a mesial-distal direction. Again, the present invention also applies to buccal tubes having one or more than two archwire/appliance slots/tubes, and the following discussion is directed to a single archwire/appliance slot/tube 14a to discuss the features of the archwire/appliance slot/tube. However, the discussion applies equally to other archwire/appliance slots/tubes that may be associated with the buccal tube, such as archwire/appliance slot/tube 14b shown in buccal tube 10 of FIG. 1A.

[0075] In accordance with embodiments of the present invention, the archwire/appliance slot/tube 14a includes an interior opening 18 bordered by four interior sides, namely, a gingival side 22, an occlusal side 26, a buccal side 30, and a lingual side 34. Of course, depending upon the orientation of the buccal tube 10 in the patient's mouth, the gingival side 22 and occlusal side 26 may be reversed.

[0076] In accordance with embodiments of the present invention, at least one of the interior sides 22, 26, 30 and 34, and more preferably, more than one of the interior sides 22, 26, 30 and 34 of the archwire/appliance slot/tube 14a include a feature to reduce the amount of friction developed between an archwire and the archwire/appliance slot/tube 14a. More particularly, for the buccal tube 10 shown in FIG. 1A, the archwire/appliance slot/tube 14a includes a projection 38 residing on at least one of the interior sides 22, 26, 30 and 34. For the buccal tube 10 shown in FIG. 1A, both of the gingival side 22 and the occlusal side 26 include at least one projection 38 to reduce the amount of surface area contact between the side of the archwire and the gingival side 22 and the occlusal side 26 of the archwire/appliance slot/tube 14a. FIGS. 5A and 5B illustrate a version of a buccal tube 10, and FIGS. 5C and 5D illustrate another version of a buccal tube 10. Buccal tubes 10 of FIGS. 5A-5B and 5C-5D, have twin archwire/appliance slots/tubes 14a and 14b, wherein the gingival side 22, occlusal side 26, and buccal side 30 of the interior of the archwire/appliance slots/tubes 14a and 14b each include projections 38. By providing the projections 38 along one or more of the interior sides 22, 26, 30 and 34, the binding friction between the archwire and the buccal tube buccal tube 10 is reduced, thereby providing improved performance of the buccal tube 10 to adjust the patient's tooth. It is noted that at least some embodiments of the present invention do not include a projection along the lingual side 34 of the archwire/appliance slots/tubes 14a and 14b. As discussed in more detail below, the friction reducing features preferably comprises at least one of: (a) a plurality of longitudinally aligned projections residing along a longitudinal length of one or more of the gingival side 22, occlusal side 26, buccal side 30, and lingual side 34; and (b) a longitudinally extending projection residing along a longitudinal length of one or more of the gingival side 22, occlusal side 26, buccal side 30, and lingual side 34. In accordance with embodiments of the present invention, one or more projections are located along at least two of the gingival side 22, occlusal side 26, and buccal side 30 the interior of the archwire slot 14.

[0077] Referring now to FIG. 5E, an embodiment one of a gingival side 22, an occlusal side 26, a buccal side 30, or a lingual side 34 of an archwire/appliance slots/tube 14 is shown, wherein other portions of the buccal tube 10, including the remaining sides, are not depicted for clarity. The mesial end 32 of the interior side 22, 26, 30, 34 includes projection 38a that comprises a rounded feature. The distal end 36 of the interior side 22, 26, 30, and 34 also includes a projection 38b. For the embodiment shown in FIG. 5E, the projection 38a is not continuous with projection 38b along interior side 22, 26, 30, 34. That is, the projections 38a and 38b are spaced apart along a longitudinal length of the interior side 22, 26, 30, 34. Accordingly, projection 38a is longitudinally spaced apart but longitudinally aligned with projection 38b. An archwire A is shown extending in a mesial-distal direction that substantially corresponds to the mesial-distal orientation of the interior side 22, 26, 30, 34. The projections 38a and 38b cause a limited amount of the archwire A to contact a surface of the interior side 22, 26, 30, 34. For the example shown in FIG. 5E, the archwire A has a substantially rectangular or square shape in cross section (although the buccal tubes 10 described herein will receive archwires of different cross sectional shapes, such as round), and a side 40 of the archwire A contacts the projections 38a and 38b along a crown or ridge line 44 of the projections 38a and 38b. As a result, the archwire does not contact the majority of the length of the interior side 22, 26, 30, 34 because the projections 38a and 38b cause the archwire to be spaced apart from the surface 39 of interior side 22, 26, 30, 34, such as by a distance D.

[0078] Referring now to FIG. 5F, there is shown an embodiment of a projection 38 that extends in a longitudinal direction along the interior side 22, 26, 30, 34. Again, other portions of the buccal tube 10, including the remaining sides, are not depicted for clarity. The projection 38 of FIG. 5F substantially comprises a single and continuous curved surface 48 that extends in a mesial-distal orientation. For the example shown in FIG. 5F, again, the archwire A has a substantially rectangular or square shape in cross section, and a side 40 of the archwire A contacts the projection 38 along the longitudinal length of the projection 38. Given that the projection 38 has a curved surface 48 that is exposed to the side 40 of the archwire A, a limited surface area of the archwire/appliance slots/tube 14 contacts the archwire A, thereby reducing binding friction between the archwire A and the archwire/appliance slots/tube 14.

[0079] Referring still to FIGS. 5E and 5F, when multiple interior sides 22, 26, 30, 34 of the archwire/appliance slots/tube 14 include the friction reducing features of the one or more inventions described herein (such as projection 38 or projections 38a and 38b), additional reductions in binding friction are provided. However, the projections 38 (or projections 38a and 38b) still provide control of the archwire A along the longitudinal length of the archwire/appliance slots/tube 14 because the projections 38 (or projections 38a and 38b) engage the archwire A at more than one point along the archwire A.

[0080] Referring still to FIGS. 5E and 5F, the drawings further illustrate tapered ends 54 at the mesial end 32 and distal end 36 of the interior sides 22, 26, 30 and 34. The tapered ends 54 further reduce friction between the archwire/appliance slots/tube 14 and the archwire A.

[0081] Although discussed in terms of a projection 38, the surface area reducing feature may alternately comprise other ways of reducing friction within the archwire/appliance slot/tube 14, including a recess or multiple recesses along one or more of the interior sides 22, 26, 30 and 34. In general, the reduced friction portion of the interior opening 18 limits the amount of surface area that an archwire of any shape will be touching in the length of the opening 18 of the archwire/appliance slot/tube 14a. By way of example and not limitation, and as shown in FIGS. 5A-8D, the projections may take on a variety of shapes. The binding friction is thus reduced, including at the corners 16 of the archwire/appliance slot/tube 14a.

[0082] Embodiments of the reduced friction archwire/appliance slot/tube 14a have application for use in a molar (buccal) orthodontic tube, as well as any buccal tube including molar tubes, regular tubes and brackets of any kind that include a slot/tube structure. For buccal tube 10 shown in FIG. 1A, the buccal tube 10 further comprises a hook 42 for facilitating attachment of another device to the buccal tube 10. However, it is to be understood that the hook 42 is optional.

[0083] In accordance with at least some embodiments of the present invention, the frictional reducing features along one or more of the interior sides 22, 26, 30 and 34 are positioned to provide contact between the one or more of the interior sides 22, 26, 30 and 34 and the archwire at or near at least the mesial and distal ends the archwire/appliance slot/tube 14a, such as shown for one of the interior sides 22, 26, 30, and 34 depicted in FIG. 5E. Alternatively, the friction reducing features extend substantially the entire interior length of the interior sides having the feature, such as shown for one of the interior sides 22, 26, 30, and 34 depicted in FIG. 5F. In this way, the clinical control of the buccal tube 10 is preserved because the archwire/appliance slot/tube 14a is able to influence the archwire along substantially its entire mesial-distal length while still reducing the binding friction associated with contacting the archwire/appliance slot/tube 14a contacting the archwire.

[0084] In a separate aspect of one or more inventions described herein, at least some embodiments of buccal tube 10 include a rounded exterior occlusal surface 52. The rounded occlusal surface 52 provides for improved patient comfort, and thus, better patient satisfaction and cooperation with the treating orthodontist. In accordance with embodiments of the present invention, and as seen in the embodiments illustrated in FIGS. 1A-4 and 8A-8D, the buccal tube 10 incorporates a substantially planar surface portion 56 extending from an occlusal-base edge 60 near the base 64, that leads continuously into a relatively large radius rounded exterior occlusal surface 52 to give the exaggerated rounded surface on the occlusal side of the buccal tube 10. The buccal tube 10 may include a substantially planar surface portion 58 extending from a gingival-base edge 62 near the base 64. Accordingly, in accordance with at least one embodiment of the present invention, the archwire/appliance slot/tube 14 is not completely dome-shaped on the top or buccal side because of (1) the presence of the flat or planar surface portion 56, as well as (2) the presence of planar surface portion 58. The rounded exterior occlusal surface 52 preferably extends substantially the entire mesial/distal longitudinal length L of the archwire/appliance slot/tube 14, and can be a variety of radius sizes depending on the overall size of the archwire/appliance slot/tube 14.

[0085] Referring now to FIGS. 2, 3, 4, 7D, 8B, 8D, and 9A-15B, and in accordance with at least one embodiment of one or more inventions described herein, the buccal tube 10 includes a way for receiving an installation tool. More particularly, the exterior surface 66 may comprise at least one, and more preferably, a pair of tool receiving surfaces or receptacles for communication with an installation tool during placement of the buccal tube 10 on the patient's tooth. The inset receptacles 68 are preferably located on opposite sides of a longitudinally oriented centerline CL-CL of the buccal tube 10 (or on opposite sides of a longitudinally oriented centerline of the archwire/appliance slot/tube 14 if a single slot is present, such as shown in FIG. 1B), such as being inset within the exterior surface 66 of the archwire/appliance slots/tubes 14a, 14b. More particularly, one receptacle 68 is preferably located on the gingival side 72 of the centerline CL-CL, and the other receptacle 68 is preferably located on the occlusal side 76 of the centerline CL-CL of the buccal tube 10. In accordance with embodiments of the present invention, the receptacles 68 include a substantially planar area on the gingival and occlusal sides 72 and 76, respectively, of the centerline CL-CL of the exterior surface 66 of buccal tube 10.

[0086] The receptacles 68 may be configured for use with a direct bond tweezers, such as RMO i-1102/RMO T01102 tweezers. For the buccal tube 10 shown in FIGS. 2-4, the receptacles 68 include a sloped mesial edge 80 trending in a mesial to distal direction from the buccal to the lingual side of the receptacle 68. In contrast, the distal end 84 of the receptacles 68 is typically not sloped in a mesial to distal direction. The receptacles 68 further include a lingual ledge 88. By way of example and not limitation, FIGS. 2, 3, 4, 7D, 8B, 8D, and 9A-15B include a variety of shapes that may be used to form the receptacles 68.

[0087] In accordance with embodiments of the present invention, the appliance may comprise at least one receptacle in the exterior surface, the receptacle comprising a tool receiving surface adapted for cooperating with a placement tool, the tool receiving surface comprising a single projection and a single indentation. In accordance with embodiments of the present invention, the appliance may comprise at least a second receptacle in the exterior surface, the second receptacle comprising a tool receiving surface adapted for cooperating with the placement tool, the tool receiving surface comprising a single projection and a single cavity or indentation. In accordance with embodiments of the present invention, the appliance may comprise at least one receptacle in the exterior surface, the receptacle for receiving a tool that applies a force directed outward from a center of the receptacle.

[0088] In use, the shape of the receptacle 68 cooperates with the angle of the installation tool or tweezers, such that the installer of the buccal tube 10 is able to manipulate the buccal tube 10 to go straight into the patient's mouth, thus relieving the installer of relatively large movements of the cheek.

[0089] Referring now to FIG. 16, and in accordance with at least one embodiment of one or more inventions described herein, a buccal tube 10 is shown having a pair of archwire/appliance slots/tubes 14a and 14b. The first archwire/appliance slot/tube 14a is substantially circular in cross section and includes a plurality of projections 38. The projections limit the surface area contact between the exterior sides of the archwire A and the interior of the archwire/appliance slot/tube 14a.

[0090] In a separate aspect of one or more embodiments of the one or more inventions described herein, a buccal tube 10 is provided that has at least one archwire/appliance slot/tube that includes projections for reducing frictional interaction with an archwire, and at least one archwire/appliance slot/tube that does not include projections, such as for reducing frictional interaction with an archwire. Referring again to FIG. 16, the first archwire/appliance slot/tube 14a includes at least one projection 38, and a second archwire/appliance slot/tube 14b is depicted that does not include a projection 38.

[0091] In accordance with embodiments of the present invention, a method of adjusting the position of a tooth is provide, the method including attaching a buccal tube to a tooth and inserting an archwire through an archwire slot in the buccal tube. The method further includes limiting surface contact of the archwire along a portion of the longitudinal length of the archwire slot by contacting an exterior surface of the archwire with friction reducing features located within the archwire slot. More particularly, the method includes contacting the exterior surface of the archwire with one or more of the interior sides of the archwire slot, wherein the interior sides include a gingival side, an occlusal side, a buccal side, and a lingual side. The friction reducing features preferably comprises at least one of: (a) a plurality of projections residing along a longitudinal length of one or more of the gingival side, occlusal side, buccal side, and lingual side; and (b) a longitudinally extending projection residing along a longitudinal length of one or more of the gingival side, occlusal side, buccal side, and lingual side. In accordance with embodiments of the present invention, one or more projections are located along a plurality of the gingival side, buccal side, and lingual side of the interior of the archwire slot.

[0092] It should be understood that the scope of the present invention includes the use of a plurality of passageways, including at least one passageway, and more preferably, at least two passageways, and potentially three or more passageways in any particular device. Such passageways can be configured in various symmetrical shapes and configurations to include squares, rectangles, triangles, polygons, octagons, flat and curved sided configurations, etc. In a preferred embodiment, the geometrical configuration of a passageway mirrors the general exterior shape of an archwire used with such appliance. It is also within the scope of the present invention that frangible covers abutting or extending over an archwire placed within the orthodontic device of the present invention, be removable and/or adjusted in ways desired by an orthodontist. Thus, for example, materials rounding receptacle 68 can be constructed so as to be frangible and thus removable at some point in time after desired placement of a device and/or for orientation thereof. The number of receptacles 68 can include, for example, at least one receptacle suitable for manipulation by an orthodontist, but may also include one or more, two or more, or three or more such receptacles, which can, in certain embodiments, be adapted to correlate with the prongs of a receptacle engaging device or insertion tool. One of skill in the art will also appreciate the scope of the present invention includes the use of different geometrically configured passageways, such that a square archwire can be used in one passageway, whereas a round archwire can be used in an adjacent passageway, etc., with the passageways having a similar exterior configuration as the archwire utilized in such applications. Alternatively, the passageway or archwire slot may have a different geometric shape than that of the archwire used.

[0093] In summation, a buccal tube is provided that includes a number of novel features, including a friction reducing profile within the buccal tube opening, modified exterior shaping to facilitate improved comfort, and a plurality of positioning notches, buccal recesses, gripping portions or placement notches for receiving an installation tool. For the above-described buccal tube 10, placement of the archwire/appliance slot/tube 14 on a band can cover any angle, mesial/distal locations, gingival/occlusal locations, and any direct bond applications.

[0094] One or more inventions may be described herein, and embodiments shown and/or described may comprise one or more of the inventions.

[0095] A number of variations and modifications of the invention can be used. It would be possible to provide for some features of the invention without providing others. For example, in one alternative embodiment, a low friction archwire/appliance slot/tube may be used without a rounded exterior occlusal surface, and without the installation tool receiving receptacles. In another alternative embodiment, the receptacles may be used on a buccal tube having gingival and occlusal surfaces, but without a low friction archwire/appliance slot/tube for receiving an archwire, and without a rounded exterior occlusal surface.
