Definitions
- the invention is based on a bracket with the features specified in the preamble of claim 1.
- a bracket is known from EP 2 381 880 B1.
- the known bracket has a slide for closing its groove, which is also referred to in technical terms as a “slot”, which can be displaced in lateral guide grooves which are provided both in the occlusal wall and in the gingival wall of the bracket.
- a recess open to the slide is provided in one of the two walls of the bracket, in which a yielding abutment is provided, on which an unyielding cylinder lies, which with its The lateral surface protrudes a little from the recess and is pressed by the flexible abutment against the underside of the slide, which is its lingual side.
- this arrangement of the abutment and the cylinder lying thereon fulfills its task of holding the slide both in its open position and in its closed position.
- special care and a corresponding manufacturing effort are required when installing the abutment and the cylinder lying thereon in the bracket.
- the present invention has for its object to show a way in which the effort for the manufacture and assembly of the bracket can be reduced in a bracket with the small dimensions of the type mentioned.
- the bracket according to the invention has
- a slide which has a labial side and a lingual side and is held in a guide provided in the occlusal wall and / or in the gingival wall and in the guide between a closed position in which the slide bridges the groove and an open position in which the groove is open in the labial direction, can be displaced in the gingival-occlusal direction,
- these means include in the gingival wall and / or in the occlusal wall a recess which is open towards the slide and in which there is a locking element which has a convex labial end which protrudes from the recess and is directed against the lingual side of the slide and has a lingual end located in the recess;
- a first depression and a second depression are provided and arranged in such a way that the the protruding convex end of the locking element engages in the first depression when the slide is in its open position and engages in the second depression when the slide is in its closed position;
- the locking element is guided to and fro in the recess in the lingual-labial direction and has one or more elastically or elastomerically bendable prongs which have an end pointing in the direction from labial to lingual and when the locking element is moved back and forth on one the locking element slide surrounding wall of the recess;
- the recess narrows in the direction from labial to lingual, the recess and the locking element being matched in their shape and position so that when the slide is pushed over the convex end of the locking element and thereby the convex end of the locking element out of the first or second depression is displaced out and deeper into the recess, at least one of the prongs in the narrowing portion of the recess is deflected by the wall, on which it slides deeper into the recess, and is bent elastically or elastomerically.
- bracket according to the invention instead of the arrangement provided in the prior art from a flexible abutment and a hard cylinder lying thereon, only a one-piece locking element is provided.
- the locking element can be manufactured inexpensively and with the required accuracy by injection molding.
- the locking element has a convex end and is positioned in the recess of the bracket in such a way that the convex end protrudes from the recess.
- the surface of the convex end can, if the locking element has a rectangular cross section, part of a cylinder jacket be surface that protrudes from the recess in the same way as the lateral surface of the cylinder does in the prior art. The consequence of this is that the slide of the bracket can be adopted unchanged from the prior art according to EP 2 381 880 B1.
- the locking element can also have a circular cross section.
- the convex end can then be spherical, in particular with a surface in the form of a spherical section surface.
- the recess is designed as a slot extending through to the underside of the bracket. This made it possible to push the abutment into the slot from the underside, to position it exactly at the appropriate distance from the upper edge of the recess and to fix it in this position using adhesive that was inserted into the slot from below.
- a recess is provided according to the invention, which has a tapering section at some distance from its upper, labial edge, into which the locking element provided with one or more prongs can be pushed resiliently.
- the recess does not have to be open to the underside of the bracket. Therefore, regardless of the recess, the underside of the bracket can be structured and provided with retentions as is best for coating the underside with adhesive for fastening the bracket to a tooth. •
- the formation of the recess as a blind hole does not require a special operation, but can be formed in the course of the manufacture of the bracket by an injection molding process, namely in the manufacture of the bracket from plastic by a plastic injection molding process, in the manufacture of the bracket from metal by metal powder injection molding (MIM), and when manufacturing the bracket from a ceramic by ceramic powder injection molding (CIM). If a circular outline is selected for the locking element, the recess receiving the locking element can also be a bore.
- the locking member according to the invention can be made very compact and is therefore particularly suitable for miniaturized self-ligating brackets preferred by patients.
- the locking member according to the invention can be easily positioned in the bracket.
- the positioning of the locking member according to the invention can be automated. This reduces the cost of manufacturing the bracket.
- the locking member according to the invention is housed and guided in the recess protected from overload.
- the locking member according to the invention can effectively prevent the undesired penetration of foreign substances into the recess.
- convex is understood in the context of the present invention in a mathematical sense.
- a strictly convex surface is characterized by the fact that for all pairs of points on the strictly convex surface, a straight line that connects two points on the surface intersects the surface.
- a convex in the sense of the invention is also a surface on which the straight lines connecting them for a first subset of the point pairs on the surface intersect the surface, while the straight lines connecting them run for a second subset of the point pairs. The latter applies to a convex surface that can be cut through a plane so that the cutting line contains a polygon.
- the second depression, in which the locking element engages in the closed position of the slide is preferably deeper than the first depression, in which the locking element engages in the open position of the slide.
- the locking element has exactly two prongs which are arranged in the manner of a fork and are configured and arranged identically or in mirror image.
- both tines can make equal contributions to the restoring force due to their bending.
- the two prongs are not the same to train so that they are unequally stiff.
- one prong can be designed so stiff that it is not or only slightly bent, whereas the other prong is easier to bend and essentially only provides the necessary restoring force due to its bending.
- the recess receiving the locking element preferably has a constant cross-section at its labial edge, initially at a portion of its depth, and then tapers thereon. Accordingly, in this case, the locking element has a constant cross-section at a certain length following the convex end, which corresponds to the constant cross-section of the recess, and then the one or more tines.
- the two constant cross-sections not only ensure that the locking element is moved in the same direction, but can also prevent foreign matter from entering the recess.
- the tines immersed in the tapered section of the recess build up the restoring force by which the locking element is advanced in the closed position and in the open position of the slide for locking it into the relevant recess on the lingual side of the slide.
- the recess preferably narrows steplessly, but the wall of the recess may bend at the transition from the section with a constant cross section to the section with a tapering cross section.
- the locking element is preferably made of a plastic in which the easy formability combines with the desired elastomeric or elastic behavior.
- the locking element can be formed from a transparent or translucent plastic.
- the bracket also consists of a transparent or translucent material, which can be a plastic or a ceramic.
- Suitable plastics for the blocking element are, for example, polyaryl ether ketones, in particular a polyether ether ketone (PEEK).
- the blocking element has a rectangular cross section in its non-tapered section.
- the recess also has a rectangular cross section in its non-tapered area.
- the recess tapers preferably in a wedge shape.
- the two wedge surfaces preferably form an angle of 80 ° to 100 °, preferably approximately 90 °. The invention can thus be implemented well with the small displacement distances which are possible with the small brackets and which are typically only 0.3 mm.
- a locking element is preferably provided with only two prongs arranged in the form of a fork, which preferably have at their ends an inclined surface which faces the adjacent wall surface of the recess.
- the tines can rest flatly, in particular over the entire surface, in the tapered section of the recess of the wall of the recess, optionally also with their preferably provided inclined surface.
- the arrangement of the locking element can be chosen so that its convex end exerts no or almost no pressure on the slide when the slide is in its closed position or in its open position.
- a stop is preferably provided on the body of the bracket, which prevents the slide from being shifted beyond its closed position when it is moved from its open position into its predetermined closed position.
- the stop is preferably arranged in such a way that the slide, coming from the occlusal direction, is pushed in the gingival direction when it is moved against the stop from the open position into the closed position.
- the lingual side of the pusher - apart from the first and the second recess - can be flat. This is a particularly easy to manufacture shape for the slide.
- the slider can also be structured on its lingual side in such a way that it is not only delimited by a flat surface outside the first depression and the second depression.
- the lingual surface of the slider with the exception of an area that projects between the first depression and the second depression, lies in a common plane relative to these, whereas the area lying between the first depression and the second depression also lies opposite that common level is deepened, but less deepened than the first deepening and the second deepening.
- the recessed area on the lingual side of the slide between the first depression and the second depression can also be flat.
- the second depression is preferably deeper than the first depression. This ensures that the slide is better secured in its closed position than in its open position.
- the contour of the second depression is preferably approximately adapted or closely adapted to the contour of the convex end of the locking element. This has the advantage that the slider is particularly secure in its closed position and with very little play. This advantage does not play such an important role for the open position of the slide, so that the contour of the first depression of the shape of the convex end of the locking element is without disadvantage may be less well adapted.
- the first depression may be a flat trough.

- Blocking element is cut, with the slide in its closed position
- FIG. 10 shows a section as in FIG. 9 with the slide in an intermediate position between the open position and the closed position
- Figure 11 shows a section as in Figure 9 with the slide in its open position.
- the bracket shown in Figures 1 to 7 has a concave base 1, the curvature of which approximates the front of a tooth.
- the base 1 has on its underside 2, which forms the lingual side of the bracket, recesses 3 arranged in rows with an approximately rectangular cross section.
- An adhesive can be applied to the underside 2 in order to glue the bracket onto a tooth. The adhesive interlocks with the recesses 3.
- the base 1 merges into a base 4 on which there is a gingival wall 5 and an occlusal wall 6.
- the two walls 5 and 6 run parallel to each other and are separated by a groove 7, which is also referred to in orthodontics as a “slot” and runs in a straight line from distal to mesial and is open to the labial.
- a ligature wing 8 projecting in the direction of the gingival is provided on the gingival wall 5.
- a ligature wing 9 projecting in the direction of the occlusal direction is provided.
- Ligature wires can be attached to them in a manner known to those skilled in the art.
- the ligature wings 8 and 9 can each be divided into a pair of correspondingly smaller ligature wings, which lie side by side in the direction from distal to mesial.
- the ligature wing has a hook-shaped extension 9a, which is of no importance for the present invention.
- the invention is suitable for both Brackets with such an extension 9a as well as for brackets without such an extension 9a.
- the groove 7 serves to receive a wire arch, which is not part of the bracket and is therefore not shown. By tensioning the wire arch, pressure can be exerted on the base 10 of the groove 7 and a torque can be exerted on the walls 5 and 6 of the bracket.
- a labial recess 14 in the gingival wall 5 and a labial recess 15 in the occlusal wall 6 receive a mainly flat slide 13 with an essentially rectangular plan.
- the recesses 14 and 15 have mutually parallel undercuts 11 and 12 which run from occlusal to gingival and which together with the base 17 of the recess 15 and the base 20 of the recess 14 form slide guides for the slide 13, which the slide 13 does not in the labial direction can leave because the undercuts 11 and 12 prevent this.
- the recesses 14 and 15 are in common alignment.
- the recess 14 crosses the occlusal wall 6, whereas the recess 15 ends in the gingival wall 5 at a stop, which is the “second” stop 18 mentioned in the claims.
- the slide 13 can be moved back and forth in the guide formed by the recesses 14 and 15 and by the undercuts 11 and 12 in the gingival-occlusal direction between an open position in which the slide 13 is only held in the occlusal wall 6, and a closed position, which is shown in Figures 5 to 7.
- the groove 7 is open in its full width from the labial side.
- the front end 19 of the slide 13 preferably closes with the surface of the occlusal wall 6 delimiting the groove 7.
- the front end 19 of the slide 13 strikes the second stop 18 on the gingival wall 5, as is shown particularly clearly in FIG.
- the slide 13 bridges the groove 7, so that a wire arch running therein cannot leave the groove 7 in the labial direction.
- the occlusal wall 6 there is a slot-shaped recess 21 which extends mainly parallel to the surface of the occlusal wall 6 delimiting the groove 7.
- the mutually opposite surfaces 21a and 21b of the recess 21 which extend in the direction of the groove 7 run parallel to one another, see FIG. 7.
- the wall surfaces 21c and 21d running at right angles to the surfaces 21a and 21b and at right angles to the groove 7 run in one section adjacent to the labial edge 21e of the recess 21 parallel to one another.
- the wall surfaces perpendicular to the surfaces 21a and 21b are no longer arranged parallel to one another but at an acute angle to one another and are therefore referred to here as wedge surfaces 21f and 21g. They close the recess 21 before reaching the underside 2 of the bracket, that is, in this section the recess 21 tapers in a wedge shape, as shown in FIGS. 4 and 6.
- the locking element 22 shown in FIG. 2 is inserted in the recess 21 and is guided therein in a labial-lingual direction between the position shown in FIG. 4 and the position shown in FIG. 6.
- the locking element 22 has a convex labial end 22a, which in the present exemplary embodiment has the shape of a section of a cylinder jacket surface. This is followed by an arch-like body 23, which may have chamfers 24 on its outer edges for easier insertion into the recess 21.
- the arch-like body 23 is formed from two tines 25 running parallel to one another and a head part 26 connecting them, which carries the convex end 22a of the locking element 22.
- the tines 25 have inclined surfaces 27 at their lingual ends 22b, the inclination of which corresponds to the inclination of the wedge surfaces 21f and 21g. In the relaxed state, as shown in FIGS.
- the inclined surfaces 27 of the locking element 22 therefore lie over the entire surface on the wedge surfaces 21f and 21g of the recess 21, see FIG. 4, which shows the state with the slide 13 in its closed position - position shows.
- the two prongs 25 are arranged in a fork shape and are designed to taper in the lingual direction to match the wedge surfaces 21f and 21g.
- the locking element 22 consists of a material, in particular a plastic, which is elastically or elastomerically deformable.
- the tines 25 can therefore be brought closer to one another by external pressure. The pressure from the outside can be applied in that the blocking element 22 is pressed deeper into the recess 21 by pressure on its convex end 22a.
- the inclined surfaces 27 of the tines 25 slide in the lingual direction, that is to say toward the underside 2 of the bracket, and are forcibly brought closer to one another by bending, as shown in FIG. 6, which shows the state in which the slide 13 is in a position between the closed position and the open position.
- the tines 25 can be brought closer to one another because, because of the arch-like shape of the body 23, as shown in FIGS. 2, 4 and 6 and in FIGS. 8 to 11, there is a free space between the two tines 25.
- the convex end 22a projects beyond the edge 21e of the recess 21 by the greatest possible extent.
- the entire cylinder jacket surface at the convex end 22a is located above the edge 21 e and is located in a cylinder jacket-shaped second depression 28 on the underside (lingual side) of the slide 13.
- the second depression 28 and the convex end 22a of the locking element 22 go into this Position a positive lock that secures the closed position of the slide 13.
- the slide 13 In order to move the slide 13 from the closed position into its open position, the slide 13 is pushed to the right in the sense of the illustration in FIG. 7, which can be done by engaging a recess 16 in a plunger which extends in the upper side (in the labial side) of the slide 13 is provided. Due to the pressure exerted to the right in the sense of FIG. 7 on the slide 13, a downward force is exerted on the slide element 22 in the region of the second recess 28, so that it is pressed deeper into the recess 21, whereby the Tines 25 builds up a restoring force. A lower projection 29 adjoins the second depression 28 on the underside of the slide 13.
- the locking element 22 When this has slid onto the convex end 22a of the locking element 22, the locking element 22 has its deepest Point in the recess 21 reached, as shown in Figure 6.
- the low projection 29 separates the first depression 30 and the second depression 28 from one another.
- the low projection 29 can be arranged recessed relative to the edge regions 37 and 38 of the lingual side of the slide 13, but less recessed than the first recess 30 and the second recess 28.
- the low projection 29 is adjoined by a flat recess on the underside of the slide 13, which ends at a stop 25.
- the flat recess is the “first depression” 30 mentioned in claim 1.
- the slide 13 has its first depression 30 slides onto the locking element 22, this can spring back out of the recess 21 by an amount which is determined by the distance between the lingual surface of the projection 29 and the bottom of the first depression 30. This results in an engagement between the convex end 22a of the locking element 22 and the first recess 30, through which the slide 13 is held in its open position.
- the first recess 30 only serves to prevent the slide 13 from unintentionally returning to its closed position.
- This securing does not have to be as reliable as securing the closed position, because the open position is only required during the treatment of a patient in orthodontic practice.
- the closed position is better secured because it is intended to prevent the slide 13 from being opened unintentionally outside of orthodontic practice, in particular when chewing food or chewing gum, and thereby making it possible for a wire arch lying in the groove 7 slides out.
- a loss of the slide 13 from the open position is prevented by a stop 31 delimiting the first recess 30 on the underside of the slide 13.
- FIG. 8 shows a section of the occlusal wall 6 of a bracket of the type shown in FIGS. 1 to 7, a section being made through the longitudinal center plane of a section of the slide 13. Below the median longitudinal plane is understood to mean that plane which intersects the slide 13 in the middle, which extends at right angles to the longitudinal extent of the slot 7 and also cuts the base 10 of the slot 7 at a right angle (see FIG. 7).
- the blocking element 22 is essentially a cylindrical body which is slotted from the lingual end to form two prongs 25 and continues into a truncated cone 34 towards the labial end whose tip 22a, the labial end of the locking element 22, is a circular area.
- the locking element 22 is inserted in a bore 36 with a cylindrical section and an adjoining conical section.
- the first depression 32 and the second depression 33 are conical in the lingual side of the slide 13.
- the slide 13 is guided in two undercuts, of which only one undercut 12 is shown in FIGS. 8 to 11 due to the selected cut.
- FIGS. 8 and 9 show the slide 13 in its closed position, in which the truncated cone 34 of the locking element 22 engages in the conical second recess 33, the opening angle of which corresponds to the opening angle of the truncated cone 34.
- Figure 10 shows the slide 13 in an intermediate position between its closed position and its open position.
- the slide 13 has pressed the locking element 22 deeper into the bore 36, as a result of which the tips of the two prongs 25, which rest with their inclined surfaces 27 in the closed position (FIGS. 8 and 9) on the conical surface of the bore 36 were.
- the projection 29 of the slide 13 lying between the two conical depressions 32 and 33 lies on the labial end 22a of the locking element 22, which presses due to the bending stress in the tines 25 against the underside of the extension 29.
- FIG. 11 shows the slider 13 in its open position, in which the conical first recess 32 lies above the bore 36 and the blocking element 22 has moved with its truncated cone 34 into the first conical recess 32, by reversing the bending of its prongs 25.
- the two conical depressions 32 and 33 are of the same depth in this example.
- Locking element 38 an edge area of the
