INVENTOR, MELVIN WALLSHEIN,

ATTORNEY.

ORTHODONTIC SYSTEMS The present invention relates to, and its principal object is to provide, novel and improved orthodontic systems involving an arch wire, bracket-holding tooth bands and pressure-applying elements, arranged in novel functional relationships offering new modes of operation with positive adjustments and movements accomplishing planned results toattain proper correction. Also of prime importance of these systems is the accomplishment of tooth movement by shift of its root even appreciable distances.

A further object of this invention is to provide novel and improved orthodontic systems of the character described, involving fittings for associating with the teeth, which are simple in construction, easy to mount and bring into cooperation, and to afi'ord adjustment of all acting forces indivdually, without affecting the action of the others, and which systems are of economical make-up, easy to install and manipulate, presenting no discomfort to the patient, and which are eflicient in carrying out the purposes for which they are designed.

Other objects and advantages will become apparent as this disclosure proceeds.

In the practice of this invention, the arch wire is never called upon to exert any force against any tooth; the arch wire being of rigid material mounted fixed in position in bracket-holding tooth bands on selected teeth. Every tooth whose root is to be shifted, has one of such bands thereon, and the bracket it presents is rotatably mounted on the arch wire. Any tooth to be swung in about its root tip as an axis, needs no band thereon, The arch wire serves as a scaffold to support pressure-exerting spring finger elements, each of which in the embodiments shown, consist of a split sleeve from which laterally extend at least one resilient cantilever spring which is bent as needed to press on a tooth, its band or against part of the bracket, and is adjustably stressible. Each sleeve has a set crew to secure it to the arch wire. These sleeves may be snapped onto the arch wire, slid thereon to required position, turned thereon a desired extent to stress their spring fingers, and then tighten them in position. The spring fingers usually are L-shaped and may impose their force against more than one tooth. Thefingers on one sleeve may act against difierent teeth, or cumulatively against the same tooth. Said fingers may be of any length, bendable into various shapes, and as will be shown, when U-shaped, may be made to serve also in place of tie wires.

In the accompanying drawing forming part of this specification, similar characters of reference indicate corresponding parts in all the views.

FIG. 1 is a side view of upper teeth showing one practice of this invention. I

FIG. 2 is an enlarged fragmentary perspective view of a force-exerting element structure whose bendable, resilient fingers may be of any length. Such element may be supplied as a stock part to an orthodontist who can remove any fingers thereof he does not need for a particular installation, and which he may bend and trim as required.

FIGS. 3, 4, and 5 are enlarged perspective views of similar-purpose elements, after different parts of the item of FIG. 2 are cut off, so what is left in each instance is what is particularly needed. Of course, these fittings can be offered as ready stock parts.

FIG. 6 is an enlarged perspective view of another force-exerting element structure of a construction formed of the stock part of FIG. 2, showing one finger fashioned to serve to engage and support the arch wire, in lieu of use of a tie wire.

FIG. 7 is an enlarged perspective view showing a tooth band carrying a bracket of the type convenient for use in the systems shown.

FIG. 8 is a fragmentary enlarged side view of upper teeth dealt with in different manners in accordance with this invention, particularly showing several aarrangements for the shifting of teeth in various ways.

FIG. 9 is a section taken at line 9-9 in FIG. 8, and particularly shows how a tooth is shifted about the arch wire as an axis, whereby the root of the tooth is moved towards the tongue.

FIG. 10 is an enlarged side view showing the forceexerting element in its initial position, mounted on the arch wire and set to the tooth a resilient finger thereof is to act on. Said finger is here in untensed condition and the sleeve is loose.

FIG. 11 is a view like FIG. 10, where the sleeve has been turned to flex its finger, and in such position, is secured by its set screw to the arch wire. FIG. 12 is a section taken at line 12-12 in FIG. 8, showing another way how a tooth is shifted about the arch wire as an axis, whereby its root is moved towards the tongue.

FIG. 13 is an enlarged fragmentary view showing one way how a tooth is shifted about the arch wire as an axis whereby its root is moved away from the tongue.

FIG. 14 is an enlarged fragmentary view showing how a tooth is moved by applying force against its crown to move the tooth towards the tongue about the tip of its root as an axis.

FIG. 15 is an enlarged side view of a tooth holding a band presenting a bracket of a modified construction, suitable in the practice of this invention, in place of the item shown in FIG. 7.

FIG. 16 is a perspective view of the bracket part included in the assembly shown in FIG. 15.

In the drawing, the numeral 15 designates generally the upper teeth of a mouth, equipped with a rigid arch wire 16 which is fixed in position by tie wires 17 which hold it tightly within the channel 18 of a bracket 19 presented on each band 20 which is on selected teeth not to be moved in this treatment. A similar bracketpresenting band is provided on each tooth which is to be rotated about the arch wire 16. These are indicated by the numerals 21', 22', and 23' which are on the teeth 21, 22, and 23 respectively. Here, the tie wires 17 are just sufiiciently loose on the arch wire, to permit such rotation. The force-exerting elements shown in FIGS. 3-5, can be formed by the orthodontist from stock pieces of the construction shown in FIG. 2, by cutting off the L-shaped spring fingers not needed for the particular installation, or he may be furnished all the forms as stock pieces. These are of resilient material so the fingers can be flexed. Each such element comprises in the embodiments shown, a split sleeve 24, to engage a little more than of the arch wire 16, and capable of being snapped thereon, whereupon they are turnable, so after the finger 25 is flexed from a mere contact relation with the tooth it is against, by changing the angle A to angle B, the element is fixed to the arch wire by means of its set screw 26. The smaller said angle B is made, the greater is the force exerted by the finger against what it presses, and hence such pressure is adjustable. The spring fingers of the fitting 27, are denoted respectively by the numerals 25, 29, 30, and 31, and such numerical designations are repeated where they occur in the fittings 32-34. All spring fingers are cantilevers. The bracket form preferably used as shown in FIG. 7, includes the wings 36, 36', so as to make the channels 37, 37'.

In FIG. 8, the fittings 32, 32' and 32" are identical, yet each is arranged to accomplish a different result in the examples of use illustrated. The stressed spring finger 25 of the fitting 32, presses against the upper part of the band 22' which is on the tooth 22, that requires as shown in FIG. 9, to have its root moved in the direction D. This shift is accomplished because the force C exerted by said finger, causes the tooth to be urged clockwise about the arch wire 16 as an axis. The spring finger 25 of the fitting 32', acts as shown in FIG. 14, against the lower portion of the tooth 38 in the direction L, thereby causing the tooth to be shifted inwardly towards the tongue about its root tip as an axis. The spring finger 25 of the fitting 32 as shown in FIG. 12, acts against the back face of the wing 36' of the bracket on the band 23' mounted on the tooth 23, thereby exerting a force in the direction E, to turn the tooth clockwise about the arch wire 16 as an axis, and so its root is moved in the direction F. In FIG. 13, the fitting 34 is arranged that its spring finger 25 acts against the wing 36 in the direction H, and its spring finger 31, acts against the lower part of the band on the tooth 40, in the direction G, such forces urging the tooth to be rotated counterwise about the arch wire 16 as an axis whereby it is straightened; the turning forces caused by the action of said spring fingers 25 and 31, being cumulative. At frequent examinations to view the results, the orthodontist can adjust each of the elements and their spring fingers, to exert the required stress, by proper bending of the fingers with or without arcual shift of the sleeves on the arch wire.

it is evident that any of the fittings having a plurality of spring fingers can be used to act on two adjacent teeth, by bending the fingers so that one acts on the one tooth and the other on the tooth adjacent, or the second tooth from it. It is also evident that the fingers may be of different dimensions and lever shapes, which may include L-shapes as mentioned, V-shapes and U- shapes as shown in FIG. 6, and the horizontal arm of a finger may be long enough and properly shaped to act against two teeth, their bands or bracket wings, all of which is believed to be readily understood without the need of further illustration. A special adaptation is shown in FIG. 6, where the fitting 35 has one of its fingers bent into a U-shape as shown at 30'; the distal end section which is across the axis of the sleeve 24, being formed with a crimp 40 near distal end, which is adapted to straddle and press against the arch wire 16, thus serving in lieu of a tie wire to aid holding said wire in place. The finger 25 is for acting against a tooth, a bracket or band thereon, to effect a correction in tooth position, all of which the orthodontist will readily understand without further explanation.

It is intended that the arch wire shall be deemed rigid if it is stiff enough to avoid the force reactions thereon to cause any deformations therein. A recommended material therefor is stainless steel. The spring fingers of the sleeve fittings have been shown to be adapted to exert lateral push and pull forces on teeth. The recommended material therefor is also stainless steel.

Another form of bracket suitable for use in the systems illustrated herein, is that shown in FIG. 15, for it is found to eliminate the need of tie wires, and offers the channel 41, for the distal end of the spring fingers which are incident of the present invention. This bracket 42 is a piece shaped of strip material, to offer a bight channel 43 for a locking pin 44. This bracket is welded onto the periphery of a metal band 45 which is tightly fitted onto a tooth 46 in usual manner; the numerals 47 denoting the welding fins. After the arch wire 16 is set into the channel 41, the pin 44, of L-form, is inserted in the bight channel 43, and the end of the pin is bent over as at 44, to maintain the assembly.

This invention is capable of numerous forms and various applications without departing from the essential features herein disclosed. It is therefore intended and desired that the embodiments of the practices shown herein shall be deemed merely illustrative and not restrictive, and that the patent shall cover all patentable novelty herein set forth; reference being had to the following claims rather than to the specific showings and description herein, to indicate the scope of this invention.
