Definitions

  • While devices of the foregoing type have certain recognized advantages over other devices, they lack versatility in that an optimum control of the forces on an entire dental arch or certain teeth of an arch cannot be attained since the force applied to the inner bow is essentially a plan force in a selected direction with respect to the plane of the outer bow.
  • an orthodontic device which forms a part of an orthopedic force-control head gear for applying both tractional and torsional forces to selected teeth.
  • the device comprises an inner bow having spaced ends connectable to buccal attachments on posterior teeth, an outer bow having spaced ends connectable to the head gear and means connecting the inner bow to the outer bow at the center of each so that the inner bow is pivoted with respect to the outer bow.
  • resilient means can form part of the connecting means for interconnecting the inner and outer bows for applying a torsional force to the posterior teeth when the ends of the inner bow are connected to the buccal attachments and the ends of the outer bow are connected to the head gear.
  • the orthodontic device includes an inner bow lying in a first plane and having spaced ends connectable to buccal attachments on posterior teeth.
  • the inner bow includes means for attaching the inner bow at the center thereof to a connector comprising first and second spaced S-shaped segments extending from the attaching means and first and second arcuate segments extending respectively from the S-shaped segments to the ends, the arcuate segments being curved to extend around the teeth so that the ends are connectable to the buccal attachments, the S-shaped segments providing means for distorting the inner bow so that the arcuate segments do not lie in a common plane to apply unequal torque to the buccal attachments.
  • the S-shaped segments make it possible to spread one or both legs of the inner bow in or out to apply an inwardly or outwardly pressure on the teeth to correct cross bite.
  • the connector is rotatably mounted about an axis on the outer bow, which normally lies in a second plane.
  • the axis is illustrated as being at the intersection of the first and second planes and has ends extending outwardly from the center of the outer bow.
  • there is means on the connector intermediate the ends thereof for detachably connecting the inner bow to the outer bow and first and second coil springs around the other bow at opposite ends of the connector, each spring having one end -the inner bow.
  • an anterior clip having a first end attachable to the connector can be provided at the center thereof so that the clip extends in the direction of the ends of the inner bow and intermediate thereof and has a second end for attachment to the center' of an arch wire attached to the teeth.
  • the foregoing described apparatus provides a versatility heretofore unknown.
  • the device With the anterior clip removed, the device can be used to either extend or depress posterior teeth by means of the torsional forces applied through the spring.
  • the torsional forces applied by the spring can be used to extend both posterior and anterior teeth or to depress both posterior and anterior teeth depending on the orientation of the device on the patient, as described more fully below.
  • the device can be used to extend the posterior teeth and depress the anterior teeth or conversely to depress the posterior teeth and extend the anterior teeth.
  • a torsional force can be applied through the anterior clip to the anterior teeth to cause either an inward or outward movement thereof.
  • anterior bow as described above, can be used to cant the posterior teeth or to widen or narrow the arch as will be more fully described below.
  • FIG. 1 is a side elevation showing the orthodontic device of this invention in position on a patient
  • FIG. 2 is an enlarged side elevation showing the connection of the inner bow of the invention to a tooth arch;
  • FIG. 3 is a bottom plan as viewed in the direction of arrow 3 of FIG. 2 showing further details of the invention',
  • FIG. 4 is a section taken on line 4-4 of FIG. 3 showing the connection of the inner bow and the anterior clip
  • FIG. 5 is a section taken on line 5-5 of FIG. 4 showing further details of the inner bow attachment.
  • the components of the invention comprise, briefly, an inner bow 10, an outer bow 12, a connector 14 between the inner and outer bows, a spring 16 for producing a torque force between the outer and inner bows, and a neck or cervical band 18 for applying traction forces to the ends of the outer bow, each of which will be described in detail.
  • an inner bow 10 an outer bow 12
  • a connector 14 between the inner and outer bows
  • a spring 16 for producing a torque force between the outer and inner bows
  • a neck or cervical band 18 for applying traction forces to the ends of the outer bow
  • lnner bow is arch shaped, having arcuate segments 19 with free ends which slideably telescope within buccal tubes 20. Collars 22, which may be welded or soldered to the bow, providing abutments for applying rearward forces on the front ends of the buccal tubes.
  • the central portion of bow 10 is provided with a U-shaped tongue 24, the ends of the legs of which join lateral U-shaped bends 26, the latter being joined to the arch wire by U- shaped bend 28 so that an S-shaped configuration is provided between the tongue 21 and each arcuate segment 10. All parts of the arch wire normally lie in a plane but portions may be distorted out of the plane, when desired, as will subsequently appear.
  • Connector 14 is provided with a slot 30 which slideably receives tongue 24, the connector abutting bends 26 for applying a rearward force to the inner bow.
  • An aperture 32 slideably receives a rod 34 having a hook 36 at the inner end thereof, the purpose of which will be subsequently described.
  • a transverse aperture 38 extends throuh the connector which rotatably receives the central portion of outer bow 12.
  • Spring 16 comprises two coil springs 40, the outer ends of which are secured to the outer bow by welds or solder, their inner ends being connected together by a bridge stop wire 42 which may engage the connector in two alternate positions as will subsequently be described.
  • spring 16 is a torsion spring for applying torque from the outer bow to the connector and the inner bow secured to the latter.
  • the ends 43 of the outer bow are provided with hooks 44 for securing it to neck band 18.
  • Neck band 18 is formed of resilient material, such as rubber, which carries a buckle 46 at each end thereof, the buckles preferably being of the conventional slideably adjustable type which may be positioned at desired positions on the band to thereby adjust band tension. As will be apparent, the buckles engage hooks 44 on the outer bow. It is understood that it is not necessary for the entire neck band 18 to be made of resilient material but only the end portions thereof need be so made or the neck band could be connected to outer bow 12 by resilient means, such as rubber bands, which would replace buckles 46 as is well understood by one skilled in the art.
  • the inner bow is inserted in the buccal tubes 20.
  • the connector is attached to the inner bow by sliding slot 30 over tongue 24.
  • the connector is oriented so that bridge 42 of spring 16 abuts the bottom surface of the connector and the outer bow 12 is in an approximate horizontal position and extending outwardly from the inner bow at approximately 180 thereto.
  • the outer bow then is rotated downwardly and rearwardly about 160 to 180 to the position shown in FIG. 1 and its hooks are attached to the neck band buckles 46. Assuming that anterior clip 34 is not in place and is not attached to tooth bridge wire 48, forces are applied soley to buccal tubes 20.
  • torsion spring bridge wire 42 will now be at the top of the connector.
  • Outer bow 12 is rotated upwardly and rearwardly and attached to neck band 18, as before. Now a downward or extending force is applied to the posterior teeth.
  • anterior clip 34 is used and positioned in so that hook 36 engages the gingival side of arch wire 19, hook 36 will normally apply a downward force to arch wire 48 causing all teeth attached thereto to be extended.
  • the clip is turned so that hook 30 engages the insical side of the arch wire so that an upward or depressive force will be applied to the anterior teeth while spring 16 still applies a downward or extending force to the posterior teeth.
  • a high pull head gear would be used.
  • the device can be used on the lower teeth as will be apparent to one skilled in the art.
  • portions or all of wire assembly 24, 26, 28 may be axially twisted away from the plane ofinner bow 10. Since tongue 24 is non-rotatable in slot 30, this applies a torque to the inner bow around its longitudinal central axis, effecting unequal torque forces on the buccal tubes.
  • the spacing arcuate segments 19 can effect the direction of rearward movement of the posterior teeth to which buccal tubes 20 are attached.
  • the novel S-shaped connection between tongue 24 and arcuate segments 19 facilitates the bending ortwisting of the arcuate wires to accomplish such result as well as the canting of the inner bow to provide unequal forces as described above or to apply either an inward or outward force on one or both sides by bending the ends of the inner bow inwardly or outwardly, respectively.
  • the traction force on the inner bow may be adjusted by moving the buckles on the neck band.
  • the torque forces on the inner bow may be varied by choice of the spring constant of spring 16. For example, if greater torque is desired, a spring of greater spring constant is employed.
  • the inner bow may be constructed to one standard length and the sleeves thereon which abut the buccal tubes may be secured in desired initial position. As the teeth move back, for example, other sleeves may be added to the inner how.
  • the construction of the connector is also such that no irritating contact occurs at the corners of the mouth, which has previously occurred with some connectors.
  • An orthodontic device for use with a head gear for applying both tractional and torsional forces to selected teeth, said device comprising:
  • an inner bow lying substantially in a first plane and having spaced ends connectable to buccal attachments on posterior teeth;
  • resilient force-applying means connected between said inner and outer bows applying a torsional force about said axis to said inner bow and to the posterior teeth when the ends of the inner bow are connected to the buccal attachments and the ends of the outer bow are connected to the head gear.
