Definitions

  • One object of the invention is to provide a device of this character which shall include a body portion for attachment to a tooth band and constructed to permit the arch-bow or wire to be applied thereto in approximately the plane of the dental arch, in combination with removable clamping means for either positively clamping the wire in the body portion against movement relative thereto or to hold the wire against lateral displacement from the body portion and free for movement longitudinally of itself.
  • a device will to a great extent eliminate the necessity for the use of ligatures because the arch-bow can be accurately bent for attaching to particular misplaced teeth and then easily inserted in the locking device.
  • the positive clamping of the arch wire in the lock eliminates the necessity for soldering of stops on the arch wire at the anchor teeth since the lock may be applied to an anchor tooth and the archbow can be adjusted to the desired position by sliding through the look, after which the wire can be positively clamped in the lock.
  • Another object of the invention is to provide an orthodontia lock of this character wherein the arch wire may be attached to the lock in such a way as to make possible the exertion of pressure or tension on a tooth in any direction, whereby complete control of rotation of molars and distal or mesial tipping of teeth may be easily accomplished.
  • a further object is to provide an orthodontia lock of the general character described especially adapted for use with arch wire of rectangular cross-section so that the wire can be positively clamped in the look at all four sides of the wire to prevent rotation of the wire, whereby a tooth may be rotated or tipped in various directions without the necessity for springs or other extraneous pressure; although the invention contemplates a lock which may be used with arch wire of any cross-section shape.
  • Another and highly important object of the invention is to provide such a lock which shall be of minimum size consistent with the required strength so as to cause a minimum of irritation in the mouth, and thus to form the. lock of simply a body portion having a slot to receive the arch wire, and a clamping screw plug for holding the Wire in said slot.
  • Figure l is a plan view of a dental arch having the tool for operating the clamping screw plug.
  • Figure 5 is a perspective viewof the lock showing the body portion and the clamping plug in separated relation.
  • Figure 6 is a front elevation of a form 1 of the lock especially adapted for use on molar teeth.
  • Figure 7 is a horizontal sectional View through several teeth having'lock's attached thereto showing the manner of vusing the locks, and,
  • Figure 8 is. a'front elevation of several teeth with locks attached thereto illustrating the adaptability of the lock to difficult orthodontic operations.
  • the ortho-dontia lock comprises a body portion I which is preferably in the 7 1 opening 3 extending transverse of the slot'and of the slot.
  • Theslot 2 is preferably rectangular andof a width to nicely receive anarch wire 4 that'is approximately square in crosssection.
  • a screw plug 5 is provided to fit the opening 3; and the 'plug is adjustable in the opening so as to either positively clamp the arch wire against any move:
  • theplug 5 has a centralopening or recess 6 to cooperate with a tool 'lfo'rhane dling and manipulating the plug.
  • the tool fl. has
  • the plug can be attached and detache from the tool andcarried to and from the mouthof the patientandrscrewed or removed from the body portion or" the lock, easily,
  • the plug and tool "I may be made of magnetic material, and one thereof may be imagnetizedto make the connection of. the tool to the plug more positive. 7

  • the locks used on the 'molar teeth have somewhat broader bases on the blocks than the. locks'u'sedon the anterior teeth, 1.
