Abstract

An apparatus and method for fixing a patient's jaw by using arcuate arch bars which are fastened to both the upper and lower teeth using a plurality of zip ties. The arch bars are provided with bores and zip ties are passed through these bores and fastened to the patient's teeth. Each arch bar is provided with interarch receptacles which receive and engage a zip tie. The receptacles are rotatable and are generally aligned between the upper and lower arch bars. Additional zip ties with opposed teeth are passed through the upper and lower pairs of arch bar receptacles and tightened to fix the lower jar to the upper jaw.

Claims (16)

1. An apparatus for fastening a patient's upper jaw and lower jaw together comprising:

an upper arch bar including a plurality of lateral bores;

a lower arch bar including a plurality of lateral bores;

at least one rotatable upper interarch receptacle;

at least one rotatable lower interarch receptacle;

a plurality of arch bar fasteners for attaching the upper arch bar to the upper jaw and the lower arch bar to the lower jaw; and

at least one interarch fastener for fastening the at least one rotatable upper interarch receptacle and the at least one rotatable lower arch receptacle, together;

wherein the at least one rotatable upper interarch receptacle and the at least one rotatable lower interarch receptacle freely rotate to substantially align when fastened together;

wherein each of the plurality of arch bar fasteners is secured through two lateral bores in the upper arch bar, or through two lateral bores in the lower arch bar;

wherein one or more fasteners of the plurality of arch bar fasteners comprises a strap having a length and ratchet serrations extending substantially along the length of the strap from a first end thereof to a second end thereof, and a ratchet attached to the second end thereof for receiving and securing the first end of the strap;

wherein the at least one interarch fastener is secured to one interarch receptacle on the upper arch bar and one interarch receptacle on the lower arch bar;

the at least one interarch fastener comprising a linear strap with the ratchet serrations, wherein both the rotatable upper interarch receptacle and the rotatable lower interarch receptacle incorporate a ratchet for receiving and securing the ratchet serrations on the interarch fastener;

the linear strap of the at least one interarch fastener further comprising:

a front side including first and second ratchet engaging surfaces disposed proximate opposing ends of the strap, for engaging ratchet portions of the rotatable upper interarch receptacle and the rotatable lower interarch receptacle, the first ratchet engaging surface including ratchet serrations oriented in a first direction and the second ratchet engaging surface including ratchet serrations oriented in a second direction, opposite the first direction; and

a back side having a smooth surface.

2. The apparatus of claim 1 wherein the at least one interarch fastener is an opposed cable tie.
