The maxillomandibular fixation device broadly includes a strip of material for positioning around an individual's teeth; an arch bar positioned against the teeth; and a clamping assembly for clamping the material to the arch bar. The material may include a single length of material or may be multiple lengths of shorter material. The clamping assembly may include a lever portion and a hook portion or may be a single slidable side clamp. ## Claims ### Claim 1 A maxillomandibular fixation device comprising: a single strip of material for positioning around multiple teeth of an individual; an arch bar, and a clamping assembly for securing the single strip of material, the clamping assembly comprising a base coupled to the arch bar, wherein the arch bar comprises a plurality of hooks configured such that the single strip of material when weaved around one or more of the multiple teeth attaches to at least some of the plurality of hooks for anchoring the arch bar against the multiple teeth, wherein the base of the clamping assembly comprises an opening extending therethrough, wherein the maxillomandibular fixation device further comprises a spool received within the opening. ### Claim 2 (depends on 1) The maxillomandibular fixation device of claim 1, wherein a first end of the spool includes one or more legs, said one or more legs defining a channel for receiving a portion of the strip of material. ### Claim 3 (depends on 1) The maxillomandibular fixation device of claim 1, wherein a second end of the spool includes a first ratcheting surface matingly received by a second ratcheting surface included within the base opening. ### Claim 4 (depends on 1) The maxillomandibular fixation device of claim 1, wherein the opening includes a ratcheting surface wholly or partially extending around a circumference thereof. ### Claim 5 (depends on 1) The maxillomandibular fixation device of claim 1, wherein the single strip of material is configured to be weaved around a tooth of the multiple teeth and cross a gap between the tooth and an adjacent tooth at least twice for attaching to one of the plurality of hooks. ### Claim 6 The maxillomandibular fixation device of 1, wherein the arch bar further comprises an arm extending downwardly therefrom and configured to be placed in edentulous areas. ### Claim 7 (depends on 6) The maxillomandibular fixation device of claim 6, wherein the arm comprises an aperture for receiving fastening means for fastening the arm to an alveolar bone. ### Claim 8 (depends on 7) The maxillomandibular fixation device of claim 7, wherein the fastening means comprises a bone screw. ### Claim 9 (depends on 1) The maxillomandibular fixation device of claim 1, wherein the strip of material is selected from an aramid, an ultra high-density polyethylene and a metal. ### Claim 10 (depends on 9) The maxillomandibular fixation device of claim 9, wherein the aramid is poly-para-phenylene terephthalamide. ### Claim 11 (depends on 9) The maxillomandibular fixation device of claim 9, wherein the metal is stainless steel. ### Claim 12 (depends on 1) The maxillomandibular fixation device of claim 1, wherein the single strip of material is 45 cm to 50 cm in length. ### Claim 13 (depends on 1) The maxillomandibular fixation device of claim 1, wherein the single strip of material is 3 cm to 4 cm in length. ### Claim 14 (depends on 1) The maxillomandibular fixation device of claim 1, wherein the clamping assembly is constructed of stainless steel or titanium. ### Claim 15 A maxillomandibular fixation device comprising: a single strip of material for positioning around multiple teeth of an individual; an arch bar; and a clamping assembly comprising a base coupled to the arch bar, wherein the arch bar comprises a plurality of hooks configured such that the single strip of material when weaved around one or more of the multiple teeth attaches to at least some of the plurality of hooks for anchoring the arch bar against the multiple teeth, and the base further comprises a laterally extending U-shaped projection defining a U-shaped space. ### Claim 16 (depends on 15) The maxillomandibular fixation device of claim 15, wherein the arch bar comprises a hook that matingly receives the U-shaped space in a snap fit relationship.
