Quick Release™ Arch Bar Kit User Manual

U.S. Patent No. 5,842,856 Other patents pending.

Important: Please read the entire manual before installing the Quick Release TM Arch Bar Kit. All parts need to be sterilized.

General Warnings, Precautions, and Contraindications: persons unable to remove the Release Bars due to a physical limitation do not indicate The Quick Release TM Arch Bar Kit for use.

Indications for Use: Casey Surgical Quick Release TM Arch Bar Kit is indicated for use in intermaxillary and maxillo-mandibular fixation.

Description of Device: The device is made of four different components, which are installed, by an oral surgeon or dentist along with ligature wires. The installed device provides temporary jaw immobilization. The device incorporates a release mechanism as a safety feature.

Installation Instructions: Size the arch bars to fit dental arches. For improved patient access to the Release Bars, affix the Adjustable Loop Arch Bar to the maxilla. File arch bar ends smooth after sizing. Size Release Bars by inserting each into the Adjustable Loop Arch Bar channels from desired anterior location and thread to most posterior end of arch bar. Cut inserted Release Bars off, two or three millimeters past last posterior loop segment. Remove Release Bars from arch bar channel and file ends smooth.

Note: Make note of positioning of Release Bars prior to removal to insure proper replacement of Release Bars. (Lightly bending Release Bars to form of arch bar aids in insertion of Release Bar at final placement.) (Release Bar is extremely flexible for inserting within loop channel).

Place tissue protective end Gaskets within most posterior loop segments. Insert Gasket tail into mesial portion of end loop and pull tail through loop until it is fully engaged within loop segment. Following are photo shows placement and seating of the gasket.

Wire arch bars to the dental arches. The adjustable loops, on the Adjustable Loop Arch Bar, are to be projected downward, toward occlusal plane, (scallop edge facing downward toward occlusal plane), when wired to the maxilla.

If wired to the mandible, the adjustable loops will project upward, toward occlusal plane, (scallop edge facing upward toward occlusal plane).

The tabs on the opposing Erich Arch Bar are to be projected downward, away from occlusal plane, (scallop edge facing away from occlusal plane), if wired to the mandible.

If the opposing Erich Arch Bar is wired to the maxilla the tabs will project upward away from occlusal plane, (scallop edge facing away from occlusal plane).

Note: After wiring Adjustable Loop arch bar, keep all ligature wire rosettes opposite the occlusal table and away from buccal or facial portion of arch bar to eliminate any possible interference to the wiring of ligatures behind Release Bar to opposing arch bar. Replace Release Bars within loop channel and into Gasket. If loop channel has a hard bend (i.e. going around a cuspid), pre-bend Release Bar accordingly prior to insertion into channel.

To bring into intermaxillary fixation, ligature wires are supported on adjustable loop tab and passed between Release Bar and Erich Arch Bar on both sides of loop tab.

Next, wire to opposing arch bar tab and tighten the ligature wire. Keep all ligature twist toward opposing arch bar and away from Release Bar. After ligature wires are tightened, (figure 6) pull wires on looped bar forward or toward occlusal plane away from wire rosettes, to insure ligatures are tight.

After wiring is complete, grasp handle of Release Bar and pull forward slightly and then back into position (inserted within Gasket) to ensure Release Bar is functional. If too much resistance is present, reduce tension on ligatures until Release Bar is mobile.
If the patient removes the Release Bars, thus activating the release mechanism feature, the ligature wires will be released into the oral cavity.

(In case of an emergency, the patient should be instructed to grasp the Release Bars by the handles and firmly pull from mouth releasing their fixation).

Light elastic traction may be employed by bringing elastics into the loop segment “aperture” of arch bar and to the opposing arch bar tabs.

Note: Loop segments on arch bar must first be manipulated open by placing a woodson instrument into loop aperture and torque loop slightly open to allow the band placement within aperture.

Warning: Utilizing elastic bands arch bar to arch bar could discount the safety release feature.

Note: Patient is to be instructed not to manipulate or bend Release Bars during appliance use, as excessive manipulation could damage Release Bars.
