Important: Please read the entire manual
before installing the Quick Release TM Arch Bar Kit. (All
parts need to be sterilized “autoclavable”).
General Warnings, Precautions, and Contraindications: Persons unable to remove the
Release Bars due to a physical limitation and/or persons without adequate
assistance in the removal of Release Bars
- 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 fixation.
Sterilization: Kit contents are sold non-sterile and may be autoclaved
or sterile gassed.
Description of Device: The device is
composed of four different components, [Adjustable Loop arch bar –two flexible
Release Bars (rip cords) – two Release Bar End Gaskets - Erich arch bar] which
are installed with ligature wire. The
installed device provides temporary jaw immobilization. The
device incorporates an emergency release mechanism as a safety feature.
Installation Instructions:
Size
and pre-form the arch bars to fit dental arches. As customary alter smooth arch
bar ends after sizing. [
For improved
patient access to the Release Bar handles, it is highly recommended to affix
the Adjustable Loop Arch Bar to the maxilla
Size
Release Bars by inserting each into the Adjustable Loop arch bar channels from
desired anterior location and thread to most posterior end of Adjustable Loop
arch bar on respective right and left sides. Cut inserted Release Bars off, two
or three millimeters, past last posterior loop segment. Remove Release Bars
from arch bar channel and alter ends smooth.
(RELEASE BAR IS FLEXIBLE FOR
EASE OF INSERTION THROUGH
Note: If loop channel has a hard bend (i.e. going around a
cuspid) lightly bending flexible Release Bars, to the shape of formed
arch bar, aids in insertion of Release Bar at initial and final placement.
If bending of Release Bar is needed, keep the handle of Release
Bar in the downward position to the relationship of arch bar so Release Bar
handles remain fairly flush to surface of tooth following completion of all
wiring.
Make
note of the positioning of each Release Bar in relation to the arch bar, prior
to removal from loop channel, to insure proper replacement of Release Bars.
Place
Release Bar 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. (FIGURE 2)
Wire
arch bars to the dental arches the adjustable loop segments, 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. (FIGURE 3)
If
wired to the mandible, the adjustable loops will project upward, toward
occlusal plane,
(Scallop edge facing upward toward occlusal
plane).
Note:
While wiring Adjustable Loop arch bar to dental arch, keep all ligature wire
twists (wire rosettes) opposite the occlusal table and away from buccal or
facial portion of Adjustable Loop arch bar to eliminate any possible
interference to the release mechanism.
(Keep wire
rosettes away from the arch bar to opposing arch bar ligature wiring).
After wiring arch
bars to dental arch replace Release Bars within
Adjustable Loop arch bar ‘loop channel’ and into End Gasket.
To bring into intermaxillary
fixation,
ligature wires are first supported on Adjustable Loop arch bar loop segment and
passed between Release Bar (rip cord) and Adjustable Loop Arch Bar buccal
surface on both sides of loop segment. Boxing can be employed as in figure 4.
Wire to opposing Erich arch bar tab and tighten
the ligature wire. Keep all ligature
wire twists (wire rosettes) toward Erich arch bar and away from flexible
Release Bar. After ligature wires are tightened, (figure 4 - ARROW)
pull ligature wires supported on Adjustable Loop arch bar loop segment
forward or toward occlusal plane, away from any wire rosettes, to ensure arch
bar to opposing arch bar ligature wiring is tight.
After
wiring is complete, grasp handle of flexible Release Bar and pull forward
slightly and then back into position to ensure Release Bar is functional. If too much resistance is present, reduce
tension on ligatures until Release Bar is able to move.
(Do not
worry about over tightening ligatures prior to checking Release Bar mobility
--- you can get these ligature wires extremely tight and the release will
function, yet do check for slight mobility).
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.
Important Patient Instruction: If the patient removes the Release Bars,
thus activating the release mechanism feature, the ligature wires holding the
arches together will be released into the oral cavity and will need to be
immediately removed by patient.
The patient will need to return to the doctor for rewiring of the
Release Bars.
Light elastic
traction - Bring elastic
band into a loop segment “aperture” on Adjustable Loop arch bar and around the
opposing Erich arch bar tab to employ light elastic traction.
Note:
Warning: Utilizing elastic bands arch bar to arch bar discount the
safety release feature.
Note: Patient is to be instructed not to manipulate or bend
flexible Release Bars during appliance use, as excessive manipulation could
damage Release Bars.
