Pearls of the Pacific
on to surgical wires accurately, securely,
and quickly and often without
removing the wires. This helps
prevent unwanted tooth movement
from occurring after scans or
impressions are taken for surgical
splints and templates. The hooks are
made of a relatively stiff, dimensionally
stable nickel titanium alloy and
machined very accurately. Compression
hooks are held in place by
friction and will not slide, shift, or
twist on the archwire (Figure 2). A
special application tool that comes
with the hooks temporarily deforms
them enough to fit on the archwire
without exceeding the yield point
(Figure 3). Once placed on the
wire, they cannot come loose or be
removed (Figures 4 and 5). Alternatively,
surgical archwires prepared
with soldered hooks (Figure 6) must
be removed from the mouth for
hook application and can be damaged
or distorted in the process.
Small errors in soldering technique
can cause annealing of the wire, resulting
in unwanted changes in the
shape and temper of the wire and
altering the mechanical properties
needed for proper stabilization of
tooth position during and after surgery
(Figure 7). With surgical wires
prepared with compression hooks,
the advantages in accuracy, patient
comfort, and hygiene are implicit
(Figure 8). The hooks come in a few
different lengths and sizes (depending
on your archwire sizes) and are
handy for a quick application for
intraoral elastics. The longest hooks
should be used for surgical wires.
Watch and follow the brief instructional
video before using for the first
time. Your surgeon will love having
these in place during orthognathic
surgery!

Figure 7. Potential pitfall of soldering wires: placing
soldered hooks on surgical wires can be technically
challenging and cause annealed spots, which then become
distorted when intermaxillary fixation is applied
Figure 6. Correctly positioned and applied soldered
hooks
Figure 8. Compression hooks have advantages when
compared with soldered or crimped hooks before
surgery: archwire crimping or distortion is eliminated,
and easier, more precise placement (without archwire
removal if necessary) can be expected
