Dr.
Orr is always looking for ways to increase the efficiency and
comfort of braces for our patients. There have been many types
of self-ligating brackets developed over the years. However,
there is one now that looks well-designed enough to use on our
patients. We are placing self-ligating or self-locking brackets
called Carriere on some of our patients. This bracket was designed
by Dr. Carriere of Spain and is being manufactured by Class I
Orthodonitcs, a leading orthodontic supply company. These brackets
have only recently been made available to the orthodontic profession.
This
locking system bracket eliminates the need for steel ligature
ties and/or plastic ties that distort and collect plaque.
We
have tried all types of lower retainers over the years, because
long-term retention of the lower teeth after orthodontic correction
with braces is the key to preventing relapse and crowding of
the lower teeth. Although the fixed banded lower anterior retainer
is difficult to make and requires an expensive laboratory procedure,
we have found it to be the best for durability, ease of care,
and it needs minimal repairs. It also does not get lost!!
The fixed banded lower retainer is "an oldie, but goodie".
Many
of the archwires now used for orthodontic treatment were developed
from metals originally designed for the antennae that could be
rolled into coils for the spacecraft used in the moon walk by
astronauts in the 1960's. These metals have been constantly upgraded
for use in orthodontic wires and also in eyeglass frames. We
are currently using a fifth generation of archwire design, and
they reduce the amount of soreness that develops when moving
teeth -- parents may remember some of this soreness!! These wires
also sometimes allow longer time intervals between adjustments
because of their gentle and longer-lasting pressures.
