» Orthodontic Appliances
Orthodontic Appliances a device, either fixed to
the teeth or removable, that applies force to the teeth and their supporting
structures to produce changes in their relationship to each other and to
control their growth and development. Anything your orthodontist attaches to
your teeth that moves your teeth or changes the shape of your jaw.
Habit Breaking Appliances
Thumb Sucking Habit Breaking Appliance
Sucking is a natural reflex that relaxes and comforts babies and toddlers.
Children should cease thumb sucking when the permanent front teeth are ready
to erupt. Typically, children stop between the ages of 2 and 4 years. Thumb
sucking that persists beyond the eruption of permanent teeth can cause
improper growth of the mouth and malalignment of the teeth. A more permanent
solution to thumb sucking is an appliance called a fixed palatal crib
The appliance is cemented on the upper six year permanent molars and is
positioned behind the upper front teeth on the roof of the mouth. The crib
consists of semicircular stainless steel wires that are fastened to molars
using steel molar bands. The stainless steel wires fit behind the childs
upper front teeth, and they are barely visible, if at all. This appliance
does not cause any discomfort and is not affected by eating. It serves as a
reminder to the child that the thumb is not suppose to be in his mouth. The
crib usually stops the habit of thumb sucking within weeks or months.
Tongue Thrust Habit Breaking Appliance
Tongue thrusting, simply defined, is the habit of placing the tongue in the
wrong position during swallowing, either too far forward or to the sides. It
is estimated that every 24 hours you swallow a total of 1,200 to 2,000
times, with about four pounds of pressure per swallow. This constant
pressure of the tongue will force the teeth and arches out of alignment.
Besides the pressure exerted while swallowing, nervous thrusting also pushes
the tongue against the teeth while it is at rest. This is an involuntary,
subconscious habit that is difficult to correct. A tongue thrusting
appliance is made for the patient that is permanently cemented in place. It
is necessary to correct this habit prior to doing orthodontic treatment on a
patient. If this habit is not corrected, the teeth will relapse after
orthodontics due to the tongue pushing against the teeth when swallowing.
