Dental Braces
(Orthodontics)
Why do people need dental braces?
Dental braces are used to straighten
crooked teeth, align upper and lower jaws, improve the aesthetics
of smiles and faces, and relieve pressure on temporomandibular
joints. Orthodontics refers to the use of devices to move teeth
or underlying bone.
Teeth can be moved at any age. "Ideal" results can be
achieved in most children but only in a small percentage of adults.
This is because in children both the bone around the teeth (alveolar
process) and the jaw bones can be molded by braces as the child
is growing. In adults the jaw bones can be altered only by surgery.
Therefore, it is recommended that orthodontic intervention be
considered as soon as a problem in teeth alignment is noticed
by the child, parent, or dentist.
The ideal age for starting orthodontic treatment ranges from 3
to 12. In children, the goal of orthodontic treatment is not only
to create straight well-aligned teeth, but also to improve the
facial profile that will remain stable throughout adolescence
and adulthood. Orthodontic treatment in adults is more difficult.
Those who undergo treatment should be aware that they will probably
need to wear a retainer at night the rest of their lives if they
want to maintain the results of the treatment.
Sometimes braces are used as the end treatment of temporomandibular
joint (TMJ) therapy. Problems of TMJ are usually aggravated by
the lower jaw being positioned too far back so that the blood
vessels and nerves of the TMJ are compressed. TMJ splint therapy
is used initially to relieve this pressure and to reduce pain.
The splint actually moves the lower jaw to a new position. If
the patient does not want to wear a splint for the rest of his/her
life, then the teeth must be moved to stabilize the jaws in this
new position. This movement of teeth can be done by dental braces.
Orthodontic appliances can also be used to help a child overcome
the infantile habits of sucking a thumb, finger, or pacifier.
Sucking habits are usually not a major concern unless they are
perpetuated after age 6 or 7, when the permanent incisors and
molars start to erupt into the mouth. If these habits persist
in the presence of permanent teeth, then permanent changes in
the teeth and jaw bones are produced. Sucking habits can create
open bites where the upper and lower front teeth do not meet.
They can lead to protrusive teeth and upper lips and protrusive-
looking
faces in general. Excessive sucking causes the muscles of the
cheeks to constrict the upper dental arch. This contributes to
a loss of space for the tongue to rest, and subsequent abnormal
tongue posture or tongue thrusting habits. Sucking also causes
the maxillary sinuses to constrict, which aggravates breathing
and allergy problems.
A variety of devices is used for different age groups. Some devices
are only for infants to treat congenital defects such as cleft
palates. Others are utilized only on baby teeth or in children
who have both baby and permanent teeth (mixed dentition). Still
others are employed when all the permanent teeth have erupted.
Some orthodontic appliances used in children are actually orthopedic
devices that redirect jaw bone growth.
