Orthodontics:Orthodontics
is the branch of dentistry that specializes in the
diagnosis, prevention and treatment of dental and facial
irregularities.
The
technical term for these problems is "malocclusion,"
which means "bad bite." The practice of orthodontics
requires professional skill in the design, application
and control of corrective appliances, such as braces, to
bring teeth, lips and jaws into proper alignment and to
achieve facial balance.
To treat the
malocclusion two type of treatment are used :
1.Removable
Appliances
2Fixed
Orthodontic Braces
Two-Phase
Orthodontics (early interceptive treatment)
During early age children exhibit
signs of crowding of teeth during there growth period. Jaws may grow too much or
too little. Sometimes they may be much too narrow or wide. These children (over
the age of 4) may be excellent candidates for early orthodontic care.
Because children are
growing at a rapid rate, appliances can be utilized to direct
growth to improve the jaw and teeth alignment. Most often it is simply creating
enough room to have all the permanent teeth erupt without the need for
extractions. With some cases, if this early care is not provided, corrections
may involve orthognathic surgery.
Some children may have
early orthodontics with braces placed on just a few teeth, such as one molar on
each side and the front 4 teeth, we call this a 2 by 4. The goals of partial braces are front tooth
alignment and assisting in establishing a correct relationship between the upper
and lower.
Early treatment may
decrease the treatment time required for the second phase. Often, at the
end of the first-phase, the teeth are not be in their final position, this
will be accomplished during the second-phase. The primary goal of the first
phase is to develop a solid foundation for the teeth. Periodic recall appointments are
set in order to check the progression of jaw growth and permanent tooth
eruption.
Second-phase treatment
most often consists of straight-forward orthodontic therapy that will accomplish
the final alignment of the
teeth.
The major advantage of
two-phase therapy is to maximize the opportunity to guide jaw growth and tooth
eruption.
Optimizing the treatment with the correct timing of the child growth and
development is of utmost importance in these
cases.
The main disadvantage of waiting for permanent tooth eruption is a final result
that may not be functionally healthy or stable. Tooth extraction or
corrective jaw surgery (orthognathic surgery) may be required as well.
Causes of Malocclusion:
Most malocclusions are inherited, but some are acquired. Inherited problems include crowding of teeth, too much space between teeth, extra or missing teeth, and a wide variety of other irregularities of the jaws, teeth and face.
Acquired malocclusions can be caused by trauma (accidents), thumb, finger or dummy (pacifier) sucking, airway obstruction by tonsils and adenoids, dental disease or premature loss of primary (baby) or permanent teeth. Whether inherited or acquired, many of these problems affect not only alignment of the teeth but also facial development and appearance as well.
