ORTHODONTIC TRIVIA |
 |
 |
Braces aren't just for
children. The percentage of adults seeking orthodontic treatment
has increased from 17 percent in 1979 to 30-40 percent in
2001. |

What is Orthodontics? |
|
 |
| |
Orthodontics is the branch of dentistry which specializes
in the correction of malocclusion. A malocclusion
is simply a bad bite and come in many forms, however,
they can usually be divided into two different categories.
The first category is called a skeletal malocclusion.
These are caused by a bad relationship between the
sizes of the upper and lower jaws e.g. a small lower
jaw and a large upper jaw may create the appearance
of a "chinless wonder".
The other category is called a dental malocclusion
because it is caused mainly by bad positioning of
the teeth e.g. crowding. Some malocclusions are in
fact a combination between skeletal and dental problems. |

Why is Orthodontics necessary? |
|
 |
| |
Most patients seek orthodontic treatment because of the
poor appearance of the teeth and/or face caused by
the malocclusion. This may be very, important especially
in young children and teenagers where acceptance by
peers and teachers may severely affect their entire
outlook on, and approach to life.
There are also other very important reasons why one
should have orthodontic treatment. In cases which
have a lot of crowding some teeth may not be cleaned
very well following routine toothbrushing; as a consequence,
plaque, which is a white, gelatinous mixture of bacteria
and sugar-like substances, may build up on the teeth
and cause cavities or gum disease. This could seriously
affect the longevity of the teeth.
Also, cases with bad bites may develop problems in
the jaw joints (the temporomandibular joints or TMJs).
This may not be evident until the middle years of
life or later and may start as clicking sounds heard
or felt in the joints and may progress to severe pain
in the joints along with annoying headaches.
So, orthodontic treatment can be very important for
the normal development, well being and general health
of both children and adults. |

What causes Orthodontic problems? |
|
 |
| |
The root causes of many orthodontic problems are
not well understood. It has been suggested that some
of these problems are inherited e.g. a child who inherits
small jaws from one parent and large teeth from another
may have crowding of the teeth. The cause of some
other orthodontic problems, however are easily identified.
One of these is thumb and finger sucking, which is
in fact, a part of a whole group of habits which may
cause malocclusions. Also included in this group are
nail biting and tongue sucking or thrusting. The effect
of these habits on the teeth will depend on how they
are done, and how often. So one individual who sucks
his or her thumb all day long may have a severe problem,
while a child with an irregular habit may have little
or no problem.
Another obvious cause of malocclusion is mouthbreathing.
Which may be just another habit, or, as is often the
case may be caused by blocked nasal passages caused
by long lasting colds and allergies. Sometimes, the
nasal passages may be blocked by enlarged adenoids,
which are tonsillar type tissues located at the back
of the nose.
Other causes of malocclusion include cavities, gum
disease, loss of permanent teeth and early loss of
baby teeth. This shows the importance, once again,
of good toothbrushing and care of the teeth to a healthy
smile and bite. |

At what age should
Orthodontics be started? |
|
 |
| |
Orthodontics can be carried out on anyone at any
age, providing that the teeth and gums are healthy.
There are, however, some advantages to starting treatment
at an early age; for instance in cases which are the
result of poor growth of the jaws, treatment is best
undertaken during the years of growth when it may
be possible to alter the rate or direction of growth
of the jaws.
The best age to start treatment for these children
will be between the ages of seven and nine. A few
cases may be started before seven years especially
those involving habits and problems interfering with
normal function. |

How is Orthodontics accomplished? |
|
 |
| |
| Below we have outlined the basic steps involved
in accomplishing orthodontic treatment. |
| |
| Diagnostic Records
Click
for Pictures |
| |
| Before orthodontic treatment can be started
it is important to have a full understanding of
the problems that the patient has. This involves
the taking and analysis of records on the patient.
The records taken will include the following: |
- A detailed history of dental and medical
problems.
- Impressions of the teeth - these are molds
of the teeth into which plaster will be poured
to give accurate models of the teeth.
- X-rays of the teeth and skull to help identify
hidden problems.
- Pictures of the teeth and face so as to
have a visual indication of what the teeth
and gums look like at the start of treatment.
|
| |
| Treatment |
The first important decision to be made by
the orthodontist is whether or not teeth need
to be extracted to correct the orthodontic problem.
If extractions are necessary the decision is
then made on which teeth to extract. Patients
are usually sent back to their general dentist
or to an oral surgeon to have these extractions.
Appliances are then selected by the orthodontist
to move the teeth into the desired positions.
These appliances are generally called braces
by layman and consist of several components.
Removable appliances can be taken out of the
mouth by the patient and usually have a portion
made of acrylic into which the wires which move
the teeth are inserted.
All of the appliances are custom designed by
the orthodontist to do specific jobs and all
require a great deal of care by the patient.
Braces often make it difficult to remove food
and plaque from the teeth and the patients must
brush their teeth carefully many times a day.
Removable appliances must also be kept free
of plaque and debris and the orthodontist's
instructions must be followed carefully in order
to get the desired effects. |
| |
| After removal - Retention |
| After appliances are removed it is normal for
the teeth to tend to move towards their old positions.
To prevent this, retainers are given to the patients
at the time of the removal of the braces, these
retainers are usually removable or consist of
a thin wire stuck to the backs of the teeth. Retention
is usually carried out for a period of at least
one year, but the specific length of retention
will be different from case to case. |

The Results? |
|
 |
| |
The end result of orthodontic treatment is teeth
which are well aligned and appear pleasing to the
eye. In addition the lower face, the lips and the
chin should be well related to the rest of the face
so that the best possible appearance is realised.
Also, the function of the jaws, the tongue and the
cheeks should be improved so as to reduce the possibility
of joint and gum problems.
To attain the best possible results, it is important
that the patient co-operate to the greatest possible
extent. The patient must report for appointments on
time, the patient must wear all appliances and accessories
as instructed by the orthodontist and the patient
must take care to keep teeth and appliances impeccably
clean. All of these are as important for a good result
as the work that the orthodontist will do in his office. |

OPEN BITE - Click for Picture
This malocclusion (bad bite) occurs most often with the front teeth, which in this instance are unable to meet when biting on the back teeth. This kind of bad bite is mainly caused by poor oral habits that are practiced in childhood. These habits often continue into adolescence and at times into adulthood.
Such habits include:
- Finger sucking.
- Tongue sucking.
- Tongue Thrusting while swallowing.
- Poor tongue posture (tongue lying between the front teeth and sticking forward.)
- Mouth breathing
CROSSBITE - Click
for Picture This
describes when the upper and lower teeth are biting in reverse
position. For example, the lower teeth biting in front of the upper teeth. This kind
of "reverse bite" can
also occur at the sides. Crossbites mainly occur due to delayed
loss of baby teeth, which causes the permanent teeth to erupt out of position. All
types of crossbites
can adversely affect jaw function, cause gum and bone breakdown
as well as jaw joint (TMJ) disorder.
CROWDING - Click for Picture Crooked, rotated and overlapped teeth result when there is not enough space available in the jaws to comfortably hold the teeth. The main causes for crowding are:
- Genetic transmission.
- Early or even late loss of some primary teeth.
Besides being unattractive, crowded teeth are very difficult to brush and floss effectively, this in turn causes caries (cavities) as well as the build up of plaque and calculus. All these problems can cause the breakdown of the supporting gum and bone and can eventually lead to tooth loss.
SPACING - Click for Picture
Spacing between the teeth occurs as a result of:
- Small teeth or conversely relatively large jaws.
- Abnormal oral habits: finger sucking, tongue sucking etc.
- Abnormal tongue posture as well as tongue thrusting during swallowing.
spacing also occurs if a permanent tooth is extracted and is not replaced with a bridge or an implant. The teeth start to drift into the open space. This can cause an unstable bite and orthodontic treatment is required to correct the bite. |
