WHAT DOES ORTHODONTICS
MEAN?
Orthodontics is the term given to the
branch of dentistry concerned with
diagnosis prevention and treatment of
dental and facial irregularities. The aims of
orthodontic treatment are to provide an
attractive smile with healthy teeth and jaw
joints.

ORTHODONTICS ---- GREEK WORD (FIRST COINED BY FOULON)
ORTHOS ----- CORRECT
DONTOS ----- TEETH

BRITISH SOCIETY FOR THE STUDY OF
ORTHODONTICS
(BSSO, 1922)
“ORTHODONTICS: ORTHODONTICS INCLUDES THE STUDY OF THE
GROWTH AND DEVELOPMENT OF THE JAWS AND FACE PARTICULARLY,
AND THE BODY GENERALLY, AS INFLUENCING THE POSITION OF TEETH;
THE STUDY OF ACTION AND REACTION OF INTERNAL AND EXTERNAL
INFLUENCES ON THE DEVELOPMENT, AND THE PREVENTION AND
CORRECTION OF ARRESTED AND PERVERTED DEVELOPMENT.”

AMERICAN ASSOCIATION OF ORTHODONTISTS
(AAO, 1996)
ORTHODONTICS (DENTOFACIAL ORTHOPEDICS)
THE AREA OF DENTISTRY CONCERNED WITH THE SUPERVISION,GUIDANCE AND
CORRECTION OF THE GROWING AND MATURE DENTOFACIAL STRUCTURES,
IN CLUDING THOSE CONDITIONS THAT REQUIRE MOVEMENT OF THE TEETH OR
CORRECTIONOF MALRELATIONSHIPS BETWEEN AND AMONG TEETH AND FACIAL
BONES BY THE APPLICATIONS OF FORCES AND / OR THE STIMULATION AND
REDIRECTION OF THE FUNCTIONAL FORCES WITHIN THE CRANIOFACIAL
COMPLEX

WHAT ARE THE BENEFITS OF
ORTHODONTIC TREATMENT?
•Better appearance of
teeth, smile and face
•Improved self esteem and
self confidence
•Cleaner, healthier teeth
An even bite for improved
jaw alignment and function

AT WHAT AGE MAY I
START TREATMENT?
Ideally, children should be seen for their initial
assessment between the ages of 7 and 10 years.
This will allow the child’s growth and changing
dentition to be monitored until all baby teeth have
been lost and treatment can begin. Obviously all
cases are individual, and some children may start
treatment at a younger age. However, you are
never too old to start orthodontic treatment, and
people of all ages can reap the benefits. Treatment
may take a little while longer in adults, but the end
result is just as pleasing.

Where do we need space in Orthodontics ?
a. Crowding
b. Proclination
c. Deep bite
d. Rotated anteriors – Irregularly placed
anteriors
e. Constricted arches

METHODS TO GAIN SPACE
1.Proximal stripping / Slicing
2.Expansion of arches
3.Distalization
4. Protracting anteriors / flaring
5.De rotation of posteriors
6.Uprighting of molars
7.Extraction

What about extraction
space?
