 HISTORY OF ORTHODONTICS

4. Orthodontics is that branch of dentistry
concerned with prevention, interception and correction
of malocclusion and other abnormalities of the
dentofacial region.
 The word orthodontics is derived from the greek words,
orthos- correct
odontos- teeth

5. Malocclusion
Normal occlusion

6. In 1922, the British Society for the study of
orthodontics has defined the speciality as,
“ Orthodontics includes the study of the growth and
development of the jaws and face particularly, and the
body generally as influencing the position of the teeth;
the study of action and reaction of internal and external
influences on the development and prevention and
correction of arrested and perverted development.”

7. The art and science of orthodontic can
be divided into three categories based on the
nature and time of intervention into:-
 Preventive orthodontics.
 Interceptive orthodontics.
 Corrective orthodontics.
 Surgical orthodontics.

8. It is the action taken to preserve the integrity of
what appears to be normal for that age.

9. It is that phase of the science and art of
orthodontics , employed to recognize and eliminate
potential irregularities and malpositions in the
developing dentofacial complex.

10. Corrective orthodontics
recognizes the existence
of malocclusion and
the need for employing
certain technical
procedures to reduce
or eliminate the problem.

11. They are the surgical procedures that are
undertaken in conjunction with or as an adjunct to
orthodontic treatment.
 The surgical orthodontic procedures are usually carried
out to remove an etiological factor or to treat very
severe dento- facial deformities that cannot be treated
by orthodontic therapy alone.

13. The aims and objectives of orthodontic therapy
have been summarised by Jackson as the Jackson's
triad.
The three main objectives of orthodontic treatment
are
1. Functional efficiency .
2. Structural balance .
3. Esthetic harmony .

14. Many malocclusions affect normal
functioning of the stomatognathic system. The
orthodontic treatment should thus aim at
improving the functioning of the oro-facial
apparatus.

15. Patients with anterior open bites and those with
markedly increased or reverse overjets often
complain of difficulty with eating , especially when
incising food.

16. The treatment should maintain a balance
between teeth, surrounding soft tissue envelop and the
associated skeletal structures.

17. Many malocclusions are associated with
unsightly appearance of teeth and can thus
affect the individual’s self image , well being
and success in society.
 Thus the orthodontic
treatment should aim
at improving the esthetics
of the individual.

18.  Alteration in tooth position.
 Alteration in skeletal pattern.
 Alteration in soft tissue pattern.

19. Orthodontic treatment is made possible by the
fact that teeth can be moved through the bone to ideal
location by applying appropriate force on them.

20. Malocclusion may be associated with skeletal
disharmony involving the jaw bones. Deviations from
the normal can arise in size, positions and relationship
between these skeletal components.
Orthodontist can bring about the changes in all the
three planes of the space i.e
 Sagittal, transverse and vertical.

22. The soft tissues that envelop the dentition are
greatly influenced by the placement of dentition. It is
possible to bring about favourable changes in the soft
tissue pattern by orthodontic treatment.

23.  In 25 Bc, Aulius cornelius celsus advocated the use of
finger pressure to align irregular teeth.
 Pierre fauchard is considered as the father of modern
dentistry and in 1723 he gave probably the first
orthodontic appliance called a Bandelette.
 Emerson c Angeil (1823-1903) first advocated the
opening of the mid palatal suture.

24.  William E. Magill (1823-1896) was the first person to
band teeth for active tooth movement.
 Edward. H. Angel (1855-1930)is consider the father of
modern orthodontics.
His contributions are
- Classifications of malocclusion
- Pin tube
- Edgewise
- Ribbon arch
- E arch

25.  Calvin case(1847-1923) believed that extraction to
achieve stable orthodontic treatment and to improve
facial esthetics.
 Martin Dewey(1881-1933) has given modification for
Angles classification of malocclusion.
 In 1931 Holly Broadbent and Hofarath developed
Cephalometric radiographs.
 In 1955 Buonocore introduced acid etching technique.
 Raymond Begg gave light wire appliance.
 Viggo Anderson in 1910 developed activator.
