Extraction for orthodontic treatment is not a
new idea. John Hunter emphasized the use of extraction
in orthodontics in his 1771 book Natural History of the
Teeth. For many years, the extraction in orthodontics has
been a subject of conflict. A significant number of
extractions are done as part of a comprehensive
treatment plan that involves the use of an appliance. The
type of the malocclusion and the patient's age may be
important factors in evaluating if extraction is required.
To extract or not to extract has always been and will
continue to be a source of debate in orthodontics. Teeth
extraction as part of orthodontic therapy may be
required in any of the following instances: Disparity in
arch length and tooth material, Sagittal inter-arch
relationship correction, Abnormal size and shape of
teeth, Skeletal-jaw malrelations. Extractions in
orthodontics include both interceptive extractions
carried out during the mixed dentition phase and
therapeutic extractions performed as a form of
orthodontic treatment to gain space. Therapeutic
extraction, Wilkinson extraction, balancing extraction,
compensating extraction, serial extraction, phased
extraction, enforced extraction, and atypical extraction
are some of the extraction treatments employed in
orthodontics.
