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.
