INDICATIONS FOR EXTRACTION IN DENTISTRY Therapeutic extractions in orthodontics are primarily done for the following reasons: 1. Achieving arch space To correct negative osseodental discrepancy (DOD), which usually manifests as crowding. One of the most important and common indications for orthodontic extractions is the lack of space in the arch that usually manifests as more or less localised crowding. Achieving proper dental alignment in their bony bases requires consideration of the compromise between the size of the teeth themselves and the size and shape of their bases within the framework of the dentofacial skeletal relationship for each patient. The orthodontist can act on the maxillomandibular skeleton well using orthopaedic means in children, as well as in adolescents with residual growth or with surgical care where there is no such growth. In every case, the limits imposed by the individual maxillomandibular anatomy must always be assessed when deciding whether a malocclusion with negative DOD can be resolved conservatively or whether one must resort to extractions 2. Facial aesthetics To reduce dentoalveolar protrusion. One of the main indications for orthodontic extractions is to achieve a more harmonious profile in patients with excessive facial convexity secondary to dental biprotrusion. The positive effect on the profile of extracting the bicuspids in patients with a normal vertical dimension or a little short and
