Crowding correction through extraction of a lower incisor

Tooth-bone discrepancy, or crowding in the lower arch, istraditionally corrected by removing fi rst or second premolars; theextraction of a lower incisor is an uncommon approach but presents another treatment alternative. Treatment goal: to present the case report of a patient who was given this alternative treatment. The patient had 15 years 4 months of age. The intraoral analysis revealed a normodivergent skeletal class I with bilateral molar class I, bilateral canine class I, decreased overbite, and increased overjet. She had lower moderate and mild upper crowding as well as a habit of digital suction. Treatment time was one year and four months.
