RESUMO
UNLABELLED: Lower incisor extraction in orthodontic treatment was very rare modality of orthodontic treatment because there are few patients who meet the standards for such treatment. Proper diagnosis and treatment planning should be done to achieve good occlusion and facial esthetics. Criteria for lower incisor extraction included degree of crowding, tooth size discrepancy, pathologic condition, vertical overbite, sagittal incisal relationship, skeletal growth pattern and age of the patient. This article comprises of a case of class I malocclusion treated with lower incisor extraction, with comprehensive analysis, diagnosis and treatment planning, treatment results were satisfactory. CLINICAL SIGNIFICANCE: Mandibular incisor extraction can be an effective treatment option in borderline cases with mild crowding in lower arch. Minimal alteration of mandibular arch form is key factor for success and stable results.
