Extraction of lower incisors can be considered a treatment option in cases of Class I malocclusions with mandibular crowding, specially when a tooth-size discrepancy is observed between lower and upper arch; that can be demonstrated through Bolton analysis. This dental discrepancy is normally due to upper teeth's decrease in width and lower teeth's increase in width. In this clinical case, the treatment with lower incisor extraction, provided a quick therapy, with minimum undesirable effects.
