Lower incisor extraction: Can it be justified? A report of two cases.

Extraction versus nonextraction debate is still continuing since 1900s. Some cases demand extraction of premolars, but the decision making is diffi cult in the border line cases with good facial esthetics. Lower incisor extraction becomes a therapeutic alternative to premolar extractions in lower anterior crowding cases with good facial esthetics and well occluded posterior teeth. Diagnostic setup reveals the posttreatment occlusal possibilities and hence the most important step in the diagnosis and treatment planning of these cases. Lower incisor extraction decision would be a better option in cases with anterior Bolton's discrepancy. Two cases treated with single lower incisor extraction, indications, contraindications and measures to attain posttreatment stability are discussed in this presentation. [ABSTRACT FROM AUTHOR]
