Although fracture of the tooth during surgical removal is common, mandibular fracture during lower third molar removal is an unusual and major complication. Possible aetiologies are age, gender, the position of the tooth, uncontrolled excessive force applied, insufficient surgical experience and improper instrumentation. Symptoms can vary widely and treatment options range from prescription of a soft diet to surgical treatment by open reduction and internal fixation. We present two cases of the treatment and follow-up of fracture of the angle region of the mandible during removal. © 2012 Australian Dental Association.
