Minimally invasive orthodontic-assisted extraction of mesioangular impacted lower third molar:a case report

Extraction of impacted lower third molar is a common procedure.Damage to the inferior alveolar nerve(IAN) is one of the severe complications,in that the roots of the tooth are often close to the nerve canal when it is impacted at a low position.For mesioangular impacted lower third molar,the adjacent second molar is likely to be injured accidentally during extraction.A case of mesioangular impacted lower third molar with its roots close to the inferior alveolar nerve canal treated with minimally invasive orthodontic assisted extraction was reported in this paper.The purpose of the orthodontic treatment was to upright the third molar to simplify the procedure of extraction,and to reduce postoperative complications.
