Non-extraction Orthodontic Treatment of Class III SubdivisionMaloclussion: A Case Report

Abstract

Introduction: Correcting a Class III subdivision malocclusion is usually a challenge for
an orthodontist, especially if the patient’s profile does not allow for any extractions.
One treatment option is to use asymmetric intermaxillary elastics to correct the
unilateral anteroposterior discrepancy. However, the success of this method depends on
the individual response of each patient and his or her compliance in using the elastics. Case
Report: This case report presents a 23-year-old male who had Class III subdivision
malocclusion. He had straight profile. Intraoral examination showed mild crowding on
upper and lower anterior teeth. The treatment plan consisted of an extraction mandibular
third molars and MBT prescription bracket. Following the treatment, a satisfactory result
was achieved with an ideal facial profile. Conclusion: A good occlusion and Class I
molar relationship can be achieved with asymetric Class III elastics and third molar
extraction when patient compliance in using the elastics is satisfactory.
