Mandibular molar protraction using round Australian wire and miniscrew anchorage with modified corticision in an adult with first molar loss: A case report

Abstract

A 27-year-old adult female presented with the chief complaint of bilateral mandibular first molar absence and strongly preferred to use wisdom teeth rather than prosthetic replacements. Treatment was carried out using a round Australian wire fixed orthodontic technique. The second and third molars were mesially moved with a bilateral terminal helical loop combined with curved tip-back bends in Australian wire. Miniscrew anchorage was placed in the mandibular premolar area to assist in the protraction of the second and third molars. Additionally, a modified cortical drilling technique was employed to accelerate tooth movement. A neutral molar relationship was established while maintaining the patient's facial profile.
