Effect of Maxillary Third Molar Extraction vs. Non-extraction on Distalization of First Molars in a Group of Adolescent Patients

After surgical extraction of unerupted upper third molars, the maxillary first molars were distalized using a labial bow with two soldered crimpable hooks distal to the upper lateral incisors. The labial bow fitted in the flying tube of the upper first molar bands. It was anchored bilaterally to the infra-zygomatic mini-implant by closed coil spring that applied a force of 300gm on each side
