Volume 56 : Number 8 : Page 473 : Aug 2022
Dr. Boanger shows how maxillary incisors can be intruded as a block with progressive step-up bends in a sectional wire, using indirect anchorage from buccal mini-implants. The intrusive force produces incisor proclination for arch lengthening, and a buccal root-torquing bend then provides axial control.

Volume 56 : Number 9 : Page 508 : Sep 2022
Intrusion of overerupted molars is difficult to achieve in adult patients with conventional mechanics. Dr. Derton and colleagues use segmental posterior archwires to control torque with skeletal support from three miniscrews: two buccal interradicular and one palatal.
