Delayed Extraction of the Mesial First-Molar Root as a Means of Accelerating Space Closure
Volume 53 : Number 8 : Page 470 : Aug 2019
When a lower first permanent molar needs to be extracted, the adjacent second and third molars are often protracted to close the space. Drs. Lee and Park compare two patients to demonstrate how hemisection of the first-molar root can speed up protraction and reduce the risk of alveolar bone atrophy.

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.
