Drs. Albertini, Albertini, Lombardo, and Siciliani describe two multidisciplinary adult extraction cases (one presurgical) in which outstanding results were achieved with a preadjusted lingual system and simple sliding mechanics. Keys to anterior tip and torque control are highlighted.
A previous orthodontist had recommended premolar extractions to correct this mild skeletal Class III. Drs. Karpov and Kuncio instead use a miniscrew-anchored rapid palatal expander and a corticotomy, followed by custom archwires, to achieve the needed skeletal and dental changes.
Dr. Chen and colleagues measure the deviation of posterior attachments from ideal positions after indirect bonding to 3D-printed models. Template trays were sectioned in four different ways (whole, halves, thirds, and sixths) for testing of bonding accuracy.
Posterior resin turbos, as often used in deep-bite cases, can be applied to control the vertical dimension during presurgical or anterior open-bite treatment. A step-by-step technique is presented, along with a procedure for sequential additions to the build-ups.
