My March 2020 Editor’s Corner, entitled “The 3D Printing Revolution,” was written just after the first time I witnessed a 3D printer being used routinely in a private orthodontic practice. My initial ...
The horseshoe palatal anchorage plate relies on precise microscrew positioning to facilitate three-dimensional control of tooth movement, while simplifying the insertion procedure and reducing patient discomfort. Dr. De Gabriele and colleagues present two typical skeletal Class II cases.
Excessive incisor retraction in a bimaxillary protrusive case can lead to adverse iatrogenic sequelae. Dr. Singh uses cone-beam computed tomography to document alveolar bone remodeling after treatment of a patient whose upper incisors were retracted bodily past the palatal cortical plate.
Drs. Poulos, Barrons Olsen, and Park designed this study to investigate the use of in-house 3D printers by private practices and academic residency programs. Preferred printers and software programs are surveyed, along with common applications, barriers to purchase, and predictions for the future.
Dr. Valarelli and colleagues review effective methods for compensatory fixed-appliance treatment of hyperdivergent adult patients with severe skeletal anterior open bites, including first-molar extractions and the use of lingual spurs and intermaxillary elastics. Their protocol is illustrated in a sample case.
Several authors have contended that clear aligners can provide enough vertical control for maxillary molar intrusion without miniscrew anchorage. In this case, an upper first molar is intruded using only aligners and bonded attachments, while bleaching and prosthetic restoration are performed during the final stage.
This Pearl describes the application of functional resin turbos on the upper and lower premolars to help correct a Class II malocclusion. When used in conjunction with fixed appliances and elastics, their effect is similar to that of a Twin Block.

The authors demonstrate how accurate evaluation of an asymmetrical skeletal Class III can enable comprehensive surgical-orthodontic treatment to correct the skeletal discrepancies in all three planes of space, producing optimal occlusal function, facial esthetics, and long-term stability.
