CASE REPORT
Volume 51 : Number 7 : Page 419 : Jul 2017
A nonextraction approach is demonstrated in an adult high-angle patient with a skeletal Class malocclusion and severe crowding. By using low-friction, passive self-ligating brackets and bilateral temporary anchorage devices over 18 months of treatment, the authors are able to avoid any surgical intervention other than an advancement genioplasty.

Physiological Drifting of Ectopic Canines
Volume 51 : Number 8 : Page 481 : Aug 2017
If first premolars are extracted to make space for ectopic canines, rather than using loop or continuous-arch mechanics, the canines can be allowed to migrate naturally into the extraction sites. Two cases demonstrating this physiological drift are shown, and benefits of the approach are described.

A New Appliance for Efficient Molar Distalization
Volume 51 : Number 11 : Page 738 : Nov 2017
The Molar Thruster consists of a palatal acrylic covering with embedded Begg tubes, which are connected by bayonet wires to the palatal first-molar sheaths. Nickel titanium open-coil springs are compressed over the bayonet wires to deliver the distalizing force during the first phase of treatment.

Miniscrew Anchorage for Posterior Crossbite Correction in an Adult Patient
Volume 52 : Number 3 : Page 165 : Mar 2018
Drs. de Brito, Simões, and Machado resolve a unilateral posterior crossbite and lower anterior crowding in only 15 months. Buccal and palatal miniscrews are used initially to anchor elastic chain for molar intrusion. After leveling with fixed appliances, intermaxillary elastics are added to extrude the molars into occlusion.

A Zygomatic Miniplate as Skeletal Anchorage for Correction of Severe Skeletal Anterior Open Bite
Volume 54 : Number 4 : Page 221 : Apr 2020
An adult patient presents with a severe anterior open bite of skeletal origin. Avoiding orthognathic surgery, the treatment plan involves upper posterior intrusion and upper anterior retraction, with zygomatic miniplates inserted in the upper quadrants for skeletal anchorage.
