A Biomechanical Approach to Second-Molar Intrusion
Volume 47 : Number 10 : Page 608 : Oct 2013
Adult patients with missing mandibular molars may present with altered occlusal planes due to extrusion of the unopposed antagonists and migration of teeth into adjacent spaces.1 In such cases, the ma...

Digital Technology for the Management of Impacted Canines in Lingual Orthodontics
Volume 50 : Number 11 : Page 663 : Nov 2016
Upper canines are the most commonly impacted teeth, second only to third molars.1 Impacted upper canines occur in about 2% of the population and are twice as common in females as in males. About one-t...

Volume 49 : Number 12 : Page 770 : Dec 2015
The advantages of a rapid maxillary expander (RME) anchored to the deciduous teeth in the mixed dentition have been described in the literature, as has the use of a cast-metal Haas-type RME bonded to six deciduous teeth.[ref]1-4[/ref] If the upper first permanent molar remains impacted against the second deciduous molar, however, the distal root of the deciduous molar may experience early resorption, leaving the permanent molar unable to erupt spontaneously. It then becomes impossible to band the deciduous second molar, especially considering the poorly retentive coronal anatomy of the deciduous teeth. The use of bands could not only increase the risk of appliance failure, but create another obstacle to first-molar eruption. An alternative approach would be to extract the deciduous second molars and expand the permanent teeth, but this could lead to early loss of the leeway space, with the consequent need to regain space by distalizing the upper molars or by using extraoral traction in a second treatment phase, or to wait for full eruption of the first molars. It might also require a transpalatal bar to be used before expansion to correct a buccal molar inclination or molar rotation.

Use of Osseointegrated Implants for Orthodontic Anchorage
Volume 51 : Number 7 : Page 406 : Jul 2017
This biomechanical setup, called the handlebar-style technique, uses an osseointegrated implant-supported device as anchorage to accommodate vectors for correction of a single misaligned tooth while preventing undesirable movement of adjacent teeth. An existing implant can be used or one can be strategically placed, as illustrated in two cases.

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.

Interdisciplinary Aligner Treatment of Short-Face Patients
Volume 51 : Number 7 : Page 382 : Jul 2017
The authors introduce a comprehensive esthetic interdisciplinary treatment approach, including clear aligners, for short-face patients with complex facial, smile, and esthetic problems. As demonstrated in four cases, the orthodontist may be required to coordinate treatment with prosthodontics, periodontics, restorative dentistry, and orthognathic surgery to achieve optimal results.

The Biocreative Strategy Part 5: Labial and Lingual Space Closure in Extraction Treatment
Volume 52 : Number 10 : Page 528 : Oct 2018
Space closure in Biocreative extraction therapy is simple to manage, as Dr. Kim and colleagues demonstrate in Part 5 of their six-part series. A bonded mesh tube appliance is shown for labial retraction using Class I and Class III elastics; an anteroposterior lingual retractor is anchored by a palatal miniplate for lingual mechanics.
