Forced Eruption of Palatally Impacted Canines Using Bracket-Head Miniscrews
Volume 48 : Number 9 : Page 576 : Sep 2014

A Vestibular Rapid Palatal Expander
Volume 50 : Number 2 : Page 0 : Feb 2016
Various types of rapid maxillary expanders have been introduced; while they all have their advantages and disadvantages, each is built around an expansion screw in the palatal area. This article describes a different approach to the orthopedic treatment of a maxilla with transverse bone deficiency. A vestibular expander called the was developed to address some of the drawbacks of traditional expanders and to optimize the disjunctive action of the appliance during its entire period of use in the oral cavity.

A "Renewable" Archwire for Uprighting Impacted Lower Second Molars
Volume 50 : Number 4 : Page 0 : Apr 2016
An impacted lower second molar is relatively rare, with an incidence of .06-.3%, but when encountered can be the most challenging problem in an otherwise routine orthodontic treatment. Uprighting usually needs to be done as quickly as possible to restore chewing function, placing a premium on efficient mechanics. Unfortunately, since treatment commonly involves individual manipulation of bracket positions, frequent wire changes or bending, or placement of auxiliaries, an impacted lower second molar is difficult to correct with pre-programmed orthodontic appliances such as Invisalign, SureSmile, or Incognito.

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.
