Correction of Bilateral Class II Malocclusion Using Heat-Activated Nickel Titanium Wires
Volume 50 : Number 1 : Page 41 : Jan 2016
Various extraoral and intraoral fixed appliances have been used in Class II cases to distalize the upper molars without extractions. The main disadvantage of these appliances is anchorage loss, which may cause mesial tipping of the anterior teeth unless skeletal anchorage is added. There is also some controversy regarding the effectiveness of distalizing appliances once the second and third molars have erupted. This case report describes the use of heat-activated nickel titanium wires for molar distalization, referred to as the Loca-System, to correct a Class II malocclusion with skeletal asymmetry.

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.
