A Three-Dimensional Digital Insertion Guide for Palatal Miniscrew Placement
Volume 50 : Number 1 : Page 12 : Jan 2016
Miniscrew anchorage has significantly reduced the need for patient compliance and allowed orthodontic treatment of more types of cases without surgery. Despite its increasing popularity, however, miniscrew placement may be dangerous if the clinician lacks adequate information on the anatomy of the insertion area. Various surgical guides based on digital volumetric imaging, such as cone-beam computed tomography (CBCT), have been proposed as aids to allow precise insertion of miniscrews into the interradicular spaces.

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.
