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.
