Impact of Orientation on Dimensional Accuracy of 3D-Printed Orthodontic Models
Volume 52 : Number 1 : Page 13 : Jan 2018
This study from Short, Drs. Favero, English and Kasper, was designed to evaluate the effect of model orientation in a stereolithographic 3D printer on the dimensional accuracy of the printed models in specific areas. Flat, perpendicular, and angulated orientations are compared in terms of accuracy and cost.

Inexpensive Orthodontic Treatment with a Prescription Custom-Base System
Volume 50 : Number 3 : Page 0 : Mar 2016
This month's article describes an innovative combination of three-dimensional imaging software, cone-beam computed tomography (CBCT), and intraoral scanning that facilitates the placement of low-cost, generic brackets with prescription custom bases. Unlike customized systems that consider only crown morphology, the authors' process combines the crowns and roots to allow proper root positioning during alignment of the crowns. A true "straight-wire" system, it can be applied to any bracket type, slot, or prescription.

Accuracy of 3D Facial Models Obtained from CBCT Volume Wrapping
Volume 49 : Number 10 : Page 641 : Oct 2015
The authors of this month's Cutting Edge column have taken on a question that I pondered several years ago: How accurate is a two-dimensional facial photograph that has been stretched" over a three-dimensional cone-beam computed tomography (CBCT) volume using Anatomage software? Although my query was born of simple academic curiosity, it is now a practical matter, as more orthodontists and orthognathic surgeons are becoming reliant on 3D analysis to diagnose and treat complex facial asymmetries.
