THE CUTTING EDGE
Long-Distance Orthodontic Treatment with Adjunctive Light Therapy
Volume 49 : Number 12 : Page 757 : Dec 2015
Orthodontists are constantly looking for ways to improve the ease of treatment, patient comfort, and "throughput". Prescription bonded brackets and nickel titanium wires are just two examples of these efforts. In our Cutting Edge column this month, Dr. Timothy Shaughnessy explores another trend in orthodontic treatment: accelerated orthodontics. During my five decades in the profession, various methods for speeding up treatment, including electrical stimulation and hormonal and chemical applications, have occasionally surfaced. None of these has gained widespread acceptance. Now gaining some traction, however, are both invasive procedures that stimulate the body's reparative process and noninvasive vibratory stimulation of the periodontal membrane.

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.
