Unilaterally Reinforced Facebow for Asymmetrical Correction
Volume 35 : Number 5 : Page 300 : May 2001
Certain Class II malocclusions are clearly asymmetrical, so that the maxillary molars need to be distalized more on one side than on the other. In this type of case, if I use a low-pull headgear, I in...

Clear-Aligner Treatment of Overerupted Upper Molars
Volume 50 : Number 1 : Page 48 : Jan 2016
Loss of teeth is often followed by overeruption of the opposing teeth and consequent esthetic, functional, and occlusal issues. Such overerupted teeth must be corrected prior to any prosthetic rehabilitation. Since coronal-reduction techniques may require additional endodontic and periodontal treatment before final crown restorations, overerupted teeth are typically treated with orthodontic intrusion. Surgically assisted methods such as corticotomy or surgical impaction increase the risks and cost of treatment. Extraoral devices require patient cooperation. Orthodontic correction using fixed appliances and bite planes may cause extrusion of the anchorage unit. Miniscrews can provide absolute skeletal anchorage without the need for patient cooperation, but are more invasive. This article suggests a way to intrude overerupted upper molars using anchorage from clear aligners.

A New Approach to the Diagnosis and Treatment of TMD in Growing Patients
Volume 55 : Number 9 : Page 536 : Sep 2021
The effects of TMD are generally interrelated with those of a developing skeletal malocclusion. Dr. Verulkar and colleagues show how to use AutoCAD software to evaluate condylar position before, during, and after treatment by means of a Gelb 4/7 grid superimposed on sectional TMJ views.

Tooth Extrusion with a Removable Appliance
Volume 27 : Number 5 : Page 0 : May 1993
Attempting to extrude ankylosed tooth with a fixed appliance can result in a disastrous tipping of the occlusal plane.1 A more conservative approach is advisable when ankylosis is suspected. A simple ...

THE CUTTING EDGE
Invisalign Treatment Accelerated by Photobiomodulation
Volume 50 : Number 5 : Page 0 : May 2016
This month's Cutting Edge article describes accelerated orthodontic treatment using photobiomodulation (PBM), a low-level light therapy that has been shown to accelerate bone and connective-tissue metabolism for wound healing in medicine. One commercially available PBM device, OrthoPulse, uses light-emitting diodes (LEDs) that produce 850 nanometers of light (very near the infrared spectrum), offering a safer mode of treatment than with laser light.
