Perlèche is a skin condition characterized by painful sores at the labial commissures or corners of the mouth. It was first described in 1855 by the French physician Lemaistre, who named it after the ...
Drs. Parsaei, Uribe, and Steinbacher review the advantages and disadvantages of clear aligners in presurgical orthodontic treatment. Bone-anchor screws are used for intermaxillary fixation, and elastics are worn after surgery to maintain the bite. Three typical case examples are shown.
The Benefit Direct miniscrew attaches to a Hybrid Hyrax frame using a specially designed ring, as described by Dr. Wilmes and colleagues. This system enables an “appliance-first” approach while customizing the expander to situate the mini-implants in the best palatal bone.
The Ricketts Z sectional arch, extending between the upper canines and molars, can mitigate the usual side effects of intermaxillary elastics in Class treatment. A clinical study by Dr. Vasconcelos and colleagues measures the cephalometric and dimensional effects of the Ricketts arch.
A Forsus fixed functional appliance is used for anchorage during protraction of the lower molars in a young patient with missing lower second premolars. This approach corrects the Class II, division 1 malocclusion while avoiding overretraction of the lower incisors.
Dr. Gorczyca responds to a reader’s question about how to publicize a new job opening for an orthodontic assistant. Effective channels outlined here include Internet job sites, social media, dental networks, sales representatives, and local colleges and high schools.
Proper isolation is the most important concern in bonding a lower lingual retainer, but can sometimes be difficult to achieve with standard retractors. This simple Pearl uses cross-arch elastics to trap the tongue, thus ensuring an open field for the procedure.

This case illustrates the potential for unwanted tooth movement in a patient who presented with a 3-3 lingual flexible spiral-wire retainer in place. A retrospective 3D superimposition reveals a tendency for canine movement under a previous stiff-wire retainer that was not noted clinically.
