The first clinics dedicated to sleep medicine appeared in the 1970s, primarily for the treatment of obstructive sleep apnea (OSA). Caused by complete or partial obstruction of the upper airway, OSA is...
Drs. Oliverio, Cremonini, Lombardo, and Siciliani designed this clinical study of 38 orthodontic patients to evaluate the efficacy of various at-home whitening protocols when the bleaching agents were sprayed directly onto the interior surfaces of clear aligner trays.
Flipping a bracket 180° or switching it between the right and left sides of the arch can be useful in altering the prescription for biomechanical purposes. Drs. Kravitz and Miller outline the effects of bracket flipping and switching on torque and tip.
The combination of maxillomandibular advancement surgery with orthodontic treatment can be effective in patients with obstructive sleep apnea. Dr. Uesugi and colleagues follow changes in a skeletal Class II patient’s upper airway configuration and respiratory function for three years after surgery.
Orthodontic brackets and archwires tend to tear alginate material and distort impressions. This simple method employs elastomeric modules to block out the bracket edges and undercuts when taking alginate impressions, thus producing better working casts.
Smartphones now have built-in features for calculating angles and tilt. The author shows how to attach a ribbon arch plier to a spare phone case to measure the exact amount of torque being added to an archwire, using a free smartphone app.
A Class II, division 1 patient’s severely impacted mandibular second molars are uprighted using conventional biomechanics, without temporary anchorage devices, and the maxillary second molars are then extracted to create space for distalization of the upper arch.
