Invisalign Treatment Accelerated by Photobiomodulation.

S methods have been proposed to accelerate orthodontic treatment and thus reduce treatment time. Surgical injury of the cortical bone through selective alveolar decortication, piezociThis 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 connectivetissue 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. In the case presented here, OrthoPulse was used in combination with Invisalign** to treat a difficult malocclusion. Although the ClinCheck** was designed for the usual two-week aligner wear period, PBM allowed the aligners to be changed every three days. The patient was instructed to use the appliance for five minutes per arch each day; cooperation was monitored remotely using a unique app in the OrthoPulse charging base that communicates through the Internet with the doctor’s office. The authors believe the patient’s ability to change aligners every three days improved her compliance. Aligner fit was checked at each appointment to ensure the teeth were tracking properly. In this way, an Invisalign treatment THE CUTTING EDGE
