During orthodontic treatment, we can achieve differential movements by using photobiomodulation (PBM) as an adjuvant before applying force. We can expect a greater bone density that initially resists movement while applying PBM to the other teeth to achieve an accelerating effect. The proposed protocol is to use an 810 nm laser at 0.1W power, applying between 4 and 6J per tooth for 22 s on the vestibular and lingual root surfaces, following the axial axis of the tooth. The energy density depends on the tip selected in the instrument. Normal bone remodeling cannot be avoided by applying high doses of PBM. PBM should be applied before orthodontic force to reduce tooth movement. In addition, PBM can be used during force application to teeth that require acceleration to achieve differential movement in orthodontic treatments. The protocol is the same in both scenarios.
Core Tip: During orthodontic treatment, we can obtain differential movements by using photobiomodulation as an adjuvant before applying force to the teeth we want to use for anchoring, and photobiomodulation-assisted orthodontics to accelerate the movements when force is applied.
