PBM healing. This device accelerates tooth movement during clear aligner orthodontic treatment, potentially doubling the speed and reducing the pain associated with the process. Purchased a year ago from a dental clinic for 184,000 yen. User is a woman in her 20s. Using the device for 4 minutes per side, for a total of 8 minutes a day, allows for aligner changes in as little as 3 days and can reduce pain. Please understand that this is a used item. The box and all accessories are included, and there are no defects. The device will be disinfected before shipping. #ClearAlignerOrthodontics #Invisalign #DentalOrthodontics #TeethAlignment #Orthopulse #Orthopulse #PBMHealing #PBMHealing #Orthodontics #PBM #LightAccelerationDevice #OrthodonticAccelerationDevice #PBMOrt #HealingLight
