Blood flow velocity changes during orthodontic treatment
The research of blood flow velocity in the vessels of mucogingival junction and gingival interdental papilla in 47 patients was carried out with Minimax-Doppler device. 30-45% decrease of blood velocity during active orthodontic movements was shown. The perfusion normalizes in 2-3 weeks after the end of treatment. 60-75% decrease of blood velocity in first 3 days after surgical correction was shown. The perfusion normalizes after 14-21 days after surgery.
