Evaluation of remodelling of jaw bone tissue in the dynamics of orthodontic treatment of tooth crowding O. V. Suslova, S. V. Shpak, V .G. Plotnikova, D. V. Stecenko Odessa National Medical University, Odessa, Ukraine Rearrangement of bone tissue occurs during the orthodontic treatment of tooth crowding due to the processes of resorption and apposition, the ability to influence these processes will allow to reduce the complications of orthodontic treatment purposefully. The aim: to investigate the processes of resorption and osteogenesis of jaw bone tissue during the orthodontic treatment of children with nonremovable devices. Materials and methods of the study. The research of mineral density of jaws has been held among 19 orthodontic patients between the ages of 12-14 with a tooth crowding. Dental sanation and professional oral hygiene have been made in children before the orthodontic treatment. Mineral density of bone tissue, volumetric part of bone trabecules, has been determined by estimation of spread rate of ultrasound waves of upper and lower jaws. Results. Conclusions. The received results confirm the data, in the dynamics of active orthodontic treatment, especially in the beginning, the processes of bone resorption dominates, while in a period of stabilization the synthesis of bone tissue is more active. Keywords: jaw bone tissue, crowding of teeth, ultrasound wave, echo osteometry.
