The mechanisms of teeth movement in orthodontic treatment and pharmacotherapy of preparations influencing bone resorption are viewed in the article. Mechanical forces used for orthodontic teeth movement cause structural changes in the bone tissue, breaking sequence of physiological remodelling. The movement of tooth or a group of teeth demands the beginning of bone tissue resorption process. However, bone resorption in the region of support tooth prevents effective treatment. Processes of bones remodelling during orthodontic treatment require correction that depends on the period of treatment and application of forces. Bone tissue resorption during osteoporosis has probably the same course as at orthodontic teeth movement. Therefore it is expedient to analyze osteoporosis pharmacotherapy to adapt it to processes of remodelling during orthodontic treatment
