[Biomechanical justification of third order bends application by using edgewise technique].
Aim of this study is to give theoretical substantiation of magnitude of arch wire diameter decrease in area of adjacent teeth for reducing undesirable reciprocal deflections by redistribution of the force on more teeth during making torsion bends on rectangular orthodontic arch wires for correction of vestibulolingual position of individual teeth. By means of mathematical analysis, was determined relationship between the angle of tooth inclination and the radius of orthodontic arch wire overcast, which will allow managing moments that affect adjacent teeth.
