[Physical principles of choosing orthodontic arches].
Physical principles underlying the choice of elastic arches for first stages of orthodontic treatment by means of edgewise technique are presented and clinical potentialities of superelastic nickel-titanium arches are discussed. Elastic properties of nickel-titanium arches available in Russia are reviewed. Using a previously proposed method, forces developed by strongly bent nickel-titanium arches in the oral cavity are estimated. The results are summed up in tables convenient for practical orthodontists. Based on estimations, a strategy of choice of orthodontic arches for first stages of treatment is proposed.
