Resum
A new strategy to obtain NiTi orthodontic archwires with variable correcting stresses in different segments is presented. Different heat treatments are applied in selected segments, which produce variations in the superelastic properties. These allow to modulate the correcting stresses to the requirements of the specific teeth. This method avoids laser welding, which is associated with corrosion and brittleness problems. The aim of this study is to analyze the effect of the heat treatment by zon...
