The Straight-Wire technique involves the use of brackets that are programmed or individuallydesigned for each tooth, aiming at ideal positioning at treatment completion. This applies for bothconventional and self-ligated brackets. Since its introduction, the original proposal of ANDREWS included, in addition to standard brackets that were suitable for some individuals, the need to usedifferent prescriptions taking into account the type of malocclusion, treatment to be adopted andthe desired or possible tooth positioning at treatment completion –that is to say, the individualizationof appliances.

This premise has been ignored or simplified over time, relatively disagreeing withthe concepts of normality considered during the 1970s. Since then, the new diagnostic methodsstrongly based on facial analysis, as well as the knowledge achieved on the limitation of Orthodonticsin individuals with unfavorable growth, reinforced the concept that there is not only one normalocclusion, but many.

Therefore, the utilization of a single set of brackets for generalized treatmentof individuals with different malocclusions and therapeutic goals seems absolutely wrong. Thus,if treatment by the straight-wire technique is intended, with either conventional or self-ligatedbrackets, the individualization of prescriptions seems fundamental.
