In this paper the nylon-resin technique is proposed as the idoneous fixing technique of dentary displacement treatment and/or radicle fracture due to dentoalveolar traumatisms, of high incidence in children. In order to probe the effectiveness and advantages of this technique a comparative study against the wire-resin technique was done. The fixing time proposed for both procedures was 14 days. The techniques were applied in the same number of patients indistinctly in age, sex, affected teeth, and type of lesion. After evaluation we observed that the proposed technique is superior in several aspects: fulfils with the requirements of an ideal ferule, is aesthetic, easier to elaborate, more resistant, more compatible with tissues, and because of their semirigidity, more functional.
