Morphological and structural analysis of a new bracket

Technical progress in bracket manufacturing MIM (Metal Injection Moulding) technology produced a new bracket characterised by a novel base: the R-system. The aim of this investigation was to make a morphological and structural SEM-EDS analysis of this bracket prototype. Its properties were compared to those of traditional metal brackets with meshed base produced by the same manufacturer. Although the SEM analysis showed localised defects, the EDS investigation showed that the materials composing the bracket base are homogenoeous.
