CONCLUSIONS
calculus, mandibular anterior teeth
PLAQUE

» No significant differences in the gingival health, plaque accumulation and calculus index were found between Ortho-Flex-tech™ wire and multi-strand wire groups.» Ortho-Flex-tech™ wire retainer was significantly more efficient to maintain the alignment of mandibular anterior teeth than multi-strand wire retainer, although both retainers clinically showed satisfactory alignment maintenance. » Although multi-strand wire retainers presented higher failure rate than Ortho-Flex-tech™ wire, this difference was not significant.
