Morphometric evaluation of the slot of aesthetic orthodontic brackets.

Introduction: : Dental malocclusion is a public health problem and orthodontics the specialty in charge of diagnosing treating it, aesthetic brackets are an alternative, costs varied, which makes its precision doubtful. Objective: Evaluate measurement geometry slot three brands verify their precision. Material Methods: Twenty-four Roth prescription 0.022” polycrystalline ceramic were evaluated brands: American Orthodontics (United States), Morelli (Brazil) Class One (China). Eight samples measured per group specialized laboratory certified calibration, measurements internal external height verified, mesial distal; parallelism each bracket. The results processed with SPSS 22 tests variance (ANOVA), Tukey Student's t used. Results: brackets' grooves do not correspond to announced by manufacturers, these greater, however, within tolerance range (p<0.01); slots mesio-distal direction lingual vestibule parallel One. Conclusion: this study indicate that supports oversized, precise varies greatly between prices. three-dimensional control tooth could be compromised.
