Comparison of deflection forces of esthetic archwires combined with ceramic brackets

J. appl. oral sci; 26 (), 2018
Abstract Coated archwires and ceramic brackets have been developed to improve facial esthetics during orthodontic treatment. However, their mechanical behavior has been shown to be different from metallic archwires and brackets. Therefore, the aim of this study was to compare the deflection forces in coa...
