Evaluation of physical properties of esthetic brackets after clinical use: Study in situ

Conclusions Ceramic brackets with metal-inserted slots had significant changes in physical properties during clinical use. The dimensional changes encountered were small and appeared clinically nonsignificant. However, the progressive increase in the coefficient of friction must be taken into consideration because it may compromise the clinical performance of the appliance.
