OBJECTIVE To determine the location and size of enamel fracture (EF) when debonding a bracket. MATERIALS AND METHODS Tests on actual EF situations were conducted in different debonding load modes (tension, shear, and torsion) via mechanical testing, finite element model (FEM) analysis, and scanning electronic microscopy (SEM). Through these simultaneous analyses of the relationships among debonding load modes, value/distribution of stress, and actual enamel fracture location/size, an… CONTINUE READING
