Fracture failure of the laminate veneers. The fracture may start as a crack from the margin and move toward the incisal edge as a result of improper finishing and polishing procedures (A,B), sudden chipping of the incisal edge as an effect of improper adjustments of the occlusion during centric relation or protrusive movements (C), or involvement of the incisal edge with the labial surface (D). The photos were sourced from the School of Dentistry, University of Alabama, Birmingham, USA.
