Abstract
To develop a novel methodology to generate specimens for bi-axial flexure strength (BFS) determination from a 'chair-side' CAD-CAM feldspathic ceramic with surface defect integrals analogous to the clinical state. The hypotheses tested were: BFS and surface roughness (R(a)) are independent of machining variability introduced by the renewal or deterioration of form-grinding tools and that a post-machining annealing cycle would significantly modify BFS.
