Effect of repeated firings on flexural strength of
Forty-five zirconia specimens in shape of bars were cut sintered and divided in 3 groups (n = 15). Group 1 veneering ceramic was layered "in bulk" and fired. Group 2 veneering ceramic was layered in three layers individually fired. Group 3 veneering ceramic was layered in five layers individually fired.
