Objective: To evaluate the influence of the type of shoulder margins; Knife edge (F) and Chamfer (C) on the flexural strength of CAD / CAM lithium disilicate crowns in thicknesses of 0.8 mm and 0.5 mm.
Materials and Methods: 40 healthy upper premolars, in 2 groups according to the type of termination G1 = F and G2 = C; 2 subgroups referring to the material thickness Sg1 = 0.8mm and Sg2 0.5mm (5 crowns for each subgroup), were subjected to vertical (v) and horizontal (h) compression forces. The most frequent type of fracture was observed; cohesive in porcelain (cp), adhesive in porcelain (ap), mixed small (mp) and mixed long (ml).
Results: in preparations with 0.8 mm and 0.5 mm thicknesses, there was a significant difference in relation to the best termination, this was C; their values were Sg1 (h = 1347.2 N / v = 1402.0.F; Sg1 (h = 965.6 N / v = 794.8 N) .F at 0.5 mm showed better performance against horizontal forces C; Sg2 (h = 924.8 N / v = 813.4 N) and for F; Sg2 (h = 1217.0 N / v = 576.0 N)
Conclusions: the most frequent type of fracture is cp and ap finishing chamfer and knife edge can be used safely show acceptable values of flexural strength, by reducing the thickness of the chamfer restoration reduces its strength, the knife edge increases it.
