Polymerization Efficiency of a Dual-Cured Resin Cement through Zirconia with Three Different Cusp Inclinations

Figure 1

Schematic diagram of the monolithic zirconia specimen design. The length and width of monolithic zirconia were 10.0 mm, and the thickness was 1.0 mm. The monolithic zirconia specimen consisted of two planes: the angles between the plane and horizontal were (a) 30°, simulating 30° cusp inclination and (b) 20°, simulating 20° cusp inclination. (c) The monolithic zirconia specimen was a flat plane, simulating 0° cusp inclination.
