Abstract
Objective: To evaluate the surface roughness and biaxial flexural strength ceramics Vita Suprinity subjected to different forms of polishing. Methods: 80 will be made specimens with dimensions of 16 mm diameter and 1.5 mm thick flat faces which receive finish by sanding disc (400, 600, 800, 1000 and 1200 mesh). Next will be divided into eight groups (n = 10) by changing the surface treatm…
