Abstract
The present study will have as objective to evaluate the structural and mechanical characteristics of 03 resin-matrix ceramics for CAD/CAM, a resin nanoceramics (Cerasmart - GC), a glass ceramic in a resin interpenetrating matrix (VITA Enamic - VITA) and other zirconia-silica ceramic in a resin interpenetrating matrix (Shofu Block HC - SHOFU), after different polishing protocols (Ceramist…
