This is my first VITA Enamic crown. It polishes more like a traditional ceramic. Mill and margin is excellent. No chipping even with a thin margin, so no need to bulk margin prior to mill. Post-mill finishing steps included occlusal refinement with 35 carbide inverter cone, Dimond Twist (Preimer) fibra wheel for pre-polish and then stiff polishing brush with F-Diashine. Using a stiff polishing brush with Diashine, slow rpm, and heavy pressure application will polish the grooves and pits zones.
