A Measurement Protocol for the Marginal and Internal Fit of All-Ceramic Crowns.

AIMS To evaluate in vitro the influence of firing on marginal and internal fit of all-ceramic milled and pressed lithium-disilicate crowns. MATERIALS AND METHODS One Standardized model with 1.6mm occlusal and 1.4mm axial reduction was used to fabricate 64 crowns. Using a factorial design, eight groups of lithium disilicate ceramics (n=8) using P=press, C… CONTINUE READING
