Effect of the Crystallization Process on the Marginal and Internal Gaps of Lithium Disilicate CAD/CAM Crowns

Table 1

Mean and standard deviation values of marginal and internal gaps in computer-aided design/computer-aided manufacturing (CAD/CAM) lithium disilicate crowns () before and after the crystallization process at each of the 5 points investigated (measured in micrometers [µm]).
