Marginal discrepancy of lithium disilicate crowns made with digital and conventional technologies.

Statement Of Problem: Digital technologies have brought different workflows to prosthetic rehabilitations, but analyses of the available processes and their influence on the marginal fit of complete crowns are lacking.

Purpose: The purpose of this in vitro study was to evaluate the marginal discrepancy of lithium disilicate complete crowns made with different workflows.

Material And Methods: Fifty lithium disilicate crowns were made with 5 different workflows (n=10): G1-Analog (control): conventional flow/pressed crown; G2-Hybrid: hybrid flow/milled crown; G3-Hybrid: hybrid flow/pressed crown; G4-Hybrid: hybrid flow/printed wax pattern/pressed crown; G5-Digital: digital flow/milled crown.
