Fit of high translucent zirconia fixed dental prostheses using two different intraoral scanners

Purpose: To assess the marginal and internal fit of monolithic zirconia fixed dental prostheses (FDPs) comparing two different intraoral scanners and assessment methods. Materials and Methods: A maxillary typodont with three prepared teeth allowed the fabrication of five-unit, high-translucency monolithic zirconia FDPs. The typodont was scanned with intraoral scanners Cerec Omnicam and 3Shape Trios 3. A total of 30 FDPs were milled from presintered high-translucency zirconia blocks. Dual-scan and silicone replica assessments were used to determine marginal and internal gaps. Results: Statistical significance was observed for marginal gap (Trios:
