Adaptación de cofias metálicas de Co-Cr realizadas sobre dos líneas de terminación y fabricadas con dos técnicas

The new digitized technologies have allowed to migrate from the technique of lost cast wax by centrifugation (CPC) to the subtractive manufacturing by CAD / CAM as the technique of soft-block milling (SMB).Objective:The purpose of this study was to compare the marginal and internal adaptations in metal Co-Cr copes on two termination lines: chamfer and bevel made by two techniques: CPC and SMB.Material and Methods:Two Co-Cr master models with chamfer and bevel termination were made, 4 study groups were formed and 13 copings were made per group. For the evaluation of the marginal and internal adaptations the replication method was used in silicone, then with a stereomicroscope the marginal and internal discrepancies were evaluated.Results:For the marginal discrepancy between the two techniques, only statistically significant differences were observed for the bevel termination (p
