Journal ArticleDOI
Marginal accuracy and geometry of cast titanium copings.
TL;DR: Casting shrinkage was characteristic, particularly along the horizontal axis in the plane of the shoulder, and horizontal linear shrinkage of 45-degree margins was greater than that for the 90-degree form.

Randomized controlled within-subject evaluation of digital and conventional workflows for the fabrication of lithium disilicate single crowns. Part III: marginal and internal fit
Marco Zeltner,Irena Sailer,Sven Mühlemann,Mutlu Özcan,Christoph H. F. Hämmerle,Goran I. Benic +5 more
TL;DR: No significant differences were found between the conventional and digital workflows for the fabrication of monolithic lithium disilicate crowns and in the occlusal regions, the conventionally manufactured crowns revealed better fit than the digitally fabricated crowns.
Journal ArticleDOI
Evaluating the marginal fit of zirconia copings with digital impressions with an intraoral digital scanner
TL;DR: The marginal gap between the restoration and definitive cast base metal die was greater in the groups that use the digital impression method than in the group that used the conventional impression method, but the marginal discrepancies of all of the groups were clinically acceptable.

The marginal fit of selective laser melting-fabricated metal crowns: an in vitro study.
Dan Xu,Nan Xiang,Bin Wei +2 more
TL;DR: Selective laser melting-fabricate cobalt-chromium dental crowns found improved marginal gap widths compared with traditional cast crowns, and this technique is attracting interest in prosthetic dentistry.

Comparison the Marginal and Internal Fit of Metal Copings Cast from Wax Patterns Fabricated by CAD/CAM and Conventional Wax up Techniques
TL;DR: Within limitations of this study, conventional method of wax-pattern fabrication produced copings with significantly better marginal and internal fit than CAD/CAM (machine-milled) technique.
