Marginal accuracy of complete crowns made from alternative casting alloys

Influence of margin design on the fit of high-precious alloy restorations in patients

“…17,[28][29][30] Nevertheless the good results are not reflected in patients, especially with subgingival preparations. 22,31,32 In these situations, the reduced accessibility of the finish line and the inevitable moisture in the sulcus can be supposed to be the factors limiting the exact reproduction of the finish line in the impression.…”

Fabrication of crown restoration retrofitting to existing clasps using CAD/CAM: Fitness accuracy and retentive force

“…In one technique, a lost wax procedure is carried out for metal restorations, but there are still many problems. Since all laboratory processes are manually completed, the quality of the prosthesis is affected by the skill of the dental technicians [9][10][11]. It is difficult to give appropriate ideal contours, undercuts, rest seats, and guiding planes to the new retrofitted crowns using the conventional lost wax technique.…”

An audit of the quality of base metal cast restorations provided within the restorative department of a UK dental institute

“…Older studies 21,22 have found that gold alloys (particularly high-gold) exhibit better marginal fit than base metal alloys including NiCr.…”
