Abstract:
On the base of experimental dilatometric investigations the thermal expansion behaviour of the Ni-Cri-based alloys Gisadent NCA, Gisadent NCS 1, Mikrostom-1, Wiron 77 and Wiron 88 was tested and the expansion coeffizient and the solid shrinkage determinated. The results are discussed referable to the compatibility metal/ceramic and in connection with the accuracy of fit of cast dental appliances.
