M. Molin et S. Karlsson, THE FIT OF GOLD INLAYS AND 3 CERAMIC INLAY SYSTEMS - A CLINICAL AND IN-VITRO STUDY, Acta Odontologica Scandinavica, 51(4), 1993, pp. 201-206
Four inlay systems-gold, Cerec, Mirage, and Empress inlays-were evalua
ted for their adaptation to stone die and clinically to the tooth by m
eans of a replica technique. Twenty inlays of each system were placed
on premolars and molars in the lower jaw. A microscope was used to mea
sure the adaptation at the approximal margin, at the inner axial wall,
and at the occlusal cavosurface area. An overall better fit was obser
ved for the gold inlays than for the ceramic inlays. When the differen
t measuring locations were compared, a better fit was found for the oc
clusal area. The greatest discrepancies were recorded for the Cerec in
lays, whereas the Mirage and Empress inlays were comparable.
