MATERIALS and TECHNIQUES: AN OVERVIEW
Crosstown offers both types of all ceramic restorative materials, zirconia and lithium disilicate. Zirconia has become the material of choice because of its strength, with tooth preparation parameters closer to that of full gold crowns; plus the fact that restorations can be conventionally cemented; and with the newest developments of more translucent zirconia materials, it can be used anywhere in the mouth. Lithium disilicate, emax , manufactured by Ivoclar Vivadent, has been the anterior restorative standard for more than a decade. It has been the clinician’s choice in the esthetic zone because of its natural translucency, both for veneers and full coverage crowns, although it does require the additional bonding step.
Crosstown uses only high noble or noble alloys and has alloy certificates available for those who request them. High noble alloy contains at least 40% gold and 60% (total) gold, palladium and platinum, where as noble alloys contain at least 25$ (total gold palladium and platinum. The colour of the alloy depends upon the gold content. Our high gold has a rich gold colour where as our medium gold and high palladium is silver in colour. We also have gold coloured alloy (low Au) available for full metal crowns or metal bridges. The Higher gold alloys can only be used for single units or to a maximum of three units for a bridge. Four or more units will require the strength of the medium gold and paladium alloys.
Fees are based on alloy weight and subject to change without notice.
