Special notes on framework design
Framework design for fully contoured restorations:
Indicated especially where limited occlusal space is available, for frameworks that are not to be veneered
or for frameworks with body stains
The surface of fully contoured frameworks can carefully be optimized with rotary tools such as fine cutters
prior to sintering
Make sure that the occlusal surface is not changed by subsequent deepening of fissures, as notching
action may compromise the strength of the material Please note that flat occlusal reliefs can extend the
live expectancy of fully contoured restorations When making manual adjustments, make sure never to
separate the inter dental spaces of the frameworks with cutting discs or other rotary instruments, doing
so might damage the framework and compromise the strength of the material!
Important note:
Please ensure that the minimum wall thickness of the framework in the area of the occlusal surface is
respected even after occlusal adjustments
Framework design for veneered restorations:
Frameworks to be ceramically veneered are designed to reduced anatomical contour to provide maximum
support for the veneer
The frameworks can be veneered using the press-on technique
or the build-up technique.
Wall and border thickness:
Wall thickness, single crowns
Margin thickness, single crowns
Wall thickness, bridges
Margin thickness, bridges
