Casting and Finishing
After having cast the framework (e.g. with Academy Gold XH), carefully divest, sandblast / pickle and fit it on the model.
After separating, the metal framework is finished using tungsten carbide burs. If softer alloys are used, it is recommended
to work with limited pressure. A correct marginal design is paramount to attaining a reliable composite-metal bond. If
possible, create a tapered chamfer or wraparound design in the cervical area.
Carefully divest, sandblast or pickle ...
Version A:
Full-coverage veneer (ideal space)
Version B:
Partial veneer (limited space)
... and fit to the model.
Using a tungsten carbide bur, create a tapered cervical margin,
preferably by using a wraparound technique or a chamfer preparation.
Polish metal portions not to be veneered to a high gloss.
