Sinter pearls for dental CAD/CAM technology

Sinterization of Zr-oxide substructures. Full ceramics are the answer to patients demands for highly esthetic, metal-free and durable restaurations. Zr-oxide became a common substructure for dental restaurations already quite a while ago. This material features outstanding biocompatibility and mechanical properties Zr-oxide is mechanically machined in its greenstage, taking into consideration the specific shrinkage of this material. The sinterization is optimized for the specific material and its overzised milling relative to the material properties, thus assuring the best possible fit.

Another important factor contributing to a perfect fit is the right choice of support for this to be sintered substructure. Every manufacturer has his own recommendations concerning these supports. Some suggest to sinter on special „pearls“, unfortunately particle size and quality are not always right to by example avoid getiing pinched between the interproximals
and thus distorting the bridge.

Other solutions favour the use of „drops“, resting on very expensive and fragile support discs. The necessary preparations for this type of support are always time consuming, sometimes even cumbersome and allways generating additional costs. A viable alternative are special hi- density and quality sinterization pearls from nt-trading, optimized for crowns and bridges and therefore avoiding the common „pinching“ and distortion problems especially known to bridges.
