·Dry the framework in an open furnace for a minimum 6-8 min. depending on size and number of units. ·Bench cool. Opaque should exhibit a glossy finish. D. Wax-up for Pressing: Prior to waxing over the metal framework, weigh the framework and write it down. After completion of the waxup and spruing process, weigh again. Subtract the difference.
After Patrick Boche, Technical Manager at Creation Willi Geller, had given a theoretical introduction to the material zirconium, the participants in the two-day course set to work themselves on an anterior crown with Creation ZI-F. The staining technique with the pressable ceramic Creation CP ZI was next on the programme.
In the ceramic furnace, the special material completely hardens and thereby stabilises the dental technician's work during the firing process - a secure stand including for inlays, onlays, crowns and veneers. Tough yet easy to remove: After firing, the hardened paste can be quickly and completely removed under running water by using an
The optimal pressable ceramic system (Opc, Jeneric Pentron, USA) is a new product designed to press restorations using leucite reinforced ceramics in a press furnace that doubles as a conventional porcelain furnace. The investing, burnout and pressing cycles are similar to the Empress system and restorations are finished in an identical fashion.

Product Questions: What is an RTV Silicone? An RTV (Room Temperature Vulcanization) silicone sealant is a sealant that begins to cure immediately upon being exposed to air (specifically the moisture present in the air), as opposed to water based sealants such latex.
The new variation of the furnace, Multimat Cube press, is also suitable for processing pressable ceramics - for example, for the popular high-strength glass ceramic Celtra Press. First of all, the Multimat Cube and Multimat Cube press deliver exactly what every experienced dental technician expects of them.
Pentron Ceramics offers through Zahn Dental a full line of value-priced quality dental ceramics to meet the needs of dental laboratories worldwide. The Pentron brands provide exceptional shade matching capabilities using opacity units as a guide and superior handling to the ceramists.
