alumina, zirconia, and pressable ceramics, including lithium disilicate. Wondergel burns out clean in the furnace and does not leave residue. Wonderpeg has been developed to stabilize veneers, crowns, and bridges during the firing phase. Veneers have always been difficult to fire. For example, if they are set on a pillow material, a fuzzy
The Result of Inspiration . Only if we continuously improve our technology we will be able to keep our place among the best. This is why our developers keep improving our mature and time-proven line of furnaces to provide even better performance and simpler handling.
porcelain, glass ceramic, and now zirconia are the various contemporary materials used for the fabrication of crowns and bridges. Porcelain has color-rendering and optical properties that simulate natural teeth; though these res-torations are considered to be color stable, discoloration is one of the primary factors for failure of esthetic restora-
Enjoy beautiful restoration results while staying within budget with Shenpaz small footprint porcelain firing furnaces. Ideal for new laboratories with limited space or established facilities looking for a cost-effective solution to high-quality firing.
The ten-part Creation CC Bleach Shades Kit contains a base porcelain perfectly matched to the metal framework, three dentines, one incisal and one shoulder porcelain and the corresponding fluids. They are, of course, compatible with all the ceramics contained in the Creation CC system - for individual solutions with impressive colour brilliance.
Dental porcelain (also known as dental ceramic) is a dental material used by dental technicians to create biocompatible lifelike dental restorations, such as crowns, bridges, and veneers. Evidence suggests they are an effective material as they are biocompatible, aesthetic, insoluble and have a hardness of 7 on the Mohs scale.
is removed from the furnace, its outer surface starts contracting and becomes rigid as it loses heat rapidly, while the interior part is still hot and somewhat viscous. The tensile stresses which would normally develop in an elas-tic body during such rapid cooling are relaxed while the interior of the porcelain is above the Tg, or more speciﬁ
Porcelain and Pressing Furnaces. Understanding the dynamics of modern furnaces and ceramic materials can positively affect the esthetic outcome of restorations. By Brad Patrick, BSc. No other tool that ceramists use has a greater effect on the final outcome of a restoration than the porcelain furnace.
Dental furnaces are designed to work with a range of ceramic materials, and some furnaces are designed to also produce the pressure needed to press glass ceramics, and other pressable materials. Many modern dental ovens feature touchscreen controls, pre-set programs and even the ability to connect to the internet.
Porcelain Furnace •C ycles ®for In-Ceram, Wol-Ceram® and CaptekTM • Built for high temperature sintering • Also works great for conventional high and low fusing porcelain cycles Whip Mix porcelain furnaces are built extra tough to withstand the demands of high-temperature porcelain firing, with advanced thermal
