Used during the production of ceramic dental restorations such as crowns, bridges, inlays and onlays, dental ceramic ovens employ high temperatures and pressures to process ceramic materials into a hardened, final state. Also called furnaces, these systems are used with both CAD/CAM milled restorations as well as with glaze systems that add a final esthetic polish. 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. When purchasing a furnace for your dental practice or lab it is important to make sure it is capable of processing the materials you plan to work with.
