As chairside CAD/CAM dentistry continue to expand its reach, a range of new restorative materials are available for use in the dental clinic. While full-contour zirconia restorations are a rapidly growing option, the production of these restorations chairside is still uncommon. Fabricating a zirconia crown requires a mill capable of cutting the hard ceramic material and a specialized furnace to sinter it. In the past this sintering took extremely long periods of time, but now it can be accomplished in time frames similar to that of more popular chairside ceramics. Production of full-contour zirconia crowns chairside might not be common today, but it might be in the future, and with that in mind, here is a look at some of the specialized sintering furnaces for use with zirconia restorations.
