Dental sintering furnaces are used to process dental zirconia after it has been milled into a crown, bridge, framework or other restoration. These furnaces are capable of reaching the extremely high temperatures required to sinter zirconia to its final hardness. The sintering process, which can involve pressure as well as heat, reduces the porosity and increases the density of ceramic materials such as zirconia. During the sintering process zirconia undergoes a significant amount of shrinkage. When choosing a sintering furnace for your practice or lab it is important to consider its capacity, it's pre-programmed cycles and automation features. With new options for both lab and chairside sintering, producing your own zirconia restorations is faster and easier than ever.
