Xircon Ultra uses modern technology combining materials that have a long track record of both beauty and durability, these are used by a large number of facilities around the country. Most full arch bridges (All on 4/6) are made using a titanium bar covered with PMMA (Acrylic). The other option is Monolithic Zirconia (the whole bridge is milled out of one piece of Zirconia), the issue with these options is that the PMMA is not durable enough and it tends to stain overtime, and the Zirconia usually is stiff, heavy, and when it breaks it is not repairable, thus causing the patient to have to pay for a whole new appliance. Also, it is much more difficult to achieve high end esthetics (due to less translucency) with those options. Xircon Ultra uses advanced polymers as a base instead. These polymers are lightweight, strong, biocompatible, easily maintained, do not stain, and have a similar flexure to that of natural bone. These polymers have been used for many years by orthopedic surgeons to fabricate prosthetics, due to its bone-like properties and bio-compatibility. Also, the density of these polymers is very close to that of dentin (the natural materials that make up your natural teeth), thus the result is a perfect balance between structural rigidity, beautiful natural look, and comfort.
