Zirconia Crown & Bridge
•Zirconia strengths are comparable to metal.
•Zirconia is crack resistant, and undergoes a phenomenon called "transformation toughening"
•Zirconia's strength allows traditional PFM preparation design
•coping thicknesses can be as little as 3/10ths in the anterior resulting in:
A. A need for less tooth reduction, or
B. Increased room for esthetic porcelain
•Zirconia translucency is similar to natural dentin.
•Zirconia is insoluble, which is important in regards to long-term strength
•Fits are similar or better than metal
•Being metal free, esthetics are naturally much better than PFM's
