Are PFM crowns still used?
PFM Restorations Have Been Used for Decades Since then, PFM has been used successfully in dentistry for the fabrication of dental crowns and bridges. The fact that PFM restorations have been around for so long show that they are a dependable choice for restoration fabrication.

Is eMax stronger than zirconia?
Layered Zirconia, because even the weakest form of translucent zirconia is twice as strong as Emax.
Are zirconia dental crowns safe?
In fact, zirconia possesses excellent biocompatibility, making the crowns and bridges prepared from zirconia extremely safe for clinical use inside the mouth. Advantages of Choosing Zirconia Crowns Zirconia crowns are highly biocompatible, as the smooth surface helps to reduce plaque accumulation. Layered zirconia crowns are extremely durable.
What are purepure zirconia crowns and why are they popular?
Pure zirconia crowns are very popular for that type of situation because these patients could break up restorations (including emax restorations) with their grinding and clenching. They are in need of extreme strength with these restorations. In the past, all these patients could use was metal on the surface.

EMax can be used as a core material whereby porcelain can be layered on the surface to increase the esthetic value of restoration for anterior eMax restorations. Zirconia is an interesting type of crown that has been used for the past eight to ten years continues to be used today. Most people know the phrase “cubic zirconia.”
What are zirconia crowns made of?
They may be fabricated from solid full-contour zirconia, high translucent zirconia or layered zirconia. High translucent zirconia and layered zirconia can be either screw-retained or cemented. Most dental practices are switching from the conventional PFM crowns and moving towards the use of zirconia for creating fixed dental restorations.
