The high biocompatibility of zirconia will not cause allergies in patients who have allergic reactions to PFM restorations. Zirconia crowns can sometimes cause sensitivity after they have been fitted. The all-ceramic crown is a common restoration method for a broken or cracked tooth. 5. Zirconia crowns are very strong, so they have a very low fracture rate. ( Zirconia is just the generic name of the material. Zirconia crowns can sometimes be difficult to match in terms of colour against your other natural teeth.

Color of zirconia crowns. They may be fabricated from solid full-contour zirconia, high translucent zirconia or layered zirconia. This eliminates the possibility of metal margins becoming exposed due to gum recession. They can also be layered with porcelain to further improve the appearance. The zirconium is popularly known for its strength and durability, which makes it ideal to be used for the production of dental crowns. Quite a few dental patients are allergic to the alloys used for the fabrication of PFM crowns. It can withstand wear and chip.

[1,2] At present, the materials used in all-ceramic crowns mainly include glass-infiltrated alumina-based ceramics, glass ceramics by injection molding, and yttria-stabilized tetragonal zirconia polycrystals (Y-T Tips & Tricks, They are very resistible to high temperatures and, as a rule, dont cause teeth hypersensitivity. Zirconia crowns are comfortable for patients, as they do not transmit hot and cold in the same way as conventional PFMs. The prep should be tapered between 4and 8.

Zirconium crowns also provide strength without that bulky appearance that porcelain is so known for. Zirconia HT(High Translucent), at 590-720 MPa, is much stronger than porcelain-fused-to-metal (PFM) restorations and maintains a natural and vibrant translucency. This, therefore, makes them significantly more costly than traditional crowns and this is one of their major disadvantages. Zirconium crowns are so strong they can be used anywhere in the mouth. Now, however, the newer generation of materials are pre-shaded and can be fabricated to provide highly aesthetic and naturally-perfect restorations with minimal tooth reduction, meeting or even exceeding patient demands for high-quality work!

And it's biocompatible with soft tissue, less invasive preparation for the tooth, it last longer, and of course corrosion resistant. Solid zirconia is also very effective for masking highly discolored dental preps, specifically those that have darkened due to previous dental treatments, such as a post and core or a restored dental implant. Zirconia crowns are highly biocompatible, as the smooth surface helps to reduce plaque accumulation. Clinicians who wish to provide patients with excellent dental restorations often choosezirconiacrowns. Besides crown breakage or failure, porcelain crowns can rapidly wear down opposing teeth if the porcelain surface becomes rough. Zirconia crowns are made of zirconium oxide a light-colored metal.
