Metal-ceramic dental crowns are the most commonly used crowns in the modern era. They have a frame that’s metallic and it is lined with ceramic. In comparison to plastic or metal crowns, ceramic crowns are much more durable and aesthetic. They also possess a “natural transparency”
But just like the proverbial fly in the ointment, metal-ceramic crowns have their own disadvantages.
They are insignificant, but do need to be mentioned. Over time, the tooth under a metal-ceramic crown undergoes decay and so, the average lifespan of such procedures is about five years. And when the gum sags over time, the metal edge of the crown becomes visible, which doesn’t look very aesthetically pleasing, especially when a person smiles. But if the dentist and the technicians involved perform the installation correctly and ensure that all requisite care is taken, then the crown could last a very long time and offer immense satisfaction to the patient with its attractive and fresh look/appearance.
Zirconium Dental Crowns
The most safe, aesthetic inconspicuous and expensive crowns are metal-free crowns. They are made from Zirconium dioxide or ceramics. In our subjective opinion, today, metal-free zirconium crowns are significantly ahead of metal-ceramic dental crowns across several parameters.
