All ceramic or all porcelain crowns are a natural looking, aesthetically pleasing option for restoring teeth that have been seriously compromised and cannot be restored with simple resins.
The procedure for placing all ceramic crowns is similar to any kind of dental crown, it is almost the same as porcelain-fused-to-metal dental crowns (PFMs). However, teeth must meet minimum height and position requirements in order to qualify for crown placement.
As the name states, all ceramic crowns lack the metal core PFMs have. This core is meant to hold the porcelain and it greatly reduces its brittleness. This does not mean that all ceramic crowns will easily break or fail, but it is known that they have low flexural strength and have a tendency to fracture more easily than metal based crowns. On the other hand, ceramic crowns are highly aesthetic and provide a natural look. This is why ceramic crowns are favorites among those concerned with having the perfect smile.
