What is an all ceramic crown?
What are the different types of all-ceramic crowns?

What are the different types of dental ceramics?
Classification based on processing technique But, in general, for dentistry, they can be classified as: Powder/liquid, glass-based systems, machinable or pressable blocks of glass-based systems and. CAD/CAM or slurry, die-processed, mostly crystalline (alumina or zirconia) systems.
What is full crown restoration?

This eliminates the need for porcelain (or some other ceramic material), which is not as durable as gold, and it also has the esthetic advantage of maintaining natural tooth structure.
What is all-ceramic crown preparation?
When preparing teeth for all-ceramic crowns, a uniform reduction will help result in optimal ceramic strength. Ensuring sufficient tooth structure is removed will lead to better aesthetics. The smoother the edges, the lower the stresses placed on the porcelain crown which in turn decreases the potential for fracturing.
What material is used for ceramic?
