Crowns can be either single or combined with each other in a bridgework. Single crowns, in turn, can be made of the following materials:
|Metal ceramics||Strength, high aesthetic qualities, affordable price.|
Less aesthetic than metalless.
Larger amount of enamel sewing is required.
|Metal-free ceramics||Virtually indistinguishable from natural teeth due to transparency, there is no metal in the composition, strength, durability, less likelihood of chipping.||Relatively high cost.|
|Metal||Strength, low cost, durability.||Low aesthetic and operational qualities.|
|Metal plastic||Low cost, acceptable aesthetic properties.|
May cause allergies, short service life,
The patients who are most concerned about aesthetic and operational qualities choose metal-free ceramic crowns, and the optimum ratio of price and quality is metal-ceramic.
If prosthetics of both the front and chewing teeth is required, then the best choice at an acceptable cost would be metal-free crowns on the front teeth and metal-ceramic teeth on the chewing ones.
Metal-plastic is usually used for temporary prosthetics.
