Porcelain crown on metallic support is the most frequent choice.
They are durable and provide good aesthetic results.
The quality-price ratio is excellent.
The price of porcelain crowns is more affordable and they are reliable and have a natural look.
The metal alloy can be chrome-nickel, chrome-cobalt or platinum gold.
Platinum gold is perfectly biocompatible with a highly esthetic finish. On the other hand, the high price makes it a less popular choice.
Chrome-nickel is a non-corrosive composition generally well tolerated by the body. Today, it is less used as a structure for the porcelain crowns due to possible (very unlikely) allergic reaction to nickel.
Due to its high resistance, the non-corrosive composition of chrome-cobalt can be set in thin layers leaving extra space for porcelain. The result is a highly aesthetic porcelain crown. Does not cause allergic reactions.
Teeth with no dental nerve (devitalized) are prone to grinding, cracking or breaking. In order to protect them, we recommend covering them with porcelain crowns. When a tooth is cracked, it can be reconstructed with a filing. But it is quite frequent that the crack line includes a part of the tooth root. In this case, the tooth must be removed. To avoid this unfortunate situation, we recommend that all devitalized teeth are capped.
Molars and premolars are especially strained during mastication. They present the full benefits of durability and strength of porcelain crown on metallic support, since aesthetic considerations are reduced.
In order to find an adequate solution for every case, the metal-ceramic restorative pieces (crowns or bridges) are the durable solution, their price-quality ratio is excellent and they look great. In aesthetic terms, they are superior to all-ceramic and zircon structures.
