METAL

Metal crowns generally make use of gold alloys or base metal alloys like that of chromium or nickel.

If compared to the other crown types with metal, minimal amount of tooth structure has to be removed and wearing out of adjacent teeth is also minimal.

Since these crowns are made of metals, they can withstand chewing and biting forces well and last for over a very long period. They hardly break or chip off.

ADVANTAGES :

• The most significant advantage of metal crowns is their tremendous strength.
• Crowns made completely of gold are of very good quality.
• Cause minimal wearing of the surrounding teeth as compared to others.
• Require very little amount of filling for the tooth.
• Last for a very long period and resist chipping and breaking better than other types of crown.
• They are very durable and are used for the restoration of hidden teeth.
• Best suitable for patients who have strong chewing habits and are likely to clench and grind their teeth often. 

DISADVANTAGES

• The only main disadvantage is their metallic appearance.
