Full metal crowns are dental restorations that are used to replace the visible portion of a tooth, known as the “crown.” They are made entirely of metal, and can be fabricated from different types of alloys, including precious, semi-precious, and non-precious alloys.
Precious metal alloys, such as gold alloy, are the most commonly used for full metal crowns. They are biocompatible, have high resistance to wear and tear, and provide good aesthetics with a natural-looking gold color.
Semi-precious metal alloys, such as palladium alloy, are also used for full metal crowns. They provide good strength, wear resistance and esthetics, also offer the benefits of being biocompatible.
Non-precious metal alloys, such as chrome cobalt alloy, are also used for full metal crowns. They are known for their high strength and durability, and are often used in areas of the mouth that experience heavy chewing forces, such as the molars. They can also be easily polished to a high shine and are often used in situations where esthetic is not the main concern.
Full metal crowns are highly durable and long-lasting, making them a suitable option for patients who have experienced tooth decay, trauma, or other issues that can compromise the integrity of a tooth. However, their metallic appearance is not as natural as tooth-colored options like porcelain fused to metal or all-ceramic.
