Advantages of Metal Crowns

Metal crowns offer a range of advantages that make them a popular choice for dental restorations. Various metals such as gold, platinum, palladium, cobalt-chromium, and titanium used in metal crowns achieve exceptional durability, longevity, biocompatibility, and corrosion resistance. 

What metals are commonly used in metal crowns?

Some of the main metals used in metal crowns include:

Gold (Au): Gold crowns are highly biocompatible and well-tolerated by oral tissues, which reduces the risk of allergic reactions or tissue irritation. 

Platinum (Pt): Platinum crowns exhibit exceptional corrosion resistance, which contributes to the overall durability and reliability of platinum crowns in dental restorations.

Palladium (Pd): Palladium crowns provide good durability and resistance to wear while also delivering a natural-looking appearance that blends well with adjacent teeth.

Cobalt-Chromium (Co-Cr): Cobalt-chromium crowns are renowned for their exceptional strength and hardness. They can withstand significant chewing forces without fracturing or deforming.

Titanium (Ti): Titanium crowns offer excellent biocompatibility and corrosion resistance. They are also lightweight and strong, providing durability and longevity in dental restorations.

What are the key advantages of a metal crown?

Metal crowns hold several key advantages over other crown types, including:

Strength and durability: Metal crowns exhibit exceptional strength and resilience against mechanical stresses. This makes them particularly suitable for restoring posterior teeth that are subjected to substantial chewing forces. A metal crown is typically stronger than ceramic alternatives, and also generally exhibits higher flexural strength. This makes them more resistant to bending or deformation under stress.
