What is a common type of dental crown material?

Porcelain-fused-to-metal (PFM) crowns are a common type of dental crown material due to their durability and aesthetic appeal. This type of crown consists of a metal base that provides strength, which is then covered with a layer of porcelain to enhance its appearance. The combination of materials allows for the crown to withstand significant biting forces while mimicking the natural color and translucency of teeth, making it suitable for both anterior and posterior restorations.

The versatility of PFM crowns makes them a preferred choice among dental practitioners, especially for patients who require a balance between functionality and aesthetics. Their ability to blend seamlessly with the surrounding teeth contributes to a natural look, while the underlying metal provides the necessary strength for long-lasting performance in areas subject to chewing pressure.

While ceramic, resin, and glass ionomer materials are also used in dental crowns, they possess unique properties and indications for use. Ceramic crowns, for instance, offer excellent aesthetics but may not be as strong as PFM. Resin crowns are often used for temporary restorations due to their ease of use and lower cost, but they may not provide the same longevity as PFM. Glass ionomer is generally used for fillings and not as commonly for crowns due to its lower strength and aesthetic qualities.
