What materials are commonly used for indirect restorations?

Indirect restorations typically involve the use of durable materials that can withstand the functional demands placed upon them in the oral environment. Ceramics, porcelain fused to metal, and gold are among the most popular choices due to their aesthetic qualities, strength, and biocompatibility.

Ceramics are particularly valued for their natural tooth-like appearance, making them ideal for dental crowns, inlays, and onlays. Porcelain fused to metal combines the strength of metal with the aesthetic benefits of porcelain, providing both durability and a tooth-like appearance. Gold is also a traditional material used in indirect restorations because it is highly biocompatible and can withstand significant occlusal forces, making it suitable for posterior teeth where wear is a concern.

While other materials like composites and glass ionomer do have their uses in dentistry, they are generally not considered as reliable for indirect restorations when compared to the strength and longevity provided by ceramics, metal, and gold. Therefore, they are more commonly used for direct restorations and certain other applications rather than for indirect restorations that require robustness and durability.
