How durable are the materials used in dental restorations?

Materials used in dental restorations have varying degrees of durability:
  • All-porcelain (ceramic): Brittle material, may fracture under heavy biting loads. Strength depends greatly on quality of bond to underlying tooth structure.
  • Porcelain fused to metal: Very strong and durable.
  • Gold alloys (high noble) and base metal alloys (non-noble): High corrosion resistance prevents tarnishing; high strength and toughness resist fracture and wear.
