What does a metal ceramic restoration consist of?

A metal ceramic restoration, commonly used in dentistry, consists of a substructure made of metal and an overlay of ceramic material. This combination takes advantage of the strength and durability of metals, while also allowing for the aesthetic appeal of ceramic. The metal base provides structural support, which is essential for bridging gaps or covering damaged teeth, while the ceramic provides a tooth-like appearance that blends well with natural teeth.

The layered approach also allows for significant customization in terms of color and translucency, making it an ideal choice for visible areas in the mouth. This dual-material design is particularly beneficial when the restoration is subjected to the forces of chewing, as the metal helps withstand these stresses better than ceramic alone.

When considering the other options, a restoration made of only ceramic would lack the necessary strength for certain applications, while one made exclusively from metal would not provide the natural appearance that patients desire. The choice that includes both metal and ceramic is what enables the benefits of strength and aesthetics to coexist effectively.
