While a crown is being manufactured in the laboratory, the dentist will need to fit a temporary crown. Which material is not typically used in temporary crown construction?

The material that is not typically used in temporary crown construction is chrome cobalt. This metal is primarily used in the fabrication of permanent restorations and frameworks for dentures due to its strength and durability. In contrast, the materials commonly employed for temporary crowns, such as polycarbonate, resin, and aluminum, are chosen for their ease of use, aesthetic qualities, and lower cost.

Polycarbonate and resin materials are popular options for temporary crowns because they can be easily shaped and adjusted to fit the patient's tooth, offering a more natural appearance compared to metal options. Aluminum might also be used in some temporary crown situations, particularly for anterior teeth, because it provides a lightweight and quick-to-fabricate solution.

In summary, chrome cobalt is not used for temporary crowns as it is not conducive to the short-term, easily removable nature that temporary restorations require.
