What type of dental material is used in making a custom provisional?

Amalgam
Acrylic resin
Gold alloy
Silver filling

The correct answer is: Acrylic resin

Acrylic resin is the most commonly used material in making custom provisionals because it can be easily shaped and adjusted to fit the individual patient's teeth and it is also strong enough to withstand chewing and other daily activities. Amalgam is typically used for permanent fillings but is not suitable for temporary provisionals. Gold alloy is a more expensive material that is typically used in permanent restorations, not temporary provisionals. Silver filling is another common material used for permanent fillings but is not suitable for custom provisional restorations. In comparison, acrylic resin is the best option for making customized provisionals due to its versatility and strength.
