Self-curing acrylic resin is one of the two most common materials used for creating custom provisional coverage.The other is the composite provisional material that is supplied in a syringe as a self-cured,auto-cured,and dual-cured type.
Because of the bulk of material necessary,which would require additional time to polymerize,a light-cured resin is not recommended.
Polycarbonate shells should not be used in posterior stress-bearing areas; thus,they have limited use.
Alginate is an impression material,not a provisional coverage material.
