45065CAN6A ABSTRACT OF THE DISCLOSURE Thermoplastic molding compositions are made from a mixture of thermoplastic material (for example, polycaprolactone), a free-radically polymerizable resin (for example, a urethane diacrylate oligomer), and free-radical initiator (for example, a visible-light cure photoinitiator). The mixture is solid at 38°C, has a melting or softening point that comfortably can be withstood by oral tissues, and can be imprinted with a heat-stable custom shape memory and semi-thermoplastic properties by shaping the composition to a desired shape and then causing or permitting the resin to undergo polymerization.
