| abstract |
The present invention is made from a mixture of a thermoplastic (eg polycaprolactone), a free radical polymerizable resin (eg urethane diacrylate oligomer), and a free radical initiator (eg visible light cured photoinitiator). To a thermoplastic molding composition. The mixture is solid at 38 ° C., has a melting point or softening point that the oral tissue can sufficiently tolerate, and the thermostable custom shape memory and semithermoplasticity can be imparted by molding the composition into a desired shape and then polymerizing the resin. |
