Abstract
Improved dental appliances and polymeric sheet compositions are disclosed. The polymeric sheet compositions are useful for making dental appliances having outer layers comprised of a material having a modulus of from about 1,000 MPA to 2,500 MPA ('hard') and an inner core comprised of elastomeric material or materials having a modulus of from about 50 MPa to 500 MPa ('soft'), which exhibit improved flexibility and strength, and better stain and tear resistance than currently available materials and dental appliances.
