摘要： A dental appliance for positioning a patients teeth includes a polymeric shell with a plurality of cavities for receiving one or more teeth. The polymeric shell includes at least 3 alternating polymeric layers AB, wherein layer A includes a thermoplastic polymer A, layer B includes a thermoplastic polymer B, and the thermoplastic polymer B is different from the thermoplastic polymer A. Each of the thermoplastic polymers A and B have a flexural modulus of about 1.0 GPa to about 4.0 GPa; and each of the thermoplastic polymers A and B have a glass transition temperature (Tg) greater than about 40° C.
