Abstract
An orthodontic appliance including at least one orthodontic component comprising a thermoplastic polymer. In some embodiments the thermoplastic polymer is a rigid backbone polymer including at least one of a compatibilizing side roup or a solubilizing side group. The thermoplastic polymer may be heat processed to form the orthodontic component.
Claims32
An orthodontic component, comprising a rigid backbone polymer, the rigid backbone polymer at least partially comprising a first arylene or heteroarylene moiety joined to a second arylene or heteroarylene moiety by a covalent bond between adjoining ring carbon atoms of the arylene or heteroarylene moieties.
An orthodontic component, comprising a thermoplastic polymer and without a reinforcing agent, wherein the thermoplastic polymer has a tensile strength of at least about 150 MPa and a tensile modulus of at least about 4 GPa.
An orthodontic component, comprising a thermoplastic polymer, wherein the thermoplastic polymer has an unreinforced tensile strength of at least about 150 MPa and an unreinforced tensile modulus of at least about 4 GPa.
