Dental appliances with improved flexibility, strength, and resistance
A recently granted patent (Publication Number: US11999141B2) discloses a polymeric sheet composition designed for use in dental appliances. The composition consists of a thermoplastic polymer layer with a flexural modulus ranging from 1,000 MPa to 2,500 Mpa, along with an elastomeric layer containing elastomeric material with a hardness between A 80 to D 75. The elastomeric layer can also have a melting point between 90°C to 220°C, providing flexibility and durability to the composition. The overall thickness of the polymeric sheet composition can vary from 250 microns to 2,000 microns, ensuring suitability for various dental applications.
Moreover, the patent claims detail the specific characteristics of the thermoplastic polymer layer, including a glass transition temperature between 100°C to 120°C and a hardness ranging from R100 to R115. The elastomeric layer can be positioned between two thermoplastic polymer layers, with the second thermoplastic polymer layer having similar flexural modulus properties. Additional layers can be added, such as a second elastomeric layer with a hardness of A 60 to D 85 and a third thermoplastic polymer layer. The combined thickness of these layers can range from 100 microns to 750 microns for the polymer layers and 150 microns to 1,000 microns for the elastomeric layers. The composition allows for the creation of dental appliances conformal to teeth, including dental aligners, providing a versatile and customizable solution for dental applications.
