IEEE-Tristar Composite Multilayer Aligner Sheet

Tristar material has been cited in the IEEE paper

Distributed Force Measurement and Mapping Using Pressure-Sensitive Film and Image Processing for Active and Passive Aligners on Orthodontic Attachments

The aligners were made of Tristar material which is the latest generation of multilaminate materials. It is formulated by combining different layers of thermoplastic polyurethanes, thermoplastic elastomers, and polyethylene terephthalate glycol (PETG). This combination achieves a high elastic limit, low‘creep and flow’, and low force decay throughout the application.
