Abstract
A method of forming an orthodontic aligner comprises: generating a teeth digital model; generating a digital dental model based thereon; assigning an identifier to the digital model; forming a dental model, marked with the identifier, corresponding to the digital model; coding a RFID chip within a pallet with the identifier; placing the dental model upon the corresponding pallet, based on the identifier, to form a model/pallet pair; placing the model/pallet pair into a model/pallet vessel; placing a biocompatible thermoplastic sheet upon a membrane stretched about a pressurizable chamber; heating the thermoplastic sheet; placing the membrane and the heated sheet adjacent the model/pallet pair; pressurizing the chamber to apply pressure to the membrane to form the sheet onto the model to form a molded aligner sheet; and cooling the molded aligner sheet to form the orthodontic aligner. The membrane creates a physical barrier between the applied pressure and the sheet.
