| description | Disclosed are a method and a respective apparatus of forming an orthodontic aligner from an aligner digital model. The method comprises the steps of three-dimensionally printing an intermediate structure comprising fused filaments from a biocompatible thermoplastic, coating the intermediate structure with a biocompatible translucent photopolymer and irradiating the coating with ultraviolet light to cure the coating on the intermediate structure, thereby forming the orthodontic aligner. Said orthodontic aligners may be expeditiously formed directly from aligner digital models, without requiring the fabrication of dental casts to thermoform the aligners on the dental casts. A method of forming an orthodontic aligner with a pre-cut aligner sheet by defining a virtual edge of the aligner is further disclosed. A method of forming an orthodontic aligner from an aligner digital model comprising the steps of forming an injection mould and injection moulding a thermoplastic into the injection mould is also disclosed. |
