A system produces orthodontic aligners by CNC machining. A digital model of the patient's dental anatomy (26) is manipulated using CAD software (22) to create a solid CAD model (30) of an aligner. A CNC milling machine (28) is then used to machine the inside (42) and outside surfaces of the aligner (70) from a block (40) of suitable material. A progressive series of aligners can also be designed.

L'invention concerne un système qui produit des dispositifs aligneurs orthodontiques par usinage CNC. Un modèle numérique de l'anatomie dentaire (26) du patient est manipulé en utilisant le logiciel de CAO (22) pour créer un modèle de CAO plein (30) d'un aligneur. Une machine fraisage CNC (28) est alors utilisée pour usiner les surfaces intérieure (42) et extérieure de l'aligneur (70) à partir d'un bloc (40) de matériau approprié. Une série progressive d'aligneurs peut également être conçue.
