Abstract

L'invention concerne un procédé de fabrication d'un appareil orthodontique utilisé dans les laboratoires dentaires ou directement au cabinet dentaire. La présente invention a pour but de permettre, en variante des procédés classiques, une nouvelle approche des soins d'orthodontie optimisés, spécifiques au patient mais rentables et efficaces. Le but est atteint par la réalisation d'appareils amovibles à l'aide d'un procédé d'impression 3-D assisté par ordinateur sur la base d'un scanner buccal. Notamment, dans la mise en œuvre technique, il est intéressant de pouvoir effectuer un transfert universel à des procédés d'impression à poudre et résine pour générer des géométries tridimensionnelles quelconques. Une nouvelle caractéristique de l'invention est que, contrairement à l'art antérieur, il n'est pas nécessaire de réaliser une forme en négatif. Le procédé d'impression avec une imprimante 3D ou la mise en forme avec une fraiseuse à commande numérique permet de fabriquer l'appareil orthodontique en tant qu'original.
