Abstract

La présente invention concerne un procédé de déplacement d'une dent au moyen d'un scanner buccal et d'une imprimante tridimensionnelle qui comprend les étapes de : balayage, par le scanner buccal, de la cavité buccale d'un patient; exécution, par un terminal dentaire, d'une correction au moyen des données buccale scannées; transmission, par un serveur, des données orthodontiques corrigées du patient à l'imprimante tridimensionnelle et génération et délivrance en sortie, par l'imprimante tridimensionnelle, d'un modèle orthodontique; génération, par une machine de moulage sous vide, d'un appareil dentaire transparent par pressage sous vide d'une plaque de résine synthétique transparente sur le modèle orthodontique généré; et revêtement de silicone transparent sur une partie au niveau de laquelle l'appareil dentaire transparent est en contact avec les gencives et les dents. Selon un mode de réalisation de la présente invention, un ensemble de données orthodontiques numériques précisément prédites peut être généré en reflétant les caractéristiques d'un patient. De plus, l'appareil dentaire peut être solidement fixé aux dents et aisément fixé aux dents avec le silicone transparent revêtu à l'intérieur de la plaque synthétique, de manière à augmenter un effet orthodontique et protéger les gencives.
