Abstract

La présente invention concerne un dispositif et un procédé de gestion de traitement orthodontique transparent, le dispositif comprenant : une unité d'apprentissage destinée à générer un modèle de recommandation de plan de traitement orthodontique par apprentissage d'un plan de traitement orthodontique établi sur la base de données de dents de multiples patients cibles d'apprentissage qui ont achevé un traitement orthodontique et de résultats de traitement orthodontique pour chaque étape orthodontique ; une unité de réception destinée à recevoir des données de dents et un plan de traitement orthodontique du patient cible orthodontique obtenu à partir d'un terminal hospitalier ; une unité de recommandation de plan de traitement qui établit un plan de traitement orthodontique recommandé pour les données de dents du patient cible orthodontique sur la base du modèle de recommandation de plan de traitement orthodontique, et qui vérifie le plan de traitement orthodontique reçu sur la base du plan de traitement orthodontique recommandé pour établir un plan de traitement orthodontique final ; et une unité de génération de modèle de dent, qui génère un modèle de dent pour chaque étape orthodontique incluse dans le plan de traitement orthodontique établi et transmet celle-ci à un dispositif de fabrication d'entretoises transparentes.
