Abstract

Procédé et dispositif de fabrication d'une prothèse dentaire complète sur la base d'une exploration de données et qui concerne le domaine de la médecine buccale. Le procédé de fabrication d'une prothèse dentaire complète consiste à : acquérir des données relatives à la crête alvéolaire d'un patient édenté (101) ; sélectionner, en fonction des données relatives à la crête alvéolaire, un modèle de prothèse cible dans une base de données de modèles de prothèses dentaires complètes (102) ; et l'acquisition de données de conception de prothèse dentaire complète selon le modèle de prothèse cible et les données relatives à la crête alvéolaire (103). Au moyen de ce procédé, des données relatives à la crête alvéolaire d'un patient peuvent être mises en correspondance avec des données d'un modèle de prothèse dentaire standard dans une base de données de modèles de façon à obtenir un modèle de prothèse dentaire standard approprié pour le patient. Sur la base de ce modèle, la conception complète de la prothèse dentaire est en outre effectuée de façon à omettre l'étape au cours de laquelle un technicien effectue une conception et une fabrication manuelles détaillées, ce qui permet d'améliorer le degré d'automatisation de la conception de prothèses dentaires complètes et d'améliorer l'efficacité de la fabrication de prothèses dentaires complètes.
