Abstract

Dispositif pour déterminer exactement la couleur d'une prothèse dentaire à poser, ou bien du matériau à utiliser dans les obturations de cavités dentaires, de manière à les rendre parfaitement identiques à la couleur des dents du patient. Il comporte une source lumineuse (1) émettant des rayons lumineux sur un monochromateur (2), lequel, à l'aide d'un commutateur ou d'un hacheur optiques (3), sépare lea rayons lumineux monochromatiques en au moins deux circuits parallèles (4, 4a, 5, 5a), l'un (4, 4a) comprenant un logement ou cellule (6) pour au moins une des dents du patient (9), l'autre (5, 5a) comprenant une cellule témoin (7) renfermant un échantillon témoin (28) de couleur blanche. Lesdits circuits aboutissent à un dispositif (8) qui détecte et compare les rayons provenant de la cellule (7) et ceux qui sont passés à travers la cellule (6) et la ou les dent(s) (9), fournissant une séquence de signaux qui sont appliqués à un détecteur (8), puis dûment amplifiés et appliqués à un convertisseur analogique-numérique (12) connecté à un processeur de données ou un ordinateur (10), lequel fournit les données d'identification codée relatives à la couleur identifiée.
