A method and system for selecting dental constructions using translucent materials that match an individual's preexisting tooth appearance uses a set of reference templates. The reference templates are constructed from layers of various translucent dental materials positioned on bases constructed from actual or simulated tooth structures. The layers of translucent materials have a thickness that varies in increments that correspond to the likely thicknesses of the materials when used in dental constructions. A reference table is created based upon color measurements of each of the reference templates. A color measurement of the individual's preexisting teeth is then compared to the reference table to determine which particular dental construction will most closely match the individual's preexisting teeth.

L'invention concerne un procédé et un système permettant de sélectionner des constructions dentaires dans lesquelles sont utilisés des matériaux translucides adaptés à la teinte de la dent pré-existante chez un individu, sur la base de modèles de référence. Ces modèles de références sont constitués de couches de divers matériaux dentaires translucides disposées sur des bases constituées de structures dentaires naturelles ou synthétiques. Les couches de matériau translucide ont une épaisseur qui varie progressivement, chaque variation correspondant aux épaisseurs probables des matériaux utilisés dans les constructions dentaires. Un tableau de références est créé sur la base de mesures de teintes de chacun des modèles de référence. Une mesure de la teinte de la dent pré-existante chez l'individu est ensuite comparée au tableau de référence pour déterminer quelle construction dentaire donnée sera la plus adaptée à la dent pré-existante de l'individu.
