  • METHOD AND APPARATUS FOR SELECTING NON-OPACIOUS DENTAL MATERIALS
    Publication number: 20080090197
    Abstract: 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 individuals preexisting teeth.
