| titleOfInvention | A spectrum-photometer device for exactly determining the colour of a dental plate and of dental pluggings |
| abstract | Device for determining exactly the color of a dental prosthesis to be placed, or of the material to be used in the fillings of dental cavities, so as to make them perfectly identical to the color of the patient's teeth. It comprises a light source (1) emitting light rays on a monochromator (2), which, using an optical switch or chopper (3), separates the monochromatic light rays into at least two parallel circuits. (4, 4a, 5, 5a), one (4, 4a) comprising a housing or cell (6) for at least one of the patient's teeth (9), the other (5, 5a) comprising a control cell (7) containing a control sample (28) of white color. Said circuits result in a device (8) which detects and compares the rays coming from the cell (7) and those which have passed through the cell (6) and the tooth (s) (9), providing a sequence of signals which are applied to a detector (8), then duly amplified and applied to an analog-to-digital converter (12) connected to a data processor or computer (10), which provides the coded identification data relating to the color identified. |
