Abstract:
A method of capturing data from a patient's dentition with the steps of positioning a first optical sensor relative to patient's dentition, capturing the shape of a tooth in the patient's dentition, independent from capturing the shape, measuring a color at a location on the tooth, and providing a correlation between the location of the color and a coordinate in the captured shape. The invention helps providing a dental restoration at a relatively high optical, mechanical, and geometric quality.
Abstract:
A system for developing a tooth whitening protocol is provided. The system includes a measuring device for measuring tooth enamel thickness and a measuring device for measuring tooth color. A computing resource includes a processor and a memory storing at least one application executable by the processor. The memory includes one or more data look-up tables including a compilation of scattering and transmission properties associated with specific tooth enamel thicknesses. The processor utilizes the at least one application to approximate tooth dentin based on a measured tooth enamel thickness and measured tooth color to develop a specific tooth whitening protocol.
Abstract:
An intra-oral imaging apparatus for obtaining an image of a tooth has an image capture apparatus with an imaging sensor that is energizable to obtain image data and one or more optical elements for directing light from the tooth to the imaging sensor. An illumination apparatus has one or more light sources energizable to emit light and a spatial light modulator that is configurable to shape an illumination beam from the emitted light. One or more optical elements relay the shaped illumination beam toward the tooth surface. A control logic processor in signal communication with the imaging sensor obtains image data and in signal communication with the spatial light modulator shapes the illumination beam according to the obtained image data.

Abstract:
The invention concerns a system for measuring the colorimeter of objects comprising an illuminating source (SO), a detecting device (CA) supplying electric signals representing the image of the illuminated tooth/teeth. The illuminating source comprises at least three light-emitting diodes (DL1 to DL3) emitting light rays of different and sequentially controlled wavelengths. A central unit (UC) receives, from the detecting device (CA), each time the object is illuminated, the image of the light reflected and received by the detecting device. The central unit computes, for each image, the level of each colour and determines, for different points, standard colorimetric coordinates. The invention is useful for measuring the colour of teeth.
Abstract:
The referencing or calibration phantom (1) has at least a partial surface with at least two different colors or two shades of the same color. The surface is at least partially opaque.
