3D INTRAORAL SCANNER MEASURING FLUORESCENCE

摘要

Disclosed is a 3D scanner system for detecting and/or visualizing cariogenic regions in teeth based on fluorescence emitted from the teeth, said 3D scanner system including a data processor configured for mapping a representation of fluorescence emitted from the teeth onto the corresponding portion of a digital 3D representation of the teeth to provide a combined digital 3D representation.

主权项

1. A 3D scanner system for detecting and/or visualizing cariogenic regions in teeth based on fluorescence emitted from said teeth, said 3D scanner system comprising:
an illumination unit capable of providing probe light for illuminating the teeth, where said probe light comprises light at a first wavelength which is capable of exciting a fluorescent material of the teeth; an image sensor for recording images of light received from the illuminated teeth, where said image sensor is capable of detecting fluorescence emitted from said fluorescent material when said fluorescent material is excited by light at said first wavelength; a data processor configured to:
i. create a digital 3D representation of 3D topography of the teeth based on recorded images comprising the probe light reflected from the teeth;ii. create a representation of the fluorescence emitted from the fluorescent material of the teeth based on recorded images comprising the emitted fluorescence, andiii. map the representation of the emitted fluorescence onto the corresponding portion of the digital 3D representation of the teeth to provide a combined digital 3D representation; and a visual display unit on which the combined digital 3D representation is visualized.
