Dental system for trans-illumination of teeth

摘要

A dental system may transilluminate teeth using a light source for producing examination radiation by directing the examination radiation at a tooth to be examined. An optical image of the tooth illuminated by the examination radiation may be acquired. The light source may include a light-guiding and/or light-deflecting element that faces the tooth to be examined. Light-guiding and/or light-deflecting elements may be embedded in a transparent, flexible coupling body that is provided to rest on the tooth or the gingiva of the tooth.

1. Dental system for the trans-illumination of teeth, comprising:
a light source for producing examination radiation, irradiation means for directing the examination radiation at a tooth to be examined, means for acquiring an optical image of the tooth illuminated by the examination radiation, and a transparent, flexible coupling body configured to rest on the tooth or on a gingiva of the tooth, wherein the irradiation means includes one or more light-guiding elements and one or more light-deflecting elements, wherein at least one of the light-guiding elements is embedded in the material of the transparent, flexible coupling body, wherein the one or more light-deflecting elements comprise one or more deflecting prisms disposed proximate to an end of the one or more light-guiding elements, respectively, on a light-exit side, and wherein a refractive index of the flexible coupling body is different than a refractive index of the light guiding elements and/or the light deflecting elements, and the flexible coupling body includes a light-transmitting structure adapted to deform when pressed against the tooth, the light-transmitting structure comprising a plurality of deformable peaks and a plurality of valleys.
