Abstract:
A 3D measurement of teeth occurs while exciting fluorescence in the volume of the teeth. To this end, use is made of suitable radiation which, as a result of the fluorescence, is therefore strongly absorbed. As a result of this, the problem of translucence when measuring teeth is significantly reduced.
