Abstract

A computer-implemented method for detecting tooth cracks on a digital 3D model (501) of a dental situation is disclosed. The method comprises receiving the digital 3D model (501) of the dental situation, generating an input (301, 401) for a trained neural network (300, 400) for tooth crack detection, wherein the input (301, 401) comprises at least a part of the digital 3D model (501) with associated color information. The method further comprises detecting a tooth crack (100) on the at least part of the digital 3D model (501) by applying the trained neural network (300, 400) to the generated input (301, 401). Further, the method comprises determining a severity level of the detected tooth crack (100) based on fluorescence information associated with the at least part of the digital 3D model (501) and displaying the at least part of the digital 3D model (501), the detected tooth crack (100) and the severity level of the detected tooth crack (100).
