Aesthetic dentures are highly individual products, needing to adapt to the patient’s natural dentition in both color and shape. In general, dentures are geometrically complex structures, consisting of several layers of different materials, which are applied consecutively. This is why efforts are being made to introduce additive manufacturing into the production process of aesthetic dentures which is to date largely based on manual work of skilled professionals. In order to successfully apply additive manufacturing accurate models of the denture to be produced are essential. In this paper the layer arrangements of dental crowns from real patient cases are analyzed. Different approaches, based on spherical coordinates, paraxial rays and normal vectors, are compared to each other. Furthermore, a strategy to transfer the knowledge about layer properties from these analyses to future patient cases, in which the geometry might be slightly different but a similar optical impression is desired, is pointed out.
