The system consists of several assortments comprising models and image representations as well as layering diagrams of different tooth forms and tooth color structures. A comparison of form and color between the patient's teeth and the models is then made, whereby the suitable assortment(s) are selected and can be reproduced true to nature in the dental laboratory, using the appertaining layering diagrams. The system according to the invention consists of several components which can be assembled to form a basic assortment.
