The present invention relates to a method of and an arrangement for generating a three-dimensional computer model of a tooth restoration (50) or a part thereof where the computer model is intended to be used in a manufacturing process of said restoration (50). The method comprises the steps of: storing information representing the external shape of a preparation (2), generating a computer model of the preparation (2), registering and/or storing at least one value of at least one restoration parameter (h1, h2, h3, h4, h5, g1, g2) defining the location of the restoration (50) in relation to the location of the preparation (2) in a configuration consisting of the restoration (50) and the preparation (2), where said preparation (2) comprises a margin (4), and using the at least one registered and/or stored value of the at least one restoration parameter (h1, h2, h3, h4, h5, g1, g2) for the generation of the computer model of the restoration (50). |
