Disclosed is method for generating a dental preparation guide configured for validating the preparation of at least one tooth for a dental restoration, said method comprising:
a: obtaining a digital 3D representation of a pre-prepared set of teeth;b: virtually removing said at least one tooth from the digital 3D representation of the pre-prepared set of teeth, such that a digital 3D representation of a remaining set of teeth is formed;c: providing a virtual target dental restoration expressing a target shape of the dental restoration;d: creating a virtual validation surface for the dental preparation guide based on the virtual target dental restoration, where the validation surface is such that the preparation of the tooth can be validated by the dental preparation guide; ande: creating a virtual preparation guide surface by combining the virtual validation surface and at least part of the surface of the digital 3D representation of the remaining set of teeth. |
