Abstract: A method for validating a preparation of at least one tooth in a prepared set of teeth for determining whether the prepared tooth is capable of accepting a dental restoration includes obtaining a virtual dental preparation guide configured for validating the preparation of the at least one tooth; obtaining a digital 3D representation of the prepared set of teeth; visualizing the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth; and validating from the visualization of the virtual dental preparation guide together with the digital 3D representation of the prepared set of teeth whether the prepared at least one tooth is shaped such that it can accept the dental restoration.

Abstract: A method for generating a dental preparation guide configured for validating the preparation of at least one tooth for a dental restoration. A tooth is virtually removed from a digital 3D representation of the patient's pre-prepared set of teeth to form a digital 3D representation of a remaining set of teeth. A virtual target dental restoration expressing a target shape of the dental restoration is obtained and a virtual validation surface for the dental preparation guide is created 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. A virtual preparation guide surface is created by combining the virtual validation surface and part of the surface of the digital 3D representation of the remaining set of teeth.

Abstract: A 3D scanner system includes a scanning device capable of recording first and second data sets of a surface of an object when operating in a first configuration and a second configuration, respectively. A measurement unit is configured for measuring a distance from the scanning device to the surface. A control controls an operation of the scanning device based on the distance measured by the measurement unit, where the scanning device operates in the first configuration when the measured distance is within a first range of distances from the surface and the scanning device operates in the second configuration when the measured distance is within a second range of distances; and a data processor is configured to combine one or more first data sets and one or more second data sets to create a combined virtual 3D model of the object surface.
