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.
Claims10
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, said method comprising:
- 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.
The method according to claim 9, wherein the virtual preparation guide surface is created by
- virtually connecting a virtual minimum preparation surface and the digital 3D representation of the remaining set of teeth;
- or
- at least in part by a Boolean addition of the digital 3D representation of the remaining set of teeth and the virtual validation surface.
