Patent ID: 8359115

Claim:
A computerized method for manipulating a virtual dental model, comprising: providing to a computer processor a 3D virtual model of a dental site comprising dental surfaces, wherein a first portion of the dental site is obscured by a material; and executing instructions causing the computer processor to: separate the 3D virtual model into a first virtual model part corresponding to an unobscured portion of the dental site and a second virtual model part corresponding to the first portion of the dental site obscured by the material; generate an auxiliary 3D virtual model comprising an unobscured first portion of the dental site by providing topographical data of the first virtual model part and the second virtual model part so as to reconstruct data of the first portion of the dental site to exclude the material; and generate a reconstructed 3D virtual model of the dental site based on the first virtual model part and the unobscured first portion.
