Abstract:
1. A computerized method for reconstructing data associated with an obscured finish line using a computer system, comprising: (a) providing to a computer processor, data of a 3D virtual model of at least a portion of an intraoral cavity comprising a preparation having a finish line, the finish line defining a transition boundary between the preparation and a prosthesis that may be mounted with respect to the preparation, wherein at least a portion of the finish line is obscured; and configuring the computer processor to: (b) manipulate said data of said 3D virtual model in a vicinity of said obscured portion of said finish line in a virtual manner to create an auxiliary 3D virtual model that is displayable on a computer screen and corresponds to said obscured portion of said finish line, and (c) provide topographical data of the finish line from the 3D virtual model and the auxiliary 3D virtual model to reconstruct data of the obscured finish line.
