An example of the reverse engineering of the virtual reference master model image and virtual test model image before accuracy evaluation. a Virtual reference master model image. b Virtual test model image. c A virtual scan body with the parametric implant design was used for reverse engineering. d Virtual scan bodies with the virtual implants were superimposed against the virtual reference master model image. e Virtual scan bodies with the virtual implants were superimposed against the virtual test model image. f The reconstructed master model image with the implants after removal of the irrelevant surfaces. g The reconstructed test model image with the implants after removal of the irrelevant surfaces. h The remaining virtual implants were superimposed to measure the deviations between the 2 models
