Facial scan in “X-ray mode” and after insertion of a virtualized 3D plaster model using the “normal inversion” to simulate the maxillary dentoalveolar arch position (top right). The mandibular dentoalveolar arch was positioned once according to the simultaneous registration (bottom left) after alignment of the virtually inverted maxillary impression model to the virtually inverted mandibular impression model (top left) using the occlusion points in maximal intercuspation
