Claim One:
1. A process for the design of a dental appliance for a facial skeleton of a patient comprising a mandibular and a maxillar dental arch, the process comprising the following steps: providing a 3D digital model of said mandibular and maxillar dental arches; obtaining reference planes of the facial skeleton by pointing characteristic points of the patient's face with a stylus tracked by a motion capture camera; attaching markers to the mandibular arch and to the patient's head, wherein the markers are distinct from the stylus; correlating the 3D digital models of the mandibular and maxillar dental arches with the reference planes of the facial skeleton by pointing with the tracked stylus, in the patient's mouth, corresponding points of the models of the dental arches; registering the 3D digital models of the mandibular and maxillar dental arches with the markers; recording displacements of the mandible with respect to the maxilla of the patient by tracking the markers by the motion capture camera; moving the model of the mandibular dental arch with respect to the model of the maxillar dental arch by applying said recorded relative displacements of the mandible and the maxilla to the models of the mandibular and maxillar dental arches.
