The present invention generally relates to an apparatus and method for positioning a maxillary dental arch model (13) in a dental articulator to simulate the positioning of a maxillary dental arch represented by the arch model. The arch model may be positioned on a plate (14) having a substantially planar surface with a fulcrum point (20) through which three generally mutually perpendicular axes are aligned. In addition, the plate may be removably mounted to an articulator and adjusted with respect to these axes based upon three linear and three angular measurements related to the positioning of a patient's maxillary dental arch in the patient's skull.

La présente invention se rapporte de manière générale à un appareil et un procédé destinés à positionner un modèle d'arcade dentaire maxillaire (13) dans un articulateur dentaire dans le but de simuler le positionnement d'une arcade dentaire maxillaire représentée par le modèle d'arcade. On peut positionner ledit modèle d'arcade sur une plaque (14) ayant une surface sensiblement plane dotée d'un point d'articulation (20) à travers lequel sont alignés trois axes, généralement perpendiculaires les uns par rapport aux autres. Il est en outre possible de fixer la plaque, de manière détachable, à un articulateur et de l'ajuster par rapport auxdits axes en fonction de trois mesures linéaires et de trois mesures angulaires associées au positionnement de l'arcade dentaire maxillaire d'un patient au sein du crâne dudit patient.
