Abstract: An apparatus for the production of maxillar models through cephalometric analysis with auxiliary graduated occlusal plane by simplifying the construction of maxillar models and its anatomic relation, obtaining greater exactness in the correction of the dentomaxillofacial anomalies and reducing the time of confection of the models. The apparatus is formed of a single base having two towers set with condylar elements that support an upper section that holds the condylar movables. The base and the upper section support both the mandibular and the palatal plates with their platforms. The occlusal plate is placed between these two plates resting over two leading rods. An articulated ruler with a level is used for the transference of cephalometric angles, planes and points.
