  • Occlusio-referential articulator
    Patent number: 4573915
    Abstract: It comprises an upper maxillary support (14) and a lower maxillary support (47). The lower support comprises a movable piece (27) on a rack (24) supporting an arm (31) mounted to slide vertically on the movable piece (27) with a limited travel for its vertical displacement on the movable piece (27). The arm (31) carries two intersecting orthogonal slideways (41,42). The upper slideway (42) carries a table (47) mounted on a spherical knuckle. The articulator allows accurate recording and accurate reproduction of the occlusion position of the maxillaries and of the closure of the mandible, without seeking to reproduce the condylar articulations.
