In a dental articulator having articulator arms which extend forwards in their working position, of which one is mounted in two swivel/sliding joints to pivot about a swivel axis extending at right angles to the vertical longitudinal centre plane, said joints being arranged on both sides of the vertical longitudinal centre plane as mirror-images and being each formed by an articular recess in an articular housing and a spherical head that engages through an opening in the articular recess, and the articular recess has a sagittal guide surface, a Bennett guide surface and a lateral guide surface, and associated with each swivel/sliding joint is a locking device with a locking element for locking the associated swivel/sliding joint in its 0-position (final biting position), and the locking element can be adjusted between a locking position and a releasing position allowing sliding movements in the associated swivel/sliding joint, a form-locking connection is provided between the locking element and the spherical head for an attachment between the lower part and the upper part that is effective in the longitudinal direction of the swivel axis.
