An articulator device for articulating upper and lower dental casts comprising a base having a generally T-shaped structure defining a tongue-like protrusion including a longitudinal slot. A lower dental cast holding pad is secured to the tongue-like protrusion and is movably disposed along the longitudinal slot for an anterior-posterior direction reposition of the lower dental cast with respect to the upper dental cast for malocclusive correction. A pair of support pins are implanted in the base. A pair of collars are slideably positioned along the support pins and have a pair of thumb bolts for fixedly securing the collars to the support pins. A guide member is slideable along the support pins and is supported by the collars to elevate or lower the guide member in accordance with the movements of the collar. A holder is supported by the guide member and has a generally T-shaped structure defining a tongue-like protrusion. The holder is capable of being laterally moved with respect to the guide member. An upper dental cast holding pad is bound to the tongue-like protrusion of the holder.
