An instrument on which dental study models are mounted or attached, which simulates the hinge movements or actions of the jaw. There are two types of articulators: 1) The more sophisticated and complex anatomical articulator 2) The simpler functional articulator When doing this double-jaw surgery, the anatomical articulator is used. One function of the articulator is in doing model surgery, which is a three-dimensional aid in surgical planning.
An Articulator is a mechanical device used in dentistry to which casts of the maxillary (upper) and mandibular (lower) teeth are fixed and reproduces recorded positions of the mandible in relation to the maxilla. An articulator assists in the fabrication of removable prosthodontic appliances (dentures), fixed prosthodontic restorations (crowns, bridges, inlays and onlays)and orthodontic appliances.
