Articulators are classified into arbitrary positional and functional by Boucher.
Arbitrary positional articulators hold the mandible in a pre-determined, fixed position that does not necessarily represent the patient's true centric relation or functional movements.
Functional articulators, on the other hand, aim to simulate the patient's individual centric relation and dynamic movements of the mandible, allowing for a more accurate representation of the patient's actual occlusion. Boucher's classification system is based on the type of articulation and the way it records and transfers the patient's jaw movements to the dental casts.
