Abstract: This invention relates to an articulator for checking or deciding the biting state of dentures in the mouth by associating upper and lower jaw arciforms for mounting a gypsum model to fabricate the dentures and arbitrarily producing a relative positional relationship between the upper and the lower jaw arciforms. A condyle sphere formed on the lower jaw arciform is supported by a condyle path plate formed at the upper jaw arciform. The condyle path plate is composed of side, upper and lower walls, and can be used as an archon box type or an archon slot type by the operation of the condyle path plate.
