ABSTRACT:
The present invention relates to an articulator capable of completely and faithfully reproducing movements of a mandibular cast and maxillary cast. The articulator introduces a suspended mandibular member, the mandible being similar to that of in human beings. The mandible is suspended from the condyles in the glenoid fossa of the tempero mandibular joint. The articulator and the mandibular member are suspended between the maxillary member and the base representing the feet or base in a human. The articulator has a mechanism for anterior incisal guidance by providing incisal pins attached to the mandibular member. The incisal pin attached to the mandibular member creates the anterior guidance on an incisal table resting on the base. The articulator creates the possibility of the condyle executing pure rotary movement in the centric position until a vertical opening between the upper and lower jaws.
