ABSTRACT:
Dental articulators have conventionally been constructed so as to utilize a lower assembly including a mandibular bow and an upper assembly including a maxillary bow connected together through the use of simulated condyles and fossa in such a manner as to permit movement between the two bows simulating the movement of the maxillary teeth relative to the mandibular teeth. The utility of such articulators can be improved through the use of a latch structure connecting the upper and lower assemblies in such a manner as to permit such movement and in such a manner as to permit the upper assembly to be moved into stable positions in which the maxillary bow extends substantially vertically from the mandibular bow and in which the maxillary bow and the mandibular bow both face upwardly.
