Description:

This is a small articulator that is intended to accommodate sectional casts. It provides a posterior vertical stop and a mechanism for lateral movement, that slightly increases the vertical height of the upper member, presumably to provide for cuspal rise. Contemporary models of this articulator suggest that there has been almost no changes in design for over 100 years. These articulator are made of brass and aluminium.
