Abstract
A dental articulating system to duplicate a patient's teeth for producing a dental prosthesis includes a pair of trays pivotally coupled together. A plurality of registration pins is disposable in a plurality of registration pin holes formed in at least one of the trays. A thin membrane is disposed across a registration pin hole to close off the registration pin hole and resist dental casting material from substantially filling the registration pin hole. The thin membrane is breakable by a registration pin inserted into the registration pin hole. A method for forming a dental model includes pressing a registration pin through a thin membrane extending across a registration pin hole on at least one of the trays of a dental articulator so that the registration pin breaks the thin membrane and extends through the thin membrane.
