Making the framework try-in, altered-cast impression, and occlusal registration in one appointment

This article describes an altered cast impression procedure that uses the prefabricated impression trays and record base for obtaining the jaw relation record. This method allows the framework try-in, altered cast impression, and jaw relation record to be efficiently completed in a single appointment.
