A full-arch interocclusal impression tray to eliminate lack of coverage and tendency to distort

This article discusses a metal full-arch interocclusal impression tray. It uses a separation insert that extends into a split handle. Portions of the tray may be used to record sections of an arch singly or in combination from quadrant to full arch. A combination of different materials may be used, selected for low-cost properties that work compatibly side-by-side and/or back-to-back. The tray can be modified by the addition of a mounting stud to the tray handle, which permits linking it to a face-bow to facilitate axis mounting.
