Whip Mix, Louisville, Ky, has introduced its MainStay™ Disposable Articulator System. The system does not require model formers or a gypsum base, and adjusts to accommodate any occlusal relationship. Its base was designed without external walls or raised edges to prevent interference with the seating of dies and model segments. This feature also means that it can be used with gypsums of all expansion ratios.
Pin models are available in full-arch, anterior, and quadrant sizes. A pinless model comes only in the quadrant size.
