Whip Mix MainStay Disposable Articulator Pin Quadrant System – 50 Sets (MPN 8252)

The Whip Mix MainStay Disposable Articulator Pin Quadrant System is offered in sets of 50 and is designed to eliminate the need for model formers or a gypsum base, accommodating any occlusal relationship and gypsums of all expansion ratios. The flat-table base features no external walls or raised edges, allowing unobstructed seating and removal of dies and model segments. Each numbered base includes a raised anti-rotational spine for die stability without drilling, and built-in support rods provide a vertical stop suitable for edentulous models. The durable hinges resist breakage and can be heated to achieve a custom occlusal relationship.
