Whip Mix MainStay Disposable Articulator Pinless Quadrant System – 50 Sets (MPN 8254)

The Whip Mix MainStay Disposable Articulator Pinless Quadrant System is offered in sets of 50 and is designed for use without model formers, a gypsum base, pinning, drilling, or gluing, making it well suited for scanning workflows. The flat base design eliminates external walls and raised edges, preventing interference with die and model segment seating while remaining compatible with gypsums of all expansion ratios. A built-in anti-rotational spine stabilizes dies in place, and numbered bases allow quick reference for die placement. The durable hinges are easy to separate, resist breakage, and can be heated to accommodate custom occlusal relationships. Built-in support rods provide a vertical stop, making the system appropriate for edentulous models as well.
