This package contains 25 sets of Anterior Pin Sets for use with the Whip Mix MainStay Disposable Articulator System. The pin-based design eliminates the need for drilling, with a raised anti-rotational spine that prevents die movement and numbered bases for quick reference of die placement. The articulator system requires no model formers or gypsum base and features a flat-table base without external walls or raised edges, allowing unobstructed seating of dies and model segments while accommodating gypsums of all expansion ratios. Built-in support rods provide a vertical stop suitable for edentulous models, and the durable hinges can be heated to achieve a custom occlusal relationship.
