Description
SLEDGEHAMMER is Keystone’s ultra-high-impact Denture Acrylic — the highest impact resistance in the Keystone Denture-Acrylic lineup. Its CROSS-LINKED, color-stable PMMA formulation absorbs impact energy that would shatter standard Acrylic, making it ideal for bruxers, Denture-droppers and patients with a history of fractures. Available in HEAT-CURE (new prostheses) and self-CURE (high-impact repairs, relines and rebases) variants, compatible with most injection systems.
- Highest impact resistance in the Keystone Denture-Acrylic lineup

- CROSS-LINKED, color-stable, cadmium-free PMMA
- HEAT-CURE for new prostheses; self-CURE for high-impact repairs/relines
- 12–14 minute working time; no bleaching, blanching or streaking
