Keystone Industries

Keystone Industries stands out as one of the oldest continuously operating U.S.-based manufacturers focused primarily on high-quality dental materials/devices with additional reach into cosmetic/veterinary health sectors. The firm leverages advanced R&D capabilities—including expertise with UV-cured gel technologies—and maintains robust regulatory compliance across its global operations. With an estimated $93M+ annual revenue and hundreds of employees worldwide, it remains privately owned without public stock listing or recent acquisition activity. Its core business centers around commercialized device/material sales rather than drug development pipelines or therapeutic platforms.
