PMMA (Polymethyl Methacrylate) is a type of acrylic resin widely used in dentistry for fabricating temporary restorations, denture bases, and CAD/CAM dental prosthetics.
It is a thermoplastic polymer formed through the polymerization of MMA (methyl methacrylate) monomers. Due to its combination of esthetics, biocompatibility, ease of processing, and cost-effectiveness, PMMA has become one of the most commonly used dental polymers.
Digital denture solutions
Revolutionize Digital Denture Workflow.
Hairey multi-color resin adopts a unique layered design, which can not only be used for the production of temporary crowns and bridges, but also can be used to carve and make full dentitions, thus helping you realize the production of digital full dentures.
Material integrity
Why Hairey PMMA Outperforms the Rest?
Look closer. The microstructure tells the story.
While other brands cut corners with low-grade industrial materials—risking patient toxicity and structural failure—Hairey sets a new standard. Our high-purity raw materials create a dense, stain-resistant shield that looks natural and stays strong.
