What Is PMMA Dental

PMMA dental blank is a durable and stable PMMA (polymethyl methacrylate) milling block for temporary restorations. It has low water absorption and solubility, providing high long-term stability and homogeneity. PMMA block contains no toxic or allergic substances, can be used in the mouth for a long time, is easy to grind and polish, and can be painted or layered for maximum beauty. The temporary restoration process is designed by CAD process with intraoral or impression data and then produced by the milling system.

Polymethylmethacrylate (PMMA) is commonly used in dental restorative applications. Mainly reflected in the manufacture of artificial teeth, orthodontic retainers, temporary crowns, and denture bases. But not limited to this scope of application. PMMA possesses the unique properties of low density, aesthetics, and easy handling, with customizable physical and mechanical properties, making it a suitable and popular biomaterial for dental applications.

Performance of PMMA:

• Thermal performance

• water absorption

• Solubility

• Impact strength

• Bending strength

The first use of polymethyl methacrylate (PMMA) as a dental device was for the fabrication of complete denture bases. Its qualities of biocompatibility, reliability, relative ease of manipulation, and low toxicity were soon seized upon and incorporated by many different medical specialties.
