Dental Material Flexible PMMA Acetal Blocks
Zotion dental PMMA blocks are made from highly cross-linked polymethyl methacrylate (PMMA) and can be used for temporary restorations including crowns and bridges. The blocks are available in single-layer, multi-layer and flexible resin options and are compatible with leading CAD/CAM systems such as Wieland, VHF, Roland, Imes-Icore, Zirkonzahn and Amann Girrbach. Diameters are available in 98 mm, 95 mm and AG71 mm and in a variety of colours including A0, A1, B1, Vita 16, Pink and Clear. Used for denture restorations, temporary crowns and sculpted trays as an alternative to dental wax, these PMMA blocks offer numerous benefits. They have excellent biocompatibility, natural tooth colour, superior wear resistance and are manufactured under a high temperature and pressure process to ensure durability. The multi-layer variants offer excellent machinability, stress-free processing to reduce deformation, a high melting point to ensure stability during milling, and anti-static properties for a smooth and efficient workflow. With a hardness of 75-85, a melting point of 240-270°C, a density of 1.19, excellent toughness, good processability, an ash content of 0.029% and a shrinkage of 0.5%, these PMMA blocks ensure precision, durability and efficiency in dental restorative procedures.
- Product Introduction
Products Description
Dental Material Flexible PMMA Acetal Blocks is a dental material that is both flexible and stable, and is often used to make temporary restorations, flexible dentures or functional brackets. Based on traditional PMMA, this product is modified by introducing Acetal (polyoxymethylene), so that the material not only maintains the excellent biocompatibility, low water absorption and easy processing of PMMA, but also has the excellent wear resistance, low friction and good elasticity of Acetal.

Raw materials and their advantages
High-purity PMMA resin
Medical-grade PMMA resin is used, which has low density, good biocompatibility and excellent mechanical properties, providing a solid matrix for the material.
Acetal modified additive
The introduction of high-purity Acetal modified ingredients improves the rigidity of traditional PMMA, giving the product better flexibility and impact resistance, while reducing the friction coefficient and improving wear resistance.
Synergistic coloring system
Advanced coloring technology is used to ensure that the product presents natural and beautiful tones in a transparent or translucent state to meet different repair needs.
Manufacturing process
Raw material premixing and ratio control
Precisely measure high-purity PMMA resin and Acetal modified additives to ensure that the two materials are mixed in the best ratio, which can not only maintain the stability of PMMA but also give full play to the flexibility of Acetal.
Add appropriate amount of colorant and stabilizer to make the product uniform in color and meet clinical aesthetic requirements.
Industrial polymerization and heat curing
Prepolymerization is carried out in an industrial polymerization furnace with strict temperature and pressure control. A programmed water bath or high-temperature heat curing process is used to fully polymerize the mixed materials to form a homogeneous, pore-free blank.
The heat curing process ensures the dimensional stability and mechanical properties of the product, while reducing residual monomers and improving safety.
Block cutting and finishing
The large block blanks after polymerization are cut into standard-sized Acetal Blocks by precision CNC equipment (CAD/CAM system).
Subsequent surface polishing and quality inspection are carried out, and each block has excellent optical transparency, low surface roughness and high mechanical strength.
