Bleach Shade dental PMMA disc CAD CAM dental pmma blank
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
Material: Made of high-quality polymethyl methacrylate (PMMA), it boasts excellent biocompatibility and complies with relevant biosafety standards. It has passed ISO 10993 biocompatibility testing, ensuring it is non-irritating and non-toxic to oral tissues.
Specifications: Available in a variety of diameters and thicknesses, including 71mm, 95mm, and 98mm, and thicknesses ranging from 10-25mm, to meet diverse restoration needs.
Product Features and Benefits
Aesthetics
Excellent Color Match: Available in a variety of colors, including Bleach Shade, to better match the patient's natural tooth color. Especially for those seeking teeth whitening, Bleach Shade offers a more natural, brighter appearance. The product color complies with the VITA colorimetric standard, accurately matching 16 VITA shades and bleach shades, ensuring the restoration matches the color of the surrounding teeth. Natural Transparency: Some products feature a multi-layered structure, such as the DIGILUX PMMA Disc MONO, which boasts 16 color gradients, transitioning from high transparency at the incisal edge to a darker hue at the cervical region. This simulates the optical properties of natural teeth, giving the restoration a more natural and realistic appearance.
Mechanical Properties
High Strength: CAD/CAM dental PMMA blanks offer high flexural strength, with some exceeding 120 MPa. Compared to traditional materials, they can withstand chewing pressure and are less prone to breakage, making them suitable for long-term temporary restorations or bridges with large spans.
Excellent Wear Resistance: PMMA undergoes special treatment for excellent wear resistance, ensuring that the restoration maintains its form and function over long-term use, reducing wear and deformation.
Processability
Easy Milling: Suitable for CAD/CAM processing, it can be precisely machined using a five-axis milling machine, enabling access to complex undercuts and meeting the design requirements of various restorations. The product offers excellent milling performance, is less prone to cracking or chipping, and offers high processing efficiency. Excellent Polishability: The finished restoration surface is easy to polish to a high gloss, which is not only aesthetically pleasing but also reduces food residue and bacterial adhesion, promoting oral hygiene.
Stability
High Color Stability: The restoration is less likely to change color over long-term use, maintaining its aesthetic appearance. This is due to the material's use of high-quality pigments and a stable formula, which has undergone rigorous aging testing.
Excellent Dimensional Stability: The product exhibits minimal dimensional change during processing and use, ensuring a precise fit between the restoration and the tooth, enhancing the reliability of the restoration. This is due to its low water absorption and high density, achieved through manufacturing under high temperature and pressure.
