Making Temporary Crowns And Bridges Dental Pmma Disk

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.

Making Temporary Crowns And Bridges Dental Pmma Disk specification

Mechanical strength & durability
Handles normal chewing forces during temporary use. The material resists chipping and maintains shape during daily wear. Suitable for restorations with a service period of up to 6 months.

Impact resistance & flexibility
Has a certain level of elasticity, so it is less likely to crack under localized stress. Works well for both single units and multi-unit temporary bridges.

Biocompatibility
Medical-grade PMMA with low residual monomer reduces irritation risk. Suitable for intraoral use over extended periods.

Machining performance
Cuts cleanly in CAD/CAM systems without sticking to tools. The surface after milling is smooth, which shortens polishing time and improves fitting accuracy.

Aesthetics
Available in multiple VITA shades, allowing basic shade matching for temporary restorations. The material shows a natural appearance suitable for anterior and posterior use.
