The search for dental restorative materials that seamlessly blend strength, safety, and aesthetic appeal has long been a priority in dentistry. Mathym®’s innovative nano-zirconia suspension with high refractive index, zilight®, is at the forefront of addressing this challenge.
Meeting the Demand for Aesthetic and Strong Dental Materials
Patien
ts are looking for dental restorations that are not only durable but also visually natural. Traditional materials like porcelain-fused-to-metal often fall short, especially in visible areas like the front teeth due to their opacity and sometimes greyish hue. While all-ceramic restorations offer some improvements, they still face some issues such as chipping, brittleness, and in particular limited translucency.
Yttria-Stabilized Zirconia (YSZ) ceramics, particularly those doped with 3 mol.% yttria (3YSZ), have gained popularity for their high strength, biocompatibility, and compatibility with CAD-CAM technologies. However, conventional 3YSZ often lacks the translucency required for highly aesthetic dental restorations.
Achieving Superior Optical and Mechanical Properties with zilight® range
The control of Mathym’s zirconia grain size to less than 100 nm enables to produce high translucency ceramics without compromising solidity. Moreover, the adjustment of yttria doping in the 8 mol.% range also allows enhanced optical transparency. The obtained ceramics exhibit opalescence similar to natural enamel, creating a bluish and orange appearance under different lighting conditions.
These properties linked to the miniaturization of residual pores, the refinement of grain size, proper doping concentration, and sintering ability at only 900°C make zilight® a superior alternative to existing commercial options for dental applications.
The low sintering temperature is a remarkable competitive benefit that also allows energy consumption reduction, short processing times, and can minimize potential thermal damage to other components.
Compatible with ceramic 3D printing, our innovative solution is designed to meet advanced restoration techniques needs.
Enhancing Dental Applications with Mathym’s Innovations
Mathym’s commitment to innovation extends beyond zilight® nano-zirconia suspension.
Our offering also includes advanced dental nanofillers such as ytterbium fluoride, filixio®, and cerium nanoparticles, designed to enhance or add specific properties to dental materials such as radiopacity, wear resistance and color stability.
Aditionally, the nanoparticle functionalization ensures compatibility with various dental monomers, even at high concentrations.
All these advancements bring superior results across a variety of restorative procedures while preventing secondary caries by inhibiting bacterial growth and promoting enamel remineralization.
