Zonmed PRS-R-01 Permanent Crown Resin is an advanced, high-performance photopolymer engineered for the reliable digital fabrication of long-term permanent single crowns, bridges, inlays, onlays, and veneers. Available in specialized formulations containing 10% or 60% high-quality porcelain filler, this material provides superior mechanical reliability, including excellent pressure, impact, wear, and corrosion resistance.
PRS-R-01 ensures high-precision marginal adaptation, exceptional dimensional stability under masticatory forces, and remains radiopaque and clearly visible on CBCT scans. Designed for both clinical efficiency and superior aesthetics, it features natural translucency and is fully compatible with the Zonmed Polyfix resin stain kit. This allows for a simplified workflow where clinicians can achieve lifelike, high-fidelity shade matches with a quick, intuitive application—eliminating time-consuming mechanical polishing and finishing steps. It is odorless, biocompatible for permanent intraoral use, and maintains high color stability over extended periods of oral exposure.
