Dentsply Sirona IRM (Intermediate Restorative Material) is a self-curing polymer-reinforced zinc oxide eugenol restorative engineered for reliable intermediate and long-term temporary restorations and cavity base applications. The polymer reinforcement significantly enhances the mechanical properties of the conventional ZOE formula, delivering high dimensional stability, low solubility, and superior abrasion resistance for durable temporary restorations that maintain their integrity under functional loading. The hand-mix powder and liquid system provides straightforward preparation and easy chairside application.

Key Features:

• Polymer-Reinforced ZOE Formula: The polymer enhancement elevates the mechanical performance of the conventional zinc oxide eugenol base, delivering superior dimensional stability, high abrasion resistance, and reduced solubility compared to unmodified ZOE materials for more durable intermediate restorations.
• Self-Cure Chemistry: Chemical polymerization requires no curing light, ensuring thorough and consistent setting regardless of cavity depth, geometry, or access limitations — suitable for a broad range of temporary restoration and base material applications.
• Dual Indication — Temporary Filling & Base: Suitable for use as both a standalone intermediate temporary restoration and as a protective base or liner beneath permanent restorative materials, providing versatility across a range of restorative treatment planning scenarios.
• Low Solubility & High Dimensional Stability: The formulation resists dissolution and dimensional change in the oral environment, ensuring the restoration maintains its marginal seal and structural integrity throughout the intermediate restorative phase.
• Powder & Liquid Hand-Mix System: The 38g powder and 14 mL liquid dispensing format allows for straightforward chairside preparation with adjustable consistency, supporting both base and temporary filling applications with a single versatile material.
