IRM restorative is a specially formulated dental material designed for intermediate restorations with a limited lifespan of up to one year. It is composed of a combination of zinc oxide and eugenol, which work together to provide temporary dental restorations. The material is reinforced with polymers to enhance its strength and durability, ensuring reliable performance during the designated period. One of the key applications of IRM restorative is as an intermediate direct restorative filling material. It can be used by dental professionals to restore damaged teeth temporarily, providing functional and aesthetic benefits until a more permanent solution is implemented. Additionally, IRM restorative can serve as a base material under non-resin-containing permanent restorations. This means it provides a stable foundation for restorative materials and cements that do not contain resin components. It should not be used in patients who have a known hypersensitivity or severe allergic reaction to eugenol or any of the other components present in the material. Furthermore, direct pulp-capping, which involves placing the restorative material directly onto exposed dental pulp, should not be performed with IRM restorative. Additionally, it should not be used as a base under resin-containing adhesives, restoratives, or cements. IRM restorative is available in two convenient delivery forms. The powder/liquid version allows for easy hand mixing, providing flexibility and control during preparation.

INDICATIONS:

• It is an intermediate restorative material. In a clinical study, it was compared to other ZOE (Zinc Oxide- Eugenol) compositions and an EBA (Eugenol and o-ethoxy benzoic acid) formulation. Result: it was judged superior for both Class I and II restorations ( at one and two-year observations).
• Among the many applications are the restoration of deciduous teeth (when permanent teeth are two years or less from eruption); restorative emergencies; caries management programs; dental school clinics and public health dental programs.
• It is used as a base under cements and restorative materials that do not contain resin components, such as amalgams, and inlays and Onlays.

CONTRAINDICATIONS:

• Patients who have a known hypersensitivity or severe allergic reaction to eugenol, or any other components.
• Direct pulp capping
• Base under resin-containing adhesives, restoratives or cements.

ADVANTAGES:

• The eugenol content in the polymer-reinforced zinc oxide-eugenol composition gives the material sedative-like qualities on hypersensitive tooth pulp and is a good thermal insulator as well.
• Other physical-related clinical advantages include excellent abrasion resistance, good sealing properties and low solubility.
