Dentsply Intermediate Restorative Material IRM 05/2024

Dentsply Intermediate Restorative Material, IRM Polymer-reinforced zinc oxide-eugenol restorative cement  Expiration 05/13/2024 IRM is a zinc oxide-eugenol intermediate restorative cement, that is polymer enhanced for temporary filling or as a base. This material exhibits high dimensional stability, low solubility and is particularly abrasion-resistant. IRM Intermediate Restorative material is designed for intermediate restorations intended to remain in place for up to one year. Among the many other applications are emergency placement prior to complete treatment, endo access openings, pedo teeth that will soon exfoliate, and caries management programs. Its strength properties approach those of zinc phosphate cement. This material is available in an ivory shade via capsule or a powder liquid hand-mix delivery.  INDICATION: 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-ethoxybenzoic 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 restoration of deciduous teeth (when permanent teeth are two years or less from eruption); restorative emergencies; caries management program; 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.   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.
