Dentsply Intermediate Restorative Material (IRM) Polymer-reinforced zinc oxide-eugenol restorative cement

FEATURES

• 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.

DESCRIPTION

• 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.
