Dentsply IRM Temporary Restorative

Dentsply IRM Temporary Restorative is a polymer-reinforced zinc oxide-eugenol composition designed for intermediate restorations intended to remain in place for no longer than one year. It functions as an intermediate direct restorative filling material, providing a reliable interim solution for various dental restorative needs.

This material is formulated as a polymer-reinforced zinc oxide-eugenol (ZOE) composition, ensuring enhanced mechanical performance compared to conventional ZOE materials. It is safe for use within the oral cavity and exhibits biocompatible properties.

Beyond its primary use as a temporary filling, Dentsply IRM can also be utilized as a base material under non-resin-containing permanent restorations. Its versatile applications include the restoration of deciduous teeth, emergency restorations, and integration into caries management programs. The product complies with the specification of ISO 3107 for type II materials.

Cavity preparation
Isolate the field of operation in a preferred manner. A rubber dam is recommended.
Cavity preparation must provide for the mechanical retention of the product.
If caries are present, completely excavate using low-speed and/or hand instrumentation.
Place matrix and wedge where indicated.
Gently dry preparation with a cotton pellet. Avoid desiccation.
Pulp protection
In deep cavities cover the dentin close to the pulp (less than 1 mm) with a hard setting calcium hydroxide liner (Dycal calcium hydroxide liner, see complete Instructions for Use
Dispensing and mixing
Before dispensing, fluff powder (tumble the powder bottle) to assure uniform bulk density of contents. Fill the measuring scoop to excess without packing.
Level scoop with the bottle insert. Dispense two level scoops of powder onto a clean, non-absorbent mixing pad or glass slab. Larger restorations may require additional scoop(s).
Using the dropper cap, dispense three drops of liquid for two level scoops of powder. After dispensing the liquid, replace the original cap immediately to prevent evaporation and subsequent contamination.
Placement
Mixed material may be carried to the preparation with a suitable placement instrument. Adapt, contour, and shape with appropriate instruments. Technique Tip: Dipping the instrument into dry powder left on the pad before using to adapt the material will facilitate placement and minimize sticking.
Use as an intermediate restorative material
Trim excess material. Material may be smoothed by lightly burnishing. The initial set occurs approximately 5 minutes from the start of mixing. Increased temperature, humidity, and powder/liquid ratio may accelerate the setting.
Upon set, remove the matrix band if present. Check and adjust occlusion as needed. Additional carving or occlusal adjustment may be accomplished with a round bur. Avoid gouging material with sharp burs at high speed. Additional polishing is not recommended.
Periodically evaluate the intermediate restoration until the final restoration is indicated. The intermediate restoration should be removed and the final restoration completed within one year of placement.
Use as a protective base
The product is a protective base for non-resin-containing restorative material, such as amalgam or gold.
