How long can an IRM restoration typically last?

IRM, or Intermediate Restorative Material, is designed for use as a temporary restoration in dentistry. It is primarily composed of zinc oxide and provides a good seal to protect the underlying tooth structure. The typical lifespan of an IRM restoration is around several months, which aligns with the role it plays in allowing time for healing or for further treatment planning to occur.

This duration is due to its strength and ability to withstand masticatory forces for a limited time while providing temporary relief and protection from sensitivities. However, it is not intended for long-term use; therefore, while it can effectively serve its purpose for several months, it is expected that a more permanent solution will be sought within that timeframe. This understanding ensures that patients are aware of the temporary nature of IRM restorations and the importance of following up for definitive treatment.
