How long should mechanical displacement materials remain in place during a dental procedure?

The appropriate duration for keeping mechanical displacement materials in place during a dental procedure is typically between 10 to 15 minutes. This timeframe ensures that the material can effectively achieve the desired displacement of soft tissues, such as the gingiva, without causing unnecessary discomfort or potential damage. By allowing sufficient time for the material to set and work, it helps to create a clear and accurate working area for the dentist, which is crucial for procedures like impressions or crown preparations. This balance helps maintain procedural efficiency while also prioritizing patient comfort and safety.
