How is the impression tray prepared for an elastomeric impression?

The correct method for preparing an impression tray for an elastomeric impression involves coating it with adhesive. This step is essential because the adhesive enhances the bond between the tray and the impression material. Elastomeric impression materials are designed to capture precise details, and using adhesive ensures that the material adheres properly to the tray, preventing separation during the impression-taking process. This helps achieve accurate and reliable impressions, which are crucial for the creation of dental prosthetics and restorations.

Rinsing the tray with water is not advantageous as it may introduce moisture into the impression-taking process, which can interfere with the setting of the impression material. Sanding the tray for texture is unnecessary and might damage or alter the tray's surface, negatively affecting the quality of the impression. Heating the tray for flexibility is not a common practice, as elastomeric materials do not require heat to function effectively. Therefore, applying adhesive is the best practice to ensure a successful impression.
