Dental impression spacer

A dental impression spacer is a thin, single-use device made of wax or plastic that is placed on the gums and dental structures before taking a preliminary impression. It creates a consistent gap between the oral tissues and the impression tray, allowing excess material and air to escape and improving the accuracy and ease of the final impression process.

These devices are intended for one-time use only and are discarded after the preliminary model is made. As single-use devices, they are typically regulated as low-risk products and supplied sterile or non-sterile for immediate clinical use without reuse.
