3M VPS Tray Adhesive Refill, 17ml

The 3M VPS Tray Adhesive Refill is applied to the inner surface of an impression tray before it is loaded with vinyl polysiloxane, commonly known as VPS, impression material. Its purpose is to ensure a secure, reliable bond between the impression material and the tray itself, so that when the tray is removed from the mouth the impression material stays fully seated in the tray rather than pulling away or distorting, which could otherwise compromise the accuracy of the resulting model.

This step is a routine but important part of taking a high quality impression, since even small amounts of impression material separating from the tray can introduce inaccuracies that affect the fit of a subsequent crown, bridge or other indirect restoration. Supplied in a 17ml bottle as a refill, it is designed to top up practices that already use this adhesive as part of their standard impression-taking protocol.

Dentists and dental assistants apply tray adhesive like this one before most VPS impression procedures. Dental practices across the UAE and GCC that regularly take physical impressions for crown and bridge work keep this adhesive as a routine consumable.
