What impression material is VPS adhesive used with?

The choice of VPS adhesive is specifically associated with silicone impression materials, particularly vinyl polysiloxane (VPS). VPS is a type of addition-cured silicone that requires an adhesive to enhance its ability to accurately capture detail and prevent separation from the tray during the impression process. This adhesive provides a secure bond between the VPS material and the impression tray, ensuring an accurate and dimensionally stable impression.

When considering the other options, polyether impression materials, while they have their own bonding agents that may be used for adhesion, do not utilize VPS adhesive. Rubber base impression materials, also known as polysulfide materials, have different requirements and properties, making them incompatible with VPS adhesive. Alginate impressions, on the other hand, are water-based and do not require adhesive for bonding to trays in the same manner as VPS does due to their different composition and handling properties. Thus, VPS adhesive is specifically intended for use with silicone impressions, which is correctly reflected in the understanding of impression materials and their corresponding adhesives.
