Dental impression materials with rigid and inelastic properties, whose main components are zinc oxide and eugenol (ZOE). They are designed to make an accurate negative reproduction of a given area of the oral cavity. These dental impression materials consist of zinc oxide, eugenol, rosin, and a vegetable or mineral oil that acts as a plasticizer and helps to offset the action of the eugenol as an irritant. ZOE dental impression materials are supplied in paste form and are packed in tubes. They are used in dental offices for preliminary compound impressions, mucostatic impressions, corrective washes, rebasing dentures, and denture relines.
