Dental Materials, Impression, Compound
Definition : Dental impression materials with thermoplastic properties (known as compounds) designed to make an accurate negative reproduction of a given area of the oral cavity. These dental impression materials may consist of dedicated synthetic resin or a wax-like mixture of stearic acid, resins, and oils mixed with an inner filler (e.g., talc) and a pigment. Compound dental impression materials are supplied as cakes, wafers, or sticks and in various colors to aid in distinguishing between products of different softening temperature ranges. These dental impression materials allow easy corrections and additions; their viscosity is controlled with temperature. They are used in dental offices for preliminary full denture and edentulous impressions, for support of edentulous areas or saddle areas, and to facilitate either preliminary or final impressions for partial dentures or better study models. Dedicated compound materials based on wax or synthetic resins are available.
