summary The aim of this study was to devlop a wax suitable to serve as a function impression material. Several binary mixtures of paraaffin, beeswax and rosin were prepared.They were characterized by differential, thermal analysis(DTA), and tested for plastic deformation, thermal expansion, detail reprouduction and mechanical prperties. It was found that the combinations of paraffin with rosin can funtion well as impression materials, as they combine a high value of plastic deformation at 37°C with relatively low values at room temperature. Concentrations of rosin as small as1% or 2% are adequate to produce this result. The flow of paraffin was significantly reduced by the addition of beeswax.A liner relationship was found between the 37°C flow values of paraffin‐beeswax mixtures and the proportions of the ingredients.
