Impression Compound Tracing Sticks is a Type 1 low fusing material primarily used for border extensions on impression trays. 17.3 Impression compound. 2. Advocated by Jones – not used due to the heat of polymerization and monomer irritant. Impression compound sticks can also be used to modify a dentate tray by building up material where teeth have been extracted. primary impression with impression compound in a nonperforated stock tray; the borders are refined. Border molding is done with low fusing compound. low fusing compound for border molding. The high viscosity also makes it ideal when recording the full depth of the sulcus. Final impression is made either using zinc oxide eugenol or with a medium viscosity elastomer. This is done by squirting ice water from a bulb syringe along the borders of the completed impression and over as much of the impression surface as possible. 29 Impression Compound is a thermoplastic impression material available in cakes – for full or partial impressions – and sticks – for copper band impressions and for adding to the periphery of an impression tray. In the first technique, the primary impression is made with low-fusing modelling compound (Kerr white cake compound). impression wax is often used in … 3) Modeling compound. Above 45°C and Type 2 which is high fusing with a fusion temperature of approximately above 70°C. Each coloured variant has a controlled working temperature. When the impression is acceptable, the low-fusing wax must be hardened in the mouth.
