DMG Supertec Trays

Recommended use 1. Block out undercuts on the model with a suitable material, e.g. silicone impression material 2. Mark the tray’s edge with a pencil and make a place-marker out of modeling wax. Note: Exposed gypsum parts should be treated with an alginate insulation. DMG recommends that the gypsum surfaces are irrigated 3. Remove protective cover from the prefabricated tray and adapt the tray to the model 4. Remove excess tray material along the pencil line with a modeling knife 5. Form a tray grip from the excess tray material and attach it to the model. 6. If necessary, smooth material junctions with petroleum jelly 7. Cure the impression tray on the model for approx. 3 minutes with a suitable light unit, e.g. Kulzer® XS* (UVA-VIS blended light/stroboscope). Note: During curing it is possible to apply a light-curing varnish e.g. Dry Coat to the surface of the impression tray so that it is cured at the same time as the tray material. This creates a dry, shiny surface 8. If the impression tray is not treated with light-curing varnish, remove the dispersion layer with alcohol or acetone. If light-curing varnish is used this is not necessary 9. Let the place holder wax boil out 10. Remove the impression tray from the model and cure the underside for approx. 3 minutes with a suitable light source e.g. Kulzer® XS* (UVA-VIS mixed light/ stroboscope). Note: During curing it is possible to apply a light-curing varnish e.g. Dry Coat to the surface of the impression tray so that it is cured at the same time as the tray material. This creates a dry, shiny surface. Note: The impression tray can be subsequently treated with corundum stones or fine carbide-fine cross-cut carbide burs. Wear suitable breathing protection when performing machining.
