Further information

Castdon Resin

 Auto-polymerising, cadmium-free PMMA pouring resin with barbiturate hardener system for the production of total and partial dentures, clinically proven for many years.
 

Characteristics

  • low shrinkage
  • excellent flow characteristics
  • break-resistant
  • colour stable
  • minimum content of residual monomer
  • also suitable for the pressing procedure, relining and repairs
  • successfully tested for biocompatibility

 

  • manufacture wax model as usual
  • functional edges must be free of wax
  • adjust model in flask
  • fix model onto bottom plate by use of wax
  • close flask with brackets
  • check sealing for correct fit
  • shake Siliform before use
  • take 150 ml of each component and mix homogenously by use of spatula
  • fill flask from top in a thin stream
 
  • cure silicone under the same pressure as will be done later with the resin (e. g. Polymax)
  • curing approx. 30 min.
  • remove bottom plate and deflask the model
 
  • pierce two pouring canals into the dorsal area of the jaw ridge
  • one additional canal has to be pierced into the upper jaw, in central position
 
  • remove wax from teeth using the flask bottom plate
  • abrade teeth and apply retention
  • set teeth back into the duplication form
  • no gluing of teeth is necessary due to the moist surface of the silicone
  • application of Castdon Bonding between tooth and basis strengthens connection
 
  • put model into warm water, afterwards dry the surface
  • insulate by use of Isolat film
  • only insulate with one layer!
 
  • set model back into duplication form
  • close flask with bottom plate
  • fill dosing aids (the same filling height guarantees an optimal mixing ratio, 17 g powder/11 ml liquid for one denture)
  • mix Castdon homogenously in a mixing beaker
  • pour it into the flask in a thin stream through only one canal
  • cure inside a polymerisation unit (e. g. Polymax 1) for about 25 min. at a temperature of 45 °C
  • fill with water up to the edge of the flask
  • the resin-filled funnels should not be set under water
 
  • remove the bottom plate after polymerisation
  • deflask the model
 
  • denture can be removed easily from the model
  • further treatments are reduced to: removing of spill-overs, adding of the finishing touches by use of sandpaper
... and polishing – completed!
