Why to use the „core investing procedure”

When casting CoCr based alloys, the casting contraction is approx. 2.2%. This results in an increased discrepancy between the single fit of the crowns and the total fit of the bridge. Therefore it is recommendable to fill the single crowns with a higher concentration of the investment material than the complete mould

Operating range of the „core investing procedure“

Long span bridges and implant structures Implant retained supra constructions require especially precision castings because of the high precision of the industrially manufactured implant abutments.
