Gypsum-bonded Investment and Dental Precision Casting (I) Two Investments

open access: yesDental Materials Journal, 2003
The present study compared the TE of two gypsum-bonded dental casting investments, the oldest K and more recent G. They had almost identical composition, 70% refractory (cristobalite) and 30% binder, but had different recommended water/powder ratios, 0.40 (K) and 0.33 (G). The average TE was significantly less (1.19%) in K than in G (1.45%); the volume

Gypsum-bonded Investment and Dental Precision Casting (III) Composition of Investment for the Quick Casting Technique

open access: yesDental Materials Journal, 2004
A simultaneous differential thermal analysis and thermogravimetry method previously established was used to estimate the composition of gypsum-bonded investment marketed for the quick casting technique. Three commercial investments of this type were heated to 700 degrees C at 10 degrees C/min and the hemihydrate content was estimated by the mass ...
