Source: G.E. White: Osseointegrated Dental
Technology (QZ)
FORMULA: net wax weight x density of the alloy = the amount (g.) of casting alloy to use
1.05
Otherwise as the melt solidifies, the cross sprue
shrinks, which causes distortion to the construction.
The sprues should not have any contact with
another after casting (no casting button) in order
to avoid distortion of the framework.

5.2 Deduct the weight of all metal parts /
