A method is disclosed for forming an accurate stone cast from an
impression of a body region, used for the purpose of prosthetic
fabrication, such as dental crowns and artificial eyes and hearing aids.
The initial step of this unique method is to affix a relatively thin mix
of wet dental stone in contact with the internal surface of the
impression. After this initial layering has cured, a subsequent pour is
made to sufficiently fill the impression to form a cast.
