    While in Dental school, many pleasant hours were spent waxing and
    casting fantasy projects. There are so many dental alloys, and they
    are much more expensive than the typical jeweler's casting grains 
that
    I do not see any sense in using these. If you are talking about using
    old crowns for casting metal: it works but you would have to do a
    Karat analysis of the alloy to know how to label it. To get good
    castings you would also have to add virgin metal to the melt. I do 
not
    think this makes economic sense. 

    Now to the dental investments: they are designed to work as a system
    with the matching plaster, rubber and wax materials to end up with a
    casting that accurately fits a prepared tooth. Again much more
    expensive, more accurate than you need.
