dental material combination axioms #24

direct dental material placement process
dental material attachment process

Each should be part of a tooth restoration
The two should also realize target of material addition and material to be 
added roles, and have specified outputs that are restored tooth.(unless pontics 
can also be restored, in which either restored or pontic)
Also have specified inputs that are tooth or restored tooth, or, if pontics can 
be restored, then function tooth. (currently only tooth is specified input, but 
you can further restore an already restored tooth so restored tooth needs to be 
included, at least)

Do I understand correctly that dental material fusion process happens outside 
the mouth?
Dental material fusions should have at least 2 dental materials as specified 
inputs, and (if I understand correctly) dental material as output.

That is correct. You  cannot bake porcelain onto metal in a living creature's 
head.

 It sounds true, but circular.  A porcelain-fused-to-metal crown  could be considered to have the "dental material" "porcelain-fused-to-metal".  But, that is an odd way of thinking.  when I think of dental materials, I think of  macroscopically  homogeneously-looking stuff.

material in the sense of OGMS does not imply macroscopically homogeneous. If 
that's a useful distinction for the ontology then we need to define it as a 
subclass. We should check that that's the sense that used in all cases where we 
use dental material in the ontology.

-> in the sense of "BFO"

We don't need to make that distinction for the purposes of our project, nor 
have I seen a research paper focusing on it.  so, let's leave it out.
