In any case?  Well, as the article says where you have a number of landmarks, more landmarks that you can compare and also if you have teeth marks as well, then you can make an assessment where you can actually do a positive identification.  This has been done on teeth marks, on a skull photo superimposition, and we have done it ourselves with a case that was presented in Italy three years ago.  But the problem remains that in virtually all other cases, unless you have some quite extraordinary bony abnormality of the skull, which you can match up, then I would have to say that you cannot positively identify.
