This looks like an interesting technology, but most custom abutments
are not milled by a CAD-CAM technology--they are custom cast, usually
in gold alloy (there is a titanium understructure that screws into the
implant fixture.
They are generally used when the placement of the implant fixture is
such that it is not possible to place a functional, esthetic crown using
a stock (pre-made) abutment. Of course, occasionally fixtures are
placed such that it's impossible to put a crown or attachment in a good
clinical position. That's why collaboration between the surgeon and
restorative dentist is so important.
