I just completed a Maryland bridge for a client/dentist. For #25, an
immediate, with wings from, 23 to 27. The dr asked for it to be
fabricated in non-precious metal. I had to purchase one that matched
the coefficient of thermal expansion, CTE, of the porcelain system I
use. The alloys creator claims, "Medically Pure 99.99+%", Highly
Biocompatible with living tissue", "since 1984 with a 100% success
rate" "We use only VIRGIN metals, straight from the mines that have
been highly refined, electrocized, and vacum roasted (like coffee lol)
to eliminate impurities such as, Arsenic, Lead, Cadmium, Sulfur,
Phosphorous, Iron, Tin, and even Nitrogen. Then they are distilled and
homoginized" "Registered with the F.D.A. under Medical Devices that are
implanted into the body, and manufactured under the F.D.A. and A.D.A
guidelines and have recieved the I.S.O. Certification withe the C.E.
Mark." "insured to protect the lab, Dentist and patient for 5 million
dollars."" If they were not safe the insurance cmpany would not have
insured it"
The bridge came out really nice. Even with repeated firings. I had to
lengthen it bc its an immediate.

OK, doctors, whats your take on Non precious? It seems to be an
affordable alternative to gold.
As biocompatible as 75% AU the company claims.
Thanks! Alex
