As well known, the fusion process of dental alloys in the laboratory consists of putting the
solid metal in a
furnace at controlled temperature, or using the system of crucible
with oxygen and propane.
The metal,
made liquid that way, gets immediately
put in a previously heated fireproof
cylinder. On getting cold
the alloy get its solid state
again, reproducing the fixed shape. During the phase ransition
(solid -> liquid -> solid) the metal undergoes
stability variations, then the
(solid) object is
treated by a thermal procedure, that is said by experience to be
able to guarantee stability. This
procedure is generally followed with all kinds of prosthesis with noble or palladinized alloys. After
the polishing treatment to make it
fit the alloys for ceramics undergo a further thermal treatment to
produce a chemical bond with ceramics.

As well known, the metal treated that way provokes oxidationreduction
pheno mena in the buccal cavity
that weaken the harmlessness of the object. After variousresearches and experiences about the phases of metal manufacturing in 1992 I begun to stabilize alloys by the help of a gelatinoid compound I have
created, which cuts down
surface oxides heavily, and above all
prevents them from forming again in the
following bakings. |
Rosario Muto was
born on the 6/9/58 in Naples and got
a diploma in 1979 at Istituto professionale
"Casanova"in Naples He has been
in charge of a dental
technology laboratory since 1981. At pres- ent he works in
Prato (PO) and
collaborate
with Odontologist
Dr.Marco Cipriani. He has taken part in
several advanced refresher courses as to gnathology,
prosthesis implant and metallurgy. He has
attended ceramics- metal master courses
in Italy and abroad, cooperating with several firms about electro
medical system projects and realization. |
