2. ๏ฝ Dental implants are ideal solutions to missing teeth.
๏ฝ Methods of manufacturing of titanium are alloys preparation,
electrochemical measurements, cell experiments.
๏ฝ Applications of titanium are its used in braces, wires,
implantations etc.
๏ฝ Titanium is an excellent option for dental surgery because of
its ability to be accepted by the body and low risk of
unpleasant allergic reactions.
๏ฝ This makes it for safer surgeries, less painful recovery time for
patients.
3. ๏ฝ Titanium can be found in different
combinations for use in Dentistry.
๏ฝ Pure titanium is composed by 99.5 % of
titanium and 0.5 % of interstitial
elements (carbon, oxygen, nitrogen,
hydrogen and iron) and the proportion of
these elements directly affects the metal
properties.
๏ฝ The screw is usually made of titanium or
other biocompatible materials.
๏ฝ It is a light and strong metal, easy to
manufacture and with low density (40 %
of the iron density).

5. ๏ฝ The microstructure of Tiโ alloys was
examined using an optical microscope
๏ฝ After being polished and etched via a
standard metallographic procedure. The
etching solution is a mixture of HF,
HNO3 and H2O (5%:15%:80% in
volume).
๏ฝ An X-ray diffractometer with radiation
was employed to identify the phase
constitution of the experimental Ti alloys.
๏ฝ The strip specimens Tiโ2X alloys were
prepared for uniaxial tensile test, with
pure Ti as control.
6. ๏ฝ Titanium was immersed in the solution of hydrofluoric acid or
nitric acid. A rough surface was prepared by hydrofluoric acid
etching with posterior Passivating using a combination of
hydrofluoric and nitric acid.
๏ฝ The chemical composition of the titanium was assessed using
a flame and combustion atomic absorption system capable of
determining the quantitative chemical composition of the
interstitial elements contained in the titanium โ including
hydrogen โ with a sensitivity in the parts per million (ppm)
ranges.
7. ๏ฝ The HF and nitric acid causes roughness at the spots where the
titanium was present.
๏ฝ Titanium implant surface chemical composition determined by
photoelectron spectroscopy (XPS).
8. ๏ฝ Titanium is relatively inert, corrosion
resistance in dental implant because of its
thin (approximately 4nm), surface oxide
layer.
๏ฝ Titanium readily absorbs protein from
biological fluids.
๏ฝ Ti surfaces also can support cell growth
๏ฝ Sometimes allergic reactions also shown
when titanium implant in body
9. ๏ฝ UNIVERSAL TESTING METHOD:
There are many
types of testing machines. The most common are universal
testing machines, which test materials in tension, compression or
bending. There are two classes of testing machines,
electromechanical and hydraulic.
10. ๏ฝ The strip specimens of Ti alloys were prepared for uniaxial
tensile test, with pure Ti as control.
๏ฝ The tensile test was performed with an initial strain rate of
5ร10โ1 on a universal testing machine at room temperature.
๏ฝ Load of 200 g for 15 s, repeating eight times in different
positions for each alloy.
11.
12. ๏ฝ Titanium braces strong and lighter-weight, its
biocompatibility property wonโt cause allergic
reactions not cause uncomfortable side-effects.
๏ฝ Titanium is an excellent option for dental surgery
because of its ability to be accepted by the body.
13. ๏ฝ Titanium is an attractive material for dental and biomedical
applications, because of high corrosion resistance, excellent
biocompatibility and high mechanical strength combined with
low density.
๏ฝ Titanium are biocompatible, meaning they will integrate with
human bone and gums.
