promising and provides a basis for exciting
improvements in dental implant design for
patients with compromised bone healing.
However, the body of research to date
has still not clearly identified the optimal
pore size, geometry and graduation for
the most effective biomechanical and
biological properties. Therefore, further
studies are necessary to evaluate the
potential of advanced manufacturing
methods to optimize the porous titanium
structure of dental implants. •

of the existing standards in IATA, DOT,
OSHA, EPA and NFPA for determining
flammability and combustibility of
titanium are acceptable and might
truly reflect what the industry is now
producing and how it is being processed.
“If that is the result, then the ITA Safety
Committee can take the position that
we recognize there have been a lot of
changes in the past 50 years; that the
community has assessed to the best of
its ability that industry is on the proper
course, and the resulting information
will be provided to the ITA membership,”
Lee said. “Conversely, Phase 1 may result
in finding that some testing standards
are incorrect, incomplete or obsolete
and there may need to be a fundamental
examination of what those should be.
After the data and practices are collected
and before any final decisions are
made, ITA will organize a committee of
experts including experts from outside
the industry to conduct an appropriate
peer review to increase the potential for
getting it right.”
This initiative is a continuation of
the Safety Committee’s efforts to bring
awareness to all safety issues when
handling and working with titanium.

Conclusions
In conclusion, our present investigation
demonstrates that special processing of
titanium middle ear implants leads to
increased actin expression and increased
coverage by fibroblasts. The cell growth
on the prosthesis is a main indicator of
its biocompatibility. Furthermore, cell
growth supports the stable integration
of the implant within the reconstructed
ossicular chain. The effects observed in
the present study suggest that this type
of surface modification may be beneficial
for integration in titanium middle ear
prostheses. For reconstructive middle ear
surgery accordingly processed titanium
implants should be preferred. •
