| Summary: | A new experimental porous glass ceramic coating for dental implants was prepared with
a new formula consisted of a sintered glass ceramic based on alumina, silica glass and boron
trioxide. The resultant sintered objects were anodized by one step anodization method at a constant
potential of 40V and at a temperature of 22°C. X-ray diffraction analysis was performed to
investigate the phase structure of the new material in addition to SEM investigation for surface
texture and pores size and distribution. The new experimental material was subjected to failure
under universal testing machine for compressive strength. The results showed a promising material
to use as coating for implants as X-ray diffraction exhibited an amorphous phase diagram for the
material structure whereas SEM results revealed that the pores in the specimens prepared by
anodization method were highly ordered and the mean average pore size was 6.5-8.5 nm. The
compressive strength test showed that the test-porous glass ceramic coating has a mean numerical
value of up to 7.5 MPa which indicates an ambitious result for the new material. |
