Hypothesis
The null hypothesis was that there would be no differences in the surface roughness values of the four different scan bodies after repeated sterilizations.
Conclusion
Autoclave sterilization minimally affects the chemical properties of both PEEK and titanium scan bodies, but PEEK's surface roughness changes with repeated heating cycles.
Supporting Evidence
- FTIR spectra showed significant changes in surface properties after sterilization.
- XPS analysis indicated minimal degradation in PEEK and titanium scan bodies.
- Surface roughness of PEEK scan bodies changed significantly after repeated sterilization cycles.
Takeaway
This study looked at how repeated sterilization affects dental implant parts. It found that while the chemical makeup stays mostly the same, the surface texture of some parts can change after being heated a lot.
Methodology
The study used Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and optical profilometry to analyze the scan bodies before and after three autoclave sterilization cycles.
Limitations
The study used a single-scan body for each design and did not assess the effects of multiple sterilization cycles on bulk properties.
