Hypothesis
There would be no difference in the HU measured by the four types of implant planning software after MDCT and CBCT imaging.
Conclusion
HU values can be accurately measured using MDCT with any implant planning software, but not with CBCT.
Supporting Evidence
- The HU values measured using MDCT were not significantly different from the standard values.
- Significant differences were found in HU values measured after CBCT imaging.
- HU values from CBCT cannot reliably assess bone quality.
Takeaway
This study found that while some software can measure bone density accurately using MDCT, they can't do the same with CBCT, which is less reliable.
Methodology
The study used MDCT and CBCT imaging on three specimens to compare HU values measured by four different implant planning software programs.
Limitations
The study was limited by the number of imaging devices and specifications available.
