Hypothesis
This study sought to compare the sealing capability and marginal fit of two external hexagon implant systems.
Conclusion
Both implant systems showed leakage and gaps at the implant-abutment interface.
Supporting Evidence
- Both groups showed increased leakage over time, particularly at 144 hours.
- SEM analysis revealed gaps in the implant-abutment interface for both systems.
- The study used a spectrophotometer to measure the amount of color marker released as an indicator of leakage.
Takeaway
The study looked at how well two types of dental implants fit together and whether they leak. Both types leaked and had gaps.
Methodology
Two external hexagon implant systems were tested for sealing capability using a color marker and analyzed with SEM for marginal fit.
Limitations
The study only evaluated two types of implant systems and may not represent all external hexagon implants.
