Hypothesis
How do different preparation designs affect the trueness and internal fit of 3D printed provisional veneers?
Conclusion
The butt joint preparation showed the best trueness among the three types of veneer preparations studied.
Supporting Evidence
- The butt joint preparation had the best trueness out of the three groups.
- There was no significant difference between the butt joint and feather edge groups.
- The palatal chamfer group showed increased deviation compared to the others.
- A post-hoc power analysis indicated that the sample size was sufficient to detect effects.
Takeaway
This study looked at how well different types of 3D printed veneers fit on teeth, finding that one type fits better than the others.
Methodology
The study involved scanning 60 dental preparations with different designs and comparing the fit of 3D printed veneers using metrology software.
Limitations
The study was limited to in vitro conditions and may not fully represent clinical outcomes.
