Hypothesis
What is the dimensional accuracy of impressions made using intraoral scanners for post space compared to conventional techniques?
Conclusion
Intraoral scanners show varying accuracy for recording post space, with acceptable results for lengths up to 14 mm.
Supporting Evidence
- All nine evaluated studies reported deviations in accuracy for intraoral scanners compared to conventional techniques.
- The accuracy of intraoral scanners is inversely proportional to the length of post space.
- Shorter post spaces yield better accuracy with intraoral scanners.
- Variations in accuracy are higher in apical regions compared to cervical and middle regions.
- Most studies reported clinically acceptable deviations for post space lengths up to 14 mm.
Takeaway
This study looks at how well digital scanners can take pictures of tooth spaces compared to traditional methods, finding that they work well for shorter spaces.
Methodology
A systematic review of nine studies comparing intraoral scanners to conventional impression techniques.
Potential Biases
All included studies were found to have a risk of bias, with varying levels of concern regarding applicability.
Limitations
The review is limited to in vitro studies and articles published in English after 2000.
