Hypothesis
The study aims to assess and compare the accuracy of post-space impressions captured by three different intraoral scanners using various canal diameters.
Conclusion
Trios3 IOS has the highest accuracy in recording post space impressions, followed by iTero2 and Medit i700 IOS.
Supporting Evidence
- The mean deviation for trueness in post space impression values recorded by the Medit i700 was highest among groups.
- Significant differences were found between the groups for all three IOSs.
- As the diameter of the post space is increased, the accuracy of recording by IOS increases.
Takeaway
This study looked at how well three different digital scanners can take pictures of tooth spaces, finding that one scanner did the best job.
Methodology
Three extracted maxillary central incisors were scanned using three different intraoral scanners, with each tooth scanned 10 times to evaluate accuracy.
Potential Biases
The study was conducted by a single operator, which could introduce bias.
Limitations
The study was in vitro and only used single-rooted maxillary anterior teeth, which may not represent all clinical scenarios.
Participant Demographics
Non-carious natural maxillary central incisors extracted for periodontal reasons.
