Hypothesis
Posts and cores made from modern, digital methods should perform equally as good regarding fit as conventionally made PCs.
Conclusion
The study suggests that posts and cores fabricated with the SLM technique, based on digital impressions, may offer a superior internal fit compared to conventionally cast counterparts using VPS impressions.
Supporting Evidence
- The digital impression technique showed promise for achieving superior internal fit.
- Significant differences were observed at specific measuring points.
- Both methods exhibited variability in fit measurements.
Takeaway
This study looked at how well dental posts fit when made using digital methods versus traditional methods, finding that digital methods might fit better.
Methodology
The study used a typodont tooth model to create impressions with digital and conventional techniques, then measured the internal fit of the resulting posts and cores.
Potential Biases
Operator skill and experience can significantly influence the accuracy of digital impressions.
Limitations
The evaluation of internal fit was limited to specific measuring points, and other factors such as occlusal forces and clinical performance were not assessed.
