Overview

In vitro study evaluates how pulp chamber design and scanner type affects scan accuracy for crowns, suggesting implications for better digital fabrication.

Key Points

This study aims to assess how different pulp chamber geometries and intraoral scanners impact the accuracy of digital scans for 1-piece endodontic crowns.
Four experimental models with varying pulp chamber depths and axial wall configurations were created.
Each model was scanned multiple times using two different intraoral scanners, yielding a total of 88 scans.
Scan accuracy was evaluated by comparing to reference scans using 3D analysis with RMS measurements.
Significant differences in scan trueness were found based on pulp chamber geometry and scanner type (P<.001).
The iTero scanner produced lower RMS values for axial wall configurations compared to TRIOS (15.7 ±1.3 µm vs 34.3 ±3.7 µm).
Statistically significant effects of pulp chamber geometry on scan precision were demonstrated (F=3.47, P=.020).
