Verification of extraoral versus intraoral scanning techniques: fit accuracy implications for 3D printed and milled zirconia crowns (An in-vitro study)

Key Points

• Fit accuracy for zirconia crowns differed based on scanning technique used, with extraoral scans showing superior results.
• Data showed a significant variance in fit accuracy measures, where the extraoral method achieved 92% fit accuracy compared to 84% for intraoral scans.
• In-vitro analysis employed advanced scanning protocols to evaluate both extraoral and intraoral techniques for dental restoration fabrication.
• Findings advocate for the use of extraoral scanning in clinical settings for improved crown fit, potentially boosting long-term restoration success.
