Evaluating point cloud density, surface topography, and accuracy across six extraoral scanners: A correlational and 3-dimensional (3D) comparative study
Key Points
Accuracy varied significantly among the six extraoral scanners tested, influencing clinical applications.
The maximum accuracy observed was 0.1 mm, indicating some scanners perform better than others.
Observational analysis across six different extraoral scanners highlighted their varying point cloud density and surface topography.
Findings may enable improved selection of scanners for dental imaging, though further validation is needed.
