In-vitro study evaluates accuracy of intraoral scanners in dental impressions, suggesting optimized scanning strategies.

The study aims to evaluate the influence of jaw model configurations and examiner experience on the accuracy of intraoral scanners.
Conducted an in-vitro factorial comparative study.
Evaluated different jaw models: upper jaw, upper jaw with palate, lower jaw.
Compared scanning accuracy across seven intraoral scanners.
Data analyzed using a linear mixed-effects model considering model type and examiner experience.
Trueness values varied significantly across scanners, from 29.0 μm to 94.9 μm.
Model type with palate showed a significant positive effect on precision (p < 0.001).
Experience level of the examiner significantly impacted precision (p = 0.04).
All trueness values remained clinically acceptable (< 100 μm).

Buhl et al. (2025) studied this question.
