| Popis: | Intraoral scanners (IOS) are essential tools in dental prosthodontics, enabling efficient digitization of dental arches for CAD-CAM workflows. The Primescan IOS (Dentsply Sirona) can be fitted with three scanning sleeves, based on the level of hygiene imposed by the clinical situation and health regulations: a standard sleeve (SS), an autoclavable sleeve (AS), and a disposable sleeve (DS). Most studies evaluating accuracy use local best-fit algorithms to superimpose a reference scan and a test scan, providing relative accuracy. This study proposes an alternative evaluation method based on metrological principles and aims to compare the quality of scans taken with the three types of sleeves. An 8 mm aluminum oxide sphere was scanned 24 times using each sleeve. Mesh analysis was conducted, and measures of trueness, precision, and digitizing noise were calculated. Significant differences in trueness were identified between AS-DS (p < 0.001) as well as AS-SS (p < 0.001), while no significant differences were found between the sleeves for precision (p = 0.623). Significant differences in digitizing noise were also identified between DS-AS (p < 0.001), DS-SS (p = 0.001), and SS-AS (p = 0.001). This study tested the scanning quality of an IOS fitted with different sleeves using absolute measures as opposed to relative measures, and though statistically significant differences were found, within the experimental conditions, the errors appear to be within clinically accepted limits. |
