Summary

The objectives of this study were to compare the precision of two digital intraoral scanners from a series of repeat scan images, and to investigate the effect of the learning curve on changes in trueness when scanning the full arch of the oral cavity in actual patients.

Conditions

  • Tooth Diseases

Interventions

OTHER

impression data from reference scanner

To create a reference images for the assessment of the trueness, the impressions of the upper and lower arch of the oral cavities of four patients were taken using a polyether impression material (3M ESPE Soft Monophase; Minnesota Mining and Manufacturing Co.), and the intaglio scanning was performed on the impression body using a desktop scanner. Scanned images were transformed to the Standard Tessellation Language (STL) file format, and used as reference images.

DEVICE

iTero

The participants visited the dental clinic and performed scanning for 4 days. In order to investigate the difference in the precision and trueness of iTero intraoral scanners, the participants scanned the dental arch of a single patient 10 times using an assigned digital intraoral scanner.

DEVICE

Trios

The participants visited the dental clinic and performed scanning for 4 days. In order to investigate the difference in the precision and trueness of Trios intraoral scanners, the participants scanned the dental arch of a single patient 10 times using an assigned digital intraoral scanner. .
