Abstract
Purpose: The purpose of this study was to evaluate the repeatability of dental white light scanner.
Methods: The impression(Zerosil, Dreve, Germany) were digitized in white light scanner(Identica, Medit, Korea) to create 3-dimensional surface-models. The distribution of the discrepancies between the number of points in the corresponding CRM models and the point clouds in the others were measured by a matching-software(Power- Inspect 2012, Delcam Plc, UK). The discriptive statistics were used for statistical analysis(SPSS 20.0).
Results: The measurement of repeatablity showed very good reliability. The mean(SD) discrepancy value on the white light scanner digital models was 8.7(0.67) , based on SD and absolute mean values.
Conclusion: These in vitro studies showed that repeatability of dental white light scanner is high reliability. These results can be confirmed in further clinical studies.
