Abstract
Purpose: The purpose of this in vitro study compared to evaluation of repeatability of scanning abutment tooth stone
model and impression applied CAD/CAM ISO standard in dentistry.
Methods: To evaluate repeatability of scanning abutment tooth stone model, were repeatedly scanned to obtain 11 data
via 3D stereolithography (STL) files. 10 data (STL files) were compared with the first 3D data (STL file), and the error sizes
were measured by using 3D superimposing software(n=10). Also, the repeatability of scanning abutment tooth impression
was evaluated with the same procedure. Independent t test was performed to evaluate the repeatability of scanning
abutment tooth stone model versus impression through root mean square(RMS) and standard deviation(SD)(α=0.05).
Results: RMS±SD with regard to repeatability were 14.7±2.5㎛, 17.1±4.0㎛, respectively, with scanning abutment tooth
stone model and impression(p=0.129).
Conclusion: This study results showed a little different repeatability of scanning abutment tooth stone model and
impression applied CAD/CAM ISO standard in dentistry, will suggest futures good studies and clinical advantages.
