Abstract EN
There are various scanners available in dental practice with various accuracies.
The aim of this study was to compare the 3D capturing accuracy of scans obtained from Trios 3 and Dental Wings scanner.
A reference mandibular model was printed from FormLab with reference points in three axes (X, Y, and XY and Z).
The printed model was scanned 5 times with 3 scans: normal scan by Trios 3 (Trios 3A), high-resolution scan by Trios 3 (Trios 3B), and normal scan by Dental Wings.
After scan, the stereolithography (stl) files were generated.
Then, the measurements were made from the computer software using Rhinoceros 3D (Rhino, Robert McNeel & Associates for Windows, Washington DC, USA).
The measurements made with digital caliper were taken as control.
Statistical analysis was done using one-way ANOVA with post hoc using Sheffe (P<0.01).
Trios 3 presented higher accuracy than Dental Wings and high resolution showed better results.
The Dental Wings showed less accuracy at the measurements >50 mm of length and >30 mm in width.
There was no significant difference (P>0.05) of control with the Trios 3A and Trios 3B.
Similarly, for the measurements in Z-axis, there was no significant difference of control with each scan (Trios 3A, Trios 3B, and Dental Wings).
Accuracy of the scan is affected by the length of the scanning area and scanning pattern.
It is less recommended to Dental Wings scan >3-unit prosthesis and that crosses the midline.
