Abstract

REIS, Bianca S; PORTELLA, Fernando F  and  RIVALDO, Elken G. Precision and accuracy of four current 3D Printers to achieve models for Fixed Dental Prosthesis. Acta odontol. latinoam. [online]. 2020, vol.33, n.1, pp.3-5.  Epub June 01, 2020. ISSN 0326-4815.

The aim of this study was to compare the accuracy and precision of 3D printers used to obtain models of fixed dental prostheses. A fixed dental prosthesis preparation was scanned and reproduced by four 3D printers: RapidShape P40, Asiga MAX, Varseo, and Photon. The impressions were scanned again, and the dataset was compared to the original dataset. Mean discrepancies (μm) were 52.97±20.48 (RapidShape P40), 68.27±43.53 (Asiga MAX), 62.22±56.21 (Varseo), and 80.03±28.67 (Photon). There was no difference (p=0.314) in accuracy; however, the precision differed (p=0.015) among the 3D printers. The printers had distinct precision but did not differ in accuracy.

Keywords : Dental models; Dental prosthesis; Threedimensional printing.
