Évaluation de la précision de l'impression 3D pour la fabrication de guides chirurgicaux en implantologie

Abstract : Surgical guides made by 3D printing are commonly used for computer-guided implant placement. However, their precision and reproducibility have not been studied in depth with the various additive manufacturing technologies and the materials used to manufacture them. The purpose of this study was to assess the accuracy and reproducibility of surgical guides made with different 3D printing technologies. Five different printing technologies were used in this study: SLA, DLP, FDM, SLS and Polyjet. Each type of guide (a “small range” and a “large range”) was printed 6 times with each printer, for a total of 72 guides. All guides were then scanned with a laser scanner. All scanned files were compared to the corresponding design file in surface matching software. The RMS average and standard deviation were calculated in the software and used to represent the accuracy and precision of the different printers used. The SLA technique presents the best print accuracy according to our study followed by DLP, Polyjet, SLS, FDM technologies. SLA and DLP techniques have shown better reproducibility than other technologies. There are also significant differences in printing depending on the size of the guide to be printed.
