Paper Abstract

3D scans of dental arches and the 3D print technique in orthodontics have become every important part of clinical practice. The aim of our study was 3D objectification of stereolithography system (SLA) printed models in comparison with Fused Deposition Modeling (FDM), Polyjet (PJ) technology, and Selective Laser Sintering (SLS). The 50 scans of upper dental arches of medical students were prepared using 3Shape TRIOS 3. After then SLA 3D Printer Formlabs 2 built step by step layers of an upper dental arch model using liquid polymer hardened by laser beam (blue 405 nm laser). The study compared precision of 3D SLA, PDM, PJ and SLS models along all 3 axes.
