Abstract

In this paper, two prototypes of dental elevator was made by DMLS process, using a super alloy powder of Co – Cr (ST2724G), with Phenix Systems machine, type PXS & PXM Dental, one with a threaded tail and another with a cylindrical tail. The quality obtained for the elevator is better, thanks to the material used and to the manufacturing process. For the elevator prototypes there were performed some Finite element method (FEM) analysis to identify stress locations and displacements. It was realized corrosion test in artificial saliva Fusayama Meyer (pH 5,5) at temperature of 37 ± 1 °C for 24 hours and remarks the importance of post treatment after DMLS process to obtain a better corrosion resistance in vitro.
