<title>Fabrication of titanium dental implants by selective laser melting</title>

Abstract

The present paper will discuss the influence of the processing parameters on the characteristics of titanium models built by Selective Laser Melting. The microstructure and the fatigue strength of the three dimensional titanium models formed by Selective Laser Melting with an Nd-yttritrium-aluminum-garnet (YAG) pulsed laser are investigated. In order to increase the wear resistance of titanium models, surface alloying via laser-gas-nitriding (LGN) is applied. The mechanical properties of the models built by laser forming are adequate for fabrication of dental implants.
