Properties of pure titanium for dental implants fabricated by rapid laser forming

In the present experiments, pure titanium specimens fabricated by laser rapid forming (LRF) have been investigated, and based on the national standards (GB/T 13810-1997, GB/T 16886.5-2002), the mechanics properties, microstructure and cytotoxicity experiments were tested. The results show that tensile strength is 475 MPa, yield strength is 383 MPa, elongation is 27%, Vickers hardness is 188.4-206.3, and Young's modulus is 97.54 GPa. In vitro experiment, the cytotoxicity of LRF titanium specimens is grade 0. These data confirm that the LRF pure titanium can be efficient for surgical implants.
