Preliminary experiments were carried out for the fabrication of dental root implants using an improved technique of laser processing of Ti powders. The proper-ties of produced samples were characterized for various processing parameters. Samples with rod and cone shapes were formed. A combined selective laser sintering (SLS) and selective laser melting (SLM) process was utilized. With this combination, the samples possessed a structure composed of two different zones, namely a remelted compact core and a sintered porous shell. The results of these experiments show that it is possible to produce dental root implants possessing the required geometry, structure and strength by appropriate laser processing of Ti powder.
