Problems solved by technology

However, the surface of the titanium implant after EBM molding is relatively rough, and there are sharp burrs formed by the incomplete melting of the powder. At the same time, due to the existence of the porous structure, the powder residue is easily trapped inside the hole. If it is not removed, the implant will be damaged. The danger of powder wear and dissociation during long-term service can cause adverse reactions such as human poisoning and damage the normal functions of the human body.
