Following the development of the BePIM project, the production of metal dental implants as a single piece using post technology was a success. In this project, the superficial modification of these microcomponents has as main objective to equip the surfaces with osteointegrating capacities. One-piece implants produced by the microinjection technique of metallic powders are feasible, both at a structural level (since they meet the limit for what is required for this application) and economical (associate manufacturing method (microPIM) with high series) and at the level of biocompatibility. In relation to the latter, the optimization of ceramic coatings that can improve the osseointegrating capacity of the implant is one of the objectives of the project. In this way, two important aspects were solved, the biocompatibility of the implant increased and the esthetic question related to the color of the coating. The medical devices selected for this development were dental implants, which are currently produced, unit by unit, by conventional metal machining technologies. The PIM technique, developed within the scope of the project, proved to be the most suitable for the manufacture of these dental implants, either in the sense of cost minimization or easy reproducibility of the product.
