PROCEDURE FOR PRODUCING IMPLANTS WITH A PERSONALISED SURFACE that involves the cleaning/activation of the implant surface by means of plasma technology using oxygen or argon plasma to obtain surfaces with no organic compounds or oxide layers, and the application of a liquid solution that is designed for each patient and contains a single osteoconductive, osteoinductive, antibiotic, antibacterial or probiotic component, or a combination of any of them. The cleaning/activation of the implant surface by means of plasma technology may be carried out in the clinic or in the implant production plant and the liquid solution may be applied in the dental clinic just before the implant placement procedure.
