Abstract: The present disclosure describes a dental implant with functional gradient and respective obtention method, wherein the implant comprises an inner part of metal or metal alloy or titanium-based metal matrix composite which comprises on its surface a transition zone of rugose texture or surface pattern; an outer part composed of a ceramic or zirconia-based ceramic composite, and a diffusion protective film between the transition zone and the outer part described as an oxide and/or nitride protective film.

Abstract: The present disclosure relates to a dental implant with electro-stimulation system by electric circuit comprising a plurality of overlapped discs wherein each disc comprises in its interior and in its upper end and lower end surfaces channels and respective holes, wherein each channel comprises an electrically conductive material comprised in said electric circuit. The channels further comprise a film that acts as a barrier between the material of the discs and the material of the electric circuit. The implant further comprises a battery or piezoelectric sensor that allows the creation of electric fields. This disclosure has the main advantage of stimulating bone growth throughout the whole surface of the implant as well as promoting an antimicrobial action through the electric fields.
