摘要： A dental implant supported on the cortical bone is implanted in the socket from which the tooth was extracted, if this hole still exists, or in the remaining socket when the tooth was extracted some time before, or alternatively in a hole made for placement of the implant, at cortical bone level, and externally, between the cortical bone and the gingiva, slightly embracing the mandible and the maxilla.
In one embodiment, in order to enhance the fixation and implant lifetime vascularization, the implant of the present disclosure for fitting in an intraosseous zone of a dental socket includes a plurality of raised platforms with a flat top such that said tops form an external surface of the implant for contacting with the intraosseous zone and the spaces between said platforms form a network of channels for revascularisation fluid flow with capillarity properties.

摘要： 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.

摘要： The present disclosure relates to a dental implant which comprises in its interior vertical and radial channels terminating in the form of holes in the lateral and lower surfaces of the implant and wherein each channel is filled by electrically conductive material in order to promote multiple electric fields along the surface of the implant. Electric fields range from 5 to 100 mv. A dental implant is described defining an axis along its length, obtained from a sintered block, which comprises in its interior longitudinal and radial channels which terminate in the form of holes in the surface of the implant and wherein each channel comprises an electrically conductive material for promoting multiple electric fields along the surface of the implant.
