The invention relates to a dental implant and a set of medical elements and devices usable, in principle, for accelerating the osteointegration thereof. The set may also be used for accelerating the osteointegration of another type of implant, but it may also be used by the persons that have already been previously inserted another type of dental implant, the ones suffering from chronical parodonto pathy, as well as by the ones in which the tissue resorption is due to the effects of ageing. The set may also be used by persons that did not have dentition problems but want to maintain the healthy natural dentition. In some first embodiments, the implant consists of a hollow external central rotation body (3, 6, 10, 13, 16, 18) which includes axially, in a first version a central rod (1) provided with an upper head (bi) or in another version, a central nut (7, 19), the rod (1) being provided at the upper head (bi), respectively the central nut (7, 19) being provided with a profiled cavity (b3l c4) for entraining the implant in rotation motion with a view to inserting the same and axially, with a threaded cavity (b4, c6) where the prosthetic blunt may be secured. The central body (3, 6, 10, 13, 16, 18) is also provided with an axial central space (a4, CO in which there will be arranged, even in the manufacturing process various elements made of biologically active compositions. The compositions may be of the known ones, but there may also be used ground human or animal tooth. They may be used alone, as simple elements or mixed with one another and may be used as such or may be used mixed in dental cements, augmenting materials and obturating materials. Medical devices may be made of such compositions, in which case the composition will be incorporated in a polar polymer, preferably a polymer having a higher polarity or at least equal to that of polyethylene. Some devices may be provided with a system heating the assembly and/or with an electronic system generating known
