An implant for fixing dental prostheses, such as dental crowns, bridges, dentures or the like, including a support to be screwed into a receptacle prepared in the jawbone. The implant has a stump pin that is associated with the free end of the support; the support includes at least two portions: an apex portion, provided with a thread suitable to penetrate into the jawbone and provided with vertical slots for preventing rotation and for facilitating any removal, and a crown portion provided with annular micro-notches or micro-threads. The implant is mated to the stump pin conically, i.e., a male cone in the stump mates with friction with a female cone in the implant. This system has a slot that mates with a tooth to ensure an unambiguous mating position. In larger diameters, where there is enough space, there is also a male and female hexagon. |
