Abstract: An implant system comprising a body that defines a highly sharp conical end portion provided with a longitudinal milled section that continues as a cylindrical central portion, both portions having a trapezoidal-sectional thread and ending at the top in a truncated conical head that has a truncated conical cavity from whose bottom a threaded blind hole projects, the inner wall of the truncated conical cavity being thus provided with a plurality of projections lying in divergent planes that match its large diameter matching the coronal end and its small diameter matching the apical end, said projections having a triangular cross-section whose free edges are parallel to the annular surface of the cavity and have a rounded profile, said projections forming a star-shaped figure, and a prosthetic support structure being obtained in said cavity, having a truncated conical portion whose side wall has cross-sectional projections homologous to the projections of said cavity, said projections delimiting rounded-bottom
