An improved dental prosthetisation complex (10) suitable for eliminating bacterial presence therein comprising a dental implant (12) suitable for osseintegration, made from titanium or another biocompatible material, permanently inserted in the mandibular or maxillary bone (14) normally as far as the level of the bone crest (15) and provided axially with a blind hole (18), a transmucous collar (20), which axially prolongs the dental implant through the thickness of the gum (16), axially coupled to the dental implant (12) at the blind hole (18)and provided axially with a through hole (22), a stump (24) axially coupled to the blind hole (18) of the dental implant (12)through the through hole (22) of the transmucous collar (20) and provided with a part emerging (24") in relation to the gum tissue (16) suitable for providing support to an artificial crown (26) or other prosthetic structure, with said prosthetic complex wherein the coupling between said dental implant (12), transmucous collar (20) and stump (24) forms a monolithic complex which is mechanically and chemically sealed and stabilised inside by a cement (52) forming a complex impenetrable to organic fluids and to bacteria.
