Development of the fibrointegrated implant

The success or failure of the dental implant depends on the acquisition of the firm osseointegration. Eventhough, firm osseointegration was achieved, the defense mechanism of soft tissue around the implant does not exist further than the natural tooth and this is the reason why peri-implantitis is easy to be induced and always has the danger of the falling. From this point of view, the firm attachment of the connective tissue under the epithelium by fibrointegrated implant raised by this project seems to be important in order to prevent the bone resorption. The retrieval was advanced on the surface given to the implant cervix in order to artificially make the sharpy fiber. It had the ruggedness of about 3 μm as a surface shape on the implant surface, and information of being effective in order to form the organization that the implant as an aperture with the hole over 50 μm is sharpy fibers was obtained.On the surface quality with the effect in the fibrous attachment, the modification was studied. Surface design considering the surface charge was tried. It was possible that it conducted ion implantation processing (Ca+, N+, F+), anodization, titania low temperature thermal spraying processing, ion plating processing (TiN, Alumina), abrasion resistant surface treatment of ion beam mixing processing (Ag, Sn, Zn, Pt) to the pure titanium plate of the specularity and obtains basic data.The necessity of the development of the artificial saliva which will stop application of gargling and mouth rinsing medicine, induction of the antibody which stops the bacteria adhesion or bacteria adhesion including clinical application in future is indicated.
