[Type F hollow cylinder implant (I.T.I.)].

The single hollow titanium cylinder implant type F is here described. From october 1983 till october 1988, 187 implants were placed in 56 patients. It is possible to use this implant as a replacement for a single tooth or as abutment for a bridge. In case of extreme bone loss of the edentulous jaw, this implant is suitable to create retention and stabilisation for a denture. Up till now 180 implants are in function (96%); 7 implants were lost because of early failures.
