Clinical results and guidelines on Steri-Oss endosseous implants.

A statistical study of the Steri-Oss implant system, concerning 673 implants placed in 280 patients in the course of a 5-year period, allows a therapeutic proposal to be made that will optimize the success rate of osseointegration. The study revealed indications specific to each type of implant, according to the depth and density of available bone. The use of titanium screws is recommended whenever bone quality is type I. In all other cases, where the density of bone decreases and approaches type IV, especially in the posterior maxilla, cylindrical hydroxyapatite-coated implants are recommended.
