An 8-year compilation of clinical results obtained with Steri-Oss endosseous implants

This 8-year study shows an increased success rate for Steri-Oss' osseointegrated implants in full, partial, and single-tooth edentation, compared to previous 5- and 6-year studies. A total of 1,499 implants placed in 389 women and 216 men had an average success rate of 96.1%. Of the 716 implants placed in the maxilla, 697 were exposed and only 31 failed-a success rate of 95.6%. Of 783 placed in the mandible, 750 were exposed and 25 failed-a success rate of 96.7%. Performance comparisons of Steri-Oss titanium threaded, hydroxyapatite-coated, cylindrical implants and titanium plasma-sprayed cylindrical implants showed, as in previous reports, a higher success rate for the coated and sprayed implants, especially for short implants placed in soft maxillary bone.
