Clinical Evaluation of Single-Tooth Restorations Supported by Osseointegrated Implants: A Retrospective Study
Ekfeldt, Anders / Carlsson, Gunnar E. / Börjesson, Gene
This retrospective study of Brånemark implants presents results from 93 implants for single-tooth replacements placed in 77 patients from 1987 to 1990. Only two implants were lost: one before the abutment operation and one during the first year in function. Patients' reactions to the rehabilitations were very positive regarding esthetic aspects and function. The most obvious problem was related to loose abutment screws. Forty-three percent of the abutment screws had to be retightened during the follow-up period, and for this reason, nine cemented crowns had to be remade.
