简要总结
This is a comprehensive, long-term follow-up study of single-implant treatments. At the Brånemark Clinic in Gothenburg, Sweden, during the period of 1982-1985, 16 patients received single-tooth implants. This study evaluates the survival rate of the implants after nearly four decades, focusing on the biological and technical complications.
Of the original 16 patients with a total of 23 implants, 14 patients with 19 implants were available for the follow-up and were included in the study. Clinical and radiographic examinations were performed on these patients.
