Implant-supported restorative therapy in a Swedish population

Replacing missing teeth through implant-supported restorative therapy is a common treatment procedure. While high survival rates have been reported, complications affecting the implant and/or the implant- supported reconstructions may occur. Such biological or technical complications require additional investment in treatment.
Out of a cohort of 596 subjects, the proportion of patients experiencing technical and/or biological complications over a 9-year period was 42% (Study III). One out of four patients experienced technical complica-tions, chipping being the most common. The extent of restorative therapy was the strongest risk indicator for technical complications (Study I). Patients diagnosed with peri-implantitis (n = 98) rarely received surgical therapy. Non-surgical interventions were insufficient in arresting disease progression (Study II). Accumulated costs during the observation period were significantly higher in patients with full-jaw restorations compared to patients with partial-jaw and single-tooth restorations. Among all complications, implant loss generated the greatest additional costs (Study IV).
