Published trials evaluating long-term rates of survival and biological complications following computer-guided implant rehabilitation are rare.
This retrospective case series study1 assessed the long-term clinical success of implants planned with NobelClinician and inserted using NobelGuide (fully guided or pilot) in private practices. In total, 141 fully or partially edentulous patients received 694 TiUnite-surface implants between 2006 and 2015. All patients received NobelProcera CAD/CAM restorations.
Patients were followed for 1–10 years (mean of 4.8 years). Implant survival was 97.4% at 10 years. The prevalence of peri-implantitis was 2.8% (4 patients). Two cases of peri-implantitis were judged to be surgically triggered and two were diagnosed in patients with concomitant depressive disorders.
Authors attributed the high survival and low complication rates to adequate passive fit and a decreased risk of cement-related peri-implantitis due to customization of the cement line with NobelProcera.
