Technical complications following implant-supported restorative therapy performed in Sweden

• ObjectiveThe aim of this study was to evaluate the occurrence and consequences of technical complications in implant-supported restorative therapy. Material & MethodsThe occurrence and consequences of technical complications in implant-supported restorative therapy over a mean follow-up period of 5.3years were assessed based on documentation in files from 2,666 patients. Risk indicators were identified by the use of survival models, considering repeated events. Results were expressed as hazard ratios (HR) including 95% confidence intervals. ResultsTechnical complications occurred in 24.8% of the patients. Chipping and loss of retention were the most common, affecting 11.0% and 7.9% of supraconstructions, respectively, while implant-related complications (e.g., implant fracture) were rare. More than 50% of the affected patients experienced technical complications more than once and almost all reported complications led to interventions by a dental professional. The extent of the supraconstruction was the strongest risk indicator for both chipping (HR<0.2) and loss of retention (HR>3). ConclusionOver a 5-year period, technical complications in implant-supported restorative therapy occurred frequently and their management required professional intervention.
