This large Swedish questionnaire survey conducted on a random sample of patients achieved a high response rate (83%) . Those who had received dental implant supported restorative treatment reported very high levels of satisfaction (94%). However, 31% had experienced implant related complications although only 6% reported that these complications occurred frequently.
