Mauland E K, Bull V H, Melbye E L, Verket A. Patient-reported outcomes following dental implant rehabilitation according to reason for missing teeth: A survey from a Norwegian population 8 years following treatment. J Clin Periodontol 2023; DOI: 10.1111/jcpe.13895.

Self-report of complications and lack of pre-treatment information were the strongest predictors of inferior patient satisfaction and predicted inferior oral function.

This study aimed to assess patient-reported outcomes (PROs) 8 years after dental implant rehabilitation in a sample with tooth loss due to periodontitis (TLP) and a sample with missing teeth for other reasons (MTOR). The Norwegian National Insurance Scheme registry of subsidised dental implant therapy was searched, and patients (n = 3083) rehabilitated with dental implants in 2014 were sent a questionnaire. Of the respondents (n = 1299), more than 90% were partly or fully satisfied with the treatment outcome. Complications were reported by 44%. Patients who lost teeth due to periodontitis (n = 784) reported greater oral function improvement and better pre-treatment information, and were more likely to experience complications when compared with patients who lost teeth for other reasons (n = 515). Age, level of education, self-funded cost, pre-treatment information, history of complications and the reason for missing teeth were found to predict PROs.
