Background Patients with Sjögren's syndrome are subject to loss of teeth related to the high caries risk. Dental implant therapy is often considered as a proper possibility for prosthodontic rehabilitation of SS patients, but the clinical outcome of implant therapy in SS patients is yet not well assessed.
Objectives To assess the clinical outcome of dental implant therapy in a cohort of well-classified patients with Sjögren's syndrome (SS).
Methods All SS patients regularly attending the University Medical Center Groningen for standardized follow-up in 2012-2013 (n=405) were asked by mail whether they were provided with dental implants. All patients met the revised American-European Consensus Group classification criteria for SS. Implant survival was noted. Periodontal indices and bone resorption were recorded clinically and radiographically. Patients' symptoms, health-related quality of life (HR-QoL), oral functioning and satisfaction were assessed using validated questionnaires.
Results Response rate was 82% (n=334). In total, 68 patients (20%) were provided with dental implants. In 50 out of these 68 patients clinical data could be collected. In these 50 patients, 144 endosseous implants had been inserted. Implant survival was 97%. Peri-implant tissues were healthy. Median marginal peri-implant bone loss was 0.7 mm (IQR 0.1-1.2). Patients were satisfied with their implant-retained prosthodontic rehabilitation, but oral functioning and chewing ability were impaired compared with healthy subjects. Worse oral functioning was associated with more dryness complaints, lower patients' satisfaction and worse subjective chewing ability.
Conclusions Implant therapy is a rather common phenomenon in SS patients as about one-fifth of the patients in our cohort of SS patients is provided with prosthodontic rehabilitation on dental implants. Considering the high implant survival, good peri-implant health, negligible marginal peri-implant bone loss and high patients' satisfaction, dental implants are a good treatment option in prosthodontic rehabilitation of patients with SS.
