RESUMO
BACKGROUND: This study analysed the impact of oral rehabilitation with implant-supported fixed complete dentures (IFCDs) on the oral health-related quality of life (OHRQoL) and its relationship with self-esteem and gratitude. METHODS: 66 patients were interviewed to collect data on OHRQoL (OHIP-14), gratitude and self-esteem, after denture delivery. OHIP-14 scores were analysed over time and contrasted between groups with IFCD complication or not. RESULTS: OHIP-14 changed from 22.1 ± 13.8 at baseline to 1.8 ± 2.3 after rehabilitation. Gratitude and self-esteem mean scores were 38.6 ± 3.0 and 36.9 ± 3.8, respectively. OHIP-14 was statistically different from baseline (22.1 ± 13.8) and 1, 3 and 5 years after rehabilitation (2.3 ± 3.7, 1.9 ± 3.1 and 1.8 ± 2.3). No difference was found between the follow-up times and among OHIP-14 domains. Thirteen out of 66 patients (19.7%) had repairable prosthetic complications, but OHIP-14 did not differ between patients with or without complications. Gratitude and self-esteem showed a moderate association (rs = 0.36; P = 0.003), but no association with OHIP-14. CONCLUSIONS: IFCD treatment has a long-term positive impact on patient's OHRQoL, even among patients who had prosthetic complications. The long-term stability in improved OHRQoL is not associated with self-esteem and gratitude. © 2022 Australian Dental Association.
