Abstract
AbstractPurposeTo investigate the influence of different denture‐bearing conditions on the masticatory function and patient‐reported outcome measures (PROMs) of complete denture wearers.MethodsSixty edentulous patients were selected and allocated into two groups according to the American College of Prosthodontics' (ACP) classification: non‐atrophic (NAT) (Classes I and II) (n = 24) and atrophic (AT) (Classes III and IV) (n = 36). All patients received new complete dentures (CDs). The objective variables (masticatory performance and swallowing threshold) were assessed as well as the PROMs (oral health‐related quality of life (OHIP‐EDENT), patient satisfaction) and quality of the prosthesis, at baseline (using the old CD) and after 4 months new prostheses use. Data were analyzed by Mann–Whitney test followed by the Generalized Equations Estimation (GEE), linear regression and Chi‐square test.ResultsHigher masticatory performance was observed in the NAT group (p < .05) for both time points, baseline and after 4 months. However, compared to baseline, both groups showed significant masticatory improvement after 4 months (p < .05). Satisfaction and overall quality of life improved after 4 months with no difference between groups (p > .05). Regarding the quality of the CD, baseline results were significantly (p < .05) lower in the AT group, but after 4 months, no significant differences were found between groups and in intragroup analysis (p > .05).ConclusionsThe denture‐bearing conditions seems to impact masticatory function, but the PROMs are barely affected.
