Background: The impact of treatments on completely edentulous individuals on masticatory performance (MP), oral health‐related quality of life (OHRQoL), nutritional status (NS) and socio‐economic profile (SP) is unclear in the literature. Objective: To compare the MP, OHRQoL, NS and SP of totally edentulous elderly users of bimaxillary complete dentures (CD) and users of lower implant‐supported fixed complete dentures (IFCD). Methods: Forty participants were allocated into groups according to rehabilitation treatment (n = 20): bimaxillary CD (G1) and lower IFCD, and upper CD (G2). The evaluation of MP used almonds by the method of sieves. Four questionnaires (Geriatric Oral Health Assessment Index–GOHAI and Oral Health Impact Profile Edent–OHIP‐Edent, Brazilian Economic Classification Criteria–ABEP and Mini Nutritional Assessment‐MNA) were applied to assess the OHRQoL, SP and NS of the elderly, respectively. After evaluating the statistical assumptions, the Mann–Whitney (α =.05) test was applied to compare the groups regarding MP, OHRQoL, NS and SP. Spearman's correlation (α =.05) was performed to verify the correlation between the MP, the OHRQoL and the NS of the participants. Results: G2 showed better MP (p <.05) in all masticatory cycles, OHRQoL (p <.05) and NS than the G1. However, the participants' self‐perception of oral health did not differ between groups (p <.05). A moderate negative correlation was found between MP and OHRQoL for 40 masticatory cycles (r2 = −0.513; p =.001). Conclusion: Individuals rehabilitated with IFCD had a higher average monthly family income and achieved superior behaviour in MP and OHRQoL, in addition to lower risks of malnutrition when compared to individuals using bimaxillary CD.

Objectives: The purposes of the present study were as follows: (1) to conduct a randomised crossover clinical trial to evaluate masticatory performance in wearers of conventional complete dentures in both arcs with conventional balanced occlusion (CBO) and lingualised balanced occlusion (LBO), using almonds as natural test food chewed for (a) 30 chewing cycles, (b) 40 chewing cycles and (c) until the subject felt ready to swallow and (2) to perform a randomised crossover clinical trial of oral health self‐perception through the Geriatric Oral Health Assessment Index (GOHAI) questionnaire. Background: During rehabilitation with full dentures, achieving stability and retention is essential for masticatory performance. A factor that can act is the appropriate occlusal scheme to be used, although the literature is full of discussions as to the most suitable occlusal scheme to be used, being CBO and LBO the most used in complete dentures. Materials and Methods: The clinical trial was conducted with 30 participants (14 males and 16 females; average age 65.8 years). A base of interchangeable posterior teeth in the lower dentures was used, thereby changing the occlusal schemes without needing to make another complete denture. The masticatory tests and GOHAI application were conducted in two sessions: first with each occlusal scheme, and second only after participants did not report discomfort with dentures. The analysis of variance for the mixed repeated‐measures test (ANOVA) was used to verify the results (α = 0.05). Results: The results showed no difference in masticatory performance according to the occlusal scheme (P =.519). The masticatory performance increased with the number of cycles (P <.001) tested, regardless of the type of occlusion scheme, and oral health self‐perception was higher after the second masticatory evaluation session (P =.027). Conclusion: The masticatory performance was similar between the two occlusal schemes, increasing according to the number of chewing cycles. The adaptive period is relevant, regardless of the occlusion scheme, because the time factor was decisive for the improvements noted in the oral health self‐perception of the participants (according to the GOHAI results).
