Conventional complete dentures (CD) supported by the alveolar ridge was the most usual treatment for edentulous patients who potentially experiencing limitations (i.e. financial or systemic) preceding implant treatment. So, considering the important role of these treatment and the poor methodological quality with high or unclear risks of bias of studies, which can limit data analysis, this controlled clinical trial (RCT) was proposed. The aim was evaluate the impact of complete dentures on masticatory performance, oral health-related quality of life (OHRQoL) and satisfaction in young older people (60 years or more) after 3 months of new dentures. For the RCT, 50 randomly randomized participants were selected and divide in two groups: teste group (n = 25) and control group (n = 25). In the test group (TG), new complete dentures were fabricated. In the control group (CG), new CDs were not fabricated and data for old denture were collected twice within 3 months. The dependent variables were masticatory performance (X50), OHRQoL and satisfaction. The masticatory performance was analyzed by the particle size analysis, after chewing an artificial test food. The weight retained in a sieve group determined the median particle size (X50). OHRQoL was obtained by applying the OHIP-Edent and the satisfaction was evaluated in relation to chewing, taste, speech, pain, aesthetics, adaptation, retention and comfort. A 5% significance level and 80% power were assumed in all tests. The final sample consisted in 48 older adults, with mean age of 68.77 years (± 6.01). The most was female (n = 41; 85.4%) with time of edentulism 26,41 years (± 12.37) and mean time of use the old dentures of de 9.22 years (± 5.10). The mean masticatory performance (X50) was 6.67 mm (± 0.42) in T0 and 6.58 mm (± 0.55) in T1. No significant difference was found 3 months after the new dentures compared to old CDs. In TG, the total OHIP significantly reduced after treatment, indicating an improvement in OHRQoL in the elderly who received new dentures. This reduction was also significant for the domain’s functional limitation, physical pain, psychological discomfort, physical dysfunction and psychological dysfunction (p < 0.05). For the variable satisfaction, the overall score obtained after insertion of new dentures increased significantly, from an average of 59.04 points to 93.82 (p < 0.001). Thus, from the results, it can be concluded that, even without increasing the masticatory performance of the elderly in a 3-month period of use the new CDs, this treatment showed positive aspects regarding the improvement in quality of life and satisfaction in this population.
