The masticatory performance was evaluated through continuous mastication of a special device called a biocapsule. The Brazilian Oral Health Impact Profile (OHIP\u201014Br) questionnaire was used to assess the oral health\u2013related quality of life. The Student <jats:italic>t<\/jats:italic> test was applied for independent samples (<jats:italic>P<\/jats:italic> &lt;0.05) to evaluate the masticatory performance, and the Mann\u2010Whitney <jats:italic>U<\/jats:italic> test was used to determine quality of life (<jats:italic>P<\/jats:italic> &lt;0.05)<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> There was a statistically significant difference in masticatory efficiency between groups (<jats:italic>P<\/jats:italic> = 0.006). Statistically significant differences were also observed in the following parameters: 1) physical pain (<jats:italic>P<\/jats:italic> = 0.003); 2) psychologic discomfort (<jats:italic>P<\/jats:italic> = 0.008); 3) physical disability (<jats:italic>P<\/jats:italic> = 0.033); and 4) OHIP\u201014Br total score (<jats:italic>P<\/jats:italic> = 0.001). The control group achieved the best indicators. Both the masticatory performance and quality of life indicators showed significant correlation with the alveolar bone height.<\/jats:p><jats:p><jats:bold>Conclusion:<\/jats:bold> The loss of
