Masticatory function (MF) was assessed using the Swallowing Threshold Test (ST), with X50 and B cut\u2010off values indicating satisfactory performance. Oral health\u2010related quality of life (OHRQoL) was evaluated using the OHIP\u2010Edent questionnaire. The Posterior Mandibular Area Index (PAI) was analyzed using digital panoramic radiographs.

The number of IMO wearers presenting satisfactory mastication increased but persisted as unsatisfactory in nine participants by year 5. Declines in the Functional Limitation and Physical Disability domains of OHRQoL were noted, with unsatisfactory mastication correlating with higher pain (coef: 2.5; <jats:italic>p<\/jats:italic>: 0.03; 95% CI: 0.25\u20134.74) and psychological disability scores (coef: 0.94; <jats:italic>p<\/jats:italic>\u2009\u2264\u20090.01; 95% CI: 0.19\u20131.68).
