Within-subject assessment of swallowing threshold and efficiency for maxillary implant assisted overdentures with and without palatal coverage

Palatal coverage with maxillary implant overdenture negatively affected bolus formation during oral food processing. Increased chewing cycles and time of mastication lead to increase the viscosity of the bolus, which might cause aspiration during swallowing. Maxillary implant overdenture without palatal coverage may be a viable treatment option as it improve the oral food processing for safe swallowing. In addition, TOMASS test is easy to be incorporated as part of the clinical evaluation of swallowing efficiency for solid foods processing.
