Objective: This study aimed to elucidate and evaluate the dynamics of swallowing when using different thickness palatal augmentation prosthesis (PAP) in healthy individuals. We observed changes in pharyngeal pressure during the swallowing process according to the wearing of PAP which was different thickness in healthy individuals using highresolution manometry (HRM).
Materials and methods: Ten healthy subjects (average age 34.2 ± 9.5 years) wearing a PAP of three thicknesses ingested water jelly and thin rice porridge. Maximum swallowing pressure and timing events were recorded with a 20-sensor HRM catheter.
Results: Healthy individuals that wore the PAP of 10 mm and swallowed jelly and thin rice porridge showed significantly increased maximum pressure at the tongue base and significantly decreased maximum pressure at the lower pharynx.
Conclusion: The thickness of PAP as 10mm enhanced the anchor of the tongue and increased the maximum pressure at the base of the tongue.
