We investigated pharyngeal cross-sectional dimensions during nasal breathing in six denture wearers with magnetic resonance imaging both with and without upper and lower dentures present. Significant increases in the velopharyngeal cross-sectional area were observed when dentures were present compared to the measurements taken when dentures were not worn. Our finding suggests that rehabilitation of the anatomy of the oral cavity contributes to pharyngeal airway maintenance during nasal breathing in denture wearers.

我们通过磁共振成像研究了六名假牙佩戴者在鼻呼吸时的咽部横截面尺寸，无论是否存在上假牙和下假牙。与未佩戴假牙时的测量结果相比，佩戴假牙时腭咽横截面积显着增加。我们的研究结果表明，口腔解剖结构的康复有助于假牙佩戴者在鼻呼吸期间维持咽部气道。
