Quantitative evaluation of the degree of palatonasal closure in patients with maxillary prostheses

Abstract

I quantitatively evaluated the degree or palatonasal closure for maxillary prostheses. The subjects included five healthy males aged 24 to 25 years, and 8 subjects with partial defects in the maxilla. Quantitative evaluation of the palatonasal closure level was possible by measuring and comparing the maximum pressure, the stable pressure inside the mouth, and the stable pressure maintenance interval and the pressure attenuation time while blowing and sucking before and after placement of the maxillary prosthesis.
