An analysis of edentulous maxillary arch width and palatal height

This study involving 500 edentulous patients (250 males, 250 females) was undertaken to introduce a dimensionless factor termed the "palatal height ratio," defined as the ratio of the width of the edentulous maxillary arch to the height of the palate. The authors categorized the height, width, and anteroposterior dimensions of the edentulous maxillae. Measurements were made on diagnostic casts at five defined points. The difference between males and females was statistically analyzed and the variables were categorized. The results of this study may be helpful for a better standardization of the same variables in future studies.
