Introduction: Determining the posterior extent of maxillary denture is an important factor for retention and patient comfort. Among the landmarks, fovea palatina are utilized to extend the posterior denture border as an indicator of posterior palatal seal. The spatial relationship of fovea palatina to the posterior vibrating line has variations and is related to the types of soft palate. Aim: The aim of this study is to investigate the relationship between clinically determined posterior vibrating line and fovea palatina in Nepalese population and also compare the variations among the different types of soft palate. Materials and Methods: In 140 edentulous patients (57.1% male, mean age = 65.78 years), fovea palatina and posterior vibrating line were marked, and the distance between them was recorded. The comparisons were made in palatal types and gender as independent variables. The level of significance was 0.05 (95% confidence interval). Results: The mean distance of posterior vibrating line from the fovea was found to be 3.43 mm posteriorly. Statistically significant difference (P < 0.05) was observed among Class I, II, and III soft palate types in the distances measured from the fovea palatina to the posterior vibrating line. The gender showed no statistically significant difference. Conclusions: The fovea palatina was located more posteriorly in the Nepalese population and can be used cautiously for locating the posterior extent of maxillary denture.
