Abstract :

Background: The use of fovea palatine, posterior viating line and other landmarks are normally used for locatingposterior palatal seal area which is an important clinical procedure for retention and determination of posterior extent of denture. Aim: Assessment of the position of fovea palatini in relation to posterior viating line and it�s correlation to arch form and palatal depth in edentulous patients visiting the Department of Prosthodontics. Objectives: 1. Evaluating the position and distance of fovea palatini in relation to posterior viating line and Maxillary arch form. 2. Correlating the distance of fovea palatini and posterior viating line with arch form. 3. Measuring the Palatal Depth and Correlating it to the measured distance between fovea palatini and posterior viating line. Materials and methods: Maxillary Impressions of 50 Edentulous subjects reporting to Department of Prosthodontics, Sinhgad Dental College and Hospital were made. Evaluating position and distance of fovea palatini in relation to posterior viating line and evaluating maxillary arch form and palatal depth was done using impressions and casts. Descriptive analysis and Pearson�s correlation test was used for statistical analysis. Results: About 66% of the casts showedposition of Fovea Palatini, anterior to posterior viating line and 34 % on the posterior viating line. Almost 13(26%) of patients had square arch form, 14(28%) had tapering arch form, 23(46%) had ovoid arch form. Shallow palatal depth was seen in 32% of the casts, normal in 64%, and deep palatal depth in 2%. Conclusion– From clinical point of view,Fovea palatine is usually anterior to the PPS. However it cannot be regarded as a reliable guide or landmark for location of posterior palatal seal area.
