To determine the most posterior limit of the maxillary complete denture thru the position of vibrating line in relation with the fovea palatinae in complete denture patients visiting at tertiary care center.

Abstract

Introduction: Currently many new treatment choices are present but removable complete denture is still treatment of choice. Retention, stability and support are the essential qualities of removable complete dentures and for these to achieve, borders of the prosthesis should be harmonized contact with surrounding tissues to produces a seal and that seal is known as peripheral seal.
Objective: To determine the most posterior limit of the maxillary complete den-ture through position of vibrating line in relation with the fovea palatinae in com-plete denture patients visiting at Prosthodontics department of Isra dental college, Hyderabad.
Methodology: During this cross-sectional study from June 2018 to March 2019, 155 edentulous patients of either gender, having age ranges from 40-60 years and above were included. Indelible pencil was used for marking of vibrating line location and results of vibrating line location whether it is anterior, at or posterior to fovea palatinae were recorded in written proforma when patient pronounce the word “Ah” in normal unexaggerated manner.
Results: Among 155 edentulous patients, we found vibrating line anterior to fovea palatinae in almost 53% cases followed next in frequency it was found at the fovea palatinae in 46.5% cases.
Conclusion: Fovea palatinae is best anatomical structures to help in location of vibrating line and posterior palatal seal and vibrating line in most cases is located anterior to the fovea palatinae
Keywords: Fovea palatinae, maxillary denture, posterior palatal seal area, reten-tion and vibrating line.
