Evaluating the position of fovea palatinae in relation to posterior palatal seal in completely edentulous patients.
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 11
Abstract
Purpose: The purpose of this study was to examine and establish the relationship of fovea palatinae to anterior and posterior vibrating lines in completely edentulous patients.Materials and methods: One hundred and twenty completely edentulous patients were selected based on the inclusive and exclusive criteria. For each patient anterior, posterior vibrating lines and fovea palatinae were marked intraorally on edentulous maxillary arch and these markings were transferred to irreversible hydrocolloid impression. After pouring dental cast, digital vernier caliper was used to measure the distance between the midpoint of the fovea palatinae to anterior and posterior vibrating lines.Two examiners on every patient made all assessments independently and the measurements obtained were analyzed using statistical methods.Results: There was a significant correlation between fovea palatinae and posterior vibrating line (P value - 0.00001) and insignificant correlation between fovea palatinae and anterior vibrating line (p value 0.28). It was also observed that the average distance between the posterior vibrating line and anterior vibrating line with fovea palatine were 3.68 mm+1.78(S.D) mm and 0.21mm+2.6 (S.D) mm respectively. Conclusion: Within the limitations of the study, we can conclude that fovea palatinae is a reliable landmark for determining the posterior extent of the maxillary complete denture and in order to obtain a good peripheral seal for the retention, the maxillary denture should extend 2-4 mm beyond the fovea palatinae.
