ABSTRACT:
Retention of a complete denture is the major factor to resist the forces of dislodgement along the path of insertion. In complete denture fabrication, fovea palatinae is the guideline for the posterior extension in the maxilla. Fovea palatinae mucous gland secretion helps in the retention by forming a thin layer within the maxillary complete denture.
OBJECTIVE:
The objective of this study was to assess the location of foveae palatinae in relation to vibrating line for developing posterior palatal seal to enhance retention of maxillary complete dentures.
METHODOLOGY:
The study was conducted in Sharif College of Dentistry in Lahore, Pakistan on a sample size of two hundred and fifty dentate, partially dentate and edentate patients with different age groups. Clinical examination of the maxilla was conducted for assessment of the vibrating line, whether it was at, anterior to or posterior to the fovea palatinae. The researcher used an indelible pencil to mark the ah line i.e vibrating line and its distance with fovea palatinae was measured.
RESULTS:
Results were concluded using SPSS Version 23. The fovea palatinae were mostly found to be located at 1.68 mm±1.11 anterior to the vibrating line. Thus, the dentists should assess this distance for the posterior extension of the maxillary denture.
CONCLUSION:
Fovea palatinae location in relation to vibrating line is an important landmark for posterior palatal seal in a complete denture. In the majority of cases, fovea palatinae were located 1.68 mm±1.11 anterior to the vibrating line.
