The posterior palatal seal area has remained a subject of controversy as far as the marking of the anterior and posterior vibrating lines are concerned. Sometimes, the dentures are over extended or under extended which will either cause discomfort to the patient or will be less retentive to horizontal forces. Then in order to improve its retention the dentist has to perform various corrective measures. This technique describes the visual location of the anterior vibrating line by considering the difference in the colour and variations in the anatomic contour of the hard palate with the corresponding soft palate which is a very important step in the fabrication of a complete dentures or any removable prosthesis requiring post damming.

Abstract


The posterior palatal seal area has remained a subject of controversy as far as the marking of the anterior and posterior vibrating lines are concerned. Sometimes, the dentures are over extended or under extended which will either cause discomfort to the patient or will be less retentive to horizontal forces. Then in order to improve its retention the dentist has to perform various corrective measures. This technique describes the visual location of the anterior vibrating line by considering the difference in the colour and variations in the anatomic contour of the hard palate with the corresponding soft palate which is a very important step in the fabrication of a complete dentures or any removable prosthesis requiring post damming.
