Complete dentures may suffer from a lack of proper border extension, but most important of all is the posterior palatal extension on maxillary complete dentures. The posterior border terminates on a surface that is movable in varying degrees and not at a turn of tissue as are the other denture borders. Locating and designing of posterior palatal seal after thorough understanding of the anatomic and physiological boundaries of this dynamic region greatly enhances border seal and increases maxillary complete denture retention.
The diagnostic evaluation and placement of posterior seal are often given only minor attention in complete denture construction. This article reviews the importance of the posterior palatal seal with regard to its anatomy, location, design and placement.
