Abstract

The complete denture prosthesis is retained in the mouth by a variety of factors; however, the maxillary complete denture retention is largely aided by the proper recording of the posterior palatal seal (PPS) area. Multiple techniques have been described in the literature, with many authors modifying them. However, the principles remain the same. This case report presents an unusual case where the posterior palatal seal area differed in size and extent between the right and left sides. In light of the same, the authors revisit different techniques of recording PPS areas. Various tray and spacer designs have also been discussed, along with their clinical indications and relevance. The patient reported a loose maxillary complete denture prosthesis, which was successfully replaced with a new conventional complete denture. Verification of the efficacy of the PPS area was performed at each subsequent clinical step after primary impression-making.
