AUTHOR(S): Reem Abdulrahim, Tuğçe Kavaz and Nuran Yanıkoğlu
The posterior palatal seal of maxillary denture is an important aid in the retention of the upper prosthesis.
Objectives: The purpose of this article was to introduce two alternative techniques for posterior palatal seal (PPS) registration. These different methods were evaluating the best way to create the area of maxillary posterior palatal seal with more practical approach for routinely clinical measurement in term of posterior retention.
Materials and Methods: In this study the following materials were used: (Elite Hd + Putty Soft (Normal Setting), (Elite Ortho: Gypsum Type III White – Zhermack) for taking primary impression and poured the diagnostic cast. (PATTERN RESIN LS Self-Curing, Acrylic Die Material) to make special tray for each patient. Two different technique to copy the post dam area to the secondary cast were applied; (Cera Reus Pink Impression Wax) The second technique was by applying cold cure acrylic resin. Locate and delineate the anterior and posterior on the soft palate. At time of insertion the evaluation of posterior retention area was made for each two finished maxillary denture and by three different dentists.
Conclusions: Scraping method for establishing the area of post dam with different registration materials is an effective technique for improving posterior retention of maxillary denture.
