“…PPS is an area which can be located successfully by palpation, nose blow or phonation method without significant differences. 4,9,20,23,26,31,34 4. Determining posterior seal can be performed in final impression stage or scrapped on the master cast after correctly locating the area.…”

“…10,12,23,36 Clinically, different methods may result in different locations of the vibrating line. Chen 31 in his study on the reliability of methods to locate PPS reported that the vibrating line in the same individual observed by the nose-blowing method which is located slightly anteriorly than the vibrating line observed by the phonation method. But, the difference in the mean value between the lines identified was clinically insignificant.…”

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.

“…The palatal seal of the upper complete denture can be obtained by scraping the cast before denture processing, or by using physiologic impression technique or selective pressure impression technique [14]. [8] Stated that ''87.5% of dental schools teach the method of carving the PPS arbitrarily in the maxillary cast.'' Whereas [20] found that 95% of schools teach this method.…”

“…The PPS area has been defined as ''the soft tissue area at or beyond the junction of the hard and soft palates on which pressure, within physiologic limits, can be applied by a complete denture prosthesis to aid in retention'' [26]. The functions of the PPS of the maxillary complete denture include improving retention, performing sealing of the denture base with the underlying tissue and decreasing the gagging reflex [14,3,27] The PPS is performed by positioning the anterior and posterior vibrating lines [8]. [20,6] Stated that ''the one vibrating line concept for establishing the PPS is taught by 75-80% of schools.''…”

Objective: Providing sufficient posterior palatal seal (PPS) of a maxillary denture is necessary for retention. This research was designed to estimate the arbitrary scraping method used for establishing the PPS.Methods and material: Eight complete edentulous patients were selected. They received conventional complete dentures by using a scraping method for establishing the PPS. The posterior retention of the maxillary dentures was measured, the postpalatal area for each patient was visually estimated, and smears were made from the postpalatal areas at insertion appointment, 7, 30, and 90 days after denture placement.Result: The study revealed that the posterior retention of the maxillary dentures did not change during the stages of the study, and the epithelium of the postpalatal area converted gradually to a keratinized one.Conclusion: It is concluded that the scraping method used for establishing the PPS is an effective and safe technique.
