Objective: The objective of this study was to evaluate the mean distance between the vibrating line and fovea palatinae in Class I, Class II and Class III Soft Palate types. Methodology: This study was conducted at Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences Karachi among 197patients. Duration of study was six months. All patients were examined for vibrating line clinically, assessed using phonation method. Subsequently, distance between vibrating line and fovea paltatinae was measured with uncalibrated compass in various contours of soft palate. Results: Out of 197 patient, the vibrating line was seen in130 (64%) anterior to fovea palatinae, whereas, 67 (34%) vibrating line was at the fovea palatinae. The mean distance of those anterior located vibrating line from fovea palatine was calculated as 2.13 (±0.82) mm in Class, 2.07 (±0.69) mm in Class II and 1.80 (±0.82) mm in Class III soft palate contours. Statistical analysis showed no significant between gender, while statistically significant difference among age group and mean distance of anterior located vibrating line from fovea palatinae were found. Conclusions: The mean distance of vibrating line which is predominately found anterior to the fovea palatinae was 2.07 (±0.77) mm.

“…On cast 2, a double bead design was carved as reported by Winland and Young (9). A groove similar to that on cast 1 was carved 1 mm anterior to the vibrating line .A second groove 1mm deep and 1mm wide at its base was then scraped just inside the anterior limit of the palatal seal area.…”

“…Another method, scraping the maxillary cast before final processing of the denture can be used to construct a posterior palatal seal. Therefore the posterior palatal seal takes on many various shapes, sizes and locations (9). Avant (17) reported a clinical study to evaluate the effectiveness of four different types of posterior palatal seals incorporated by scraping duplicate casts.…”

Background: In this study forces required to dislodge a maxillary complete denture were compared for different types of posterior palatal seals " Group 1 single beading design , Group 2 double beading design and group 3 with butter fly posterior palatal seal.Materials and Methods :Using a specially designed strain gauge force transducer and strain measuring device ,the force required to dislodge a maxillary complete denture measured and compared. Ten male subjects are selected with age range 55-65 yrs, the primary impression made in the usual manner and the final impression made with zinc oxide euogenol paste after the border seal made with tracing stick impression compound ,then the master cast duplicated using a heavy body silicone impression materials in order to produce a three additional casts, then the casts scraped to incorporate the posterior palatal seals and produce the three groups .a denture base constructed after postdum scraping.Results: Comparing the three groups the results shows that a significant difference found between the group 1 and 2 and group 1 and 3 with no significant difference found between group 2 and 3. Using ANOVA Table with LSD.Conclusion: No Design Provide superior priority than the other type of posterior palatal seals but a double beading and butter fly posterior palatal seal can improve the retention of a maxillary complete denture.

“…Posterior palatal seal area defined as area the soft tissue area at or beyond the connection of the hard and soft palates on which pressure, within physiologic limits, can be applied by a complete denture to help in its retention [15,16]. According to [17,18], there are various forms of it. Relief or spacer is a rest cut into the base of a denture to decrease or eliminate possible pressure on a specific area [19]; it may be used on the palatal surface of a complete denture with the intention of improving retention by creating negative pressure [20].…”

Complete dentures play an essential role in restoring oral function and improving the quality of life for individuals who have missing all their normal teeth. One of the key factors determining the success of complete dentures is their retention, which refers to the ability of dentures to stay securely in place during normal oral function. Adequate retention is essential for proper speech, mastication and overall comfort of the denture wearer. The study aimed to improve the retention of complete dentures through three different approaches: spacer, posterior palatal seal area, and undercut area. Three dentures were fabricated using the same steps, with variations in certain steps based on the retention technique being employed. The study showed that all three dentures had improved retention compared to standard complete dentures. The dentures that included the posterior palatal seal area and spacer demonstrated higher retention than the denture that employed the undercut technique. It is worth noting that the patient did not find the denture with the undercut technique satisfactorily.
