    Introduction: The buccal vestibule is the area bounded by the alveolar gingiva, buccal mucosa, buccal frenum, and hamular notch. The range of vestibular width and depth can vary considerably among different individuals. Since resorption of the posterior edentulous arch begins from the buccal side as the edentulous residual ridge continues to atrophy, the vestibule becomes wider and shallower and the elliptical curvature of the vestibular fornix becomes less acute. When fabricating a denture, the buccal flange of the denture should fit into and fill the vestibular space. Mismanagement of the vestibular space can result in a number of significant problems. The extension of vestibular depth is important in complete denture fabrication for stability and retention. This study helps in knowing the extension pattern of buccal vestibular depth in partially and completely edentulous patients which acts as an important aid for the better success of denture fabrication. The aim of this survey is to assess the buccal vestibular depth among complete edentulous patients. Materials and Methods: A total of 100 randomly selected subjects with complete dentures, fabricated within the past 5 months, were examined. The subjects were patients in Saveetha Dental College. The depth and width of the buccal vestibule of each subject were measured at anterior (1 mm posterior to the buccal frenum) and posterior (1 mm anterior to the hamular notch). The anterior and posterior locations were marked with a eosin pencil. The denture was then inserted, and the reference marks were transferred from the alveolar residual ridges to the denture. Next, each subject was instructed to open their mouth half way and the cheek was illuminated with a mouth mirror. The depth of the vestibule was measured from the crest of the residual alveolar ridge to the fornix of the buccal vestibule with a periodontal probe. The differences between the dimensions of the maxillary buccal vestibule and the corresponding buccal flanges were analyzed by paired t-tests. The differences between the sexes were compared by two sample t-tests. The significance level was set at P < 0.05, and the data were analyzed with the statistical program JMP 7.0 software. Results: A total of 100 subjects were included in this study. The mean depth of the buccal vestibule increased from the anterior to the posterior region of the vestibule. The statistical mean results for each corresponding anatomic and prosthetic location demonstrated significant differences in depth. The difference in the mean vestibular depths and flange length in the posterior area was nearly 10.6 mm and 7.4 mm, respectively (P < 0.001). Conclusion: At each location, there was a statistically significant difference in the depth of the buccal vestibule when compared with the corresponding regions of the existing denture among the 100 subjects. The difference in the mean depth between the vestibules and the flanges in the posterior area was 10.6 mm and 7.4 mm, respectively (P < 0.001). The buccal vestibular flanges of the dentures were significantly inadequate in mimicking the depth dimensions of the buccal vestibule.
