Frenum is considered as a normal anatomic structure in the oral cavity. However, it may exist intraorally as a thick broad fibrous attachment and/or become located near the crest of the residual ridge, thus interfering with proper denture border extension resulting in inferior denture stability, retention and overall patient satisfaction. The aim of this study was to assess the prevalence of high frenal attachment in edentulous patients. The present retrospective study was conducted among 355 edentulous patients reported to Saveetha Dental College and Hospitals, Chennai from June 2019 to March 2020. Data regarding the type of frenal attachment of the study participants was collected and the incidence was assessed. Frequency distribution and percentage and chi-square test were calculated. Among 355 edentulous patients, only 2 patients had high frenal attachment. The association between gender and high frenal attachment was not statistically significant. The present study showed that the prevalence of high frenal attachment in edentulous patients in the given population was less.
