Relevance of tongue types and depth of the retromylohyoid fossa in fabrication of mandibular removable dentures - A clinical study

Abstract

Background: Successful denture fitting depends on three key factors: retention, stability, and support. While creating a denture for the upper jaw is relatively easy, the lower jaw presents more challenges due to greater issues with retention and stability. This is because dentures tend to move around relative to the underlying bone during use. To address this problem, a customized tool (an impression and cast) was used in a study to measure the depth of the retromylohyoid fossa. Purpose: The purpose of this study was to analyze the type of tongue and depth of the retromylohyoid fossa using an impression and cast. Materials and Methods: This study was conducted in the department of prosthodontics, where all patients received regular check-ups and dental treatments. The retromylohyoid fossa(extension) and tongue were examined in a sample of 500 patients aged between 20 and 50 years, and impressions were taken. Results: The measurements were recorded, and the depth of the retromylohyoid fossa was assessed. The tongue was also studied. Conclusion: This retromylohyoid fossa and tongue are a suspense itself, and our method is just a suggestion for the mandibular denture prosthesis success.
