Introduction: A highly resorbed mandibular ridge poses an inevitable challenge for prosthodontists. Denture base is required to be extended adequately. A good and retentive set of dentures is a desirable outcome besides good aesthetic and functional values. Case report: A female aged 72 years visited our Hospital and reported about losing her old dentures. She required a new set of dentures. Her examination revealed highly resorbed mandibular ridge or an order V pattern of alveolar ridge resorption, as described by Atwood. Closed mouth technique was used to develop border molding, where the patient's muscle and muscular activity provided maximum support to the denture-bearing area. This technique aimed to obtain an accurate impression of undisturbed and uncompressed tissues. Impression using a soft liner has also shown a wider denture support area. A new set of dentures was confirmed showing good retention and stability despite the resorbed ridge, by functional and speaking examination. Discussion: Various methods have been used to achieve retention, stability, and support. The closed mouth technique was chosen owing to the stability of the material when stored. Conclusion: The proposed method is an excellent option to overcome highly resorbed mandibular ridge in a fully edentulous patient.
