Severe alveolar ridge resorption and mandibular torus in an edentulous patient undergoing rehabilitation by applying removable complete dentures with a soft denture liner using duplicate dentures: A case report

Abstract

Patient: The patient was a 74-year-old man with the complaint of pain in the mandibular basal seat mucosa. He was diagnosed with a masticatory disorder because of pain in the basal seat mucosa caused by severe alveolar ridge absorption and mandibular torus. New sets of complete dentures were made using a closed-mouth functional impression with duplicate dentures, and soft relining was performed on the mandibular denture.

Discussion: Using a duplicate denture enabled dentures to be made while preserving the form of the old denture. Applying soft relining to the mandibular denture prevented the accumulation of occlusal force on the mucosa in the mandibular ridges when using the bone ridges for denture retention. This improved the retention and support of dentures, occlusal force, and masticatory function.

Conclusion: For cases of severe alveolar ridge absorption and mandibular torus, applying soft relining and using an undercut of the mandibular torus are considered effective.
