Rehabilitation of masticatory function of an edentulous patient by application of duplicate dentures: A case report

Abstract

Patient: An 81-year-old woman presented with the complaint of masticatory dysfunction due to instability of the maxillary and maxillary complete dentures and pain during mastication. Masticatory dysfunction was diagnosed due to denture instability caused by deterioration of resilient denture liner and decreased occlusal vertical dimension caused by attrition of artificial teeth. Class II was identified by the JPS classification of symptoms. To transfer the present information of the existing dentures, the final denture was fabricated by making a duplicate treatment denture based on the existing denture.

Discussion: By using the duplicate denture, the form and function of the existing denture were transferred, and the patient’s complaint was resolved and quality of life was improved.

Conclusion: Masticatory dysfunction in an edentulous patient was improved by reflecting the information obtained from the treatment denture by using a duplicate denture in the fabrication of the final denture.
