粘膜色素沈着を有する患者におけるカスタム完全義歯の特性評価：症例報告

Achieving a natural aesthetic outcome in completely edentulous patients is often challenging, especially when unique oral tissue characteristics such as mucosal pigmentation are present. Conventional denture bases may provide adequate function but frequently fail to reproduce individualized soft-tissue appearance, which can influence the patient's confidence, facial harmony, and social comfort. This case report describes a 72-year-old male with complete edentulism and pigmented keratinized mucosa in both arches. After standard denture fabrication, internal tinting techniques were used to characterize the denture base using heat-cure monomer mixed with specialized pigments. Layered coloration was applied to replicate the natural transitional shades of gingiva and alveolar mucosa. The processed prosthesis showed superior life-like texture and esthetics without affecting strength or fit. The patient reported improved appearance, comfort, phonetics, and masticatory efficiency, with no complications during follow-up. This technique demonstrates that internal denture base characterization is a simple, predictable, and cost-effective method to enhance the esthetic realism of complete dentures and can contribute significantly to psychological well-being and patient satisfaction.
