Comprehensive Dual-Arch Prosthetic Rehabilitation with a Convertible Mandibular Cast Partial Denture and Maxillary Overdenture: A Case Report

Preservation of the residual alveolar ridge is a primary goal in prosthodontic rehabilitation. Overdentures represent a proven treatment modality that aids in alveolar bone preservation while maintaining proprioceptive feedback through retained natural teeth. Hemisectioned molars can serve as effective abutments for overdenture support. This case report describes rehabilitation using a maxillary tooth-supported overdenture and a convertible mandibular cast partial overdenture, using a hemisectioned molar as an abutment. A 62-year-old male patient reported with multiple missing teeth and difficulty in chewing. As the patient was not willing for extractions, a preventive prosthodontic approach involving tooth-supported overdentures was planned. The present case report highlights use of hemisectioned molar as an overdenture abutment. A convertible cast partial overdenture was designed to allow future modification in situation of abutment loss. This approach improves esthetics, mastication and overall patient satisfaction.
