Retaining natural teeth as abutments for dentures can significantly reduce progress of residual ridge resorption. The stress concentration can be shared between the denture baring areas and the abutments. Overdentures can decrease the impact of residual ridge resorption; provide sensory feedback, loss of occlusal stability, loss of esthetics in addition to compromised mastication. In order to reduce residual ridge resorption and to increase retention and stability, overdenture as a treatment modality has been successful. When edentulous areas too extensive or too numerous for fixed prosthesis and need for cross arch stabilization cast partial denture is preferred. Insertions as well as taking away of the denture and regular oral hygiene are simple to perform. Present paper depicts the rehabilitation of partially edentulous mouth with maxillary cast partial denture and mandibular tooth supported overdenture.
