Dual-Arch Prosthesis: Revolutionizing Partial Dentate Rehabilitation

Abstract

The utilization of natural teeth as denture abutments offers a significant advantage in retarding the residual ridge resorption (RRR). This approach distributes stress concentration between the denture-bearing areas and abutment teeth, thereby mitigating issues such as loss of sensory feedback, compromised mastication, and aesthetic concerns. Overdentures, by providing additional support and stability, play a pivotal role in reducing RRR while enhancing stability and retention. A cast partial denture (CPD) becomes the first choice in cases of long edentulous span where cross-arch stabilization is required. The simplicity of insertion, removal, and maintenance, coupled with effective oral hygiene practices, make CPDs a practical solution. This case presentation illustrates the successful prosthetic rehabilitation of a partially dentate patient through the implementation of a maxillary overdenture and mandibular CPD underscoring the efficacy of this treatment modality in achieving optimal outcomes. The combination of these prostheses restored the masticatory function, improved the aesthetics, and enhanced the quality of life of the patient. This case highlights the effectiveness of dual-arch prosthetic solutions in achieving comprehensive rehabilitation in partially dentate patients.
