Aims and objectives: This article describes rehabilitation of mandibular partially edentulous arch in a patient who was dissatisfied with her previous partial denture. This case report discusses prosthetic rehabilitation after post and core of three mandibular teeth with minimal coronal structure and then using computer-aided design/computer-aided manufacturing (CAD/CAD) for the fabrication of the porcelain fused to metal (PFM) crowns and the cast partial denture framework. Background: In recent generation, the demand and awareness for quality treatment has been rapidly increasing. While treating a patient who is partially edentulous, principal attention is aesthetics, function and retention of the prostheses. Although attachments have a long history, many of the dental clinicians are hesitant to use these attachments in their day to day practice. The advantage of using these attachment-retained cast partial dentures is it improves aesthetics, provides comfort and function of the denture and at the same time fulfils patient's expectations. Case description: This case report describes 56-year-old female with the complaint of difficulty in mastication due to multiple missing teeth in the lower arch. It describes the clinical and the laboratory steps for prosthetic rehabilitation of a patient with mandibular partially edentulism using prefabricated metal posts, core build up, and cast partial denture with Preci-Vertix attachments. Clinical significance: This case report discusses a rehabilitation option for a patient who was unhappy with her previous prosthesis. The treatment planned here focuses on preserving the tooth present using post and core followed by fabrication of Preci-Vertix attachment prosthesis using CAD/CAM. Moreover, this resulted in prosthesis that was more precise with better retention and patient satisfaction.
