This document describes a case study of a new cast partial denture design for residual post-surgical cleft palate defects. Treatment of cleft palate patients requires coordination between medical and dental specialists. Despite surgical and orthodontic therapy, prosthetic treatment is often necessary to address missing teeth, deformed jaw segments, residual palatal defects, disproportion between jaws, and malocclusion. The new design aims to provide function, esthetics, and alleviate deformities by splinting mobile jaw segments. Impressions and frameworks were made, and the removable partial denture was tried in and adjusted to fit properly. The outcome successfully addressed the patient's deformities and improved esthetics and function.
