Guide Flange Prosthesis: A Case Report

Abstract

This article introduces the concept of guide flange prosthesis as a rehabilitative solution for patients undergoing hemi-mandibulectomy due to oral squamous cell carcinoma (OSCC). OSCC is a prevalent malignancy, particularly in India, necessitating surgical resection that often leads to functional impairments and aesthetic challenges. Mandibular continuity loss results in issues like mandibular deviation, occlusal plane rotation, and cosmetic disfigurement. The guide flange prosthesis, discussed through a case report of a 45-year-old male post-hemi-mandibulectomy, aims to stabilize the remaining mandibular segment, reduce deviation, and enhance chewing function. The article emphasizes the importance of comprehensive rehabilitation, especially when dental implants may be contra-indicated due to radiotherapy. The case involves the fabrication process of the prosthesis using perforated partial impression trays, irreversible hydrocolloid, and a stainless steel orthodontic wire substructure. The patient's successful adaptation to the guide flange prosthesis, providing stability and improved mastication, highlights its significance in the post-resection phase. The article also discusses the prevalence of oral cancers in India, surgical interventions, and the role of innovative approaches like guide flange prostheses in addressing the challenges of oral cancer reconstruction. Overall, the integration of surgical techniques and prosthetic interventions offers hope for enhanced outcomes in the complex landscape of oral cancer rehabilitation.
