3D-Printed Complete Dentures for Patients With Limited Mandibular Residual Ridges: A Case Report

Digital workflows have revolutionized complete denture fabrication by enhancing precision, minimizing procedural errors, and improving patient outcomes in terms of fit, stability, and satisfaction. This case report demonstrates the integration of digital and conventional techniques in the rehabilitation of an edentulous patient who presented with severe mandibular ridge resorption. An 87-year-old male with impaired masticatory function and inadequate denture retention was treated using a comprehensive digital protocol that incorporated intraoral scanning, computer-aided design (CAD), and 3D printing technologies. Functional impressions and border molding were performed to capture dynamic oral tissue movements, and CAD software was employed to ensure precise maxillomandibular alignment. A trial denture was digitally designed, tested, and refined before the fabrication of the final prosthesis using 3D-printed materials. Retention was quantitatively evaluated using a digital force gauge, which confirmed significant improvements in the prosthetic performance. This case highlights the efficacy of digital dentistry in overcoming the anatomical challenges associated with edentulous ridges and underscores the need for further research to validate the long-term advantages of digital techniques in prosthodontics.
