Patient-Specific Implants in Maxillofacial Reconstruction - A Case Report

Abstract

Abstract Rationale: The successful utilisation of three dimensional (3D) techniques in engineering a titanium patient specific implant (PSI) for a patient who underwent hemimaxillectomy following post COVID mucormycosis infection. Patient Concerns: Issues related to problems associated with resection following mucormycosis, such as occlusal function, aesthetics and facial asymmetry. Diagnosis: The patient affected by mucormycosis was left with Aramany class 1 and Cordeiro type II sub total maxillectomy defect. Treatment: The patient was operated for mucormycosis followed by reconstruction with patient specific implant. Outcome: Positive clinical outcomes, including improved facial symmetry, function and psychological well being with immediate replacement of the teeth, the benefits of which far outweigh the traditional approach. Take away Lessons: The advances in the use of PSI by integration of 3D printing and computer aided design computer aided manufacturing (CAD-CAM) technology for extensive and challenging defects in the maxillofacial region have been highlighted in this case report.
