PROSTHETIC REHABILITATION OF MUCORMYCOSIS PATIENTS USING DMLS FABRICATED CAST PARTIAL DENTURE WITH ALTERED CAST IMPRESSION TECHNIQUE—A CASE SERIES

Rehabilitating maxillectomy defects poses significant challenges that require tailored approaches for each individual patient. To achieve successful outcomes, it is crucial to integrate both traditional and modern treatment methods to enhance the prosthesis’s retention, stability, aesthetics, and functionality. Methods: Three patients with post-COVID Mucormycosis who had undergone localized debridement and partial maxillectomy were treated with a definitive rehabilitation plan. For patients with partial maxillectomy, a cast partial denture designed using Direct Metal Laser Sintering (DMLS) and the altered cast technique was employed. The defect areas were kept as hollow cavities (either closed or open) to reduce the prosthesis’s weight. Results and Conclusion: This approach to prosthodontic rehabilitation proves to be a straightforward and cost-effective treatment, significantly enhancing stomatognathic functions and overall quality of life for patients. Major challenges during rehabilitation include achieving retention and stability due to the absence of basal seat and hard tissue support. To address these challenges, a combination of conventional and digital techniques was utilized to ensure precise fitting and accuracy of the prosthesis, thereby minimizing treatment time and the number of patient visits.
