Abstract

Reconstructing defects after jaw tumor removal is difficult because of the complex facial skeleton, which affects patient nutrition and self-confidence. Traditional methods like iliac bone or fibula grafts take a long time and may raise aesthetic issues. Advancements in computer-aided three-dimensional (3D) modeling allow precise surgical planning, leading to more symmetrical reconstructions. Moreover, the application of custom-designed prostheses, similar to joint prostheses used in joint surgery, offers promising outcomes, particularly in cases involving the removal of the ramus and temporomandibular joint. A 28-year-old female had a maxillectomy for maxillary myxoma, using 3D-printed implants for reconstruction and dental rehabilitation. "Computer-Aided Design" software optimized implant coordination, reducing soft tissue pressure. Postoperative permanent dentures were successful with few complications. Compared with traditional methods, 3D-printed titanium plates improve patient satisfaction and reduce treatment time, particularly with sufficient soft tissue thickness, offering aesthetic benefits and eliminating extra surgeries for effective defect treatment.
