This paper presents a case study of pre- and mid- surgery supplies in the field of maxillofacial surgery. The operation involved the process of resection within the mandible and the implantation of a joint endoprosthesis. The methodology is based on medical data in DICOM format and a maxillofacial model in STL format obtained through structural scanning. The stages of work included processing medical data involving medical imaging segmentation, structural scanning, model design and their production using 3D printing. SLA technology and various materials for each model were used in the process. The entire process underwent clinical validation during the mandibular reconstruction surgery and analysis of the obtained results. Satisfactory maxillofacial models were obtained, allowing for precise positioning of the endoprosthesis and planning of the surgical procedure, while the individually tailored guides and templates were used during the surgery. The models significantly improved the quality of the surgery, shortened its duration, and accelerated the patient's recovery.
