Evaluation of the accuracy of the resection template and restorations of the bone structures in the mandible area manufactured using the additive technique

The article presents the current possibilities in the field of modeling and manufacturing models of anatomical structures, surgical templates, and implants in terms of planning surgical procedures in the area of ​​the mandible. In the first stage, the 3D reconstruction of the mandible geometry using the 3D-Slicer software was presented. The next step of the process consisted in modeling resection templates and supplementing the loss of the bone structure of the mandible. The last stage consisted of manufacturing models using the additive FDM method from PC-ISO material and performing an accuracy assessment. The models' accuracy using the additive FDM technique is within the tolerance range of +/- 0.2 mm. It is sufficient to use models when planning a procedure.
