Enhancing outcomes of mandibular reconstruction by introducing three-dimensional printing

Abstract

Aim of the study. This study focuses on the advantages of including three-dimensional printing in the preoperative planning of mandibular reconstruction procedures following the removal of malignant tumors. Material and methods. We performed a retrospective study including patients with mandibular defects due to oncologic resections that underwent reconstruction procedures using stereolithic models in the preoperative stage. The general information, diagnosis, the technique of obtaining the stereolithic models and their use, as well as the type of surgical procedure and the outcomes were all documented. Results. In all seven included cases mandibular reconstruction was performed using a titanium reconstruction plate that was preoperatively shaped according to the 3D printed stereolithic models. The pre-bent plates adapted well to the defect intraoperatively. A decreased overall surgical time was noted. The aesthetic and functional reconstructive outcomes were favorable. Conclusions. The use of three-dimensional printing has proven advantageous in our experience for increasing the predictability and quality of the mandibular reconstructions.
