Abstract

Abstract: Objective: To investigate the clinical significance of multiple types of digital images matching and 3D printing technology in the treatment of condylar tumors. Methods: According to patient's spiral CT data, CTA data of blood vessels, 3D scanning data of teeth, the maxillary, mandible, soft tissue and condylar tumors with surrounding important anatomic structures were reconstructed using Mimics 21.0(Materialise, Belgium). Then, matching the 3D scanning of teeth with bones data from spiral CT, matching the soft tissue with bones. Finally, in the same coordinate system, the three-dimensional model of the maxillary and mandible complex with tooth information, condylar tumors and surrounding blood vessels were obtained. Designing and 3D printing splint was assisted operation. Results: All 6 patients were underwent the operation successfully with the wounds healed at the same time. The occlusal relationship of all patients were well. The postoperative CBCT showed that complete resection of tumors and no signs of recurrence were found in long term follow-up. Conclusion: Multi types digital image matching and 3D printing splint could accurately reconstruct the important anatomic structures such as condylar tumors and peripheral blood vessels, so as to fully understand the operation area before operation. At the same time, personalized 3D splint was designed to create space for operation and reduce the damage of surrounding tissues. This method could be used as an auxiliary way to treat patients with condylar tumors.
