Abstract: Objective: To investigate the clinical feasibility of simultaneously treating osteochondroma of the mandibular condyle and its resultant dento-maxillofacial deformities with 3D printed surgical templates. Methods: Virtual surgical simulation was performed according to the imaging data by using two softwares, Dolphin Imaging 11.7 Premium and Mimics software. Surgical templates were fabricated by 3D printing to guide the surgery. The linear differences between virtually simulated and postoperative skull models were evaluated. Results: Successful rehabilitation of condyle function, normal occlusion, and symmetry of the facial profile were achieved in all patients. The linear differences of the incisors and first molars were no more than 1.4 mm, and the greatest difference was found at the mentum, which was up to 2.4 mm, demonstrating the accuracy of the new method. Conclusion: The results suggested that virtual surgical planning and guiding templates facilitated accurate diagnosis, treatment planning, accurate osteotomy and repositioning of bony segments in the treatment of condylar osteochondroma and its resultant facial asymmetry.
