Abstract:
Objective:To introduce the clinical application of three-dimensional(3D) printed titanium alloy prosthesis in the reconstruction of mandibular defects.Methods:Three patients with extensive mandibular defects, who were either ineligible for or refused autologous bone transplantation were selected from the Oral and Maxillofacial-Head and Neck Oncology Department at School & Hospital of Stomatology, Wuhan University between April 2019 and December 2021. Preoperative oral and maxillofacial CT scanning was performed, followed by a virtual surgical plan and the design and manufacture of titanium mandibular prosthesis as well as the surgery guide-plate. Repair of mandibular defects using 3D printed titanium mandibular prosthesis. Follow-up after surgery to evaluate the patient’s functional and cosmetic recovery.Results:The study included three male patients aged 27, 10 years and 8 months, and 74 years, respectively. Two cases involved recurrent mandibular tumors postoperatively, and one case involved mandibular defects following gingival tumor surgery that affected the patient’s facial appearance and eating. All surgeries were successfully completed, with postoperative outpatient follow-ups at 36, 32, and 6 months, respectively. Follow-up indicated that the facial contours were basically symmetrical, the degree of mouth opening was normal, and the occlusion on the healthy side was essentially normal. No exposure, loosening, or fracturing of the prostheses was observed.Conclusion:3D printed titanium mandibular prosthesis can effectively restore the facial contour and mandibular function of patients.
