Abstract
Background: Mandibular tumors are complex and restoration of these resected regions of the mandible can cause defects which are cosmetically visible and can prove to be a challenge to restore functionally. The current practice of reconstruction with a free fibula graft and restoration of dental structures after 6 months can prove to be a challenge to patients. Also, the success of the reconstructed fibula flap depends on a variety of factors. Objectives: To plan and place a patient–specific implant “PSI” with immediate restoration of form and function and minimizing the need for additional surgical procedures like harvesting of flap. Methods: Using 3D printing technology and 3D designing software, a patient specific implant was designed and fabricated. Also, the surgery was planned using anatomic models and virtual surgery much before performing the actual surgical procedure. Results: As a single procedure, the resection and reconstruction of the mandibular segment was done with immediate replacement of the dentition. This resulted in a well restored form and better esthetics as compared to traditional reconstructive methods like fibula implant. Conclusion: The use of 3D technology to design and fabricate PSI facilitates better esthetics, better surgical outcome and earlier restoration of normal function for the patient. It avoids the needs for a second surgery.
