Case Presentation:
For the master's thesis presentation, a novel methodology for bone graft surgery was developed. The advantages to the surgery were to reduce operational cost on commercial bone rings, personalized grafts which are bio-compatible to the patient.
Challenge Faced:
The traditional approach to bone graft surgery involves the use of commercial bone rings as implants. However, this method posed limitations and did not always provide optimal results. To address this, a novel technique was proposed, which involved surgically removing a precise portion of the bone ring from the patient's jaw and utilizing it as the graft material. Additionally, extensive design iterations were conducted to determine the most suitable location for the graft.
Solution/Approach:
The patient's data was initially segmented using Slicer software, allowing for isolation of the affected mandible. Subsequently, the resulting mesh file was imported into Blender software, where virtual planning was conducted. Through the use of animation, a surgical simulation was created, showcasing the proposed technique. This animated simulation was utilized during the thesis presentation to enhance understanding and visual representation.
To further demonstrate the feasibility of the proposed methodology, the resulting models were processed for 3D printing. Parts were printed using a multi-material resin, ensuring accurate replication of the patient-specific anatomy. The 3D printing process utilized an FDA-grade SLA printer, ensuring the safety and quality of the printed models.
