Patient-Specific Orthopedic Applications


Porous Titanium Alloy Mandibular Implants

Description

This project focuses on developing custom-designed implants for jaw (mandibular) reconstruction using advanced 3D printing technologies. The goal is to create implants that closely mimic the natural structure and strength of bone, improving how well they integrate with the patient’s body.
The research utilizes state-of-the-art techniques like additive manufacturing to create implants made from titanium alloys, a material known for its strength and biocompatibility. 
To ensure the implants meet the demands of everyday use, detailed testing processes are performed to evaluate their performance under real-life conditions. This includes understanding how the implant will behave when exposed to various forces and loads over time.

This projects integrates the FEA modelling technique that was developed in a parallel  project to assess the mechanical integrity of the implants built using titanium alloy additive manufacturing (LPBF).
The implants are personalized for each patient, ensuring a better fit and more successful surgical outcomes. This work holds the potential to significantly improve the quality of life for patients requiring jaw reconstruction due to injury, illness, or congenital conditions.
