The Haryana State Council for Science, Innovation, and Technology has awarded a grant of Rs 35 lakh for a 2023-24 research and development project titled “Optimizing Process Parameters for Medical-Grade PEEK Material in Craniomaxillofacial Prosthesis Using Hybrid Algorithms to Assess Mechanical Properties.”
Polyether Ether Ketone (PEEK) is a 3D-printable material that allows for the creation of intricate shapes and profiles of human anatomy through fused deposition modeling. This capability facilitates the production of prototypes and allows for the testing of maxillofacial prostheses before surgery, aiding in pre-surgery planning.
PEEK implants, designed digitally and customized for individual patients, show improved clinical outcomes in restoring cranial defects. The use of PEEK is expected to reduce surgical time and risks, promoting faster patient recovery.
Dr. Deepak Chhabra, the Principal Investigator of the project and Associate Professor in the Department of Mechanical Engineering at Maharshi Dayanand University’s University Institute of Engineering and Technology, Rohtak, explained, “Our project focuses on using PEEK material for dental implants instead of the traditional titanium. PEEK offers similar osteo-conductive properties and an elastic modulus close to human bone, making it a viable alternative.”
Dr. Virendra Singh, Co-Principal Investigator and Senior Professor and Head of the Department of Oral and Maxillofacial Surgery at PGIDS, Rohtak, noted that PEEK-based, digitally designed implants have shown greater clinical efficacy in repairing cranial defects. He added, “Using PEEK material not only shortens surgery time but also reduces risks and supports quicker patient rehabilitation.”
The research also suggests that PEEK could be used to precisely fabricate lumbar cages, rods, and screws for spinal implants, providing strength and stability to the spine and ensuring steady bone fusion.
The project aims to reduce the need for extensive equipment and materials, streamlining the production process.
