Auxein Medical Publishes Study on Customized TMJ Implants to Improve Long-Term Stability

This research addresses the rising cases of TMJ dysfunction, which is increasingly linked to modern lifestyle factors, including dietary changes and stress. 

Auxein Medical has published a detailed study on custom-made Temporomandibular Joint (TMJ) implants to improve their stability and functional behavior over time. 

This research addresses the rising cases of TMJ dysfunction, which is increasingly linked to modern lifestyle factors, including dietary changes and stress. 

The TMJ, a hinge joint on either side of the jaw, plays a key role in speaking and chewing. Dysfunction in this joint can lead to significant discomfort and impaired function. With the growing number of people affected by TMJ issues, Auxein’s study offers promising insights into potential long-term solutions.

Advanced Implant Technology

Auxein Medical's study highlights the benefits of its Patient-Specific Implant (PSI) TMJ implants. These implants use CT scan data tailored to the patient’s anatomy, offering better adaptability and reducing surgery time. The implants aim to provide a more precise fit than traditional options, improving outcomes for patients undergoing TMJ replacement.

One of the major advancements in the study was the use of Finite Element Analysis (FEA) to evaluate stress and displacement in both bone and implant components. 

This method allowed the researchers to simulate the forces experienced during chewing and assess how well the implant distributed load across the jaw. The goal was to ensure the implant could handle stress without causing damage to surrounding bone structures.

Auxein’s implants incorporate titanium for the ramus (the vertical part of the lower jaw) and ultra-high-molecular-weight polyethylene (UHMWPE) for the fossa (the joint socket). 

Both materials were selected based on their ability to withstand the jaw's mechanical demands while adhering to ISO standards for safety and durability.

Simulation Shows Promising Results

The study showed that the von Mises stress values for both the titanium and UHMWPE components remained within safe limits under simulated conditions. This analysis is crucial because excessive stress can lead to implant failure or bone damage. Ensuring the implant distributes load evenly minimizes the risk of such issues.

Commenting on the study, Gaurav Luthra, Vice President Global Manufacturing and Regulatory Head at Auxein Medical, said: “This study emphasizes the biomechanical performance and material suitability of customized TMJ implants, marking a significant advancement in maxillofacial surgery. Integrating PSI technology and virtual surgery planning enhances precision and improves the quality of life for patients undergoing TMJ replacement surgeries.”

The study also used 3D printing technology to create anatomical models of the bone, allowing the researchers to fine-tune the implant design for each patient. This ensures a better fit, which can reduce recovery times and lead to improved long-term outcomes.

Impact on Maxillofacial Surgery

Customizing TMJ implants using patient-specific data is expected to transform how these surgeries are performed. By focusing on each patient's unique anatomy, surgeons can ensure the implant fits more naturally, leading to better functionality and a faster recovery. 

The material selection and design process used in Auxein’s study aims to provide a durable solution to reduce the likelihood of implant failure over time.

This research could offer a more reliable alternative to standard implants for patients suffering from TMJ dysfunction, potentially improving their quality of life. Auxein Medical's commitment to innovation in orthopedics continues to position it as a key player in the medical technology space.

“Our PSI implants promise greater precision, better fit, improved efficiency, reduced surgery times, and faster recovery, ultimately enhancing patient satisfaction,” the company stated.
