Level Up Your Surgery: Meet Auxein’s Patient-Specific Implants (PSI)!

Are you ready for the next era of precision surgery? Say hello to Auxein’s Patient-Specific Implants (PSI)!

What is a PSI Implant?

A Patient-Specific Implant (PSI) is a customized medical implant designed to match the exact anatomy of an individual patient. Using advanced 3D imaging, CAD design, and precision manufacturing, PSI ensures better anatomical fit, enhanced function, and faster recovery compared to conventional implants.

Using advanced imaging (like CT scans) and cutting-edge 3D modelling and manufacturing (CAD/CAM and 3D printing), Auxein creates a perfect replica of the missing or damaged bone structure. This ensures a perfect, anatomical fit that matches your unique bone structure. 

Auxein PSI’s precision is vital in surgeries involving complex, delicate, and visible bone structures. They are primarily used in:

1. CranioMaxillofacial Surgery (CMF):

    • Reconstruction after trauma (e.g., severe facial fractures).
    • Correction of congenital deformities (birth defects).
    • Restoring facial symmetry and contour for aesthetic and functional needs (e.g., in the jaw, cheekbones, orbital, TMJ Implant).

2. Neuro Surgery:

    • Used for Cranioplasty (repairing skull defects) following trauma, infection, or surgery. The perfect fit is crucial for brain protection and excellent cosmetic results.

3. Onco Surgery (Oncological Reconstruction):

    • Reconstruction of bone removed during the resection of tumours (e.g., in the jaw, skull, Upper limbs, lower limbs e.g. pelvic, scapula, sternum etc.). This ensures both functional restoration and the best possible aesthetic outcome after cancer treatment.

The Auxein PSI Advantage: Unmatched USP

Auxein doesn’t just make custom implants; it pioneers the technology to make them better, stronger, and more precise than ever before.

  1. State-of-the-Art Manufacturing Technology: CNC Milling & 3D Printing
    Auxein utilizes a powerful dual-manufacturing approach for its Titanium and PEEK implants:
    • Precision Engineering: Advanced CNC Milling and 3D Printing ensure unmatched accuracy, superior density, and durability.
    • Pioneering Ultra-Thin PEEK: Auxein is a leader in using high-precision CNC Milling to manufacture ultra-thin 0.4 mm PEEK implants. This is a critical advantage, as 3D printing often cannot achieve this thinness while maintaining the required strength, density, and flawless surface finish essential for delicate CMF work.
  2. India’s 1st Patient-Specific 3D Printed Zygoma Implant
    Auxein has a history of innovation, including successfully performing India’s first patient-specific 3D printed Zygoma implant—a landmark achievement in complex facial reconstruction. This track record demonstrates their commitment to pushing the boundaries of what is possible in personalized orthopaedics.
  3. Regulatory Excellence & Quality Assurance
    Surgeons and patients can be confident in Auxein’s implants. Their commitment to quality is validated by the highest global medical standards:
    • ISO 13485: The international benchmark for Quality Management Systems for Medical Devices.
    • MDSAP (Medical Device Single Audit Program): Compliance with the regulatory requirements of multiple major global markets, ensuring the utmost safety and reliability worldwide.

Comparison: PSI vs Standard Stock Implant 

Feature

Patient-Specific Implants (PSI)

Standard Stock / Preformed Implants

Fit & Accuracy

Exact anatomical fit (mirrored from healthy side); minimal intra-op modification needed.

Require intraoperative bending/shaping; may not fit complex defects precisely.

Surgical Time

Reduced (shorter operation due to precise fit).

Longer (time consumed in adjusting implant during surgery).

Aesthetic & Functional Outcome

Superior contouring and symmetry; high patient satisfaction.

Often suboptimal results due to less precise adaptation.

Complications

Very low incidence of infection, displacement, or resorption (none reported in this study).

Higher risk of infection, resorption, displacement, and donor site morbidity (in autografts).

Customization

Designed for each patient using 3D planning and AM.

Generic, one-size-fits-most designs; limited adaptability in complex cases.

Materials

PEEK, UHMWPE, Titanium (biocompatible, durable, radiolucent options available).

Usually titanium mesh, silicone, porous polyethylene, or standard plates.

Auxein PSI: Beyond mass-produced, beyond standard. It’s the future of personalized surgery, delivering unparalleled fit, strength, and confidence to patients globally.
