The face is not only the index of the mind but also houses vital organs like the brain and eyes, making treatment of facial injuries a complicated affair. The success of the facial reconstructive procedure is primarily based on the experience and expertise of the surgeon, but a wrong step in treatment can cause lifelong trauma. The reconstruction of a bony contour, discontinuity, or composite defect is generally based on the placement of either a bone graft or the use of an off-the-shelf implant or by using patient-specific implants (PSI).

Poly (Ether Ether Ketone) (PEEK) is a high-performance polymer that has high mechanical strength, biocompatibility, and has no cytotoxic activity. It does not induce adverse reactions to human tissues and causes no artifacts in post-operative imaging [1]. Apart from the above-mentioned benefits, PEEK also has mechanical properties similar to that of human cortical bone (thereby reducing stress shielding)

Moreover, PEEK does not conduct temperature like metallic implants.

Process of PEEK Implant Manufacturing

  1. The 2-Dimensional patient scan is refined, and a 3D dataset is created for 360-degree visualization. Our engineers use computer-aided design, or CAD, software to design the customized implant and/or surgical guide and/or anatomical model in three-dimensional space, which is further sent to the surgeon for approval.
  2. Once the virtual design is approved, the anatomical model is fabricated for mock surgical evaluation.
  3. Once the mock surgical evaluation is done and the implant design is approved, the customized PEEK implant and/or surgical guide is fabricated using Apium M220.
  4. The implant, along with the anatomical model and/or surgical guide, goes through rigorous quality control stages in compliance with the requirements of the ISO 13485. The cleaning, grinding, sterilization, and packaging of patient-specific implants and surgical guides are carried out in the company’s certified ISO Class 7 cleanrooms.
  5. After the post-processing and QC check, the implant, along with the model, is shipped to the surgeon or hospital.
