Temporomandibular joint reconstruction (TJR)
Temporomandibular joint reconstruction (TJR) refers to a patient-specific, customised implant designed and manufactured specifically for an individual patient based on their unique anatomy. The use of PSI in TMJ replacement involves advanced imaging techniques to create detailed three-dimensional models and to design a customised implant that closely matches the patient’s anatomy, taking into account factors such as the shape and size of the joint components.
Imaging: patient data acquisition from high-resolution imaging (CT or MRI)
Design: The implant is designed to fit precisely into the patient's anatomy. This may involve creating a replacement joint disc, reshaping bone surfaces, or designing other components as needed.
Surgery: The patient undergoes surgery, during which the TJR is placed in the TMJ to replace the damaged or dysfunctional joint components.

Virtual Planning: Using specialised software, surgeons and engineers create a virtual model of the patient's jaw, which serves as the basis for implant design.
Manufacturing: Once the design is finalised, the customised implant is manufactured using advanced technologies like 3D printing or computer numerical control (CNC) machining.
The potential benefits of custom-TJR include a better anatomical fit, potentially reduced surgery time, and improved postoperative outcomes. By closely matching the patient’s anatomy, these implants may contribute to a more natural joint function and reduce the risk of complications.
