Total Joint

Replacement System

The anatomy, function and pathology of the temporomandibular joint is clearly the most complex of all the articulations in the human body. The history of alloplastic temporomandibular joint reconstruction has been characterized by multiple failures based on inappropriate design, lack of attention to biomechanical principles, and inattention to the exceptional wisdom of the orthopaedic experience.

Between 1992 and 1995, the design and testing phase of the Zimmer Biomet total mandibular joint
replacement system was completed. In the ten year clinical trial (from 1995 to 2005), over 400 prosthesis have been implanted with a patient success rate of over 96%*. The current indications for alloplastic joint reconstruction include:

  • Arthritic conditions: osteoarthritis, traumatic arthritis, rheumatoid arthritis

  • Ankylosis, including but not limited to, recurrent ankylosis with excessive heterotopic bone formation

  • Revision procedures where other treatments have failed (e.g. alloplastic reconstruction, autogenous grafts)

  • Avascular necrosis

  • Multiply operated joints

  • Fracture

  • Functional deformity

  • Benign neoplasms

  • Malignancy (e.g. post-tumor excision)

  • Degenerated or resorbed joints with severe anatomic discrepancies

  • Developmental abnormality
