TMJ Replacement

Dr. Lohr is extensively trained to provide patients with total temporomandibular joint replacement. Joint replacement may be required due to the following problems:

    • Facial asymmetry or jaw growth abnormalities
    • Joint ankylosis or limited jaw mobility
    • Advanced TMJ osteoarthritis
    • Failure of a previous TMJ reconstruction
    • History of TMJ trauma
    • History of TMJ pathology or infections

There are currently two FDA-approved alloplastic temporomandibular joints available in the Unites States. Dr. Lohr is certified to offer both types of joints at KC Facial & Oral Surgery. 


TMJ replacement with alloplastic devices has existed since the 1960s. Numerous devices were designed through the 1980s and placed into thousands of joints for the same reason joint replacements are used today. The “modern” TMJ alloplastic implants by TMJ Concepts and Zimmer Biomet have been around since the 1990s and are backed by decades of research and clinical use. Drs. Lohr and Hollabaugh are qualified to place both implant systems and have extensive experience with removing all older joint replacement systems. 

The two current joint replacement systems today are:

  1. Zimmer Biomet – stock TMJ prosthesis
  2. TMJ Concepts – custom (patient-specific) TMJ prosthesis

Each system has indications for use which Dr. Lohr will discuss with you if you are recommended to receive a joint replacement. 


Your first appointment with us will be a consultation where Dr. Lohr will evaluate your TMJ problem. Fortunately, most TMJ problems do not require surgery but may require medications, physical therapy, splints, or special diets. Once determining the cause of your TMJ problem, we will let you know what treatment we recommend, educate you about the recommended treatment and discuss all questions you may have about your diagnosis or treatment.

Patients who require a TMJ replacement may experience the following symptoms or problems before seeing us:

  • Facial asymmetry or jaw growth abnormalities
  • TMJ pain
  • Limited mouth opening
  • Previous trauma or surgery
  • Previous TMJ reconstruction


Dr. Lohr performs this procedure under general anesthesia in a hospital setting. We provide multiple modalities to ensure comfort after this procedure. Patients are admitted post-operatively to the hospital and stay 1-2 nights to ensure pain is well controlled before going home. As with all procedures, before the surgery we will extensively review all aspects of the surgery, post-operative instructions and address any questions or concerns that you may have about the procedure.
