Osteoarthritis, a degenerative joint disease, can affect the temporomandibular joints (TMJ) responsible for jaw movement. It is caused by the breakdown of cartilage and subsequent changes in the underlying bone. Over time, the TMJ may experience wear and tear, leading to joint degeneration. Factors such as aging, previous trauma, misalignment, and genetic predisposition can contribute to the development of osteoarthritis in the jaw joints.




LeFort 1 Segmental Osteotomy. Bilateral Total Joint Replacement (TJR).

This patient experienced debilitating symptoms due to osteoarthritis. The degeneration of the joints led to severe pain and discomfort, especially during jaw movement. The bone-on-bone contact caused limited jaw mobility, resulting in a significantly reduced maximal incisal opening (MIO). Following the procedure, her maximal incisal opening (MIO) significantly improved, reaching close to 40 mm, enhancing her jaw function and overall quality of life.
