When the TMJ disc gets permanently displaced, it can lead to limited jaw opening, often called a "closed lock." This condition can cause significant discomfort and makes it difficult to open the mouth fully.
✅ Key Points:
The displaced disc blocks the normal movement of the jaw, reducing the maximum opening to 25-30 mm or less.
Patients experience a hard stop and pain when trying to open their mouths wide.
Forcing the jaw open may worsen the displacement, making it harder to treat.
Understanding these mechanics is key to effective treatment and relief.
