TMJ Derangement Disorder Treatment
TMJ derangement disorder implies that the joint movement is not coordinated which results in symptoms in the jaw such as joint pain, jaw locking. The jaw joint movement can be explained in three different scenerios:
- Usual TMJ movement: When the jaw moves, the movement in the joint involves the condyle rotating and gliding forward along the articular bone of the maxilla. There is a fibrous cartilage, called the TMJ disc, which lies top of the condyles and is attached by elastic ligaments. When the condyles move, the disc moves with it and prevents any friction between the condyle and the articular bone
- TMJ movement with disc displacement with reduction.
In about one-third of the population, the TMJ disc is slipped to the front of the condyle at rest. To open the jaw, the condyle moves forward and during this time, the disc slips back on top of the condyle and a click or pop is often heard by the person. During the closing of the mouth, the disc slips back out but the click may not be heard as the slipping out may be a subtle movement. Having a click does not mean a disorder or pathology.
- TMJ movement with disc displacement with locking.
In a small number of people, TMJ disc is slipped to the front of the condyle at rest and during movement. To open the jaw, the condyle moves forward and during this time, the disc stays in front of the condyle and at times prevents free movement of the joint.
