In other cases, another painful medical condition such as fibromyalgia or irritable bowel syndrome may overlap with or worsen the pain of TMD.

At the initial consultation appointment efforts are made to determine whether or not the patient has symptoms which could be related to TMD temporomandibular Dysfunction.

To help determine if the lower jaw and the discs of the TM temporomandibular joints are in the correct position the following diagnostic tests are utilized:. This is specialized equipment used to take readings of the noises or vibrations occurring within the jaw joints upon opening and closing movements. The JVA is simply a 3-minute, non-invasive test where headphones are placed on both jaw joints and the patient is instructed to open and close six times.

An abnormal or dislocated joint has distinctive vibrations which can be analyzed to help diagnose the seriousness of the problem. There are basically 5 stages of disc displacement. Ideally, if there is a jaw problem you would hope that the patient is in Stage 1 or Stage 2 where the disc can be returned to its proper position when the patients wear a lower repositioning splint during the daytime.

If the JVA reveals that the patient is in Stage 3, 4 or 5, this is a much more serious problem and the prognosis is not as good for the resolution of all the symptoms. The first goal is to relieve the muscle spasms and pain as well as establish a normal range of motion of the lower jaw.

Sometimes how the teeth come together when the patient bites can cause muscle spasms, headaches, earaches and other painful symptoms as described earlier.

If the jaw moves side to side or forward there are interferences these sometimes cause muscle spasms and pain. These patients need to have a bite adjustment to correct the problem.

What is TMD? This occurs frequently when the patient jaw is located too far back.

There is noise or vibrations within the temporomandibular joints when the patient opens and closes and bites on the back teeth. This frequently means that the jaw is dislocated because the cartilage or disc is dislocated anteriorly or medially sideways. The ideal treatment would be to wear a daytime orthotic splint to try and recapture the dislocated disc. The resulting pain can be anywhere in the head and neck and mainly from the overuse of the temporalis muscle temple area and the masseter muscle side of face are as seen on the diagram.

What is the purpose of the TMJ? Masseter - this quadrangular shaped muscle is the most powerful of the four muscles of mastication. It has two parts and is responsible for lifting your mandible and closing your mouth. Temporalis - besides lifting the mandible and closing your mouth, this muscle is necessary to crush and grind objects between the molars. Medial pterygoid - with a quadrangular shape, this muscle is both deep and superficial.

Like the masseter and temporalis muscles, it elevates your mandible and laterally deviates it to the opposite side.
