If you are contemplating major dental procedures such as re-construction, cosmetic dentistry, orthodontics, dentures, or if you suffer head/neck pain or other TMJ – like symptoms, your choice of treatment becomes very important.
Your bite, or occlusion, is simply the position of your jaw when your teeth are together. Seems like a fairly basic idea, but your occlusion is very important and can affect your health in many ways.
Until recently most dentistry has been based on the assumption that wherever your bite naturally was (habitual occlusion), that was the correct position. Today most dental treatments are still planned from the patient’s existing or habitual occlusion. Because sometimes the habitual jaw position is a reasonably good position and because our body systems are often adaptable to less than ideal circumstances, many of these procedures have an acceptable result. However, there are also many times that treatment procedures carried out with “textbook” accuracy do not produce a result that is fully functional and comfortable.
The growing field of neuromuscular dentistry goes beyond using your habitual bite as the basis for planning treatment. Neuromuscular dentistry considers the entire system that controls the positioning and function of your jaw. The neuromuscular dentist seeks to establish a jaw position based on a harmonious relationship of the three main factors affecting occlusion — the teeth, muscles and joints. The resulting jaw position is called the neuromuscular occlusion.
N-M dentistry takes into considerations that status and function of the muscles that control jaw position, chewing and swallowing. N-M test results give the dentist added insight – that 3rd dimension may very well allow us to improve the final treatment results. Using computerized equipment the dentist can measure and study the pattern of jaw opening and closing through its full range of motion in 3 dimensions. The computer can also document the precise point at which your jaw is being held in relation to upper teeth and can measure the activity of key muscles that control the jaw – both in function and at rest. Rather than relying on your present jaw position as being the best one for you, the dentist can use the additional information to determine if your bite should be left as is, or adjust it to a more optimal position. The NM tests are non-invasive – there are no injections and there is no pain.
Dr. Ghodsi has studied extensively with the top neuromuscular dentists in the world to become an expert in this field. Cosmetic & Laser Dentistry of Las Vegas has invested in Sophisticated computerized EMG (electromyography of the jaw muscle), TMJ sonography, and magnetic jaw tracking equipments to enable us to deliver optimal treatment for patients with lasting results.
Neuromuscular TMD Evaluation
The first goal of neuromuscular dentistry is to find the position of the jaw where the muscles are relaxed and at rest. This is a three dimensional position in space and is often irrespective to the position of the teeth.
We utilize the device J-4 Myo-monitor to relax the muscles. It is a low frequency T.E.N.S. (Transcutaneous Electrical Neural Stimulation) unit. This device delivers a mild electrical impulse to the muscles that move the jaw. The rhythmic pulsing (once every 1.0 to1.5 seconds) relaxes the muscles. In addition to relaxing the muscles, it sets up ideal muscle function by increasing blood flow, flushing out toxins. We often find that after 60 minutes of stimulation, the muscles are in their ideal position.
After relaxing the jaw, we then utilize a number of sophisticated instruments to find the position of the jaw where the jaws, teeth, and muscles operate in harmony. Electromyograph is used to measure the masticatory muscle electrical activity. Muscle activity is measured by recording the amount of electrical activity in individual muscles. At physiologic rest of the jaw, muscles of the head and neck should have minimal activity. Bipolar surface electrodes are placed to eight muscles and real time scans of the muscle activities are taken. The program permits taking electromyography data either at rest or in function. The Eight Channel EMG is used to verify that this new position results in decreased muscle activity.
Recording and monitoring jaw movements during opening and closing are very important in developing proper bite. The Computerized Mandibular Scanning Unit (CMS) utilizes multiple sensors in an extremely light weight (four ounce) spectacle-like array, track the motion of a tiny magnet attached to the lower incisal gingiva with adhesive material.
Temporomandibular Joint (TMJ) is the most important component of the jaw. TMJ needs to be in its most physiologic position for proper function and balance. We utilize an Electrosonograph (ESG) to record and monitor TMJ Vibrations and sounds – simply and non-invasively. A lightweight headset holds highly sensitive vibration transducers over each TM joint, enabling simultaneous, bilateral capture of tissue vibrations emanating from joint sounds. Vibration (sound) data is correlated to vertical dimension of opening and closing, providing clinicians with valuable information to aid in assessing the status of the disk and joint function.
