TMJ, Splint Therapy & Occlusion (Bite)

Dr. Last is committed to helping patients who suffer from TMJ disorders and is excited to provide her patients with the most effective and scientifically based therapies available. As part of her passion for this area of dentistry, she makes this one of her primary focuses in her ongoing continuing education. What is TMJ Disorder? There are two components to TMJ (temporomandibular joint) disorders: problems within the joint itself and problems with surrounding musculature. A patient may have a problem in one or both of these areas at the same time. A grinding or clenching habit usually contributes to the exacerbation of these disorders. When problems develop within the joint they are usually related to the movement of the disc within the joint space. Or, joint problems may be due to trauma or development of a neoplasm (cancer) within the joint space. Issues with musculature are usually related to overworking of the muscles surrounding the joint. Excess activity in these muscles is often related to grinding or clenching. Sometimes, the muscles may be overactive due to discrepancies within a bite that create interferences and muscle pain. Signs and Symptoms of TMJ Chronic headaches, especially headaches located around the temple region or in the forehead Worn-looking teeth Awareness of a grinding or clenching habit Tiredness or soreness in the jaw muscles Popping or clicking noises within the joint itself Treatments for TMJ Disorder There are many different types of treatments available for TMJ disorders, among the most common are splint therapy and occlusal equilibration. Splint Therapy A splint is a dental prosthetic device made of clear acrylic, which is worn over the teeth. There are many types of splints available and each splint has a different purpose. Splints are used to deprogram the chewing muscles and position these muscles in a calm state where they can no longer be overactive. Additionally, splints position the TM joint in the most physiologically correct position. In this position the disc inside the joint has a better chance of resting in an appropriate and comfortable location. Splints take the pressure off of the joints and muscles, which often greatly reduces the signs and symptoms associated with TMJ dysfunction. Splints are also helpful in that they protect the teeth from additional wear, which is common in heavy clenching or grinding habits. Occlusal Equilibration (Complete Bite Adjustment) Occlusal equilibration is a process by which small amounts of enamel are selectively removed from the teeth to allow the bite to close in a more stable and healthy position. Incredibly, sometimes a little selective enamel removal is all that is necessary to help a person become free of TMJ pain. Dr. Last is well-trained in this procedure and will be happy to discuss whether this service may be beneficial in eliminating your TMJ disorder. Often, occlusal equilibration is also indicated before placement of extensive restorative dentistry, like crowns, implants and bridges.
