An intraoral discluding appliance for the prevention of trauma and temporomandibular joint syndrome. The device is a small intraoral device that is custom made for each individual patient. The device includes two discluding elements over the cuspid areas known as cuspid pads. The device is inserted in the mouth and retained against the upper or lower anterior teeth. Typically, the device will be retained on the upper anterior teeth but occasionally mandible placement is necessary. As the mouth is closed, the discluding elements contact the opposing cuspids and prevent the posterior teeth from touching. This effectively reduces parafunctional temporal muscle activity, eliminates trauma, and prevents bruxism. The device is removable and may be worn full time, but is typically removed at least during meals and for cleaning. Additionally, the device may be worn only part time, for example it may be used as a bedtime appliance.
