Abstract: An intraoral orthotic which consists of two halves, one in the maxillary arch and one in the mandibular arch. Both of which have wings projecting from them which interlock upon closing of the mouth. Each half can be fixed permanently or designed to be removable by the patient. When each half is in the approximate arch and the mouth is closed, the wings on the two pieces engage in a predetermined position to allow the meniscus to be in a proper therapeutic position and to stabilize the surrounding muscles of mastication.
