Occlusal splints are worn at night to guide the occlusal movement so that the periodontal damage is minimal. The appliance covers all the maxillary or mandibular teeth, but it is mostly worn in the upper maxilla. Occlusal splints are generally appreciated to prevent tooth wear, injuries and reduce nighttime clenching. Splints should cover the occlusal surfaces of all the teeth. With the use of a splint, there will be some reduction in muscle tone. The appliance that helps manage the consequences of nocturnal bruxism is the flat-planed stabilization splint, also called occlusal bite guard, bruxism appliance, biteplate, or nightguard.
