A fabricated appliance, usually made from laboratory-processed acrylic resin, designed to cover the occlusal tooth surfaces and modify the occlusal contacts with the opposing dentition. The occlusal surface of the splint is flat without indentations so that the mandible is not guided into any predetermined position. An occlusal splint can have many functions, including to prevent tooth surface loss, to manage mandibular dysfunction, to create space to restore worn anterior teeth, to provide pre-restorative stabilization, and to protect the teeth and new restorations from destructive parafunction.
