Abstract: A method of direct fabrication of intraoral devices provides an easy, cost effective way of making a variety of appliances intraorally. The use of a thin layer of unset plastic or thermoplastic material on a flexible tray allows for a customized fit to any palate, directly in the oral cavity. A palatal retainer provides the primary retention for optional functional components to be incorporated. Functional components may include anterior deprogrammers, and full coverage and partial coverage occlusal guards. Use of the palatal retainer provides comfortable, safe retention without the need for excessive facial wrap. The retainer itself can function as a palatal obturator or a healing stent. Fabrication of the appliances could be performed by the end user, health care providers, or anyone skilled in the art.
