Abstract

Mouthguards have been fabricated for protecting oral structures from outer forces. The best type of mouthguard is custom-made by dentists with impression technique. But boil-and-bite mouthguards have been also used, because of economic cause or difficulty in impression taking or emergency of the case. Author has found-ed that rigid boil-and-bite mouthguard can provide a suitable retention when it is moulded by dentist. There is a case that rigid boil-and-bite mouthguard was successfully used to provide mouth protection of a patient with severe mouth opening limitation due to autoimmune encephalitis during electroconvulsive therapy. In conclu-sion, the rigid boil-and-bite mouthguard moulded by dentist can be one of the effective treatment options when impression taking is difficult or mouthguard is urgently needed.
