The device has a bite raiser that is connected to the maxilla (10) and/or mandible (11) and covers the occlusal surface of the masticatory teeth (13). A splint (12) adapted to tooth crowns is provided for the bite raiser, and has the masticatory teeth with an occlusal elevation (14) for reducing the size of the masticatory surface (15). The occlusal elevation overlies the cusp tips (17) of a masticatory tooth in order to link the bite elevation (20) to the covered masticatory tooth.
