    • A mandibular advancement device (26) includes a lower part (28), a lower flange (34), an upper part (30) and an upper flange (32). The lower part (28) is releasably attachable to at least a portion of a lower jaw (24). The lower flange (38) has a lower engagement surface extending upwardly from the lower part (28). The upper part (30) is releasably attachable to at least a portion of an upper jaw (22). The upper flange (32) has an upper engagement surface extending downwardly from the upper part (30). The lower flange (34) is connected to the lower part (28) by a lower one way ratchet means configured to only allow uni-directional posterior movement of the lower flange (34) relative to the lower part (28) and/or the upper flange (32) is connected to the upper part (30) by an upper one way ratchet means configured to only allow uni- directional anterior movement of the upper flange (32) relative to the upper part (30). When the lower part (28) and the upper part (30) are fitted to the jaws (22,24) of a patient for use in sleep, the lower engagement surface and the upper engagement surface engage in a manner to cause anterior advancement of the lower jaw (24) from the reflex path of opening.
    • 下颌前进装置(26)包括下部(28),下部凸缘(34),上部(30)和上部凸缘(32)。 下部(28)可拆卸地连接到下颚(24)的至少一部分。 下凸缘(38)具有从下部(28)向上延伸的下接合表面。 上部分(30)可拆卸地连接到上颚(22)的至少一部分上。 上凸缘(32)具有从上部(30)向下延伸的上接合表面。 下部凸缘(34)通过下部单向棘轮装置连接到下部部分(28),下部单向棘轮装置构造成仅允许下部凸缘(34)相对于下部部分(28)的单向后向移动和/或 上部凸缘32通过上部单向棘轮装置连接到上部部分30,所述上部单向棘轮装置构造成仅允许上部凸缘32相对于上部部分30的单向前向移动。 当下部(28)和上部(30)与患者的钳口(22,24)配合用于睡眠时,下接合表面和上接合表面以一种方式接合,以使前部 下颌(24)从开口的反射路径。
