The present invention relates to an intraoral device for preventing snoring and sleep apnea that can be used while tightly enclosing the ceiling of the mouth to prevent separation during sleep, and adjusting the upper and lower teeth inserted in the upper teeth and lower teeth in accordance with the dentition. . In this invention, in the oral device for preventing snoring and sleep apnea, an upper outer guide, an upper inner guide, and an upper occlusal surface are provided to form an upper tooth fitting portion into which the upper teeth are inserted, so that the upper mouse and lower teeth are inserted into the upper rigid panel. A lower outer guide, a lower inner guide, and a lower occlusal surface are provided to form a lower tooth fitting part to be fitted, including a lower stiffness panel and a lower mouse, which is connected to the upper end of the upper inner guide to closely support the palatal in the mouth. It is a technical idea to include a formed hard palate support, a guide slit formed on the upper occlusal surface and a sliding rod formed on the lower mouse so as to slide along the guide slit in order to connect the upper and lower mice so as to be movable back and forth. Therefore, in the present invention, since the hard palate support closely supports the hard palate in the mouth, the upper mouse is prevented from being separated by the pushing force of the tongue during sleep, and the upper mouse and the lower mouse are combined with the guide slit and the sliding rod. It has a very useful effect that can be moved back and forth and used by adjusting it according to various teeth.본 발명은 입천장을 밀착되게 감싸서 수면 중 분리를 방지하고, 윗니에 끼우는 어퍼마우스와 아랫니에 끼우는 로워마우스를 전후로 조절하여 치열에 따라 조절하면서 사용할 수 있는 코골이 및 수면 무호흡 방지용 구강내 장치에 관한 것이다.이러한 본 발명은, 코골이 및 수면 무호흡 방지용 구강내 장치에 있어서, 윗니가 끼워지는 윗니끼움부를 형성하도록 어퍼 아웃터가이드과 어퍼 이너가이드 및 어퍼교합면이 구비되어 어퍼강성패널이 인서트된 어퍼마우스, 아랫니가 끼워지는 아랫니끼움부를 형성하도록 로워 아웃터가이드와 로워 이너가이드 및 로워교합면이 구비되어 로워강성패널이 인서트된 로워마우스를 포함하되, 상기 어퍼 이너가이드의 상단에 연결되어 입 속 경구개를 밀착되게 받치도록
