Intrabuccal device includes two shells (2, 3) made of thermoformed plastic material, the first of which respectively covers the superior arch, and the second of which covers the inferior arch of the oral cavity. This device is provided with (rings and arms) (4a, 4b, 13a, 13b) that act on the said shells (2, 3) and can generate a mandibular propulsion force oriented in the direction of the mandibular propulsion and in the posteroanterior sense, so as to keep a shift of the mandible to the front of the maxilla, while allowing lateral movements.

1. An intrabuccal device for insertion into a patient's oral cavity to control the position of the patient's mandible with respect to the patient's maxilla, which oral cavity has a superior arch, an inferior arch premolars and an occlusal plane, the device comprising:two shells made of thermoformed plastic material, the first of which covers the superior arch, and the second of which covers the interior arch, the device including an actuator acting on the shells for generating a mandibular propulsive force oriented in the direction of mandibular propulsion in a posterior-anterior sense and allowing a mandibular retrusion force, wherein the actuator comprises: on one of the two shells, adjacent to the premolars in the oral cavity, a pair of rings that project beyond the occlusal plane, and on the other shell, a pair of free arms that project beyond the occlusal plane and are parallel thereto, the two arms being fastened on an anterior lingual face of the shell and being oriented in the general direction of the occlusion line, the arms engaging and sliding in the rings to keep a shift of the mandible to the front of the maxilla while allowing lateral movements.
