FIELD: medicine.SUBSTANCE: training device is made of a polymer material and shaped as a tray covering the dental arch and the vestibular clivus on the upper jaw, and partially the dental arch on the lower jaw. The training device covers the vestibular clivus of the upper jaw at 2 mm from the gingival groove, as well as the mandibular tuberosity and teeth cutting edges. The training device covers the dental arches of the upper and lower jaws to second molars, while a distal border of the palatal portion of the training device is attached within the area from a line drawn between mesial surfaces of the first pre-molars of the upper jaw, to a line drawn between distal surfaces of the first molars of the upper jaw. The palatal portion of the training device represents a partition mounted at the same level with an occlusion surface of the training device covering the dental arches; between the partition and the hard palate, there is an empty space, wherein air can penetrate when the patient breathes. The training device has the vestibular surface 2-3.5 mm thick and the occlusion surface 3-5 mm thick.EFFECT: training device does not block the lower jaw motions and can be used for workouts aiming at increasing the sportsmen's functional qualification by means of resistive-respiratory loads, more complete adaptation to protective trays.2 cl, 4 dwg |
