<p>The mouthpiece-type orthodontic device of the present invention is configured from: a base (1) that is sandwiched between the rows of teeth (61, 71) of an upper jaw (6) and a lower jaw (7) and that is U-shaped in a planar view; an upper jaw-side outer peripheral wall (2) that protrudes upward from the outer peripheral edge of the base (1) and comes into contact with the upper lip (62) from the inner side thereof; a lower jaw-side outer peripheral wall (3) that protrudes downward from the outer peripheral edge of the base (1), comes into contact with the lower lip (72) from the inner side thereof, and comes into contact with the front teeth section (711) of the lower jaw (7) from the outer side thereof; and an upper jaw-side inner peripheral wall (4) that protrudes upward from the inner peripheral edge of the base (1) and comes into contact with the front teeth section (611) of the upper jaw (6) from the inner side thereof. The inner peripheral surface of the upper jaw-side outer peripheral wall (2) and the outer peripheral surface of the upper jaw-side inner peripheral wall (4) are spaced farther apart than the thickness of the row of teeth (61) of the upper jaw (6). As a result, mandibular prognathism is eliminated or reduced even during the permanent dentition period.</p> |
