It refers to the patients whose incisal margin of the upper anterior teeth is more than 1 / 3 of the length of the crown of the lower anterior teeth, or the patients whose lower anterior teeth occlude more than 1 / 3 of the lingual side of the upper anterior teeth. There are many factors causing this, which are not only related to heredity, but also closely related to incorrect tooth habits.

Secondly, the upper central incisors are vertical or introverted, the incisors on both sides are inclined, or the upper incisors are introverted while the canines are inclined, or all the upper anterior teeth are introverted, and the coverage of the anterior teeth is less than 3 mm, sometimes 0-1 mm; or the upper and lower anterior teeth are crowded and introverted, showing severe occlusion, which can bite the lingual or labial gingival tissue of the upper and lower anterior teeth, causing acute and chronic periodontitis, resulting in alveolar bone absorption, tooth loosening, etc The posterior teeth were neutral or distally related, and the lower arch was shortened.

The compensation curve of the upper arch is opposite to the sagittal curve of the lower arch in the final and deep overbite. The mandibular forward extension and lateral movement are blocked, and the mandible can only perform the action of tension and closure. Functional mandibular retrusion, normal or excessive tension of labial and masticatory muscles, and the muscle potentials of some ICP clenching are large. The shape of the facial jaw is well developed, and it is generally in the aspect. The height of the lower 1 / 3 is short, the mandibular angle is prominent, and the mandibular plane angle is low angle. The facial shape of deep overbite is lower lip valgus, forming horizontal deep chin wrinkles, chin protruding forward, nasal alar rising outward, upper lip shortening.
