summary

Deep overbite is a kind of complicated dental disease. I had diagnosed it before, and also complicated with other dental diseases. Let's see what deep overbite is.

What is deep overbite

First of all, deep overbite is a kind of malocclusion caused by the vertical development of maxillary and mandibular arch and / or mandible. 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.

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, 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.

Finally: when the age was younger and in the growth period, the functional appliance with plane guide (or inclined guide) and lingual hyperbolic tongue spring of upper anterior teeth was used to stimulate the growth of posterior teeth and inhibit the elongation of anterior teeth, but the lingual inclined anterior teeth should be corrected in advance, and then the length of upper and lower dental arch should be coordinated to correct the relationship between upper and lower teeth and dental arch.

matters needing attention

Deep overbite of teeth affects health, and also easily leads to periodontitis of anterior teeth and facial joint diseases. Therefore, after the illness, it is best to be able to timely treatment, and do a good job in usual nursing measures.
