How is deep coverage of anterior teeth caused, orthodontics, deep coverage of front teeth, teeth

There are several causes of deep coverage of the anterior teeth:

1.Bad habits.

Long-term bad habits such as finger sucking, biting the lower lip and licking the upper front teeth have put long-term pressure on the upper front teeth to push the lips, which is easy to tilt the upper front teeth to the lip, and at the same time, the lower front teeth are inclined and crowded with the tongue, resulting in excessive coverage of the front teeth. It may cause jaw dysplasia.

2.Localized disorders of tooth replacement or tooth eruption.

1) Congenital loss of lower anterior teeth, which is common in clinical error, and the loss of 1 2 lower incisors makes the anterior segment of the lower dental arch smaller, resulting in the retraction of the lower dental arch and the deep coverage of the anterior teeth. The deformity may be exacerbated by secondary lip biting or mouth breathing habits.

2) Premature loss of primary molarsPremature loss of primary molars can lead to a smaller anterior segment of the lower arch and increase the coverage of the anterior teeth.

3) Extra teeth in the maxillary anterior area of the supernumb tooth can make the dental arch larger or cause the labial misalignment of the upper incisor, resulting in excessive deep coverage of the anterior teeth.

4) The abnormal order of tooth eruption of the upper second permanent molars precedes the eruption of the lower second permanent molars, or the eruption of the upper first permanent molars earlier than the lower first permanent molars, or the eruption of the upper second permanent molars before the upper canines, etc., may cause the distal relationship of the molars and make the anterior teeth deeply covered.

3.Far middle ladder.

The upper and lower second deciduous molars have a distal relationship, resulting in deep coverage of the anterior teeth.

4.Mouth breathing.

Nasal respiratory diseases often cause partial obstruction of the nasal passages, and gradually form the habit of breathing with the mouth open. The labial muscles of the patient lose normal pressure on the labial side of the upper anterior teeth due to relaxation, and the buccal muscles on both sides compress the dental arch due to elongation, narrowing it, forming a high arch of the palatine, and the anterior teeth are deeply covered and the maxillary or arch protrusion deformity.

5.Systemic diseases such as rickets or disorders of calcium and phosphorus metabolism.

Weak muscle and ligament tension leads to narrowing of the maxillary arch, protrusion of the upper teeth, and distal malocclusion.

6.Genetic factors.

The deep coverage of the anterior teeth is often accompanied by obvious skeletal deformities, such as overdevelopment of the upper jaw or underdevelopment of the lower jaw.

It is recommended that orthodontics can be considered to improve such a situation.

When clenching a tooth, the lower teeth are completely covered by the upper teeth, or only a small part is exposed, it can be judged as a deep overbit.

Deep coverageBecause the bite is too deep, it will smile when laughing.

It can also affect oral health. Since the upper teeth cover the lower teeth, the front two teeth wear out against each other when eating, which can easily lead to enamel damage and tooth sensitivity.

In addition, if the teeth are deeply closed, the length from the nose to the chin will be shorter than the length of the first two chambers.

If the overbite is severe, the lower teeth bite directly into the medial upper gums, causing periodontal damage, which may cause periodontitis and loose teeth.

It is recommended to go to a regular dental hospital for orthodontics, Xiamen Meilai deep overbite orthodontics, mainly to elevate the tooth occlusion, and reassemble the facial bone position according to the pre-designed ideal facial structure relationship and ratio. After deep overbite adjustment, it can not only improve the aesthetics, but also improve the occlusal relationship of the teeth, which is beneficial to the health of the teeth and periodontal.

Deep overbite is a manifestation of deformity, which means that the front teeth will bite the upper lip gums, and it is easy to cause periodontitis in the front teeth, resulting in a decrease in the occlusion of the teeth. There are many harms to the appearance of deep overbite of teeth, first of all, it affects the aesthetics of the teeth, and it is easy to cause damage to the gums. Xiamen Mei XM Lai said that the occurrence of deep overlap can be corrected in time, and the length of the general correction time needs to be seen according to the severity of each person.

The purpose of wearing a retainer after removing the appliance is to strengthen the stability of the tooth in the new position and prevent the occurrence of ** discomfort.

Also each**, I don't know which case.
