The displacement of the teeth in the tooth row or the position of the tooth outside the tooth row is mainly due to a violation of the sequence of teething. What are the most common bias most commonly found in humans?

Teeth can be displaced in the sides, that is, back or forth from the middle line. Also, the teeth can be rotated around the longitudinal axis or located above or below the adjacent teeth. The displacement of teeth often occurs simultaneously in 2-3 directions in relation to the tooth row.

Consequences of a broken tooth improperly can cause radical changes in the position of other teeth, which can provoke a change in bite. As a result, aesthetic and functional impairment arises. At the same time displaced teeth can easily lead to injury of the mucous membrane of the cheeks, tongue, lips, palate, and cause the formation of ulcers or erosions.

The most common displacement of teeth in humans

Mesiodistal displacement of the teeth-the location of the teeth at the rear or ahead of the normal place in the tooth arch. Both side and front teeth can be displaced. The reason for such shifts is the early loss of dairy or permanent teeth that are adjacent to the displaced tooth, or the wrong position of the tooth germ. example:

  • In the absence of lateral incisors there is a distal and very significant deviation of the central incisors;
  • Offset to the middle teeth that are adjacent to the remote central cutter;
  • As a result of an early loss of 5 milk teeth, the mesial movement of 6 teeth.

Distal biases are the most frequent anomalies in the displacement of teeth in humans.

Oral inclination (tongue or palatine bias)

Oral or oral tilt is the displacement or inclination of the teeth towards the sky or the tongue. With the inclination of the dental root is located in the alveolar sprout and only the crown part is inclined orally. With such a displacement, the teeth are located outside the tooth arch. Very often the oral displacement of the teeth may be combined with other types of dental anomalies such as the vestibular position of the iliac, distal and deep bite, tooth rotation along the axis.

Diastema (wide or narrow gap between central incisors)

Such a displacement occurs on the upper jaw much more often than on the lower jaw. As a rule, the causes of diastema are low attachment of the upper lip of the lobe, congenital absence of lateral incisors, the presence of supercomplex teeth, irregular shape and size of the teeth, improper placement of the front teeth.

High teeth position (supraocclusion)

Supra-occlusion - displacement of teeth exclusively in the vertical direction. Supra-occlusion is the high position of the tooth on the upper jaw, which does not reach the correct plane of closure of the dentition. Supra-occlusion of the lower jaw is called protruding beyond the plane of the tooth position.

All these shifts in the teeth are treated and equalized, the main thing - in time to contact a dentist and orthodontist. In this case, a good smile will be guaranteed to you.
