The dentition of the teeth is the mutual arrangement of the tooth rows when the jaws are fully interlocked.

The formation of the dento-mandibular system begins during intrauterine development. By week 11, the fetus has the jaw bands defined. Almost all babies are born with an incorrect bite. The lower jaw is shifted backward. Dentists call this phenomenon retrognathia. When a baby actively sucks, the muscles are exercised. By 6-8 months of breastfeeding, and a little later, with artificial feeding, the lower jaw takes the correct position. For artificially fed babies, it is necessary to monitor the position of the body, the opening in the nipple. If the formula does not flow from the bottle, you have to make an effort to get it, the child's tongue and jaw muscles get enough load and bite anomalies can be avoided.

Stages of bite formation

The first stage is completed by the time the teeth erupt. It is then formed:

Tooth misalignment is a change in the position of the teeth, after the tooth rows have finished forming, as a result of disease or injury. When teeth erupt, they also change location. This is called a primary relocation. All other cases are secondary movements.

Teeth can change position in a variety of directions, the most common types of movement are as follows:

vertical (unilateral or bilateral); distal - the tooth moves backwards; mesial - the tooth moves forward; tilts; rotation around the axis; combined. Why teeth shift

The most common cause is a violation of the integrity of the tooth row. As a result, the antagonist teeth cease to participate in the chewing process, and the load on the other (working) teeth increases. Tooth contact (occlusion) is compromised and becomes traumatic, destroying the ligaments and stretching the collagen fibers that hold the tooth in place. A tooth that has no contact when the jaws are clamped togeth…
