Before or during the rapid growth period of teeth. For example, the first permanent molar is the largest.

The eruption period of teeth is a rapid growth period.

First, the stage of deciduous teeth (tooth addition): the occurrence of irregular arrangement of deciduous teeth or inverted dentition (tooth addition)

Close) and open (close) (local teeth can't bite) should be early.

Stage correction, the treatment age is about 3 ~ 6 years old, at this time the child's permanent teeth have not erupted, breast

The root of the tooth is not absorbed and is relatively stable, so it can be carried out by wearing an oral appliance.

The course of treatment is about 6 months. Early treatment is of great significance to the normal development of children's maxillofacial region.

Beneficial. If it is not corrected in time, it may aggravate the deformity in this rapid growth period.

Second, the stage of mixed teeth (adding teeth): it is about 7 ~ 1 1 year, when new permanent teeth are opened.

Initial eruption, rapid tooth growth and unstable occlusion are the frequent periods of tooth deformity. main sourc

Because deciduous teeth fall off prematurely, the length of dental arch is reduced, which leads to the inability to arrange teeth.

Children should be the guardians of the gap; Premature deciduous teeth fall off and close the gap, resulting in insufficient eruption of permanent teeth.

If the teeth are deformed occasionally, the gap should be repaired by appliance; Caused by bad oral habits or hobbies

Tooth deformity, while overcoming and changing bad habits, depends on different situations and different degrees.

We can use movable or fixed appliances from light to heavy, and even cooperate with external plastic forces to correct them.

Orthodontic dentition

Third, the permanent tooth (tooth word plus) period: all the deciduous teeth have been replaced, the second big tooth and the third.

When the big teeth erupt, it is also a rapid growth period, generally around 12 ~ 18 years old, when the teeth are deformed.

The shape diagnosis is clear, the correction speed is fast and the correction effect is stable in this rapid growth period.
