If Children Have Crossbite, the Earlier the Treatment, the Better

The anterior crossbite of some children may be genetically related, or may be caused by some bad oral habits, such as finger biting, tooth licking, and chin extension. If children have anterior crossbite, it should be treated in time, and early orthodontic treatment for crossbite can reduce the deformity of children's facial bones.


1. What is the anterior crossbite


The normal occlusal relationship of the anterior teeth is that the upper anterior teeth cover the front of the lower anterior teeth. The opposite phenomenon, that is, the lower anterior teeth are located in front of the upper anterior teeth can be called the "anterior crossbite", which is a disease of oral malocclusion and a common malocclusion in children. It has a serious impact on oral function, facial aesthetics and mental health. What's worse, the symptoms will deteriorate as patients grow up.


2. What is the best treatment time for the anterior crossbite?


"Anterior crossbite" should be treated as soon as possible, and the treatment is generally divided into three stages.

The first stage: For children of 2 to 5 years old with the anterior crossbite, the best period of treatment is 3 to 4 years old. Especially if there are concomitant symptoms of posterior teeth reverse jaw or partial jaw, the treatment should be conducted as soon as possible to prevent the continued development of the reverse jaw. The treatment method at this stage is simple and painless, and the treatment can be completed in 3 to 6 months.


The second stage: For Children of 6 to 12 years old in the period of mixed dentition and those of 8 to 10 years old in the early period of permanent teeth, it is appropriate to receive the treatment, and the best time for treatment should be about 9 years old. However, children who have insufficient development of the upper jaw and facial depression should be treated as soon as possible.


The third stage: After the age of 12, if the reverse jaw is not corrected in time during the mixed dentition, the mild skeletal impact can still be treated with masking treatment; But if the skeletal deformity is serious, more complex appliances are required, which is difficult, costly and time-consuming to be corrected. Besides, the improvement of the face shape is not obvious, and it can even be corrected with orthognathic surgery.


Childhood "anterior crossbite" is often caused by bad habits. In general, after bad habits are overcome, the lower jaw can return to its original position and the reverse jaw can be eliminated. If it cannot be eliminated, the orthodontic treatment for crossbite is required. In general, anterior crossbite can be treated at about 4 years old. If children can cooperate, they should be treated as soon as possible to prevent the continued development of the reverse jaw.


The mixed dentition period and the early stage of permanent teeth (8 to 10 years old) are suitable treatment periods for "anterior crossbite". Children of this age have a relatively high degree of cooperation. For patients who have insufficient development of the upper jaw and facial depression, they should receive the early orthodontic treatment for crossbite as soon as possible. At this time, a special orthopedic appliance should be worn to pull the growth-restricted upper jaw forward to promote the growth and development of the upper jaw, which can achieve a multiplier effect with less effort.


For adult patients who have already developed, the skeletal cause of lighter can be treated with fixed correction; if the skeletal factor is heavier, surgical operation is needed to correct the wrong bone relationship.
