Common misaligned teeth that require orthodontic treatment in children

Generally speaking, orthodontic correction is required when the following seven common types of dental irregularities occur:

※ Crowded teeth, protruding canine teeth (tiger teeth) and dental arches It cannot match the size of the teeth, and the lack of space causes overlapping and crowding of the teeth. The second molar in the lower jaw is the last to erupt and is pushed toward the lingual side.

※Interdental gaps The dental arch cannot match the size of the teeth. When the teeth are too small and the dental arch is too large, the teeth will be sparsely arranged and have gaps.

※Buck teeth can be divided into dental and skeletal buck teeth. Most of them can be treated with traditional orthodontics. Patients with severe buck teeth need to cooperate with oral surgery to achieve the ideal appearance and bite function.

※In an open bite, the upper and lower front teeth should be able to close together. The normal vertical overlap is 2mm. If the upper and lower front teeth cannot bite together, it is an open bite, which will cause the upper and lower front teeth to be unable to cut food and speak. The air leaks and spits, and the mouth cannot be closed tightly.

※An underbite is also called an opposing bite, that is, the lower front teeth bite outside the upper front teeth, commonly known as overbite. In addition to aesthetic problems, it can also cause functional impairments such as chewing and pronunciation. If the crossbite is caused by bony jaw abnormalities, it often needs to be treated with orthognathic surgery.

※ Teeth are tilted. Long-term tooth defects cause adjacent teeth to tilt or the other side's teeth to grow, making it difficult to make dentures. At this time, it is necessary to use correction methods to straighten the tilted teeth so that the roots of the teeth are well parallel to facilitate Denture reconstruction. ※Abnormal facial and jaw bone development. Improper jaw development will cause facial distortion. It is necessary to combine dentition correction and orthognathic surgery. After the jaw relationship is adjusted to a normal position, the teeth can be arranged in the correct jaw bone to restore beauty and function.
