Categories of orofacial malformations in adolescents

1. Crossbite

Tooth crossbite is a term for teeth that are not aligned up and down. In layman's terms, it means that the teeth are not straight, which is often referred to as "the earth is covered with the sky".

Causing factors: The crossbite of deciduous teeth has dental factors, which may be caused by local obstacles in the process of tooth eruption and replacement, such as insufficient wear of deciduous canines, premature loss of deciduous front teeth and other factors. Some bad habits may also cause "endless", such as long-term thumb sucking and upper lip biting.

2. Hemignathia

Hemignathia refers to a type of complex deformity with imbalanced lateral relationship between the upper and lower jaws, inconsistent dental midlines, and chin deviation as the main clinical features. It is A very common type of jaw deformity.

Causes: It can be divided into two major categories: congenital and acquired. The possibility of acquired influence includes tooth decay or loss, etc., and long-term use of the other side to eat, resulting in asymmetrical facial shape. Early detection and early treatment can prevent children from the risk of surgery when they grow up.

3. Severe buck teeth

Dontognathic deformity refers to the deformity of the teeth, jaws, and skull caused by congenital genetic factors or acquired environmental factors during the growth and development of children. Facial deformity.

Causes: The cause and pathogenesis of "bump teeth" have not yet been elucidated, and there may be congenital genetic factors and acquired bad habits. The disease has obvious racial characteristics and familial aggregation tendency; but acquired bad habits, such as mouth breathing, tongue thrusting, lower lip biting and adult sucking habits, may also be the cause of the disease.

4. Mandibular retrusion

Mandibular retrusion is a mandibular recession caused by underdevelopment of the mandible or congenital lack of lower front teeth and insufficiency of the lateral pterygoid muscle. Malocclusion. Adolescents with retrognathic jaws can receive early intervention to avoid the need for orthognathic or plastic surgery later in life.

Causes: Congenital developmental disorders: For example, first, in patients with bichiax syndrome, the mandible is bilateral or unilateral, the ramus and body of the mandible are also affected at the same time, and sometimes the hearing bones also develop. Unfavorable; some mandibular retrusion deformities have obvious family history.

5. Dental crowding

Dental crowding is the most common malocclusion. Crowding can be seen in 60% to 70% of patients with malocclusion. It can manifest as crowding, misalignment, and misalignment of teeth; the incidence of dental caries and periodontal disease in crowded teeth is higher than that of teeth in a normal arrangement. In severe cases, it can cause difficulty in closing the lips, resulting in open lips and exposed teeth.

Causing factors: Failure during the replacement period is a common cause of dental crowding. For example, due to early loss of deciduous teeth, adjacent teeth move forward to occupy the missing tooth space, resulting in insufficient space for the eruption of permanent teeth and misalignment. In addition, if the deciduous teeth are retained, it may cause the permanent teeth to erupt out of position.

6. Bad habits

Bad oral habits such as mouth breathing, thumb sucking, tongue licking, lip biting, pen biting, finger biting, sleeping habits, etc., can all cause oral cavity problems. Abnormal muscle function and changes in occlusion affect the development of the baby's teeth and jaws, resulting in severe malocclusion, resulting in changes in the child's face shape!

Therefore, once you find that your children have these bad habits, mothers must correct them in time, otherwise dental deformities will be inevitable!
