In the second case, in the case of deep overbite and overbite of maxillary and mandibular dentition, it is necessary to raise the posterior teeth to open the occlusion and correct the problem of overbite and overbite. The third situation is that some locked patients need to raise their posterior teeth, so that they can be pulled between their jaws without occlusal contact. When the teeth have established a normal occlusal relationship, we will polish the occlusal pad, so it will take about three to six months.
Orthodontic treatment
Orthodontic treatment is mainly to adjust the coordination of maxillofacial bones, teeth, nerves and muscles through various orthodontic devices, that is, to adjust the abnormal relationship between upper and lower jaws, between upper and lower teeth, between teeth and jaws, and between nerves and muscles connecting them, and its ultimate goal is to realize the balance, stability and beauty of oral and maxillofacial system.
The correction of malocclusion mainly depends on wearing an appliance inside or outside the mouth and applying appropriate "biological force" to the teeth, alveolar bone and jaw to make them produce physiological movements, thus correcting malocclusion.
Some malocclusion needs early treatment (3 ~ 6 years old), such as malocclusion caused by bad habits such as biting lips and sucking fingers, in order to avoid adverse effects on maxillofacial region during growth and development. The rest of the malocclusion should be examined by an orthodontist when the permanent teeth begin to erupt (8 ~ 10 years old).
Because at this time, we can observe the eruption process of children's permanent teeth early and regularly, and find and solve problems in time. The best age for most orthodontic treatments is 12- 16 years old. Some orthodontists call this age the "golden age" for orthodontic treatment.
