1. Patients with crowded teeth: The appearance is that teeth come in and out, which is unsightly, difficult to clean, prone to dental caries, easy to form dental calculus and lead to periodontal disease.
2. Anterior malocclusion, also known as "floor covering", shows that the lower teeth bite on the outside of the upper teeth, and some people only have malocclusion; Some people not only have malocclusion of teeth, but also have deformity of facial bones, which is called skeletal malocclusion. It is characterized by hypoplasia-backwardness of maxilla and overdevelopment-protrusion of mandible, which leads to depression in the middle of the face and crescent shape on the side, which affects the appearance and function.
3. Patients with interdental space show that there are many gaps between teeth.
4, deep coverage: also known as "buck teeth", some only show that the upper front teeth are protruding or the lower front teeth are trapped; Some are skeletal deformities. Some of these people's front teeth and upper gums protrude excessively, but their chins shrink behind their upper lips, or they have no chin shape at all.
5, bimaxillary protrusion: or the protrusion of the upper and lower front teeth, leading to lip protrusion, you can forcibly close your lips and expose your lips.
6, locked jaw: patients with teeth without occlusal function.
7. malocclusion of the posterior teeth and jaw locking: it affects the occlusal function of the teeth and may lead to the deviation of the upper and lower jaws for a long time.
8. Patients with deep overbite (too deep occlusion of front teeth): The lower front teeth can't be seen when occluding, and some people are accompanied by skeletal deformity, which shows that the lower half is short. This deformity is easy to bite the upper gum, and it is also easy to cause periodontitis of front teeth and facial joint diseases.
Teeth, in addition to an aesthetic function of appearance, from a professional point of view, its most important function is physiology. In other words, you can eat and chew food. If the teeth are irregular, the most important physiological functions will be affected, which will affect the whole body function. For example, teeth are the first channel of digestion, which means that food enters the digestive system first. Bad teeth are a heavy burden to the whole digestive system. It will not cause any problems in the short term, but it will cause a series of hazards such as indigestion in the long run. This is what teeth do to the whole body system.
