Sparse dentition
Introduction
Introduction to dentition sparseness Sparse dentition refers to the gap between teeth. The cause of this phenomenon is generally: the shape of the tooth is small, the shape of the jaw is normal; the tooth is congenitally missing, the shape of the jaw is normal; the shape of the tooth is normal, the jaw is too large; the tooth is not inserted after the tooth extraction, causing displacement of the adjacent tooth in the near and far And a gap is created. Sparse dentition is characterized by small amount of teeth and normal bone mass; or large bone mass, normal tooth volume; or small amount of teeth, large bone mass; or soft tissue factor. The causes of sparse dentition are: the shape of the tooth is small, the shape of the jaw is normal; the tooth is congenitally missing, the shape of the jaw is normal; the shape of the tooth is normal, the jaw is too large; the tooth is not inserted after the tooth extraction, causing the adjacent tooth movement in the near and far Bits create a gap. Sparse dentition is characterized by small amount of teeth and normal bone mass; or large bone mass, normal tooth volume; or small amount of teeth, large bone mass; or soft tissue factor. Bad habits (such as: tooth decay, biting lips, etc.), tooth lip tilt caused by periodontal disease; congenital tooth loss, too small teeth, and genetic factors. basic knowledge Sickness ratio: 0.0001% Susceptible people: no special people Mode of infection: non-infectious Complications: gingivitis periodontitis mental disorder

Dentate sparse cause
Cause
The causes of sparse dentition are: the shape of the tooth is small, the shape of the jaw is normal; the tooth is congenitally missing, the shape of the jaw is normal; the shape of the tooth is normal, the jaw is too large; the tooth is not inserted after the tooth extraction, causing the adjacent tooth movement in the near and far Bits create a gap. Sparse dentition is characterized by small amount of teeth and normal bone mass; or large bone mass, normal tooth volume; or small amount of teeth, large bone mass; or soft tissue factor. Bad habits (such as: tooth decay, biting lips, etc.), tooth lip tilt caused by periodontal disease; congenital tooth loss, too small teeth, and genetic factors.
Prevention
Dentation prevention
The child is around 2.5-6 years old, and the mouth is usually deciduous. During this period, if the number, shape and size of the teeth are normal, and the jaw is developing normally, there are scattered gaps in the dentition, which seems to be sparse. However, this is generally normal, which is conducive to the normal eruption of permanent teeth, clinically generally need correction, if the tooth is small, the shape of the jaw is normal; the tooth is congenitally missing, the shape of the jaw is normal; the shape of the tooth is normal, the jaw is normal. Too large, etc., it often causes sparse dentition, which is a sign of disease, need to be corrected, from 6 to 12 years old, in this age group, intraoral milk permanent teeth exist at the same time, this period is sparsely sparse, Clinically common early deciduous teeth or permanent teeth and the interdental space caused by the abnormal attachment of the labial ligament, as long as the cause of the disease, symptomatic correction, often can get better correction effect.
After the deciduous teeth are completely replaced, after the permanent teeth erupt, the dentition caused by the four types mentioned in the summary is sparse. As long as the early correction is performed, the curative effect is better. If the age of 12-16 years old is missed, the dentition will be corrected. , often the treatment is longer, the effect is not certain, this period can be treated with orthognathic surgery, the dentition is sparse and easy to embed food and damage the periodontal tissue, causing gingivitis, periodontitis, and easy to metamorphosis, severe cases can affect patients The appearance is beautiful, causing mental and mental disorders. The disease is treated differently according to the cause of sparse dentition.
Complication
Dentate sparse complications Complications, gingivitis, periodontitis, mental disorder
Sparse dentition is easy to embed food and damage periodontal tissue, causing gingivitis, periodontitis, and easy to change. In severe cases, it may affect the appearance of the patient and cause mental and mental disorders.
Symptom
Dentist sparse symptoms Common symptoms Incisor spacing widened tooth gaps widened teeth black teeth gap large teeth small and sparse tooth shift
The teeth are normal or too small. The local gap is mostly between the upper middle incisors or the maxillary lateral incisors. The teeth can be arranged neatly. Sometimes the teeth can appear in the near and far direction, the tongue and tongue are dislocated, and so on. Most scattered dentition gaps can appear in the upper jaw, lower jaw or upper and lower jaws. The shape of the face is not affected.
Examine
Sparse inspection
1. Intraoral: There may be upper lip lacing with too low and too wide, sometimes there are many teeth in the upper middle incisor area, the middle incisors are in the middle of the dislocation, and the individual teeth are dislocated. There may also be congenital missing teeth, abnormal tooth shape, and the majority of the teeth are too small or large tongue, and most of the gaps appear in the upper and lower dentition.
2. Model analysis.
3. X-ray film: Take a panoramic picture.
Diagnosis
Dentation diagnosis
diagnosis
There are four types of dentition sparse: one is the small shape of the tooth, the shape of the jaw is normal; the second is the congenital missing tooth, the shape of the jaw is normal; the third is the normal shape of the tooth, the jaw is too large; the fourth is the tooth after the tooth extraction, Causes displacement of adjacent teeth in the near and far, resulting in a gap.
Diagnosis of dentition sparse based on the above four reasons:
1. The amount of bone is larger than the amount of teeth caused by the gap between the teeth.
2. According to the sparse characteristics are divided into:
First, the amount of teeth is small and the bone mass is normal;
Second, the bone mass is large and the tooth volume is normal;
Third, the amount of teeth is small, and the bone mass is large;
Fourth, soft tissue factors.
