Today's circle of friends was supervised by CCTV in an interview and report by Professor Zhou Yanheng (Chairman of China Orthodontics Special Committee and Director of Orthodontics Department of Peking University Stomatological Hospital).
In the video, Director Zhou emphasized the importance of early childhood correction. So, what is professional early childhood correction? Under what circumstances is early childhood correction necessary?
What is early childhood correction?
Early childhood correction refers to the prevention of dental and jaw deformities and deformities (that is, the cause of dental jaw deformities) that have been shown during the early growth and development stages of children (usually before or during the peak period of adolescent growth). , Block, correct and guide treatment. It mainly includes the following three aspects: 1. Early prevention, 2. Early blocking, 3. Early growth control
Early prevention: refers to the timely detection and removal of systemic and local adverse factors that affect the normal growth and development of teeth, alveolar bone, and jawbone, or to correct minor abnormalities to make the dental and maxillofacial surfaces grow harmoniously. Removing the influencing factors can prevent the occurrence of malocclusion.
Early block: refers to the teeth, dentition, occlusal relationship, and bone development abnormalities caused by innate or acquired factors caused by congenital or acquired factors in breasts and dentitions. Simple methods are used to prevent them. The process of malformation development allows it to adjust itself to establish a normal occlusal relationship. In layman's terms, if the malocclusion of the jaw is occurring, the orthodontist will take some measures to stop the process from happening, so as to avoid adverse consequences.
Early growth control: Early growth control refers to the use of occlusal growth guidance and orthopedic treatment at the peak of growth and development for children with severe mandibular abnormalities and abnormal tendencies during the growth phase. The growth of the jawbone changes its growth direction, spatial position and proportional relationship to guide the normal growth of the craniofacial surface.
Let's look at a set of photos
Early childhood growth, due to children's bad habits, prone to dental problems such as tooth irregularities, deep overlap, tooth decay and so on.
At present, the related knowledge about malocclusion in China has not been achieved. Most parents still think that to perform orthodontics must wait until the replacement of permanent teeth of 12-year-old children is completed. However, this is actually not accurate.
5 to 12 years old is a period of rapid growth and development of children's teeth. Children's hormones are strong during sleep. Under the action of growth hormone, children's maxillofacial and teeth develop rapidly.
The study found that children's maxillofacial growth and development completed 60% at 4 years old, 70% at 7 years old, and 90% at 12 years old.
Therefore, orthodontics at the age of 5 to 12 can achieve comfortable orthodontics and allow teeth to grow in the correct physiological direction.
Regarding the golden age of children's orthodontics, Professor Ge Lihong, the director of Pediatric Stomatology at Peking University School of Stomatology, conducted an in-depth analysis from a professional perspective. This talk is more detailed.
As Professor Ge Lihong said, teeth are like small tree saplings. The smaller the correction, the smaller the force on the teeth, the better the correction effect.
The American Orthodontics Association recommends that children have an orthodontic examination no later than 7 years old.
The earlier and shorter the treatment, the less costly it is.
It is also better to correct the misalignment of the upper and lower teeth that cannot be properly engaged as soon as possible.
Which tooth irregularities need early correction
Tooth irregularity refers to the problems of uneven tooth arrangement, abnormal upper and lower dental arch and jaw relationship, abnormal size and position of the jaw, and facial deformity caused by congenital genetic factors or acquired environmental factors during the growth and development of children. There are several situations that need attention.
Deep coverage (cavities)
The anterior maxillary teeth protrude abnormally. In severe cases, it is what we usually call cavities.
The upper teeth cover the lower teeth too much. In severe cases, they can even bite into the lower teeth gums.
The lower teeth envelop the upper teeth, which can cause a crescent face and affect the appearance of the face.
When the teeth are occluded or protruded, the upper and lower teeth cannot touch in a vertical direction.
Tooth volume is larger than bone mass. Insufficient arrangement of teeth causes overlapping and crowded conditions.
Early orthodontics is the consensus of the orthodontics community
In the past, many parents thought that the orthodontics should be done after the tooth replacement (usually after the age of 12). Now there are parents who have received the message: "Muscle function training" in advance, and no further correction is needed. If you listen too much, your parents will be in circles. When is the best time to start correcting?
The answer is the golden age of orthodontics at the age of 5-12 years. During this period, pediatric orthodontics has the following advantages:
1. Make better use of your growth potential before your child's bones mature;
2. Reduce the probability of tooth extraction and orthognathic surgery;
3. Early intervention, low cost;
4. Control abnormalities in development in time to avoid complex situations;
5. Reduce the difficulty of second-stage treatment, the effect is better and stable;
6. Reduce the probability of relapse.
So, how to correct it?
The traditional orthodontist's arsenal is equipped with functional braces (metal bracket, self ligating bracket), fast or slow expanders, anterior maxillary traction and other braces. Each weapon has its best indications, which can solve different developmental deformity problems.
