Do you know how important teeth are? According to professional dentists, there are more and more people who want cosmetic surgery, but most of them have facial disfigurement caused by malocclusion, which in the end is actually because their teeth have not grown well. So whether your face is beautiful or not, the key still depends on the teeth! Therefore, there is such a word: orthodontic tooth extraction, but mentioning orthodontic tooth extraction, I believe that many people have a capital “NO” in their hearts, people do not want to lose their own teeth, why should orthodontic tooth extraction? In the process of orthodontic treatment, tooth extraction orthodontic methods are very common, but not blind. Whether orthodontic treatment requires tooth extraction, usually need to take into account a variety of factors, such as dental alignment, upper and lower jaws, face, and according to the dental model and the data provided by the X-ray to analyze and judge, can not be generalized. The orthodontic treatment can use the gap created after tooth extraction to realign the crowded teeth, thus coordinating the relationship between tooth and bone volume and reducing the recurrence of malformation. 2.Protruding teeth If the front teeth are too protruding, a certain number of teeth need to be extracted to obtain a gap, so as to achieve the purpose of internalizing the front teeth and moving the back teeth forward to relieve the facial protrusion, thus making the customer’s facial side appearance more beautiful. 3.Orthodontic bite relationship abnormalities The bite relationship of upper and lower teeth can be adjusted by orthodontic treatment through tooth extraction. The extraction gap adjusts the occlusal relationship of the back teeth so that the cusps and sockets of the back teeth are interlaced and the occlusal contact area is maximized to achieve the best chewing efficiency. Extraction is not simply a matter of “giving up the original”, but of making the teeth more natural in terms of functionality and beauty after orthodontic treatment.
