The orthodontist also needs to consider whether to extract teeth or not to perform orthodontics, so where? I have compiled it for you below. Friends who are interested can take a look.
The following points are not the main reasons for tooth extraction:
1. Crowding of the dentition, patients with severe crowding,
2. The protrusion of teeth, patients whose front teeth are too protruding,
3. The coverage of teeth, that is, the treatment of excessive distance between the upper and lower front teeth.
The situation of tooth extraction for orthodontic treatment
1. Upper central incisor 1/1: The upper central incisor is generally not used as a subtraction object. Unless the tooth has severe trauma, root resorption, bent root, eruption failure and other special circumstances that make it inappropriate to retain it, in addition to relieving the crowding of the front teeth, the lateral incisor on the same side can be moved to the position of the central incisor and filled with porcelain. The prosthetic crowns were restored to replace the central incisors, and the cusps of the ipsilateral canines were ground to replace the lateral incisors.
2. Upper lateral incisor 2/2: If the upper lateral incisor is located on the palatal side away from the dental arch, or when the root of the tooth is resorbed or the tooth with a curved root is difficult to be discharged into the dentition, or when the eruption guidance fails, or due to upper lateral incisor When the canines are completely labially depressed and the roots are obviously mesially inclined, it may be considered to extract the maxillary lateral incisors, move the maxillary canines to the position of the lateral incisors, and grind the cusps to replace the lateral incisors.
3. Canines 3/3: Canines are usually not removed to relieve crowding. Because the canines are located at the corners of the mouth, they play a certain role in maintaining the fullness of the corners of the mouth. The root of the tooth is strong and has a low caries rate. It plays an important role in protecting the occlusal function and should be preserved as much as possible. However, if the canine is completely located on the labial side due to severe crowding, and the root tip is obliquely mesial or the root is mostly resorbed, the root will In cases of bending, failure to guide eruption, etc., canine extraction may also be considered.
4. First bicuspid 4/4: often the first choice for tooth extraction to relieve crowding. This tooth is located in the middle of the front and rear dental arches. It is a tooth that contributes little to chewing function and has little impact on appearance. After extraction, the gap is very convenient to relieve crowding of the front teeth. At the same time, the second bicuspid can form a good adjoining relationship with the canine. , has almost no adverse impact on functionality and aesthetics. Therefore, removing it will not affect chewing, nor will it cause other teeth to loosen.
It still depends on the specific situation of the patient. Not all corrections require tooth extraction. As for the adverse effects on health that many patients are worried about, they can definitely rest assured.
As long as correction is performed in a regular medical institution, tooth extraction is a very mature treatment method and will never cause harm to the patient's oral function and health. Its main purpose is to coordinate the inconsistency between tooth volume and bone volume. , making the treatment results more stable.
The principle of orthodontic treatment
The principle of orthodontic treatment is mainly to use appliances to adjust the nerves between the upper and lower jaws, between the upper and lower teeth, between the teeth and the jaws, and the associated nerves. and the abnormal relationship between muscles, ultimately achieving a stable and beautiful effect of the oral and jaw system.
Tooth extraction correction has become a common method in clinical treatment, and more than 60% of patients require tooth extraction during the correction process. In particular, patients with crowded teeth, facial protrusion, and abnormal bite relationships must undergo correction after tooth extraction to ensure good correction results.
Orthodontic methods for different age groups
Orthodontic treatment is the treatment of malocclusion through orthodontic or surgical methods. Malocclusion refers to the congenital deformity caused by the growth and development of children. Malformations of teeth, jaws, and craniofacial diseases caused by factors or acquired factors, malocclusion, dental caries, and periodontal disease are listed as the three most common oral diseases, with a prevalence rate as high as more than 50% of the population.
Malocclusion manifests as incoordination between the teeth and jaws, the upper and lower dental arches, the upper and lower jaws, the jaws and the craniofacial surface, thus affecting the beauty of the face and the function of the oral cavity. Severe malocclusion Deformities can also cause psychological and mental disorders in some patients, which can have a negative impact on further education, job hunting, and spouse selection. Therefore, it is very necessary to correct the teeth to improve their appearance and restore their normal functions.
Orthodontics is a long-term systematic project
We should pay attention to the health and development of children's teeth from the deciduous teeth stage. Some serious deformities, such as crossbite, need to be paid attention to during the deciduous teeth stage. Get early treatment. When children begin to replace their teeth, they should establish contact with the orthodontist, perform regular check-ups, observe the situation of tooth replacement, and intervene in some bad habits and tooth replacement obstacles that may cause malocclusion.
Some serious skeletal deformities, such as maxillary protrusion, mandibular protrusion, and open jaw, require early correction before puberty to block the development of malocclusion and guide the normal growth of teeth and jaws.
