#牙修#Take you to learn about orthodontics knowledge

We all know that tooth extraction during orthodontics is to obtain space for teeth to move and crowd out. However, not all orthodontics require tooth extraction. There are several conventional methods-pushing the molars far, expanding the arch and removing the glaze on the adjacent surfaces, which can also provide space for the teeth. With the rapid popularization of invisible orthodontics, the application of glaze removal on the collar surface has become more and more extensive. For invisible orthodontics, enamel removal on the collar surface is a more effective way to obtain the gap. Compared with tooth extraction, it can appropriately reduce the treatment cycle. 1. What is deglazing the adjacent surface? Interproximal reduction (IPR) is one of the methods of orthodontic treatment to obtain gaps and relieve crowding. IPR usually refers to the use of appropriate equipment to remove a certain amount of enamel on the adjacent surface of the tooth to reduce the width of the mesial and distal teeth and provide a certain amount of space for crowded teeth to reduce the possibility of tooth extraction. Adjacent deglazing is also called “slice cutting” or “tooth reduction”. 2. Indications/contraindications for removing glaze on adjacent surfaces. Each person’s tooth shape is different. Adjacent deglazing is suitable for situations where the crown shape is not good and the teeth are not crowded. Mainly speaking, there are several suitable and contraindicated situations: ①For patients with black triangles before/after correction, IPR can be effectively improved; for patients with torsion of anterior teeth, as the teeth are aligned, the torsion is corrected and normal In the establishment of adjacency, black triangles may appear, and IPR can effectively prevent the appearance of such triangle gaps. ②IPR is contraindicated for teeth with wide abutment surfaces. The abutment surface of these teeth is flat and the base is large. The widest part of the crown is on the gingival side (the end close to the gingiva) rather than the occlusal side (the end close to the bite), which is likely to cause food impact and absorption of the alveolar ridge. IPR is contraindicated. ③There is a view that the closer the roots of the adjacent teeth, the narrower the alveolar ridge between the roots will be, which will reduce the blood supply and ultimately lead to the decline of the periodontal tissue’s resistance to bacterial invasion, which is not conducive to periodontal health and detrimental. The glaze gap is completely closed. 3. The correct deglazing of adjacent surfaces is divided into the following steps: ①Choose the right tooth position at the right time and design in advance according to the plan; ②Use professional equipment to implement the deglaze; ③Repair the shape of the tooth after the adjacent surface is deglazed; ④Tooth surface polishing after deglazing the adjacent surface; ⑤Measure the amount of deglaze; ⑥Fluoride treatment. Is it easier to deglaze adjacent surfaces to cavities? Is it more prone to tooth decay after slices? This is one of the issues that everyone is most concerned about. Generally speaking, it is safe to remove the enamel of less than half the thickness of the tooth surface. How thick is the enamel on the tooth surface? Everyone, every tooth is different, and most teeth have enamel thickness between 0.6mm and 3mm. During the orthodontic process, doctors will operate within a safe range: In order to ensure the safety of clinical operations, anterior teeth and premolars are routinely selected for IPR. Related studies have reported that the enamel after glaze removal is stronger than the original enamel for caries resistance. Comparative experiments show that the removal of fully mineralized enamel on the surface will enhance the potential for remineralization (acid resistance) of the reduced surface enamel. The sliced ​​surface is not more susceptible to caries, and after 9 months, the natural remineralization process of the sliced ​​surface is completed. After finishing the deglaze, the deglaze surface will be polished and fluorine coated. Therefore, it is safe to remove the glaze on the adjacent side of the standard, so there is no need to worry about tooth decay. There are also several questions that people often ask about the deglazing of the adjacent surface: 1. Do you need to use anesthetic to remove the glaze of the adjacent surface? Because the work of removing glaze is limited to the outer layer of enamel, there is no nerve distribution in this layer, so it does not cause pain and does not require anesthetics. 2. Will the adjacent surface bleed after removing the glaze? During the deglazing process, the gingival papilla will be protected, and there is generally no bleeding. If the gums are swollen, it is recommended to perform the operation after the gum inflammation subsides. In a few cases, the edge of the gingival papilla may be touched, and there will be slight bleeding; no matter whether the bleeding is or not, there is generally no pain. 3. Oral care after removing the glaze on the adjacent side? Develop good oral hygiene habits. It is recommended that patients use fluoride dental floss, fluoride toothpaste, fluoride sugar-free chewing gum, or fluoride mouthwash. After removing the glaze on the adjacent surface, the fluorine concentration of the newly formed outermost layer of enamel will increase due to the application of fluoride. The effect of fluorine increases the microhardness of the enamel surface, so the newly formed enamel It may have stronger anti-caries ability than the original enamel. In summary, in the history of orthodontics, the adjacent surface deglazing technology is mature and within a safe range, and patients need not worry about it.
