Orthodontics (MBT straight wire arch)

In the process of dental correction, the small metal piece attached to the tooth - we call it the bracket, is essential, and it is this small bracket that becomes the decisive force of various correction techniques. The alignment direction is determined by the bracket. The traditional brackets are made of square wire bow technology. It must be manually adjusted by the doctor to adjust the bracket angle. It takes a long time and causes a lot of inconvenience to the patient. Because the doctor manually adjusts the bracket angle, the orthodontic effect cannot be fully guaranteed. Treating diseases: crowded with teeth Indication Malformations of the teeth, jaws, and craniofacial caused by congenital factors or acquired factors, malocclusion and dental caries, periodontal disease. Contraindications Older, combined with severe heart, liver, kidney and other diseases and difficult to tolerate surgery. Preoperative preparation 1. Bite the teeth: (that is, take the model) for the diagnosis and design of the doctor's right and wrong, and in the subsequent treatment process. 2, photography: Before the doctor, the doctor should routinely give the patient a photo of the face and occlusion, and leave it to be compared with the end of the treatment. 3, X-ray examination: each patient routinely photographed the lateral side of the skull and the full-face curved tomogram. 4, develop a treatment plan: doctors based on models, photos and X-ray films, after measurement, calculation, diagnosis of the type of mismatch. And develop a detailed treatment plan. 5. The doctor then explains the treatment plan to the patient and the patient's family and solicits the opinions of the patient and the family. After the treatment plan is determined, the patient or patient's family member signs the consent form. Surgical procedure 1, filming Take X-ray teeth and head bone photos. The purpose is to see your teeth and bones in the direction of development. In order to facilitate the development of accurate correction methods in the future, use a quick-set glue to put on your teeth, take a bit of 1-2 minutes to remove, and become a model of your teeth. Spare, also for the convenience of later correction and photo taking. The doctor will take photos of the teeth at various angles between corrections. 2, tooth extraction According to the plan made by the doctor, the teeth are extracted in batches. The average person needs to pull about 4 teeth, some special ones, such as wisdom teeth, and too many teeth are also pulled out about 8 times. If there is any tooth decay between the two, it will be repaired first. If there is a dental calculus, the tooth will be washed first. 3, the teeth Some of the teeth are taken at the same time as the teeth are extracted, while others are carried out after the tooth extraction. It is usually about 1 week between the upper and lower teeth. The purpose is to remove the teeth from the gap, so that the rim of the fixed braces can be placed while wearing the braces. 4, upper braces After the tooth is finished, you can directly apply the 3M braces. Your dental assistant or orthodontist will dry your teeth and "etch" them. Etching can treat the surface of your teeth to add bonding material to secure the braces. Then tie the braces to your teeth. The high intensity plasma light then quickly hits the surface of the mouthpiece to complete the bond. The archwire is ligated to the braces. complication 1. The teeth become loose: under normal conditions, each tooth has a certain physiological motility so as to buffer the chewing pressure and prevent the teeth from being traumatized. When doing orthodontic treatment, the tooth looseness increases, which is a normal reaction. However, the side effects of this orthodontics are recoverable. The alveolar bone and periodontal ligament reconstruction are required for the tooth to move, mainly because the tooth is fixed in the alveolar bone by the periodontal ligament, so that the tooth becomes loose. However, after the orthodontic treatment stops moving to the normal position, the teeth can be stabilized by the reattachment of the periodontal membrane by their own repairing ability, and permanent damage does not occur. Therefore, if the tooth looseness is found to be too large in the clinic, the force should be suspended and the force should be continued after a period of recovery. 2, the impact on the pulp: in the early treatment of orthodontics, a mild, temporary inflammatory reaction in the pulp, showing that the patient has pain or discomfort in the first few days of the home, but the experiment proves that this The impact is not clinically significant. This is also one of the side effects of orthodontics, but it is temporary.
