Some friends are concerned about the hidden line orthodontic treatment, so today to talk about the difference between traditional orthodontic treatment and invisible orthodontic treatment: a, traditional orthodontic treatment traditional fixed orthodontic treatment, mostly “wire braces” orthodontic treatment, is in the process of orthodontic treatment with a special adhesive fixed in the tooth surface of a metal or ceramic and other materials made of devices, used to accommodate and fix Orthodontic wire, transferring orthodontic force to the teeth, so as to achieve the purpose of correcting misaligned teeth. 1.Scientific principle The wire braces are made of high quality stainless steel wire, with a diamond-shaped cross-section, mechanically rolled into a spring-shaped thread. The diameter of the wire bushing is larger than the screw hole, when installed, the wire bushing is compressed and tightened, and after the installation is completed, the wire bushing is bounced back to its original state, so that the wire bushing is permanently fixed in the screw hole. Because of its larger diameter, the wire bushing has a larger contact surface and is therefore stronger than the original thread. 2.Installation method Drilling: Remove the damaged threads with a drilling nozzle. Tapping: Tapping with a special tapping tool in the drilled thread. Installation: Use the special installation tool to screw the sheath into the screw hole with light force until the distance between the end of the thread sleeve and the workpiece plane is no more than 1/4 to 1/2 turn. Cross thread cutting: When the workpiece is a through hole, pull up the installation tool and place it across the cross thread, then tap it hard to break the cross thread. In the blind hole, the horizontal line may not be cut. 3.Demolition method The tip part of the demolisher into the hole of the wire bushing, press the handle hard and rotate in the anti-clockwise direction, you can remove the wire bushing. 4, orthodontic cycle ordinary wire orthodontics orthodontic teeth take 1-2 years. 5, precautions (1) in order to correct the effect of the teeth, it is recommended that the aestheticians do not eat bone, hard shell food; (2) during orthodontic treatment, in addition to comply with the instructions of the doctor, but also careful care of the braces on the teeth; (3) less snacks: to reduce the number of snacks and candy, especially chewing gum; (4) regular visits to the hospital to check, replace the wire, wear rubber bands, etc.. Otherwise, the process of orthodontics prolonged, but also can not achieve the desired orthodontic effect; (5) do not eat too sticky food: gnawing or knocking things can not eat, can not eat too sticky food; (6) must keep the mouth clean: use orthodontic special toothbrush, the action should be gentle, slow, 3 ~ 5 minutes each time; (7) timely rinse mouth and brush teeth after meals. Second, invisible orthodontic treatment invisible orthodontic treatment is also called “invisible brackets invisible orthodontics”, using a series of invisible aligners. The invisible orthodontic appliances made of safe elastic transparent polymer material, so that the orthodontic process is completed almost unnoticed by the next person, does not affect daily life and social. At the same time, without the cumbersome bonding brackets and adjusting archwires, the clinical operation is greatly simplified and the whole orthodontic process is time-saving and labor-saving. 1, scientific principle Invisible bracketless orthodontic technology is a high-tech in the field of international orthodontics. This invisible orthodontic technology inherits the traditional malocclusion, is the perfect combination of computer-aided three-dimensional diagnosis, personalized design and digital molding technology. According to the actual situation of each person, through computer-aided three-dimensional diagnosis, design and manufacturing system, with a series of personalized transparent aligners, to complete the orthodontic treatment of dental technology, positioning precision, cleaning and other advantages. 2, how to wear First of all, the doctor should give the patient a thorough examination, take a model for the patient, take X-rays, take intraoral as well as facial photos. After these diagnoses are out, the doctor then design the orthodontic program for the patient, for different patients to measure the “teeth” custom invisible aligners. Secondly, after the patient gets the aligners, the doctor needs to instruct the patient on how to take off and put on the invisible aligners and techniques to avoid pulling on the aligners. As the invisible aligners can be removed and cleaned by themselves, the patient can be all on their own during the wearing period, which is also conducive to maintaining oral hygiene. 3, the cycle process The specific orthodontic cycle, according to the analysis of specific patient conditions, generally in about 1 to 2 years, during the hospital for regular follow-up, if the patient is not convenient to review, for patients in different situations will also have the appropriate solution. 4, attention needs to be paid to the end of the correction, the need to wear in accordance with the doctor’s requirements to complete the retainer, traditional orthodontic treatment is also the same. Although invisible orthodontics is effective and has outstanding advantages, it is not suitable for everyone and is best decided by a clinician after an interview.
