Orthodontic bands are commonly used orthodontic auxiliary tools, mainly used to correct crowded dentition, uneven teeth and other problems. The principle is as follows:
1. Establish goals: The main function of orthodontic bands is to fix teeth and move them to the correct position. Before installing orthodontic bands, the doctor will determine the correction goals and the direction and distance of movement according to the patient's dental condition.
2. Clean teeth: Before installing orthodontic bands, the teeth need to be thoroughly cleaned to ensure that the orthodontic bands can fit firmly on the tooth surface.
3. Install orthodontic bands: The doctor will fix the orthodontic bands on the teeth that need to be corrected and lock them to the back of the teeth with pliers.
4. Apply force: After the orthodontic bands are fixed, the doctor will apply force to the orthodontic bands through auxiliary equipment such as rubber bands or metal wires to gradually move the teeth to the correct position. The specific way and amount of force applied will be adjusted according to the patient's dental condition and treatment plan.
5. Regular adjustment: The force effect of orthodontic bands is not achieved in one go, but requires continuous force and adjustment over a period of time. The doctor will regularly check the patient's teeth and adjust the position and force of the orthodontic bands to ensure the optimal correction effect.
In general, orthodontic bands achieve the effect of tooth correction by applying directional force to change the growth direction and position of teeth. It is simple, effective, and controllable, and is widely recognized in clinical applications.
