In teenager stage, the functional orthopedic treatment can be adopted in time to effectively correct the deformity. However, correction of the bony class III deformity requires sufficient amount of orthopedic force to act for a sufficient period of time.
The commonly used orthopedic devices include mask type front traction, chin bag, frankle III, combined traction, magnetic force double-baffle correction devices and the like, the devices are large in size (such as Frankle III), exposed steel wires (such as combined traction), and mechanical devices placed on the face (such as mask type front traction) are needed, so that the average wearing time is about 12 hours. Particularly, the matching degree is reduced due to the unaesthetic appearance, so that the effective service time of the devices is greatly shortened, and finally, the orthopedic treatment is failed. The magnetic double-baffle appliance does not have an external device, so that a patient can wear the appliance all over the day, and the appliance is an effective way for correcting bone type III deformity, but still has the problem of larger appliance.
Rubber bands, stainless steel wires and stretched muscles are routinely used clinically to create orthopedic forces. Therefore, the prior orthopedic device has the defects of poor aesthetic degree, low comfort level, great influence on voice function, poor controllability of force source and complex manufacturing procedure
In addition, since the patients receiving the orthopedic treatment are teenagers in the rapid physical and psychological development period, the self-consciousness begins to be gradually improved, the attention of the external attractive appearance is gradually enhanced, and the orthopedic device is in accordance with the correction principle in mechanical design and has a positive clinical effect, but in the patients with correction failure, a great part of the orthopedic device is related to the fact that the orthopedic device cannot be used continuously. How to improve the aesthetic degree and the comfort of the correction device and to prolong the effective acting time of the correction force as much as possible are key points for improving the success rate of the correction treatment.

The magnetic blocks are placed on the cheek side and are divided into repulsive force type stress application magnetic blocks and attractive force type stress application magnetic blocks according to different stress application modes. If the magnets are homopolar and opposite, the repulsion type appliance is adopted; if the magnetic blocks are opposite, the magnetic blocks are arranged in a maximum superposition state of one surfaces of the magnetic blocks, which are 3mm and 7mm, of the magnetic blocks for the suction type appliance.
