1. A magnetic field adjustable micro-magnetic orthodontic accelerator, comprising:
a buccal side plate and a lingual side plate arranged opposite to each other, with buccal side magnets installed in the buccal side plate and lingual side magnets installed in the lingual side plate, wherein the buccal side magnets and the lingual side magnets are positioned opposite to each other in pair, and at least three pair of the buccal side magnets and the lingual side magnets are provided; and
a support plate for connecting the buccal side plate and lingual side plate, to form an accommodating space defined by the support plate, the buccal side plate, and the lingual side plate, giving the magnetic field adjustable micro-magnetic orthodontic accelerator a dental brace structure;
wherein when the magnetic field adjustable micro-magnetic orthodontic accelerator is in use, teeth are placed within the accommodating space, with the buccal side plate and lingual side plate separately positioned on a buccal side and a lingual side of the teeth within the accommodating space, and the buccal side magnets and the lingual side magnets correspondingly positioned to roots of the teeth; and micro-magnetic fields acting on the roots of the teeth are formed between the buccal side magnets and the lingual side magnets in pair;
the buccal side plate and the lingual side plate each comprise an anterior tooth area, a premolar area, and a molar area; the buccal side magnets and the lingual side magnets are arranged opposite to each other in the anterior tooth area, the premolar area, and the molar area;
a number of the buccal side magnets and a number of the lingual side magnets are both 3 to 12;
a micro-magnetic field formed in the anterior tooth area has an intensity of 20-25 mT, a micro-magnetic field formed in the premolar area has an intensity of 15-20 mT, and a micro-magnetic field formed in the molar area has an intensity of 10-15 mT;
the buccal side magnets are detachably installed on the buccal side plate, and the lingual side magnets are detachably installed on the lingual side plate;
the buccal side plate and lingual side plate are provided with tapered grooves; the buccal side magnets and lingual side magnets are inserted into the buccal side plate and the lingual side plate through the tapered grooves, with open edges of the tapered grooves forming locks for the buccal side magnets and lingual side magnets; and
the support plate, the buccal side plate, and the lingual side plate are made of a silicone material, and the silicone material comprises soft silicone or hard silicone.
