Abstract

A magnetic-field-adjustable micromagnetic orthodontic accelerator includes a cheek side plate, a tongue side plate and a supporting plate to form a structure of teeth sleeves, cheek side magnets and tongue side magnets are arranged on the cheek side plate and the tongue side plate respectively, the cheek side magnets and the tongue side magnets form a micro magnetic field environment around roots of to-be-moved teeth receiving orthodontic treatment, physiological magnetic field loss caused by traction of the orthodontic accessory is effectively compensated, metabolism and reconstruction of periodontal tissue of the to-be-moved teeth are promoted, and the orthodontic teeth moving process is accelerated.
