Multilayer orthodontic diaphragm with non-uniform thickness

The invention provides a multilayer orthodontic diaphragm with non-uniform thickness, and relates to the field of tooth orthodontics. The multi-layer orthodontic diaphragm with the non-uniform thickness comprises a multi-layer diaphragm formed by stacking a plurality of single-layer diaphragms, the thickness of the multi-layer diaphragm is non-uniform, and the multi-layer diaphragm is prepared through multi-layer co-extrusion; according to the invention, a plurality of single-layer diaphragms are co-extruded to form a multi-layer diaphragm, so that the problems that the force applied by the existing orthodontic diaphragm cannot be continuous and stable, the teeth of a patient cannot be moved to an expected position, and a satisfactory orthodontic effect is difficult to obtain are solved; and through the non-uniform thickness of the multiple layers of diaphragms, the problems that the thickness of the incisor part in the appliance manufactured by the existing invisible orthodontic diaphragm with uniform thickn
