The bracket-free invisible appliance is favored by patients due to the advantages of beauty and comfort, and is more and more applied to orthodontic clinic. However, due to the limitation of materials of the bracket-free invisible orthodontic appliance, there is "hysteresis" when the teeth move, that is, the teeth cannot move to follow the form change of the bracket-free invisible orthodontic appliance, and the preset tooth movement amount cannot be completely realized, so that the orthodontic time is prolonged, and the efficiency is reduced. Especially with respect to elongation and hypotonic movements, studies have shown that anterior teeth have a hypotonic efficiency of only 41.3%.

In clinical practice, the opening of deep occlusions is often difficult during the correction of invisible appliances, and the correction strategies are generally depressing anterior teeth and raising posterior teeth. When the invisible orthodontic appliance is used for depressing the cuspid, the depressing effect is not ideal due to the stout root of the cuspid. And the lower amount of the cuspid does not reach the designed amount, so that the appliance forms a fulcrum at the cuspid, the adjacent teeth cannot be completely in place, the appliance cannot fully wrap the teeth to cause sleeve stripping, and the designed tooth movement is more difficult to realize. Furthermore, when the invisible appliance is used to depress the canine, the premolar is also subject to a reaction force of elongation, and the elongation of the adjacent teeth will unload a portion of the anterior depression.
