Correction device membrane and correction device

Abstract

The invention discloses a correction device membrane and a correction device. The correction device membrane comprises a first soft polymer layer, a hard polymer layer and a second soft polymer layerwhich are combined from top to bottom in sequence; the thicknesses of the first soft polymer layer and the second soft polymer layer are smaller than the thickness of the hard polymer layer; for the hard polymer layer, the yield elongation is larger than 4%, the breaking elongation is larger than 70%, the tensile modulus is larger than 150,000 psi, and the flexural modulus is larger than 150,000 psi; for the first soft polymer layer and the second soft polymer layer, the hardness is 60 A-85 D, the ultimate tensile strength is larger than 5,000 psi, the breaking elongation is 180-220%, and theflexural modulus is larger than 35,000 psi. Through structural design of the correction device membrane, the orthodontics membrane generates more continuous, stable and effective correction force, teeth of a patient can be moved to the expected positions, the balance, stability and attractiveness of the mouth-jaw system are achieved, and the satisfied orthodontics effect is achieved.

Description

technical field [0001] The invention relates to the technical field of orthodontics, in particular to an orthodontic diaphragm and an orthodontic appliance. Background technique [0002] The goal of orthodontics is to move a patient's teeth into a position that optimizes function and / or aesthetics. Traditional aligners, devices such as brackets, are applied by the treating physician to the patient's teeth with an archwire that exerts a constant force on the patient and gradually urges them closer to the desired position of the physician, as the treatment progresses. Over time, a series of shifting adjustments eventually move the tooth into its intended position. However, traditional orthodontics use brackets and arch wires, which affect the appearance, and the brackets are prone to food residues, bacteria in the oral cavity, and the brackets and arch wires irritate the mucosa and soft tissues, causing discomfort or soft tissue inflammation, and dental caries. The invention...

Problems solved by technology

[0004] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a corrector diaphragm and a corrector, thereby overcoming the existing invisible aligner, the force exerted by the orthodontic diaphragm used in the correction process cannot Sustained and stable, the patient's teeth cannot be moved to the desired position, and it is difficult to obtain a satisfactory orthodontic effect
