Problems solved by technology

[0003] At present, fluoride is the main method to prevent tooth enamel demineralization, but the effect of fluoride is limited, and local application of fluoride is also prone to side effects
Therefore, there is currently no good treatment for enamel demineralization in the orthodontic process.

experiment example 1

[0029] Experimental example 1: Effect of the self-etching orthodontic sealant MSEA of the present invention on the shear bond strength of brackets

[0030] In this experimental example, an experimental study is carried out on isolated premolars to determine whether the self-etching orthodontic sealant MSEA of the present invention will affect the bonding strength of the bracket.

[0031] Specimens: 100 complete premolars extracted due to orthodontics were selected and randomly divided into 5 groups with 20 teeth in each group.

[0032] Choose metal premolar brackets (OPK-A, Tomy, Japan), the area of ​​the bracket floor is 9.94mm 2 .

[0033] grouping:

[0034] 1. Traditional phosphoric acid control group: 37% phosphoric acid (phosphoric acid);

[0035] 2. Self-etching control group: AEO control;

[0036] 3. Anti-protein adhesion group: AEO+7.5%MPC, abbreviation: 7.5%MPC;

[0037] 4. Antibacterial group: AEO+5% DMAHDM, referred to as: 5% DMAHDM;

experiment example 2

[0045] Experimental Example 2: Effect of the self-etching orthodontic sealant MSEA of the present invention on the long-term stability of the bracket shear bond strength after being used in the oral environment

[0046] Fixed aligners generally need to be worn in the patient's mouth for about 2 years, and the oral environment is very complex, including changes in temperature and humidity, which will affect the bonding strength of the adhesive, resulting in the bracket falling off and affecting the treatment effect. Therefore, an ideal orthodontic adhesive should still have durable bonding strength under the influence of the oral environment, so as to meet clinical requirements. This experimental example simulates the influence of the oral environment on the bonding strength of the bracket through artificial saliva soaking and cold and hot cycle experiments, so as to judge the effect of using the MSEA of the present invention on the long-term stability of the bonding strength of...

[0060] Experimental example 3: Anti-protein adhesion performance of the self-etching orthodontic sealant MSEA of the present invention

[0061] In this example, the anti-protein ability of the self-etching orthodontic sealant MSEA of the present invention was tested.

[0062] grouping:

[0063] 1. Self-etching control group: AEO control;

[0064] 2. Anti-protein adhesion group: AEO+7.5%MPC, abbreviation: 7.5%MPC;

[0065] 3. Antibacterial group: AEO+5% DMAHDM, referred to as: 5% DMAHDM;

[0066] 4. Mixed group (ie MSEA group): AEO+7.5%MPC+5%DMAHDM.

[0067] Specimen and grouping: Apply the cover of 96-well plate, 1-4 groups are respectively applied to the bottom of the cover groove, pressed with celluloid strips to form a smooth surface, and then cured with visible light for 20 seconds, finally forming a diameter of 8mm, thickness 0.5mm circular test piece. Immerse the test piece in distilled water and stir for 1 h to remove any uncured monomer. All test pieces were drie...

Abstract

The invention discloses a self-etching orthodontic sealing agent and application thereof. The self-etching orthodontic sealing agent is obtained by mixing commercially available self-etching adhesive AEO, methacryloyloxyethyl phosphorylcholine (MPC) and DMAHDM, has an effect for resisting proteins and bacteria, is used for the orthodontic splicing, can prevent the formation and accumulation of dental plaque, and can prevent the demineralization of tooth enamel in the orthodontic treatment.

Description

technical field [0001] The invention belongs to the technical field of orthodontics, and in particular relates to a self-etching orthodontic sealant and its application. Background technique [0002] The orthodontic treatment cycle is often as long as two years, and the structure of the bracket itself is complex, which easily causes the accumulation of food residues and hinders oral cleaning; and patients, especially young patients, often do not pay enough attention to oral hygiene, brushing is not clean and thorough, and food residues accumulate for a long time Attaches to the tooth surface, leading to demineralization of tooth enamel. Moreover, before the traditional bonded orthodontic brackets, it is necessary to acid-etch the surface of the teeth to increase the bonding strength of the brackets. But the traditional acid-etching bonding method has adverse effects on tooth enamel. Studies have shown that conventional 37% phosphoric acid etching removed about 3-10 μm of s...
