Abstract

The invention provides an invisible appliance and a preparation method thereof. The invisible appliance is obtained by introducing a coating material into the surface of an invisible orthodontic substrate through an ultrasonic-assisted technology; the coating material includes fluorine salt, PEG, chitosan Sugar and nano-titanium dioxide, the preparation of coating material adopts PEG-loaded fluorine to obtain stable and long-lasting slow-release fluorine effect, so that it has the property of promoting enamel mineralization; PEG can also improve the dispersion of nano-titanium dioxide particles in suspension, improve the Nano-titanium dioxide has uniform dispersion, good biocompatibility, stable chemical properties, and remarkable bacteriostatic effect. Its combination with chitosan can significantly enhance bacteriostatic properties. The obtained invisible appliance has excellent mechanical properties, long-term bacteriostatic, Features that promote enamel mineralization.

Description

technical field [0001] The invention relates to the technical field of stomatology, in particular, to an invisible appliance and a preparation method thereof. Background technique [0002] Due to the advantages of self-removal and wearing, easy cleaning, aesthetics, comfort, and convenience, invisible appliances have been increasingly favored by patients with malocclusion in recent years. However, with the expansion of the patient group wearing invisible appliances, the complications brought about by invisible appliances have gradually emerged, among which the most common ones are demineralization of tooth enamel and caries. Invisible appliances are in close contact with the tooth surface during wearing, the saliva and air flow rates on the tooth surface are reduced, and the scouring ability of dental plaque is weakened. In addition, the easily formed anaerobic interface changes bacterial metabolism and microecology, which eventually causes Demineralization of tooth enamel....
