The invention discloses a hydrogel-coated tooth invisible appliance and a preparation method thereof. By combining nanocellulose/ZnO-CPP-ACP hydrogel and TPU, an inner layer with ZnO-CPP-ACP calcium is formed. TPU modified invisible appliance with phosphorus ion pool coating. The dental invisible appliance can inhibit Streptococcus mutans for a long time by slowly releasing CPP-ACP, and can reduce the incidence of demineralization on the tooth surface during the invisible orthodontic treatment, reverse the white spots on the tooth surface, and achieve long-term effective prevention or inhibition of caries, Protects tooth enamel. The tooth invisible appliance has broad clinical application prospects. |
