Technical Field
The invention belongs to the technical field of dental materials, and particularly relates to an anti-caries invisible orthodontic appliance with an antibacterial coating, and a preparation method and application thereof.
Background
With the continuous improvement of the economic income of people, people have more and more demands on tooth health and whitening, so that the invisible orthodontic appliance is developed very rapidly in China. The invisible orthodontic technology is characterized in that a transparent plastic movable appliance is manufactured on an ideal model and worn on teeth of a patient to facilitate normal growth and development of the dentognathic face and realize correction of the teeth of the patient, generally, the wearing period is 1-2 weeks, the invisible orthodontic appliance is worn for more than 20 hours every day, and the period of orthodontic treatment is longer and is 1-3 years. Because the wearing time of stealthy just abnormal ware is long, make the tooth be in the state of isolated saliva for a long time, the tooth face is difficult clean, and plaque is easy field planting, pile up on the tooth face, forms the biomembrane, and the plaque produces acid simultaneously makes enamel surface pH value reduce, leads to the tooth to demineralize, causes the incidence of disease of enamel chalk spot to rise, and the treatment process is longer, and at the in-process of treatment, need clean stealthy ware of correcting every day to guarantee the cleanliness factor of stealthy ware of correcting.
At present, fluoride is a recognized substance effective in preventing caries. Fluoride inhibits the growth of cariogenic bacteria in the oral cavity, inhibits bacterial acidogenesis, and simultaneously reduces the solubility of enamel surface in the teeth and promotes remineralization of demineralized enamel. Proper amount of fluoride is taken in during the development of teeth, so that the cusps are blunt and the fissure becomes shallow; this change in tooth morphology allows the tooth to be easily self-cleaning and provides enhanced resistance to caries formation. CN113197693A discloses an anticarious film, an anticarious solution, a dental appliance with the anticarious film and a method for forming the anticarious film on the dental appliance, wherein the main anticarious mechanism is that a coating containing fluoride is coated on a shell-shaped dental appliance body to achieve the function of fluoride anticarious. CN105232165A discloses a hidden orthodontic tooth socket with caries preventing ability and a caries preventing method, wherein the tooth socket comprises a tooth socket body, and a protective film is coated on the tooth socket body to play a role in preventing caries; the protective film is a fluorine protective agent in the fluorine-containing coating, the fluorine-containing gel or the fluorine-containing foam, and the protective film is coated on one side of the interior of the tooth socket body, which is close to the teeth. However, fluoride is added to generate fluoride ions, and the fluoride ions are continuously exuded to generate remineralization reaction with teeth, so that the long-term fluorine release capacity and fluorine release amount are difficult to maintain, the effect of preventing the orthodontic chalky stains for a long time cannot be achieved, and the problem of the orthodontic chalky stains cannot be fundamentally solved.
Therefore, the development of the caries-prevention invisible orthodontic appliance which can effectively prevent the colonization and propagation of dental plaque in the tooth socket and further can prevent chalk spots and has good antibacterial effect and long antibacterial time is an urgent technical problem to be solved in the field.

(2) Light transmittance: measuring the light transmittance of the sample at 550nm by using a spectrophotometer;
(3) The antibacterial rate is as follows: taking a bacterial suspension of the cultured streptococcus mutans (BNCC 336931, purchased from Beijing BeiNai Chuanglian Biotechnology research institute), dropwise adding 100 mu L of the bacterial suspension on a sample to be tested, uniformly coating for 20min, putting the sample into a 10mL test tube of PBS (phosphate buffer solution) by using sterile forceps, fully and uniformly mixing, and properly diluting; selecting 2-3 dilution gradients, sucking 1mL of diluent, inoculating the diluent to a plate by an agar pouring method, culturing the diluent at 35 +/-2 ℃ for 48 hours, and counting bacterial colonies, wherein two of each group are parallel; the samples were repeated 3 times and the inhibition was calculated as follows: x = (a-B)/a × 100%; in the formula: x represents the bacteriostatic rate (%); a represents the average colony number of the tested sample before oscillation; b represents the average colony number of the tested sample after shaking.
The caries preventing invisible orthodontic appliances provided in examples 1 to 7 and comparative examples 1 to 2 were tested according to the above test methods, and the test results are shown in table 1:
TABLE 1

Example 1 1.3 69.26 72.54
Example 2 1.2 65.18 76.67
Example 3 1.4 68.35 70.26
Example 4 1.3 60.27 65.28
Example 5 1.3 64.31 64.57
Example 6 0.7 59.86 55.34
Example 7 1.4 47.12 67.53
Comparative example 1 1.3 71.53 0
Comparative example 2 / 72.63 0
As can be seen from the data in table 1: the caries-preventing invisible orthodontic appliance provided by the invention has an excellent antibacterial effect.
Specifically, the fluidity of the antibacterial masking liquid adopted in the caries-preventing invisible orthodontic appliance obtained in the embodiments 1 to 5 is not lower than 1.2mm/min, so that more operation time can be provided for doctors in clinical operation, and the antibacterial coating can be more easily and uniformly coated; the light transmittance of the obtained anti-caries invisible orthodontic appliance is higher than 60%, and the difference of the light transmittance of the anti-caries invisible orthodontic appliance and the light transmittance of the anti-caries invisible orthodontic appliance (comparative example 2) which is not coated with the antibacterial coating is small, so that the wearing comfort and the attractiveness are not influenced by the arrangement of the antibacterial coating; the antibacterial tests show that the antibacterial rate of the anti-caries invisible orthodontic appliances obtained in the examples 1 to 5 is 64.57 to 76.67 percent, which shows that the anti-caries invisible orthodontic appliances can effectively inhibit the permanent planting of dental plaque and have excellent antibacterial performance.
As can be seen from comparison of example 1 and comparative examples 1 to 2, the orthodontic appliances obtained without adding an antibacterial agent to the coating or without directly providing an antibacterial coating have no antibacterial effect and are not very effective in preventing caries.
Comparing example 1 with examples 6 to 7, it can be found that the lower amount of the antibacterial agent in the antibacterial coating (example 6) causes the antibacterial property of the obtained orthodontic appliance to be reduced; while higher amounts of the antimicrobial agent in the antimicrobial coating (example 7) resulted in poor light transmission of the resulting orthodontic appliance.
Further comparison of examples 1 and 4 to 5 reveals that zinc oxide is most effective as an antibacterial agent.
The applicant states that the present invention is described by the above examples to provide an anti-caries invisible orthodontic appliance with an antibacterial coating, and a method for making and using the same, but the present invention is not limited to the above process steps, i.e., it is not meant that the present invention must rely on the above process steps to be implemented. It will be apparent to those skilled in the art that any modification of the present invention, equivalent substitutions of selected materials and additions of auxiliary components, selection of specific modes and the like, which are within the scope and disclosure of the present invention, are contemplated by the present invention.
