The application discloses a dental appliance with a caries prevention function and a preparation method thereof, wherein the components for preparing the silica gel dental appliance comprise A-component adhesive, B-component adhesive and fluoride which are combined according to a preset proportion. Namely, when the dental appliance is prepared, fluoride is added into raw materials for preparing the silica gel dental appliance, so that the prepared silica gel dental appliance contains fluoride, and when a user wears the dental appliance, the fluoride in the dental appliance is continuously released to the tooth surface through saliva in the oral cavity, so that the effect of preventing dental caries is achieved.
Description
Technical Field
The application relates to the technical field of medical supplies, in particular to a dental appliance with a caries prevention function and a preparation method thereof.
Background
Misjaw deformity is a common oral disease in children, and can affect the beauty, growth and development, chewing and language functions of the jaw face of the children. Investigation shows that the incidence rate of the children malocclusion exceeds 60 percent in China. In the early stages of the growth and development of children, it is necessary to treat and correct the misjaw deformity which may and may have occurred in time. However, children are very prone to caries during the appliance, as wear of the appliance can prevent oral hygiene. Research shows that the number of cariogenic bacteria increases significantly after 6 months after placement of the fixed appliance in the mouth. At the same time, saliva flow rate and buffering capacity also change. With the most common fixed appliances, 46.2% of patients develop chalky or chalky exacerbations 6 months after the initiation of orthodontic; caries or caries exacerbations occur in 20.2% of patients who begin orthodontic treatment for 6 months. Even if oral cleaning is strictly performed, dental caries is liable to occur in patients during orthodontic treatment. When the movable appliance is used, caries, loss and tooth filling number of the sick children are obviously increased (caries becomes more serious), and lingual plaque accumulation is also increased.
In view of the above problems, a current solution is to apply a fluoride film formed of fluoride to the inner side of the dental appliance when manufacturing the dental appliance, so that fluoride ions are released from the fluoride film by saliva when the user wears the appliance. However, since the fluorine film formed of fluoride is directly in contact with saliva in the oral cavity, the fluoride is rapidly released in a short time. Therefore, the effect of sustained release of fluorine cannot be achieved. And because the fluoride ions are released from the fluoride film into the oral cavity in a short time, the concentration of the fluoride ions in the oral cavity is higher than the safe concentration, and the fluoride ions are further unfavorable to the health of a human body.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. The present application may be embodied in many other forms than those herein described, and those skilled in the art will readily appreciate that the present application may be similarly embodied without departing from the spirit or essential characteristics thereof, and therefore the present application is not limited to the specific embodiments disclosed below.
Referring to fig. 1, a schematic diagram of a dental appliance with caries preventing function according to the present application is shown, and H1, H2, H3, and L1 in fig. 1 may have different size combinations to adapt to different patient needs. The components of the dental appliance include an A-component gel, a B-component gel, and a fluoride in combination in a predetermined ratio. Specifically, fluoride, A component glue and B component glue which are used for synthesizing a silica gel product are selected according to a preset proportion and are placed into a mixing container, wherein the A component glue and the B component glue in the mixture undergo a curing reaction to generate the silica gel product. The fluoride in the mixture does not react with the A-and B-component gums, and therefore, the fluoride is incorporated into the silica gel article formed from the A-and B-component gums. The component A glue and the component B glue are two fluid substances for mixing to generate silica gel, and can react in a short time after being mixed to form a solidified silica gel state, so that the molding is convenient; in the dentist field, often used, there are a number of possible implementations of both specific component materials in the field; and are not described in detail herein, as they are not material to the present application.
It is noted that the gel has micropores open to the tooth appliance contact surface and having different diameters through which the fluoride is released to the tooth surface. Specifically, the average diameter of the micropores with different diameters is obtained by adjusting the conditions in the preparation process, wherein the adjusting the conditions in the preparation process comprises: the pore diameter in the dental appliance is adjusted by adjusting the amount of pressure during injection molding during preparation.
Specifically, the component A glue, the component B glue and the fluoride are uniformly mixed. The fluoride is uniformly distributed in the mixture, at the moment, the A component glue and the B component glue in the mixture react to generate a silica gel product with a micropore structure, and the fluoride is adsorbed into micropores of the silica gel just uniformly in a solid state because the fluoride does not react with the A component glue and the B component glue, and the fluoride in the tooth appliance does not influence the process of generating the silica gel product by the chemical reaction of the A component glue and the B component because the fluoride accounts for a small proportion in the tooth appliance. In specific implementation, the proportion of the fluoride is determined according to the specification requirement of the product. After the component A glue, the component B glue and the fluoride are uniformly mixed, injecting the mixed material into a die through a glue injection machine, detecting whether impurities or bubbles exist in the silica gel or not at all in the glue injection process, and discharging the impurities or the bubbles if the impurities or the bubbles exist. After the glue injection of the glue injection machine is finished, applying different pressures to the mixed materials in the mould through the pressurizing equipment, and keeping the pressures until the drying and shaping of the silica gel product in the mould is finished, so that the silica gel tooth appliance generated through the process has different micropore diameters.
It should be noted that saliva may permeate into the pore structure of the silica gel during the process of wearing the dental appliance by the user, and the pore diameter may affect the permeation rate of saliva, and the pore diameter may also affect the contact area of fluoride in the pores with saliva, so that it is known that the release rate of fluoride in the dental appliance is directly related to the pore diameter. Therefore, in the process of preparing the dental appliance, the pressure applied by the pressure applying device in the injection molding step can be adjusted, thereby adjusting the micropore diameter of the prepared silica gel appliance. It has also been found from experiments that the release rate of fluoride in the dental appliance is related not only to the internal pore diameter of the silica gel, but also to the content ratio of fluoride in the appliance, the higher the content ratio of fluoride, the more massive the release rate of fluoride, the lower the content ratio, the slower the release rate of fluoride, and because the fluoride is filled in the microporous structure of the silica gel in solid form in the dental appliance. Accordingly, after the user wears the appliance, the fluoride content of the appliance is gradually reduced due to the sustained release of the fluoride, so that the release rate of the fluoride in the appliance is gradually reduced, and referring specifically to fig. 2, fig. 2 is a graph showing the concentration of fluoride in deionized water solution versus time (days) for a sample of the appliance. Specifically, disc samples of 10mm diameter and 2.5mm thickness were prepared, 6 samples were prepared, each sample was immersed in 0.2ml deionized water at the same time, and the samples were exchanged to the next soak at the same time every day until 21 days, and the daily fluoride ion release amount (ppm/d) per unit area of each sample was calculated and the average value was plotted as a "time-fluoride ion concentration" graph. As shown in fig. 2, in the early stage of wearing the dental appliance by the user, the prepared dental appliance releases fluoride ions, and at this time, the high-speed released fluoride ions just react with the teeth of the user to remineralize the teeth of the user, so that the high-speed released fluoride ions in the dental appliance can not have adverse effects on the body of the user in the initial stage of wearing, and the speed of releasing fluoride ions of the dental appliance is lower and lower along with the increase of wearing time, and at this time, the low-speed released fluoride ions can timely supplement lost fluoride ions, and the side effect of too high fluoride can be avoided. It should be noted that for each user's dental situation, it is necessary to wear an appliance having a corresponding predetermined release rate that matches the user's dental situation, and this will not be described in detail.
Based on the above, it can be seen that there is a need to match a different release rate of the appliance for each user's dental condition, and the release rate of fluoride in the appliance can be adjusted in three ways.
And (I) adjusting the release ratio of fluoride in the dental appliance by adjusting the predetermined proportion of fluoride selection material when the diameter of the micropores is fixed so that the dental appliance has different release speeds during the appliance.
And (II) adjusting the release rate of fluoride from the dental appliance by adjusting the pore diameter at a predetermined selected ratio of fluoride such that the fluoride release rate is different during appliance correction.
And (III) simultaneously adjusting the pore diameter and the predetermined proportion of fluoride material to adjust the rate of fluoride release in the dental appliance during appliance.
It should be noted that, the present application can select a proper predetermined ratio and a pore diameter according to the tooth condition of each user who needs to straighten teeth, so that the dental appliance has different release rates of fluoride during the correction, and thus has different anticaries effects on the teeth of the wearer. Specifically, in the early stage of wearing the dental appliance by the user, the prepared dental appliance releases fluoride ions at high speed, at this time, the concentration of fluoride ions in the oral cavity is kept in a relatively high interval, the teeth of the user are just remineralized, along with the increase of wearing time, the speed of releasing the fluoride ions by the dental appliance is lower and lower, and then in the later stage of wearing, the fluoride released by the dental appliance can supplement the lost fluoride ions in time, and the side effect of too high fluoride can be avoided. Therefore, the dental appliance with different preset proportions and micropore diameters can be selected according to the tooth condition of the user so as to meet the requirements of preventing and controlling dental caries.
Preferably, the fluoride comprises a fluorine-containing organic or inorganic compound, for example, not limited to one or more of the following molecules: sodium fluoride, sodium monofluorophosphate, stannous fluoride, fluorosilicic acid, sodium fluorosilicate, fluorophosphate, fluorosilane, and the like.
Optionally, the ratio of the component a glue to the component B glue is determined according to preset requirements, specifically, the content of fluoride in the preset ratio in the process of preparing the dental appliance with the caries prevention function is determined according to the tooth condition of the wearer, specifically, the ratio of fluoride in the dental appliance is adjusted according to the dental diagnosis result for the wearer, for example, the ratio of fluoride content is in the following range: fluoride is more than or equal to 0.01% and less than or equal to 15%; the component A glue and the component B glue occupy the residual proportion.
Optionally, the release rate is at least greater than 24 hours for good anticaries treatment of the dental appliance.
Optionally, the component A glue and the component B glue respectively comprise the following combination modes: the proportion of the component A glue to the component B glue is equal to 1:1 or other ratio.
Corresponding to the dental appliance with the caries preventing function, the application also provides a preparation method of the dental appliance with the caries preventing function. Referring specifically to fig. 3, fig. 3 is a flowchart illustrating a method for manufacturing a dental appliance according to the present embodiment, and the same parts as those of the dental appliance with caries prevention function are not described herein, but refer to the corresponding parts of the dental appliance with caries prevention function.

Step 2: mixing, namely uniformly mixing the component A glue, the component B glue and the fluoride, wherein the fluoride is uniformly distributed in the mixture on the premise that the component A glue and the component B glue can fully react in the step, and the concrete mixing process is as follows, stirring for 20-45 seconds by a glue stirring rod, and putting the mixture into a glue stirring machine. Setting stirring parameters, such as rotational speed: 1500-3000 turns, time: 200-300 seconds.
