Description

A light-stimulated fluoride-releasing orthodontic accelerator

Technical areas:

The invention relates to the technical field of dental orthodontic instruments, and in particular to a light-stimulated fluorine-releasing orthodontic accelerator.

Background technique:

As the basic needs of our people continue to be met, people's emphasis on maxillofacial aesthetics continues to increase, and the demand for orthodontics in our country is growing year by year. Enamel demineralization is a common side effect of fixed orthodontic treatment, especially among adolescent patients. It has become a common clinical problem and has attracted widespread attention. Enamel demineralization refers to the phenomenon that when the pH value of the tooth surface decreases, the solubility of the enamel increases, and calcium and phosphorus precipitate, resulting in the appearance of chalky or yellow-white patches on the tooth surface. If the disease progresses further, it may even lead to tooth decay. A survey shows that the enamel demineralization rate of patients after orthodontic treatment is as high as 74%, which greatly affects the appearance of the tooth surface, increases the risk of dental caries, and harms oral health. The main reasons are that (1) fixed orthodontic technology requires bonding of brackets, and the acid etching step before bonding will cause calcium and phosphorus to precipitate in the enamel, leading to enamel demineralization; (2) brackets and archwires increase the size of the teeth. Difficulty in cleaning leads to accumulation of dental plaque, causing oral flora imbalance, and acidic metabolic products of bacteria lead to demineralization of tooth enamel.

Enamel demineralization not only seriously affects the appearance, but if not treated in time, the defect will accumulate dentin, causing dentin sensitivity, causing patients to suffer from a series of symptoms such as tooth soreness and pain. If the lesions continue to progress, it will lead to dental caries. The "Fourth National Oral Health Epidemiological Survey Report" shows that more than half of the country's population suffers from dental caries. Once enamel demineralization progresses to caries, it will lead to irreversible tooth damage, which will not only incur high treatment costs, but may also lead to pulpitis, apical periodontitis, and even tooth loss. At the same time, oral health and overall health go hand in hand. When dental caries becomes an infection focus, harmful metabolites or bacterial toxins in the focus area can be transferred to other organs through the blood or lymph, leading to systemic diseases such as rheumatoid arthritis, endocarditis, chronic nephritis, and retinitis, seriously affecting the physical and mental health of patients. Therefore, the prevention of enamel demineralization and caries is particularly important during orthodontic treatment.

Fluoride is a commonly used anti-caries antibacterial substance in clinical practice and plays an important role in preventing enamel demineralization during orthodontics. Appropriate concentration of fluoride ions can replace hydroxyapatite in tooth enamel to form more stable fluorapatite, thereby reducing the solubility of enamel and effectively preventing enamel demineralization. At the same time, fluoride ions can also combine with calcium and phosphorus in saliva to promote the redeposition of apatite crystals and facilitate the remineralization of demineralized parts. Not only that, research shows that fluoride ions can inhibit the storage of intracellular polysaccharides and the synthesis of extracellular polysaccharides of cariogenic bacteria, affect bacterial acid production and metabolism, and reduce the risk of caries. At present, the main way to prevent enamel demineralization is to apply fluoride on the teeth regularly in medical institutions, but this often increases the number of visits and chairside operation time. The main products used by medical institutions are fluorinated foam and fluorinated gel. Among them, fluorinated foam has poor anti-acid effect and anti-caries effect, while fluorinated gel has a relatively good effect, but no water is allowed within 2 hours after use. , fasting within 4 hours will cause a certain degree of inconvenience to the patient. In addition, patients can use fluoride mouthwash by themselves, but the concentration of salivary fluoride ions drops rapidly after each mouthwash, and the absorption of fluoride ions by tooth enamel is limited.

The current incidence of oral malocclusion in my country is as high as 72.97%, which seriously affects the physical and mental health and chewing function of patients. However, the current oral orthodontic treatment has clinical problems such as long treatment cycle and many complications. The applicant's approved patent number ZL202110840674.2 provides an adjustable near-infrared orthodontic accelerator for precise treatment, which shortens the orthodontic treatment course through a number of slidable laser emitting devices. However, the existing orthodontic accelerators have no obvious effect on improving enamel demineralization. At the same time, with respect to the daily use of near-infrared orthodontic accelerators, clinicians have no effective means to visually monitor patients' compliance with medical advice.

Contents of the invention:

1. Technical issues to be solved

The present invention aims to provide a light-stimulated fluoride-releasing orthodontic accelerator to solve the problem of enamel demineralization and dental caries caused by orthodontics that cannot be improved by the existing technology. Applying fluoride requires additional chairside operation time and increases the number of patient visits. Fluoride It takes a long time to fully interact with teeth, affects eating, and cannot visually monitor patient compliance.

(2) Technical solutions

In order to solve the above technical problems, the present invention adopts the following technical solution: a light-stimulated fluoride-releasing orthodontic accelerator, which includes a dental base cover, a tooth outer peripheral cover and an inner peripheral cover. The inner peripheral cuff of the tooth forms a U-shaped brace structure, and an alveol is provided between the outer peripheral cuff of the tooth and the inner peripheral cuff of the tooth. There is a fluoride pad on the side close to the alveolar. The fluoride pad is made of a combination of fluorine rubber and fluorosilicone rubber or food-grade silica gel, and is made into a microporous structure. The fluoride pad is filled with There is sodium fluoride, and the side of the fluoride pad on the tooth peripheral sleeve is provided with a concave orthodontic bracket receiving cavity, and a carbon dioxide laser light strip and a near-infrared laser light strip are arranged side by side in the tooth peripheral sleeve. , the near-infrared laser light strip is provided in the inner peripheral sleeve of the tooth, and a controller for controlling the carbon dioxide laser light strip and the near-infrared laser light strip is provided on the outside of the outer peripheral sleeve of the tooth, and the fluoride-added An indicator groove is provided on the side of the pad located on the tooth peripheral sleeve, and an indicator capsule is detachably provided in the indicator groove.

The tooth base sleeve, the tooth peripheral sleeve and the tooth inner sleeve form a U-shaped sleeve structure for sleeve on the teeth of an orthodontic patient, the patient's teeth are in the tooth sockets, the fluoride pad is fitted with the patient's tooth surface and the orthodontic bracket, and fluoride ions are slowly released under the light stimulation of the carbon dioxide laser light strip to apply fluoride to the patient's tooth surface. Compared with the traditional fluoride application method, it is more uniform, more comprehensive, and less technically sensitive. The orthodontic bracket accommodating cavity is used to wrap the orthodontic bracket surface of the orthodontic brace, and is a whole depression slightly shallower than the orthodontic bracket. In this way, when the orthodontic bracket is pressed into the orthodontic bracket accommodating cavity, excess material can move to the depression, the tooth corresponding to the orthodontic bracket part can be easily adapted, and the tooth surface in contact with the orthodontic bracket part can be adjusted. The surface is focused on strengthening fluoride coating, which is more targeted for the parts that are prone to demineralization during orthodontic treatment. The sodium fluoride in the fluoride pad can increase the molecular energy and fully release it under the stimulation of carbon dioxide laser. The microporous structure of the fluoride pad can promote the storage of fluoride gel. Fluoride ions are released slowly and continuously in the oral cavity at a concentration of about 0.05%, which is the recommended concentration for daily fluoride water mouthwash. It has good safety. Carbon dioxide laser can enhance the absorption of fluoride ions by tooth enamel, and can further increase the acid resistance of the tooth surface by reducing the carbonate content of tooth enamel. At the same time, it improves the mechanical properties of fluorapatite, reduces the action time of fluoride and tooth surface, and uses a smaller fluorine content to achieve the maximum fluorine absorption of the tooth surface, so that the fluoride ion action speed is faster and does not affect eating. The near-infrared laser light belt is used to perform near-infrared irradiation on the gums corresponding to the patient's tooth root to increase the movement speed of the teeth during orthodontic treatment. The controller is used to control the working mode of the carbon dioxide laser light belt and the near-infrared laser light belt to control the irradiation time of the carbon dioxide laser light belt and the near-infrared laser light belt, and at the same time ensure the fluoride coating effect and acceleration effect. The color of the indicator capsule can be gradually faded due to saliva flushing, and the color range presented after a certain period of time can be predicted based on the average salivary flow rate of the population. During follow-up visits, the color of the indicator capsule can be used to estimate the patient's orthodontic accelerator usage time and visually monitor patient compliance.

Furthermore, the fluoridation pad is provided with micro brush velvet, and the outer tooth sleeve and the inner tooth sleeve are provided with micro vibration motors close to the fluoridation pad. Driven by the micro vibration motor, the fluoridation pad and the micro brush velvet can remove the soft scale in the dead corner around the bracket where the enamel demineralization is easy to accumulate, and achieve accurate fluoride application and accurate prevention of caries. At the same time, the high-frequency low-intensity vibration massages the gums to promote local blood circulation and reduce the pain during orthodontic treatment.

Further, the fluoride pad is provided with several fluoride flow channels connected with the alveolus. The fluoride flow channel is used to maintain the flow rate of fluoride ions in the fluoride pad along the concentration gradient. Fluoride ions are continuously and slowly released along the concentration gradient at a concentration of about 0.05% for a long time, strengthening the fluoride ions on the surface and inside of the fluoride pad. The flow effect is controlled to maintain an appropriate rate of fluorine release and refilling. The fluorine flow channel can also be used to provide more space and surface area when replenishing fluorine-containing gel.

Furthermore, the fluoride pad is detachably connected to the tooth base sleeve, the tooth peripheral sleeve and the tooth inner sleeve, and a part of the fluoride pad provided with the orthodontic bracket accommodating cavity is the bracket part, and the bracket part and the fluoride pad are detachably connected. The microporous structure of the fluoride pad has the characteristics of being able to release and refill fluoride, is easy to use, provides high patient comfort, and does not cause loss of gingival tissue. After multiple follow-up visits, if the fluoride pad is incompatible with the orthodontic bracket of the orthodontic brace due to tooth movement, the entire fluoride pad can be disassembled and replaced as needed, or only the bracket part can be replaced to ensure durability and adaptability.

Furthermore, under the control of the controller, the carbon dioxide laser light belt and the near-infrared laser light belt can be turned on alternately or simultaneously to irradiate the tooth socket. The duration of one irradiation of the carbon dioxide laser light belt is 30 seconds, and the duration of one irradiation of the near-infrared laser light belt is 10 minutes. The carbon dioxide laser is recommended to be a pulsed laser, and the recommended safety parameters are a wavelength of 10.6μm, a repetition rate of 25Hz, a pulse width of 5ms, a pulse period of 40ms, a peak output power of 0.175W, and an energy density of 732mJ/ ^cm2 per pulse. The light emitted by the near-infrared laser light belt is a near-infrared laser with a wavelength of 810nm and a power density of 50-100mW/ ^cm2 , which is used to alternately or simultaneously apply fluoride and near-infrared acceleration to the patient's tooth surface.

Further, the surface of the indicator capsule is coated with an edible paint that becomes lighter in color as saliva washes it off.

Furthermore, the fluorinated pad can be synthesized by using fluorine rubber and fluorosilicone rubber in a ratio of 8:2. The structure synthesized according to this ratio is a uniform and loose sea-island structure. It is non-toxic after polymerization, has a stable structure and good safety. The internal microporous structure increases its adsorption and storage capacity for fluoride ions. Compared with ordinary silicone rubber, fluorine rubber or fluorosilicone rubber, this kind of synthetic rubber has better adsorption, heat resistance, cold resistance, high voltage resistance, oil resistance, acid and alkali resistance, etc. The fluoride-added pad can also be made of food-grade silica gel with microporous structure. Both of the above materials can contain sodium fluoride in the skeleton. After the accelerator is placed in the mouth, under the stimulation of carbon dioxide laser, the molecular movement is accelerated, causing It slowly diffuses out of the pores of the skeleton along the concentration gradient to achieve sustained release of fluoride ions.

Further, the dental base cover, the dental outer peripheral cover, the dental inner peripheral cover and the fluoride pad are all made of flexible and plastic transparent material. It can be adjusted according to the tooth shape of different patients and the shape of the orthodontic brackets for different tooth positions. The orthodontic bracket receiving cavity on the fluoride pad is a dental arch-shaped long depression, and its depth is slightly shallower than that of orthodontic correction. The height of the orthodontic brackets of the device can be personalized for different patients through its plasticity after being placed in the mouth, and is conducive to the transmission of carbon dioxide laser and near-infrared light. At the same time, as the position of the orthodontic bracket changes during the orthodontic process, the bracket portion provided with the orthodontic bracket receiving cavity can be replaced as needed, and the new bracket portion can be replaced by the orthodontic bracket. The groove is pressed into the orthodontic bracket receiving cavity to closely fit the orthodontic bracket to ensure adaptability, thereby achieving precise fluoride coating on the tooth surface in contact with the orthodontic bracket during the entire orthodontic process.

The present invention also provides an orthodontic accelerator storage box for use with the above-mentioned light-stimulated fluoride-releasing orthodontic accelerator, comprising a box body and a box cover, wherein the box body is provided with a flexible buffer pad, the flexible buffer pad is provided with two U-shaped placement grooves, and the box cover is provided with two U-shaped pressing blocks corresponding to the U-shaped placement grooves. Considering the loss in the gel transfer process, the U-shaped pressing blocks and the flexible buffer pad are both made of gel sponge material containing slightly more than 0.05% sodium fluoride.

The gel sponge is self-replaceable and releases fluoride for a long time. After the orthodontic accelerator is placed, the flexible cushion pad and the U-shaped pressing block wrap the orthodontic accelerator and squeeze it slightly, and the sodium fluoride gel seeps out from the sponge to replenish the fluoride ions in the fluoride pad. concentration to achieve fluorine recharging of the fluoride pad, which is convenient for long-term use.

The method of using the light-stimulated fluorine-releasing orthodontic accelerator of the present invention is as follows:

The patient puts the device into the oral cavity, and puts the teeth into the alveolus 4. The dental base cover 1, the outer peripheral sleeve 2 and the inner peripheral sleeve 3 wrap the tooth surface wearing the orthodontic appliance. The width of the dental base cover 1 It is set to be slightly smaller than the width of the patient's gums. After wearing it, it can be directly stuck on the teeth under its own elasticity, without the need to continue biting. It can be applied to various deformed tooth arrangements and shapes. The tooth is surrounded on three sides by the dental base 1, the outer peripheral sleeve 2 and the inner peripheral sleeve 3. The outer peripheral sleeve 2 is located on the outside of the patient's teeth. The fluoride pad 5 fits the patient's tooth surface and the orthodontic bracket. Under the carbon dioxide laser lamp The patient's tooth surface is coated with fluoride by slowly releasing fluoride ions under the stimulation of light with 7. The orthodontic bracket accommodating cavity 6 is used to wrap the outer surface of the orthodontic bracket 22 of the orthodontic appliance. It is a whole strip slightly shallower than the orthodontic bracket. The depression of the orthodontic bracket 22 is such that when the orthodontic bracket 22 is pressed into the orthodontic bracket accommodating cavity 6, the excess material can move to the depression, and the teeth can be easily adapted to the corresponding parts of the orthodontic bracket 22, and the teeth can be easily adapted to the orthodontic bracket 22. The tooth surface in contact with the orthodontic bracket 22 is heavily coated with fluoride. The sodium fluoride in the fluoride pad 5 can increase molecular energy under the stimulation of the carbon dioxide laser. The microporous structure of the fluoride pad 5 can make it in a high-concentration fluoride ion environment. It absorbs fluoride ions at high speed, and releases fluoride ions in the oral cavity continuously and slowly for a long time along the concentration gradient at a concentration of about 0.05%. Carbon dioxide laser can enhance the absorption of fluoride ions by the enamel, and can further increase the carbonate content of the enamel by reducing the carbonate content of the enamel. It improves the acid resistance of the tooth surface and improves the mechanical properties of fluorapatite. The synthetic rubber material or microporous food-grade silicone material used in the fluorinated pad 5 has better adsorption, heat resistance, cold resistance, and high voltage resistance than ordinary silicone rubber, fluorine rubber, or fluorosilicone rubber. properties, oil resistance, acid and alkali resistance, etc. It has a sea-island, microporous structure. Sodium fluoride is placed in the skeleton, and silica gel channels are used as the rate-limiting method to slowly release safe concentrations of fluoride ions along the concentration gradient to achieve efficient, non-invasive, automatic, continuous, and long-term fluoride ions. Ions are released, and the fluoride ion release concentration is controlled at 0.05%, which is the recommended concentration for daily fluoride water rinse and has good safety. Long-term slow release of fluoride can reduce the extra chairside operation time occupied by regular fluoride application, reduce the number of patient visits, and does not affect the patient's eating. The near-infrared laser light strip 8 irradiates the gums at the patient's tooth roots with near-infrared light to increase the movement speed of the teeth during the orthodontic process. The controller 9 is used to control the working modes of the carbon dioxide laser light strip 7 and the near-infrared laser light strip 8 , to control the irradiation time of the carbon dioxide laser strip 7 and the near-infrared laser strip 8 to ensure the fluorine coating effect and acceleration effect. Since the surface of the indicator capsule 11 is coated with edible paint, the color can continuously become lighter due to saliva washing. According to the average saliva flow rate of the population, the color range that will appear after a certain period of time is predicted. During follow-up visits, the patient's usage time of the orthodontic accelerator can be estimated through the color of the indicator capsule 11, and the patient's compliance can be visually monitored. After each follow-up visit, a new indicator capsule 11 can also be replaced. In addition, if the patient is an adolescent, in order to better monitor the patient's compliance, with parental consent, the patient's salivary flow rate can be measured to predict a more accurate color range, thereby conducting personalized compliance monitoring.

In summary, the light-stimulated fluoride-releasing orthodontic accelerator provided by the present invention solves the problems of enamel demineralization and caries caused by orthodontics which cannot be improved by the prior art. Fluoride application requires additional chairside operation time, increases the number of patient visits, takes a long time for fluoride to fully react with teeth, affects eating, and cannot visually monitor patient compliance.
