Description

Technical Field

[0001] The utility model belongs to the field of tooth prevention and health care products, and specifically relates to a personalized customized tooth cleaning and care toothbrush and a usage method thereof. Background Art

[0002] Dental plaque is the initiating factor of caries and periodontal disease. Failure to effectively remove dental plaque will cause caries, gingivitis, and periodontal disease. Brushing your teeth with a toothbrush, as well as flossing and interdental brushes can effectively remove dental plaque. The current status of Chinese people's brushing habits is that 36.1% of adults brush their teeth twice a day. 42.1% of 12-year-old children brush their teeth twice a day. A German study in 2018 used video recording analysis to find that no matter what type of toothbrush is used to brush teeth, most people's brushing action pattern is habitually brushing in circles or back and forth, and the effect of the toothbrush is not fully achieved. The internationally recognized brushing method is the modified Bass brushing method, referred to as the Bass brushing method, also known as the horizontal vibrating brushing method, which is relatively complex and difficult to master. The Bass brushing method includes a horizontal vibration part and a brushing part. The horizontal vibration part requires that when brushing teeth, the bristles of the toothbrush are at a 45-degree angle to the teeth, so that the bristles enter the gingival sulcus at the neck of the teeth, and the bristles are placed on the gums, with slight pressure, and move back and forth in small and gentle circles or short distances at the neck of the teeth. There is no fixed specific value for the distance the toothbrush moves horizontally. Many people are not familiar with these anatomical structures at the neck of the teeth. Many people do not know that the bristles of the toothbrush are at a 45-degree angle to the teeth and vibrate horizontally at the neck of the teeth for a short distance. Therefore, how to brush teeth correctly is a pain point for people when brushing teeth.

[0003] The current electric toothbrush products all simulate the brushing part of the Bass brushing method. The brushing part mainly cleans the plaque on the lip (cheek) and tongue (palate) sides of the crown of the teeth, and removes the dirt brushed out by the horizontal vibration method. However, the lip (cheek) and tongue (palate) sides of the crown are the easiest to clean. The buccal and lingual sides of the teeth, as well as the neck and interproximal spaces are irregularly protruded and depressed, which are very easy to accumulate food residues and form plaque. The horizontal vibration part is a method for cleaning the most difficult parts of the teeth, such as the neck and gingival sulcus. Therefore, it is urgent to solve the problem of popularizing the horizontal vibration method of the Bass brushing method.

[0004] When cleaning the neck of the tooth, since the bristles of existing toothbrushes are basically flat, the protruding part of the tooth is easy to clean, but the concave part is difficult to clean. In order to clean the concave part, people often use great force to brush their teeth horizontally and vertically. Excessive force or too hard bristles or too large a horizontal brushing will cause excessive wear of the tooth hard tissue at the neck of the tooth, forming a wedge-shaped defect. According to incomplete statistics, the incidence of wedge-shaped defects in my country is as high as 34.9%-59%. Therefore, the strength of brushing teeth is a pain point and blind spot for people to brush their teeth.

[0005] The bristles of toothbrushes currently on the market are basically flat or have concave and convex curved surfaces, but they are not compatible with the concave and convex curves of the inner and outer (cheek and tongue) sides of the teeth. In order to clean the concave parts, users often press the bristles hard on the neck of the teeth, deforming the ends of the bristles and extending them into the concave parts of the teeth, and then brushing them back and forth horizontally. The concave parts of the teeth are cleaned. Excessive force or too hard bristles or excessive horizontal brushing will cause the protruding parts of the neck of the teeth to wear and form wedge-shaped defects, and the gums at the protruding parts of the teeth will often be damaged, bleeding and retracted. According to incomplete statistics, the incidence of wedge-shaped defects in my country is as high as 34.9%-59%. Therefore, the intensity of brushing is a pain point for people when brushing their teeth.

[0006] With the development of the national economy, more and more people with uneven teeth are receiving orthodontic treatment. Orthodontic teeth often require fixed devices, such as brackets and archwires. Brackets are bonded to the teeth, so it is very difficult to clean the teeth of people receiving orthodontic treatment, which is very likely to cause caries and gingivitis.

[0007] With the aging of the population, the incidence of periodontitis and dental caries has increased year by year. For elderly people with periodontitis, the roots of their teeth are exposed in the mouth to varying degrees. The shapes of the exposed roots are very irregular and difficult to clean. Since the elderly have reduced saliva secretion and often eat soft and rotten food, dental caries at the roots of their teeth are rampant. In addition, it is difficult to popularize regular periodontal medication in hospitals. With the aging of the population and the popularity of dental implants, more and more middle-aged and elderly people have dental implants in their mouths. The periodontal tissues of dental implants are more fragile than those of normal teeth. Poor cleaning often leads to peri-implantitis and eventually causes the implants to fall off. Summary of the invention

[0008] In order to solve the deficiencies in the prior art, the utility model provides a personalized cleaning and care toothbrush for cleaning teeth and a method of using the same, which allows users to clean their teeth in a scientific way and develop good brushing habits, while allowing users with periodontal disease to conveniently rinse and apply medication to periodontal pockets.

[0017] Preferably, the bristle tufts, hoses and water nozzles can be customized according to the position and shape of the user's teeth, gums, periodontal pockets and implant neck. The distribution and arrangement of the bristle tufts and water nozzles can be designed according to the structure of the orthodontic bracket.

[0018] Preferably, the personalized customization also includes designing the limit value of the spacing distance at the ends of the bristle clusters and setting the pressure applied to the teeth along the axis of the bristle clusters according to the position and shape of the user's teeth, gingival sulcus, periodontal pockets, restorations, orthodontic and other treatment devices, the physiological and pathological conditions of the anatomical structures in the user's mouth, and the user's needs.

[0019] Preferably, bristle clusters of different materials and diameters are provided, and different processing methods are used for the bristle clusters according to the physiological and pathological structures of the cleaned parts and the treatment devices such as restoration and orthodontics.

[0020] The bristle cluster uses extremely soft bristles and bristles with finer diameters when brushing the neck of the implant tooth or the wedge-shaped defect area of ​​the neck of the tooth. The bristle cluster is made of nylon or PBT, and is rounded.

[0021] The bristles used for brushing the neck of natural teeth are softer and thinner in diameter, made of nylon, TPR, PP, and the bristle clusters are rounded;

[0022] When brushing the occlusal surfaces of orthodontic brackets and crowns, you can use slightly harder bristles with a slightly larger diameter, made of nylon, TPR, or PP.

[0023] Preferably, a vertical protrusion is provided at the midline of the handle, and the U-shaped large bracket and the half-side bracket of the toothbrush bracket are provided with marking points for positioning the toothbrush in place, and the vertical protrusion on the handle is aligned with the user's nose tip, philtrum or glabella point;

[0024] A limiting member is provided on the large U-shaped bracket to limit the horizontal movement range of the toothbrush;

[0025] According to the specific structure of the toothbrush, the toothbrush bracket is provided with marking points, the number of which is greater than or equal to 3, and the marking points correspond to 3 or more of the 16 markings, namely, the occlusal surfaces of the central incisors on the left and right sides of the upper and lower jaws of the user, the cusps of the upper and lower canines, the buccal canines of the maxillary first premolars, the buccal and lingual cusps of the maxillary second premolars, and the first buccal cusp of the maxillary first molar; the marking points are used for the positioning of the toothbrush bracket to ensure that the bristle cluster is placed at the neck of the tooth, the interproximal space, the gingival sulcus, or the position of the restoration or orthodontic treatment device;

[0026] Pressure sensors are arranged inside the parts where the marking points are arranged, such as the bracket, and when 3 or more marking points are lightly pressed, the device will give a sound prompt to precisely place them.

[0027] Preferably, an optical element is disposed inside the handle for positioning the toothbrush in place, and the optical element on the handle emits a light beam to illuminate the user's facial marker points such as the nose tip, midpoint of the nose wing, point between the eyebrows, bottom of the earlobe, and midpoint of the tragus.

[0028] The utility model also provides a method for using a personalized toothbrush for cleaning and caring teeth. The toothbrush used in the method for using the personalized toothbrush for cleaning and caring teeth is the aforementioned personalized toothbrush for cleaning and caring teeth, comprising:

[0029] When the user has normal tooth arrangement and a mark point is set on the toothbrush holder, and the tooth mark point is aligned with the mark point on the holder to determine the position, when cleaning the front teeth, use the front toothbrush, the user looks in the mirror, holds the handle, opens the mouth, and puts the toothbrush into the mouth. The user observes through the mirror that the vertical protrusion on the handle is aligned with the tip of his nose, philtrum, or point between the eyebrows, and gently places the toothbrush between the upper and lower teeth. The user observes through the mirror that the tips of the canines of the upper and lower jaws on both sides touch the U-shaped large bracket, and the tips of the mandibular canines on the left and right sides face the mandibular canine mark points on the left and right sides of the U-shaped large bracket, and the tips of the maxillary canines on the left and right sides face the maxillary canine mark points on the left and right sides of the U-shaped large bracket. When three mark points are touched at the same time, the device gives a sound prompt to accurately place the tooth.

[0030] When the user has normal tooth arrangement and an optical element is set on the handle for positioning, dual positioning of facial landmarks and tooth landmarks can be adopted. When cleaning the posterior teeth, a posterior toothbrush is used. The user holds the handle, opens his mouth, puts the toothbrush into the mouth, and the U-shaped large bracket touches the top of the mandibular teeth. The user observes through a mirror that the vertical protrusion on the handle is aligned with the structures on the midline such as his nose tip, philtrum, or glabella. The optical element on the handle emits a light beam to illuminate the user's face nose tip, midpoint of nose wing, glabella, bottom of earlobe, and midpoint of tragus. At this time, the toothbrush is accurately in place. At this time, the user can also observe through a mirror that the tips of his mandibular canines on both sides lightly touch the mandibular canine landmarks on both sides of the U-shaped large bracket, and the occlusal surfaces of the mandibular central incisors on both sides lightly touch the 42 landmarks of the mandibular central incisors on both sides of the U-shaped large bracket. When three landmarks on the bracket are touched at the same time, the device gives a sound prompt to indicate that the toothbrush is accurately placed.

[0031] Preferably, when using a front toothbrush, after the toothbrush is in place, the toothbrush is manually or automatically driven to vibrate 7-10 times in a short distance in the horizontal direction, and the user opens the mouth and takes the toothbrush out of the oral cavity. At this time, the lower jaw moves downward, and the bristle cluster moves toward the crown direction of the mandibular teeth to brush the buccal and lingual sides of the mandibular teeth, while taking out the dirt brushed by the horizontal vibration. Then, the user holds the handle and moves the toothbrush downward to dislocate the toothbrush from the teeth. At this time, the bristle cluster moves downward to brush the buccal and lingual sides of the maxillary teeth, while taking out the dirt brushed by the horizontal vibration.

[0032] When using a toothbrush for the back teeth, taking the example of cleaning the back teeth on both sides of the lower mouth at the same time, after the toothbrush is in place, it is vibrated in the horizontal direction with a small amplitude and short distance for 7-10 times. Then the user opens his mouth, holds the handle to lift the toothbrush, and takes the toothbrush out of the mouth. At this time, the bristle cluster moves toward the crown direction of the mandibular teeth, brushing the buccal and lingual sides of the mandibular teeth, and at the same time removing the dirt from the horizontal vibration brushing.

[0033] Preferably, the toothbrush is provided with a water spray port, which is arranged on the toothbrush bracket. Water is sprayed by the water spray port, and the sprayed constant temperature water flow is used to clean teeth and massage gums. The water flow includes a direct current water jet, a pulsed water jet, and a micron and nano bubble water jet. A bubble generating device is used to generate bubbles to provide micron and nano bubble water to the water inlet.

[0034] The beneficial effect of the utility model is that, compared with the prior art,

[0035] 1. The prior art requires the user to have knowledge of the difficult anatomical structures such as the neck of the teeth, gingival sulcus, and interproximal space, and the user needs to know that the bristles of the toothbrush are at a 45-degree angle to the teeth. The user also needs to understand the essentials of brushing teeth such as the horizontal vibration method of the Bass brushing method and the short-distance horizontal vibration at the neck of the teeth. The utility model uses a relatively simple method to align the toothbrush with the facial and tooth landmarks, and the motor drives the toothbrush to perform short-distance horizontal vibration movement in the horizontal direction. Basically, the user does not need to know how to brush teeth correctly, and does not need to have an in-depth understanding of the anatomical structure of the teeth. It also solves the problem of large-scale horizontal brushing and the problem of difficulty in brushing teeth by vibration method for elderly people with diseases such as osteoarthritis;

[0036] 2. The electric toothbrush in the prior art can only realize the brushing method in the Bass brushing method; in addition, when brushing the inner side of the upper and lower front teeth, the Bass brushing method is limited by the shape of the toothbrush, the size of the mouth, and the degree of mouth opening, and it is impossible to brush the teeth with the horizontal vibration method. The toothbrush can only be held upright to brush the inner side longitudinally. The present invention realizes horizontal vibration and brushing of the whole mouth of teeth;

[0037] 3. In the Bass brushing method, the toothbrush needs to be slightly pressurized in the horizontal vibration part. The existing technology cannot control the brushing force. However, the utility model is based on the user's teeth, gingival sulcus, periodontal pockets, the position and shape of the restoration, orthodontic and other treatment devices, the physiological and pathological conditions of the anatomical structure in the user's mouth, and the needs of the user. The spacing distance at the end of the bristle cluster is personalized by the oral professionals, and the spacing distance limit is set by the oral professionals. A small range of adjustments can be made above the limit to set the pressure applied to the teeth along the axis of the bristle cluster. The brushing force does not need to be manually controlled. It is a pre-designed and customized finished product to prevent the user from applying too much force on the teeth and gums;

[0038] 4. The prior art cannot prevent large-scale horizontal sawing-type brushing. However, a limiting member is provided on the large U-shaped bracket of the utility model. The limiting member 36 is kept at a certain distance from the teeth and is adapted to the shape of adjacent teeth, thereby limiting excessive horizontal movement of the toothbrush and preventing large-scale horizontal movement of the teeth from causing wear and tear such as wedge-shaped defects and damage to the gums.

[0039] 5. In the prior art, cleaning the hard tissues of teeth and hard and irregular devices such as orthodontics, the neck of teeth and gingival sulcus, and the special neck of implants requires the use of toothbrushes of different materials and treatments, and the toothbrushes need to be replaced when brushing teeth. The utility model sets bristle clusters of different materials and diameters according to the physiological and pathological structures of the cleaned parts and the treatment devices such as repair and orthodontics, and uses different processing methods on the bristle clusters. It can clean the teeth in the same area without changing the toothbrush, which can fully clean the teeth, implants, orthodontic treatment devices and teeth, protect the health of the gums and periodontal tissues of the teeth, and also improve the comfort of the user;

[0040] 6. In the prior art, teeth with orthodontic brackets and devices such as brackets are extremely difficult to clean. The neck of the teeth, gingival sulcus, and interproximal space are difficult to clean. The special neck of the implant is often ignored when brushing. The bristle clusters of the toothbrush of the utility model are adapted to the orthodontic teeth and brackets, the neck of the teeth, gingival sulcus, interproximal space, and the special neck of the implant. In addition, the bristle clusters with special distribution and different arrangement directions are designed according to the structure of the orthodontic bracket. The utility model can simultaneously clean the irregular areas that are difficult to clean, such as the teeth and the restorative treatment device;

[0041] 7. The prior art does not have the function of applying medicine to the gingival sulcus and periodontal pockets. The utility model designs a hose structure, which is connected to the liquid storage bottle through a pipeline in the toothbrush holder. It is specially used for flushing and applying medicine to the gingival sulcus and periodontal pockets, and is used for daily home treatment of gingivitis and periodontitis.

[0042] 8. In the prior art, patients with periodontal disease need to use a toothbrush and an interdental brush to clean their teeth. The personalized toothbrush in the present invention is equivalent to a toothbrush plus an interdental brush. After brushing their teeth with a toothbrush, patients with periodontal disease do not need to use an interdental brush to clean their teeth.

[0043] 9. In the prior art, one toothbrush usually brushes one surface of two teeth at the same time, and all surfaces of all teeth need to be cleaned one by one, which is time-consuming and labor-intensive. The utility model designs a front toothbrush and a back toothbrush to clean 4-10 teeth, or even multiple surfaces of more teeth, at the same time. Only 2-3 toothbrushes are needed. After correct alignment, they can be vibrated horizontally 7-10 times and then the toothbrushes can be removed. This saves time, labor and efficiency.

[0044] 10. In the prior art, although the U-shaped toothbrush can brush all the teeth at the same time, in order not to damage the gums, the bristles are extremely soft and do not fit the user's tooth shape, and cannot effectively clean the tooth neck, interproximal spaces, gingival sulcus and other difficult-to-clean areas. The utility model designs a personalized toothbrush that fits the user's tooth shape, greatly improving the cleaning efficiency of the tooth neck, interproximal spaces, gingival sulcus and other areas.

DETAILED DESCRIPTION

[0062] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The embodiments described in this application are only part of the embodiments of the utility model, not all of them. Based on the spirit of the utility model, other embodiments obtained by ordinary technicians in this field without creative work are all within the scope of protection of the utility model.

[0063] Professional term: The central incisor is the first incisor on the midline of a person, one on each side, a total of 4 incisors, which is a professional term. The long axis of the tooth is the geometric axis that runs longitudinally through the tooth and passes through the center of the tooth. The long axis direction of each tooth is different. Figure 3 The solid line A is the long axis of the mandibular central incisor. The side of the tooth close to the lips is called the labial side, and the side close to the tongue is called the lingual side. The side close to the buccal mucosa is called the buccal side. The direction of the tooth close to the nose tip and philtrum is the mesial side, and the direction away from the nose tip and philtrum is the distal side. The gingival sulcus 9 refers to the narrow annular gap between the free gingiva 12 and the tooth surface. The normal depth range is 0.5-3mm. When the depth of the gingival sulcus 9 exceeds 3mm, it is usually considered pathological. The pathologically deepened gingival sulcus 9 is called a periodontal pocket.

[0064] like Figure 1 As shown, the interproximal space 2 of the crown and the interproximal space 3 of the root (in the case of periodontal disease) are both interproximal spaces of the teeth. Figure 2 yes Figure 1 The top view along the a-a' section, Figure 2 The V-shaped dotted area in the figure is the interproximal space 2 of the crown. The cervical region 1 is the protruding and recessed area of ​​the tooth neck. The interproximal spaces of the teeth (interproximal space 2 of the crown, interproximal space 3 of the root) and the recessed area of ​​the cervical region 1 as well as the gingival sulcus 9 are very easy to accumulate food residues and are difficult to clean, thereby forming plaque, leading to caries and periodontal disease.

[0065] Since the arrangement of human dental arches is different, the number of teeth covered by the toothbrush is designed according to the specific arrangement of the user's teeth. Since the front teeth are usually arranged in an arc shape and the premolars and molars at the back are basically arranged in an approximately straight line, the tooth cleaning and care toothbrushes are divided into two categories: front teeth toothbrushes and back teeth toothbrushes.

[0066] Since the canines are located at the corner of the dental arch, there are three situations for the arrangement and cleaning of the canines according to the specific situation of the user's tooth arrangement. The first situation: when the canines and incisors are arranged in a straight line (square circular dental arch), use a front toothbrush to clean the canines and incisors. The second situation: the canines are located at the corner of the dental arch, and the half of the canine close to the incisor is arranged in a straight line with the incisor, and the half close to the back teeth is arranged in a straight line with the back teeth. Therefore, it can also be designed that the toothbrush for the front teeth covers and cleans the half of the canine close to the incisor, and the toothbrush for the back teeth covers and cleans the half of the canine close to the back teeth. The third situation: the incisors are arranged in an arc, and the canines and the premolars and molars behind them are basically arranged in an approximate straight line. Therefore, in this manual, if Figure 4 As shown, the bristle clusters 32 of the front teeth area cover the upper and lower incisors of the user, a total of 8 teeth. The marking points on the U-shaped bracket 7 are used for positioning the toothbrush, so in the first, second and third cases of the canines, the U-shaped bracket 7 needs to extend to the canines for canine positioning.

[0067] Front toothbrush, such as Figure 4 and Figure 3 As shown, it includes two half-side brackets, which are respectively located on the upper and lower sides of the curved part of the U-shaped large bracket 7, including the inner and outer sides of the maxillary bracket and the inner and outer sides of the mandibular bracket, and the longitudinal section is H-shaped (as shown in FIG. Figure 3 shown);

[0068] The first situation of the back teeth toothbrush: in order to reduce the foreign body sensation and prevent nausea, it is divided into two toothbrushes for cleaning the upper back teeth and the lower back teeth, referred to as the upper back teeth toothbrush and the lower back teeth toothbrush for short. Figure 7 A toothbrush for the back teeth of the lower half of the mouth is shown. The toothbrush comprises two half-side brackets on the left and right sides, and the two half-side brackets are respectively located on the upper side or lower side of the ends of the straight parts of the horizontal parts of the bilateral brackets, including the inner and outer parts of the left maxillary bracket, and the inner and outer parts of the right maxillary bracket, or including the inner and outer parts of the left mandibular bracket, and the inner and outer parts of the right mandibular bracket, and the half-side bracket is connected to the horizontal U-shaped large bracket 7 through a curved connecting rod 34;

[0069] like Figure 16-1 As shown, the U-shaped large bracket 7 is substantially horizontal. Since most of the tooth landmarks are located on the outer (lip and cheek) side of the teeth, the U-shaped large bracket 7 is arranged close to the outer (lip and cheek) side of the teeth. Figure 16-2 is the cross section of the bent connecting rod 34, such as Figure 16-2 As shown, the curved connecting rod 34 is horizontal at the crown, and the U-shaped large bracket 7 constitutes a part of the horizontal part of the curved connecting rod 34. One side of the curved connecting rod 34 extends to the lingual side of the cleaned tooth, and the other side of the curved connecting rod 34 extends to the buccal side of the cleaned tooth.

[0070] The curved connecting rod 34 of the toothbrush may be provided with a structure that can slightly adjust the length, which may be, but is not limited to, a push-in ferrule connector structure, such as Figure 16-2 As shown, the soft sleeve 37 can be inserted into the protruding portion 38 of the ferrule structure along the direction of the arrow, such as Figure 16-3 As shown, after the sleeve 37 and the protruding portion 38 of the ferrule structure are installed, a certain distance L can be left. If the user feels that the force of the end of the bristle cluster 32 pressing on the gums 12 and the tooth neck 1 is not enough to clean the teeth well, the user can continue to push in to reduce the distance L, such as Figure 16-4 As shown, the distance L = 0, at which time the pressure of the end of the bristle cluster 32 pressing on the gums 12 and the tooth neck 1 is the limit value set by the doctor or professional. This limit value is determined by the actual pressure applied by the bristle cluster 32 on the teeth and gums 12, the classification of the user's gum biotype (thick type and thin type), whether the gums 12 bleed during use, the user's subjective feelings, and other factors.

[0071] The second situation of the back teeth toothbrush: in order to reduce the foreign body sensation and prevent nausea, it is divided into two toothbrushes for cleaning the upper and lower back teeth on the left side, or the upper and lower back teeth on the right side, referred to as the left half-mouth back teeth toothbrush and the right half-mouth back teeth toothbrush. It includes two upper and lower half-side brackets on one side, and the two half-side brackets are respectively located on the upper and lower sides of the ends of the straight part of the horizontal part of the bracket on the same side, including the inner and outer sides of the upper and lower jaw brackets on one side, and the half-side brackets are connected to the horizontal part of the bracket through a curved connecting rod 34, and the cross section is H-shaped;

[0072] The third situation of the back teeth toothbrush: For users with insensitive pharynx, little foreign body sensation and not easily nauseated, only one toothbrush is used to clean the back teeth of the whole mouth, which is referred to as a large toothbrush for full-mouth back teeth. The toothbrush is equivalent to the structure of the upper and lower halves of the back teeth toothbrush in the first situation connected together by a large U-shaped bracket 7, and is also equivalent to the structure of the left and right halves of the back teeth toothbrush in the second situation connected together by a large U-shaped bracket 7.

[0073] When cleaning the back teeth, in order to reduce the foreign body sensation, it is preferred to use a posterior toothbrush for two cleanings, one for the upper and lower posterior teeth on the left side and the other for the upper and lower posterior teeth on the right side. Or, clean the mandibular teeth and maxillary teeth separately.

[0074] Figure 4-1 It is a side view of a front toothbrush placed in a user's mouth. Figure 4-2It is a top view of the front toothbrush. The upper bristle cluster 32 is for brushing the maxillary teeth. The upper bristle cluster 32 is glued and fixed to the outer side 61 of the upper bracket and the inner side 51 of the upper bracket. The bristle cluster 32 is tilted upward, and the tip of the bristle cluster 32 is tilted upward, extending to the gingival sulcus 9, the neck of the tooth and the adjacent space of the maxillary teeth. The bristle cluster 32 is glued and fixed to the outer side 62 of the lower bracket and the inner side 52 of the lower bracket. The bristle cluster 32 is tilted downward, and the tip of the bristle cluster 32 extends to the gingival sulcus 9, the neck of the tooth 1 and the adjacent space of the lower teeth.

[0075] Humans have 28 permanent teeth (excluding wisdom teeth). Figure 7 8 shows the first situation of the back toothbrush. In order to reduce the foreign body sensation and prevent nausea, the bristle clusters 32 of the back toothbrush cover the left and right canines and all premolars and molars of the user's lower jaw, a total of 10 teeth. In this case, the user needs a total of 2 back toothbrushes and 1 front toothbrush to clean all teeth.

[0076] The bristle clusters 32 of the posterior teeth area can also cover multiple teeth of the posterior teeth area of ​​the upper and lower jaws on one side, for example, cleaning 10 teeth of the upper and lower jaws on the right side at the same time. This belongs to the second situation of the posterior toothbrush. In this case, the user needs a total of 2 posterior toothbrushes to clean the upper and lower jaw posterior teeth on the left side and the upper and lower jaw posterior teeth on the right side, and 1 front toothbrush to clean all teeth.

[0077] When the user's mouth opening is relatively large and the pharynx is not sensitive, it belongs to the third situation of back teeth toothbrush. You can use a full-mouth back teeth large toothbrush to brush your teeth, such as Fig. 9 As shown (since it is a side view, only the right side of the user is shown), the bristle clusters 32 in the posterior tooth area can also cover multiple teeth in the posterior tooth area of ​​the upper and lower jaws at the same time, so multiple teeth behind the upper and lower jaws, such as 20 teeth, can be cleaned at the same time. In this way, the user only needs 1 full-mouth posterior toothbrush and 1 front toothbrush to clean all teeth.

[0078] If the user has a particularly strong foreign body sensation, and the pharynx, tongue and upper palate are sensitive, the toothbrush can be divided into more small modules or units. Although several modules or units for action execution toothbrushes are mentioned in the above detailed description, this division is not mandatory. In fact, according to an embodiment of the present disclosure, the features and functions of the two modules or units described above are concretized in one module or unit. Conversely, the features and functions of one module or unit described above can be further divided to be concretized by multiple modules or units.

[0079] The shape of the limiting member 36 is adapted to the adjacent teeth. The side view may be, but is not limited to, a triangle, a trapezoid, etc., and is spaced a certain distance from the adjacent teeth. For people with normal tooth arrangement, the occlusal surface of the maxillary central incisor 39 and the cusps of the maxillary canines are both on the occlusal plane of the teeth, and the occlusal surface of the maxillary lateral incisor 40 is 0.5-1 mm away from the occlusal plane. Fig. 9 As shown, the plane above the U-shaped bracket 7 is made according to the occlusal plane of the maxillary teeth. The occlusal surface of the maxillary central incisor 39 and the cusps of the maxillary canines touch the plane above the U-shaped bracket 7, and the occlusal surface of the maxillary lateral incisor 40 is a certain distance away from the plane above the U-shaped bracket 7. Of course, the buccal cusps of the maxillary premolars and other teeth also touch the plane above the U-shaped bracket 7. Figure 4-1 As shown, when a limiting member 36 is provided on the occlusal surface of the maxillary lateral incisor 40 of the U-shaped large bracket 7, the height of the limiting member 36 is equal to the specific distance between the maxillary lateral incisor 40 of the user and the tooth occlusal plane, so that the occlusal surface of the maxillary lateral incisor 40 just touches the top of the U-shaped large bracket 7. On the one hand, it serves as a tooth alignment mark point for positioning the bracket; on the other hand, the limiting member 36 is in the shape of a right-angled trapezoid, one side of which is adapted to the shape of the central incisor, and the other side is adapted to the shape of the canine cusp, and the limiting member 36 is separated from the adjacent teeth, i.e., the mesial side of the canine and the distal side of the central incisor, by a certain distance. When brushing teeth with a toothbrush, the teeth lightly contact the U-shaped large bracket 7, the toothbrush vibrates and moves slightly in the horizontal direction. When the movement range is too large, the adjacent teeth will touch the limiting member 36 and prevent the movement of the toothbrush. Therefore, the limiting member 36 limits the large horizontal movement of the toothbrush. Figure 7 As shown, the limiting member 36 is arranged near the cusp 10 of the mandibular canine 43 of the U-shaped large bracket 7, and is triangular in side view, matching the shape of the canine, thereby limiting the excessive movement of the toothbrush.

[0080] Figure 5 is a cross-sectional illustration of an apparatus placed on the neck of a mandibular posterior tooth crown of a periodontal patient, i.e., along the Figure 1 Example diagram of the a-a' section. Figure 6 This is an example of a cross-sectional view of a personalized toothbrush placed on the root of a mandibular posterior tooth of a periodontal patient, i.e. Figure 1 Example of the b-b' section. Figure 5 and 6 As shown, the bristle cluster 32 covers the tooth neck 1 and the interproximal space of the tooth, and the bristles can clean Figure 1 The surface of the tooth between the a-a' section and the b-b' section.

[0081] like Figure 5 and 6 as well as Fig.13The bristle clusters 32, hose 33 and bracket 4 are shown in the figure, and the hose 33 is arranged between the bristle clusters 32. Pipelines are arranged inside the bracket 4 and the handle 13, and the end of the hose 33 is arranged at the periodontal pocket of the periodontitis patient or the gingival sulcus of the user. The other end of the hose 33 is connected to the bracket 4 and the cavity inside the handle 13, and then connected to the first liquid storage bottle 91 through the first water inlet 81, so as to flush and apply medicine to the periodontal pocket of the user with periodontitis or the gingival sulcus of the gingivitis patient;

[0082] The water spray port is arranged between the bristle clusters, the U-shaped large bracket, the outer side of the bracket and the inner side of the bracket, and is connected to the water path inside the bracket, and is connected to the water pump and the second liquid storage bottle 92 through the second water inlet 82; the first liquid storage bottle 91 can be filled with periodontitis special liquid medicine such as povidone iodine or hydrogen peroxide for periodontal pocket flushing and suction, and the first liquid storage bottle 91 can be filled with iodine glycerin for gingivitis or periodontitis medication. Since the pressure for flushing the periodontal tissue and applying the medication does not need to be too high, the user can squeeze the liquid storage bottle by hand (a water pump can also be used), so that the liquid medicine can enter the periodontal pocket through the cavity inside the bracket 4.

[0083] Since teeth are hard tissues, the crowns are covered by enamel, which is harder than bone tissue and has good wear resistance. The enamel at the neck of the tooth is very thin or even lacks enamel coverage. Some people expose their dentin in the oral cavity. On the one hand, the dentin is relatively low in hardness and not wear-resistant, so it is easy to wear and form wedge-shaped defects. On the other hand, the structure inside the dentin is connected to the pulp, so it is sensitive to cold and heat. The gums are soft tissues, so you must use a soft-bristled brush, otherwise the gums will shrink and bleed. Fig.10 As shown, the bristle clusters 32 in the dotted frame have a greater hardness and bristle diameter than those outside the dotted frame for cleaning the tooth neck 1 and massaging the gums 12, so as to better clean the tooth hard tissue and the brackets made of metal or ceramic materials. The bristle clusters 32 outside the dotted frame use softer bristles with a smaller diameter, and are rounded, etc., so as to massage the gums 12 without damaging the weak structures of the gums 12 and the tooth neck 1.

[0084] like Fig.10 As shown, when the user wears an orthodontic bracket 26 and an orthodontic archwire 28 for tooth correction, in clinical practice, the orthodontic bracket 26 is usually made of metal or ceramic. The orthodontic bracket 26 is bonded and fixed to the surface of the orthodontic patient's teeth (lip, buccal side or tongue, palate side) by the orthodontist, and the orthodontic archwire 28 passes through the center of the orthodontic bracket 26 and is fixed in the bracket. This example only shows a certain brand of orthodontic brackets, such as Fig.10 As shown, the personalized toothbrush of the device is arranged in the position where the bracket is provided, and the toothbrush holder is arranged in the shape of a bracket, and the bristle tufts 32 cover all surfaces of the orthodontic bracket 26, as shown in FIG. Fig.11As shown in the bristle cluster 32 in the upper and lower figures, at the groove 27 in the orthodontic bracket, the bristle cluster 32 is arranged along the long axis direction of the tooth (roughly in the crown-root direction), so that when the user brushes his teeth in a horizontal direction, the food residue and dental plaque in the groove can be better cleaned.

[0085] The orthodontic brackets and other corrective devices of the user who is equipped with the orthodontic brackets 26 may be changed, and the teeth of orthodontic patients continue to move, so the bristles or brackets are replaced as needed at regular intervals.

[0086] like Fig.11 As shown, when a user has a dental implant in his / her mouth, since the diameter of all implants 16 implanted in the jawbone is smaller than the crown, the buccal or lingual side of the crown will protrude significantly relative to the implant 16. Fig.11 The situation in which the buccal side of the crown protrudes from the implant 16 is shown, which is also a very common situation in dental implants. The double arrows between the dotted lines show the protruding crown, so a wedge-shaped bristle cluster 32 matching the crown neck is set on the buccal side of the tooth neck 1 to effectively clean the area between the crown of the implant 16 and the gum 12. The bristle cluster 32 of the neck of the dental implant is made of nylon + PBT and other materials. The bristles are finer in diameter, rounded at the tip, and softer. The bristles are single-clustered and high-density, which can more effectively clean the tooth neck 1, prevent peri-implantitis 16, and massage the gum 12 to promote the health of the gum 12.

[0087] The bristle cluster 32 uses extremely soft bristles and bristles with finer diameters, made of nylon or PBT, to brush the neck 1 of the implant or the sensitive area of ​​the user's teeth; the bristles used to brush the neck 1 of the natural teeth are softer bristles and bristles with finer diameters, made of nylon, TPR, or PP, and the bristle cluster 32 is rounded; the bristles used to brush the orthodontic bracket 26, the occlusal surface of the crown, and the area of ​​the crown close to the occlusal surface can use slightly harder bristles with slightly larger diameters, made of nylon, TPR, or PP.

[0088] Fig.12 The above picture shows a special case of dental implants. Because the patient's mouth opening is small, that is, he cannot open his mouth wide, the maxillary second molar is implanted slightly away from the tooth in front of it during the implant surgery. Therefore, an obvious protrusion is formed on the mesial side of the crown. The double arrows between the dotted lines show the protruding crown, that is, the crown has a relatively protruding crown on the mesial side. At the same time, because the diameter of implant 16 is smaller than the crown, the buccal side of the crown of implant 16 is also relatively protruding. Fig.12 As shown in the figure below, a bristle cluster 32 suitable for the dental implant is designed. For ease of display, it is shown in the form of a separate toothbrush. The bristle cluster 32 matches the shape of the dental implant. When in use, the toothbrush is placed on the neck of the dental implant and vibrated horizontally, repeatedly several times.

[0089] For users with extremely sensitive teeth, it is preferred to set water spray ports 83 between the bristle clusters 32 and on the bracket 4, and it is preferred to add anti-tooth sensitivity ingredients into the liquid storage bottle. For users with extremely sensitive teeth, doctors do not recommend using toothpaste for brushing teeth because toothpaste contains abrasives. Since the neck of the tooth and the occlusal surface of the tooth are the most frequently worn parts, Fig.15 As shown, a water spray port 83 can be provided between the bristle clusters 32 of the toothbrush (near the neck of the teeth) and on the bracket 4 (near the occlusal surface of the teeth). A bubble generating device is used to generate bubbles to provide micron and nano bubble water to the water inlet. Micro-nano bubbles burst when sprayed onto the tooth surface, forming a shear force, which can improve the cleaning effect and solve the problem that teeth are not easy to clean without toothpaste. Anti-sensitive ingredients containing sodium fluoride and strontium chloride can be added to the liquid storage bottle to desensitize the teeth while rinsing them to treat dentin hypersensitivity.

[0090] The toothbrush bracket 4, bristle cluster 32, and hose 33 can be manufactured by 3D printing followed by bonding or self-assembly printing.

[0091] The bristle cluster 32 can be implanted into the support using the traditional implantation process. The part of the support attached to the support can be fixed using a detachable adhesive structure (such as Velcro). When replacing the bristles, you only need to peel off or remove the bristles from the structure of the support, and then fix the support of the new bristle cluster 32 to the support through the adhesive structure. Therefore, when replacing the bristles, there is no need to repeatedly print the support 4, which saves costs.

[0092] Example 1

[0093] Embodiment 1 of the present utility model provides a method for positioning a toothbrush for cleaning and caring teeth.

[0094] The positioning can be determined by aligning the tooth landmarks with the landmarks on the bracket. Optical elements are provided on the handle 13 for positioning. Dual positioning by aligning facial landmarks and tooth landmarks can also be used.

[0095] When the user has normal teeth arrangement and a mark point is set on the toothbrush holder, and the tooth mark point is aligned with the mark point on the holder to determine the position, when cleaning the front teeth, the front toothbrush is used. The user looks in the mirror, holds the handle 13, opens the mouth, and puts the toothbrush into the oral cavity. The user observes through the mirror that the vertical protrusion 14 on the handle is aligned with the structure at the midline of the user's nose tip, philtrum, or glabella, such as Figure 4As shown, the toothbrush is gently placed between the upper and lower teeth. The user observes through the mirror that the tips of the canines of the upper and lower teeth on both sides of the user touch the U-shaped bracket 7, the tips of the mandibular canines 10 on the left and right sides face the mandibular canine marking points 11 on the left and right sides of the U-shaped bracket 7, and the tips of the maxillary canines 29 on the left and right sides face the maxillary canine marking points 30 on the left and right sides of the U-shaped bracket 7. At this time, the occlusal surface of the user's maxillary central incisor 39 touches the top of the U-shaped bracket 7, and the occlusal surface 15 of the mandibular central incisor also touches the bottom of the U-shaped bracket 7. When three marking points are touched at the same time, the device gives a sound prompt to accurately place them in place, and the user can start brushing his teeth.

[0096] In the case that the user has normal dental arrangement, and an optical element is provided on the handle 13 for positioning, dual positioning of facial landmarks and dental landmarks can be adopted. When cleaning the back teeth, use a back toothbrush, taking the example of cleaning the back teeth on both sides of the lower half of the mouth at the same time. The user holds the handle, opens his mouth, puts the toothbrush into the mouth, and the large U-shaped bracket 7 touches the top of the mandibular teeth. The user observes through the mirror that the vertical protrusion 14 on the handle is aligned with the structure at the midline of his nose, philtrum, or brow point, and the optical element on the handle 13 emits a light beam to illuminate at least three facial landmarks on the user's face, including the tip of the nose, the midpoint of the nose wing, the brow point, the bottom of the earlobe, and the midpoint of the tragus. At this time, the toothbrush is accurately in place. At this time, the user can also observe through the mirror that the tips of his mandibular canines lightly touch the large U-shaped bracket 7, such as Figure 7 As shown, the cusp tops 10 of the mandibular bilateral canines are facing the left and right marks 11 on the U-shaped large bracket 7, and the occlusal surface of the mandibular central incisor 15 will also lightly touch the U-shaped large bracket 7 of the toothbrush ( Figure 7 This is a side view, and the central incisor on the left is not shown. In addition, in order to show the structure of the toothbrush holder, etc., the teeth other than the central incisor and canine are not shown).

[0097] For people with normal occlusion, the occlusal surfaces of the central incisors on the left and right sides of the maxillary teeth, the cusps of the maxillary canines, the buccal cusps of the maxillary first premolars, the buccal and lingual cusps of the maxillary second premolars, and the buccal cusps of the maxillary first molars are on the same plane, called the occlusal plane. The maxillary lateral incisors 40 are 0.5-1mm away from this plane, and this plane is parallel to the line from the midpoint of the user's nose to the midpoint of the tragus. The occlusal surfaces of the central incisors on the left and right sides of the mandible, and the cusps of the mandibular canines 10 are basically arranged in a straight line.

[0098] According to the specific structure of the toothbrush, the toothbrush holder is provided with marking points, the number of which is greater than or equal to 3, and the marking points correspond to the occlusal surfaces of the central incisors on the left and right sides of the upper and lower jaws of the user, the cusps 10 of the upper and lower canines, the buccal canines of the maxillary first premolars, the buccal and lingual cusps of the maxillary second premolars, the first buccal cusp of the maxillary first molars, and the occlusal surface of the maxillary lateral incisor 40. For users with abnormal bite, other positions can also be selected as marking points. The marking points are used for the placement of the toothbrush holder to ensure that the bristle cluster 32 is placed at the neck of the tooth, the interproximal space, the gingival sulcus 9, or the position of the restoration or orthodontic treatment device. When at least three marking points on the holder are lightly touched at the same time, the device gives a sound prompt to indicate precise placement, achieving double positioning, and the user can start brushing his teeth.

[0099] Example 2

[0100] Embodiment 2 of the present invention provides a method for brushing teeth using a toothbrush for cleaning and caring for teeth.

[0101] When using a front toothbrush, Figure 4-1 As shown, after the toothbrush is in place, according to the requirements of the horizontal vibration part of the modified Bass brushing method, the toothbrush is driven to vibrate manually or by a motor 17 in the horizontal direction (such as Figure 4-2 The toothbrush 31 is moved back and forth in a short distance (as shown by the arrow) for 7-10 times. Due to the limitation of the limiting member 36, the horizontal movement distance will not be too large. At this time, the tooth neck 1, the adjacent gap and the gingival sulcus 9 are cleaned. Then the user opens his mouth and takes the toothbrush out of the oral cavity. At this time, the lower jaw moves downward (the upper jaw of the human body cannot move), and the bristle cluster 32 moves toward the crown direction of the mandibular teeth to brush the buccal and lingual sides of the mandibular teeth, while taking out the dirt under the horizontal vibration brush. Then the user holds the handle 13 and moves the toothbrush downward to dislocate the toothbrush from the teeth. At this time, the bristle cluster 32 moves downward (that is, moves toward the crown direction of the maxillary teeth), brushes the buccal and lingual sides of the maxillary teeth, while taking out the dirt under the horizontal vibration brush, thus meeting the requirements of the Bass brushing method.

[0102] Then, when using the back toothbrush, the first case of the back toothbrush is taken as an example. The back teeth on both sides of the lower half of the mouth are cleaned with the back toothbrush. The bristle clusters 32 of the back toothbrush cover the canines and all premolars and molars on the left and right sides of the user's lower jaw, a total of 10 teeth. Figure 7 , as shown in 8, after the toothbrush is in place, follow the requirements of the horizontal vibration method of the modified Bass brushing method, along Figure 7 and Figure 8 In the direction of the arrow, the short distance in the horizontal direction trembles 7-10 times. Due to the restriction of the restriction member 36 (such as Figure 7), the horizontal moving distance will not be too large, and the tooth neck 1 and adjacent gaps and gingival sulcus 9 of the mandibular posterior teeth are cleaned. Then the user opens his mouth, holds the handle 13 to lift the toothbrush, and takes the toothbrush out of the oral cavity. At this time, the bristle cluster 32 moves toward the crown direction of the mandibular teeth, brushes the buccal and lingual sides of the mandibular teeth, and at the same time brings out the dirt of horizontal vibration brushing, that is, meets the requirements of the Bass brushing method. Use the same method to clean the posterior teeth on both sides of the upper half of the mouth with the upper half of the mouth toothbrush. When cleaning the upper tooth surface, the water nozzle can be used to spray micro-nano bubbles for cleaning at the same time. The occlusal surface of the tooth can be cleaned using the water nozzle of the personalized toothbrush in combination with micro-nano bubbles, or it can be cleaned using an ordinary toothbrush with a handle 13.

[0103] When brushing the back teeth, in order to make the tongue more comfortable, use the upper and lower half brackets to clean the teeth on one side at the same time.

[0104] Example 3

[0105] Embodiment 3 of the present utility model provides a cleaning and care toothbrush for users who suffer from severe osteoarthritis, Parkinson's disease, etc. and cannot make horizontal slight tremor movements, or for people such as teenagers and children who cannot learn the Bass brushing method. Fig.14 As shown, an automatic motion device 35 can be installed in the handle 13: the automatic motion device 35 arranged in the handle 13 includes a motor 17 and two bevel gears 21, a crank 23, a metal connecting rod 19 and a sliding rod 20. The connecting rod 19 and the sliding rod 20 are hinged, which is realized by a pin 24 in the specific design.

[0106] The motor 17 moves and the direction is adjusted by the bevel gear 21 to make the crank 23 rotate, and then drives the slide bar 20 to extend along the connecting rod 19. Fig.14 The toothbrush head is connected to the output rod 25, and the output rod 25 is connected to the slide rod 20 to make reciprocating motion. Because the connecting rod 19 can only reciprocate along the direction of the arrow, when the handle 13 is provided with an automatic motion device 35, the tail of the handle 13 of the toothbrush in the front teeth area needs to be horizontally facing the right side of the user (the user is accustomed to using the right hand, such as Figure 4-2 When brushing the front teeth, Figure 4-2 As shown, the user holds the handle 13 and activates the switch on the handle 13, and the device can perform a short-distance horizontal reciprocating motion in the direction of the arrow, that is, the horizontal direction.

[0107] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the utility model should be included in the scope of protection of the claims of the utility model.
