Description

Tooth cleaner

Technical Field

The application relates to the technical field of cleaning tools, in particular to a tooth cleaner.

Background

With the development and progress of society, people gradually recognize that dental health is a basic guarantee of physical health, and dental health problems are mostly caused by dental plaque, and the most effective way to remove dental plaque is tooth brushing. From the earliest people to clean the oral cavity through gargling and developing the application of the toothbrush, the sound wave electric toothbrush applied on a large scale until now has more and more emphasis on cleaning the oral cavity, more and more means and better effects.

However, the existing tooth cleaning technology cannot fundamentally solve some problems, such as that a certain training skill is required for brushing teeth with a common toothbrush, the cleaning effect is mainly dependent on the brushing skill and strength of an individual, otherwise, the effect, such as the relative angle of the toothbrush head and teeth (optimal angle is 45 °), the cleaning time and the toothbrush head position, have an influence on the cleaning effect.

Taking the current mainstream electric toothbrushes in the market as an example, the cleaning time is 2 minutes, the cleaning time of each group of teeth surface is 30 seconds, the 30 seconds are uniformly distributed to each tooth, and the cleaning is also performed aiming at the gum and the tooth gap, so that the operation difficulty is high.

Meanwhile, the grinding teeth are positioned in the deep part of the oral cavity, and the cleaning difficulty is higher than that of the incisors and the cuspids, so that the common toothbrush and the electric toothbrush are difficult to clean in place.

There is therefore a need in the art to develop a technique that can facilitate the overall cleaning of all teeth.

Detailed Description

The technical scheme in the application is further described in detail below with reference to the accompanying drawings.

The application discloses a tooth cleaner, which is based on the principle that according to the digitized three-dimensional data of the dentition of a customized person, a three-dimensional design software is used for designing a dental floss which is completely matched with the shape of the dental floss, and then a mould or a 3D printing mode is used for manufacturing a soft dental floss cleaning tool which is designed.

When in use, the tooth cleaner can be smeared with the friction agent and then sleeved on the oral cavity teeth, and the tooth cleaner is contacted and rubbed with the surface of each tooth in all directions through the natural repeated occlusion action of a person. The tooth cleaner can clean all tooth surfaces quickly and thoroughly under the action of the abrasive agent.

Referring to fig. 1, the main body of the tooth cleaner disclosed in the present application is an arc-shaped flexible dental floss 1, and the arc-shaped flexible dental floss 1 is arc-shaped and has two planes and two arc-shaped side surfaces, wherein for convenience of description, the two planes are respectively referred to as a first surface 12 and a second surface 13, and the two arc-shaped side surfaces are respectively referred to as an inner side surface 14 and an outer side surface 15.

With reference to the oral cavity, the first surface 12 is located in the oral cavity near the upper gum, the second surface 13 is located in the oral cavity near the lower gum, the inner side 14 is located on the lingual side, and the outer side 15 is opposite to the inner side.

The first surface 12 and the second surface 13 on the arc-shaped flexible dental socket 1 are respectively provided with a sinking area 11, the bottom of each sinking area 11 is connected and provided with a group of dental cavities 2, the dental cavities 2 are positioned in the arc-shaped flexible dental socket 1, and the top ends of the dental cavities are connected with the bottom of the sinking area 11.

The dentition cavity 2 serves to envelop the teeth, the sinking region 11 serves to envelop the gums at the root of the teeth, and the purpose of the envelop is to clean the tooth surface and the gums.

Referring to fig. 2 and 3, each group of dentition cavities 2 includes a plurality of cleaning cavities 21 arranged in sequence, the cleaning cavities 21 including a bottom surface 211 and two side surfaces 212, adjacent cleaning cavities 21 in the same group being in communication.

Taking a specific cleaning process as an example, a user first applies a quantity of abrasive to the inner wall of the sinking region 11 and the inner wall of the dentition cavity 2, and then places the arc-shaped flexible dental floss 1 into the oral cavity, with the arc-shaped flexible dental floss 1 between the upper and lower gums.

The user then bites down, causing the teeth on the upper and lower beds to enter the two sets of dentition chambers 2, respectively, where each tooth of the user enters the corresponding cleaning chamber 21.

The tooth cleaner disclosed by the application designs the cleaning cavity 2 which is completely matched with the tooth cleaner in form by using three-dimensional design software according to the digital three-dimensional data of the dentition of a user, and then adopts a mould or 3D printing mode to manufacture the designed soft tooth socket cleaning tool. The digitized three-dimensional data of the dentition of the user can be obtained directly by adopting an intraoral three-dimensional scanner or can be obtained by turning out the plaster dentition after the model is bitten by a custom and then obtaining the data by a desk type three-dimensional scanner.

The tooth cleaner provided by the application has the following advantages:

the cleaning effect is better, can carry out the omnidirectional contact to each tooth in user's oral cavity, can carry out comprehensive cleaning to tooth surface, is difficult for producing omission and dead angle.

The cleaning process is longer, for example, two minutes is taken as an example, the toothbrush heads of the common toothbrushes and the electric toothbrushes have limited volumes, and two minutes are required to be uniformly distributed to each tooth, and the tooth cleaner provided by the application can continuously clean the tooth surface in two minutes or shorten the cleaning time, for example, forty seconds or one minute.

A targeted design is possible, for example, in the case of uneven tooth arrangement, the inner wall of the cleaning chamber 21 can be more closely adjacent to the tooth surface at the shade or gap, and the tooth surface can be cleaned by continuous friction.

Referring to fig. 4, in some examples, a first cleaning protrusion 22 is added at the interface of the dentition cavity 2 and the bottom surface of the sinking region 11, and the first cleaning protrusion 22 is present on each side 212 of the cleaning cavity 21. The first cleaning protrusions 22 function to clean residues at gums.

It will be appreciated that the teeth will have residues in the gums, etc., and that the teeth will be difficult to clean when the toothbrush is moved up and down, especially residues in the gums, etc., and the cleaning difficulty is greater. To solve this problem, the present application uses the first cleaning protrusions 22 to clean the residues of objects and the like in the gums, and specifically the first cleaning protrusions 22 apply a force to the gums to expose the root portions of the teeth when the teeth are moved relative to the first cleaning protrusions 22.

So that the residues of objects etc. in the gingiva can be transferred to the outside of the gingiva during the tooth cleaning process.

The shape of the first cleaning protrusions 22 is matched with the edge of the side surface 212 away from the bottom surface 211, that is, the shape of the gums of the user, so that a better cleaning effect can be obtained.

In some possible implementations, the diameter of the first cleaning projection 22 is controlled to be 0.5mm to 2mm, and the size is limited in order to avoid damage to gums while obtaining a better cleaning effect.

Referring to fig. 4, in some examples, there is a second cleaning projection 23 between the two sides 212, where the second cleaning projection 23 may also be considered to be between the two cleaning chambers 21. The second cleaning projection 23 serves to clean the crevices of the teeth.

The cleaning chamber 21 has two sides 212, on each of which there is one second cleaning projection 23.

In some possible implementations, the height (H in fig. 5) of the second cleaning protrusion 23 is 1mm-2mm, and the size is limited so that the second cleaning protrusion 23 can not be blocked at the tooth gap during the process of moving the second cleaning protrusion 23 relative to the tooth on the premise of obtaining better cleaning effect, so that the tooth cleaning process can be smoothly performed.

In some possible implementations, the height of the second cleaning projection 23 (H in fig. 5) tends to decrease in a direction approaching the bottom surface 211, and the maximum height of the second cleaning projection 23 is 1mm to 2mm.

In some examples, the hardness of the portion of the arc-shaped flexible dental floss 1 at the side surface 212 is greater than the hardness of the portion at the bottom surface 211, and the hardness of the portion at the side surface 212 is greater, so that a better supporting effect can be obtained; the hardness of the portion at the bottom surface 211 is small, and the user's upper teeth and lower teeth can feel more comfortable when they are in contact with the bottom surface 211 of the cleaning chamber 21.

In some examples, the thinnest thickness of the arc-shaped flexible dental floss 1 is not less than 2mm while preventing biting and breakage while ensuring rigidity.

In order to ensure good friction and movement space, the fit distance between the dentition cavity 2 and the tooth surface is designed to be-2 mm to 2mm. The data acquisition mode of the tooth cleaner is mentioned in the foregoing, and after the data is acquired, the matching distance between the dentition cavity 2 and the tooth surface can be designed to be-2 mm to 2mm by increasing or decreasing the whole data.

It will be appreciated that since it is necessary to fill with a abrasive such as toothpaste during normal use, the abrasive fills the gap between the cleaning cavity 21 and the teeth and acts to frictionally clean the tooth surfaces during movement. The matching mode mainly considers that the friction force is required to be increased under certain special conditions, such as the removal of mild calculus, and the aim of increasing the friction force is fulfilled by a tight matching mode. In addition, the cleaner is made of a material with certain elasticity, so that the problem of overtightening cannot occur.

When the cleaner is engaged, the cleaner moves unidirectionally along with the upper teeth or the lower teeth, and the cleaner needs to be held by hands and consciously and upwardly or downwardly apply proper force, so that the lower teeth or the upper teeth are respectively cleaned.

The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
