Description

The invention relates to a device and a method for cleaning teeth and to a method for producing a tooth covering suitable for this purpose.

Tooth decay is a civilization disease of the teeth, which can lead to complete destruction of the affected tooth if not treated. Origin and progression of caries are subject to different factors. The most important of these include the presence of a biofilm (including, for example, bacteria) on the tooth surface and the steady supply of substrates (in particular of sugar contained in foods). In particular, by supplying such a substrate, it can lead to the formation of an acidic environment within the biofilm, which can lead to the dissolution of hard tooth substance.

The most important protective measures against caries and other tooth-damaging diseases or effects include the mechanical removal of the biofilm from the tooth surface with the aid of a toothbrush. In known methods, the biofilm can be released by a movement of plastic bristles over the tooth surface. To facilitate electric toothbrushes have been proposed in known approaches in which a movement is transmitted from an electric motor to bristles.

A disadvantage of using a manual toothbrush, whether electrical or purely mechanical, is the dependence of the cleaning effect on the skill of the cleaning person. Especially people with disabilities, the elderly and children often have significant difficulties with dental care. In general, in particular tooth surfaces that are far within the oral cavity and thus are not or only poorly visible, can be achieved worse by a toothbrush and therefore tend to have a more pronounced biofilm. This can be reflected in caries. In addition, incorrect use of a toothbrush can damage the gum adjacent to a tooth and / or other areas of the oral cavity.

In other known approaches, the teeth cleaning is to be simplified with the aid of sound waves. Here are vibrations that z. B. can be generated by a transducer, transmitted to the tooth surfaces. These vibrations should lead to the detachment of the biofilm. Nevertheless, it is also necessary here to guide the transfer device (eg the brush head) as precisely as possible over the tooth surfaces.

On this basis, it is an object of the present invention to solve the problems described in connection with the prior art or at least alleviate. In particular, a tooth cleaning set, a method for producing a tooth sheath usable therein, and a method for cleaning teeth will be presented.

These objects are achieved with a tooth cleaning set and a method for cleaning teeth according to the features of the independent claims. Further advantageous embodiments of the device and the method are specified in the dependent claims. The features listed individually in the claims can be combined with one another in any technologically meaningful manner and can be supplemented by explanatory facts from the description, wherein further embodiments of the invention are shown.

• - mindestens eine Zahnumhüllung zur zumindest teilweisen Umhüllung mindestens eines Zahns, wobei die mindestens eine Zahnumhüllung eine zum Zahn gerichtete Innenseite und eine der Innenseite gegenüberliegende Außenseite aufweist, und
• - mindestens eine Vibrationseinheit,

wobei die mindestens eine Zahnumhüllung und die mindestens eine Vibrationseinheit über eine Verbindung lösbar miteinander verbindbar sind.Contributes to this a tooth cleaning set, comprising at least:

• - At least one tooth covering for at least partially wrapping at least one tooth, wherein the at least one tooth sheath has an inner side facing the tooth and an inner side opposite the outer side, and
• at least one vibration unit,

wherein the at least one tooth sheath and the at least one vibration unit are detachably connectable to one another via a connection.

The tooth cleaning set is designed to clean teeth and is particularly suitable for use by people with disabilities, the elderly or children. The invention is not limited to use in humans. Also an application in animals is possible.

The tooth sheath is preferably a plastic foil or a sheath made of a similar material for the teeth. Preferably, the tooth covering is rigid, so that vibrations lossless or almost lossless can be transmitted from this. The material used preferably meets hygiene requirements resulting from applicability in the mouth. The at least one tooth sheath is preferably at least partially adapted to at least one tooth or its outer shape, in particular such that a gap between the at least one tooth sheath and the at least one tooth preferably has a substantially equal (small) extent. This gap should, for example, 15 times the Do not exceed the material thickness of the tooth sheath. It could be particularly advantageous that the expansion of the intermediate space at most points or even at any point of the at least one tooth sheath amounts to a maximum of 5 mm [millimeters]. The extent of the gap at a point of the at least one tooth sheath is to be understood as the shortest distance of this point from the tooth surface of the nearest tooth. The at least one tooth sheath is preferably designed such that it covers the entire visible area of one or more teeth. The person skilled in the art understands that, in particular, areas of the tooth within the gum are not enveloped by the tooth covering. It is preferred that a single tooth cover completely envelopes all the teeth (of a jaw) together, in particular all of the teeth (of a jaw). Alternatively, it is preferred that a plurality of tooth envelopes are provided, which in their entirety envelop all the teeth, in particular all the teeth completely. In particular, it is preferred that a tooth sheath is provided which completely envelops all the teeth of the lower jaw and a further tooth sheath which completely envelopes all the teeth of the upper jaw.

The vibration unit is adapted to generate vibrations by means of a vibration generator, via which the tooth covering can be excited. The vibrations are preferably ultrasound. In that case, the vibration unit preferably comprises an ultrasound generator, which in particular can be designed as a sound transducer. The sound transducer is preferably designed and configured to convert electrical energy into ultrasonic vibrations. Preferably, ultrasound is used at a frequency in the range of 10 kHz to 50 kHz [kilohertz], in particular from 20 kHz to 30 kHz. Furthermore, it is preferred that the frequency of the vibrations can be regulated, in particular by adjustment by the user and / or by an automatic recognition of an operating state of the vibration unit. For example, by means of an electronic control in dependence on a determined with a sensor measured variable such. B. a vibration amplitude, automatic control of the ultrasonic frequency. Alternatively, the ultrasound frequency can be varied electronically controlled over time, e.g. B. in the form of a preset cleaning program.

In order to ensure a particularly good coupling of vibrations (and in particular ultrasound) into the tooth sheath, the tooth sheath can be brought into direct contact with the vibration unit. This is preferably done manually by pressing the vibration unit to the tooth sheath. It is preferred that the vibration unit is guided and / or fixable on the tooth casing in such a way that a desired vibration coupling point (for coupling the vibrations) to the tooth casing is simply "hit" in the mouth and / or slipped off the tooth casing during the treatment can be avoided. Slipping is to be understood as a deviation from a preferred vibration coupling point. Such fixing can be ensured in particular when the connection z. As a magnetic connection, a click connection, a hook closure, a push-button connection or a positive connection pocket connection.

The solubility of the compound is easier to use and also allows an individual replacement of the tooth cover. For example, a single vibration unit may be used by multiple users in conjunction with their own dental wraps. Preferably, vibrations (and in particular ultrasonic waves) are uniformly transmitted to the tooth surfaces. For this reason in particular, it is preferred that the gap between the tooth sheath and the tooth surfaces has substantially the same extent over the entire extent of the tooth covering, as described above. In addition, it is preferred that the tooth sheath has a thickness that is predominantly or even constant over the entire extent of the tooth sheath. In this case, the thickness of the tooth covering is to be understood as meaning a material thickness of the material enveloping the teeth.

In one embodiment of the tooth-cleaning set, the inside of the at least one tooth covering has at least one structural element. It should be clarified here that the at least one structural element is not to be imaged by a shape of the at least one tooth, ie does not form a "negative" of the tooth surface. Rather, the at least one structural element is designed so that it bridges the gap, which is otherwise set essentially the same way, locally.

The at least one structural element is preferably a rib, knob, shaft, lamella or the like, which is preferably formed with a plastic. With the at least one structural element, which is moved during treatment or the use of the vibration unit on / on the tooth surface, a particularly good tooth cleaning effect can be ensured. Under the tooth cleaning effect is to be understood in particular that a biofilm is broken by a abrasive effect on the tooth surfaces and / or removed from them.

It is particularly preferred that the structural elements are arranged distributed over the entire inner side of the tooth covering (uniformly or non-uniformly). This can be a Teeth cleaning effect can be achieved for all teeth. The at least one structural element is preferably dimensioned such that it bridges the gap between the tooth sheath and the tooth in such a way that the structural element is in contact with the tooth. It is preferred that the structural element is pressed with a pressure on the tooth. As a result, a particularly good tooth cleaning effect can be ensured. The pressure can be generated by pressing the tooth covering or the at least one structural element in the manner of an interference fit against the tooth. An interference fit of two elements is provided if these two elements at least partially in touching contact with each other (ie have a distance of zero) and this contact contact is supported by a force pressing the two elements against each other. The force required for a press fit is preferably generated manually, ie the vibration unit is preferably pressed manually against the tooth casing.

The at least one structural element can be obtained in particular by a plasma method for surface modification. With such a method, in particular a plastic surface (such as here the inside of the at least one tooth sheath) can be modified such that the plastic surface receives a structure.

In one embodiment of the tooth cleaning set, the inside of the at least one tooth sheath has at least one brush.

The at least one brush preferably comprises a plurality of bristles, the z. B. can also be used in a toothbrush. The bristles are preferably at least partially formed with a plastic. The at least one brush may be one of the structural elements described above and / or may be provided in addition to further of the structural elements described above. The bristles can be arranged on one of the structural elements. Preferably, a plurality of bristles are arranged uniformly over the entire inner side or distributed, so that the bristles in their entirety constitute a brush. Alternatively, it is preferable that the inside has a plurality of spatially separated brushes each comprising a plurality of bristles. The bristles of the individual brushes can differ in their length, orientation, distribution and density (that is, the number of bristles per surface). This ensures a particularly good tooth cleaning effect for all teeth. The totality of the brushes preferably comprises an area of at least 50%, in particular at least 80%, of the inside of the tooth covering. Analogous to what has been described above for the at least one structural element, it is preferred for the at least one brush to be pressed against the tooth by a pressure in the manner of an interference fit. The bristles preferably have a length that is suitable to bridge the gap between the tooth covering and the tooth. Preferably, the bristles are added in the tooth coating process in such a way that the bristles (in particular in the case of a plastic tooth cover) are connected to the material of the tooth covering by a surface modification. Furthermore, it is preferred that at least one brush has bristles aligned in such a way that a part of the gum adjacent to the tooth can be cleaned therewith.

In a further embodiment of the tooth cleaning set, the inside of the at least one tooth sheath has a rougher surface than the outside of the at least one tooth sheath.

It is preferable that the tooth sheath has a roughness on the inner side facing the teeth, which can enhance a cleaning effect of the teeth. Preferably, the inside of the tooth covering is made bristle-like. The surface roughness of the inner side can be achieved or reinforced in particular by the structural elements described above, in particular by the bristles.

In a further embodiment of the tooth cleaning set, the at least one tooth sheath is at least partially formed with a plastic.

The plastic is preferably a polyethylene, in particular a polyethylene terephthalate (also known by the abbreviation PET). In particular, it is preferred that the plastic is biocompatible, which means in particular that the plastic is suitable for use in the oral cavity and meets the corresponding hygienic requirements. It is preferred that the plastic used be soft enough to avoid injury to the gums or other areas of the oral cavity. Furthermore, it is preferred that the plastic is transparent. Thus, the placement of the tooth covering on the teeth can be facilitated and the cleaning success can be controlled. For a good durability of the tooth coating, it is preferred that the plastic is not attacked by water and other substances present in the teeth cleaning. In particular, it is preferred that no components of the plastic used, in particular no harmful constituents, are released from it by the action of such a substance, and that no parts of the tooth sheath detach from it. In addition to the plastic tooth coating may include other ingredients.

In a further embodiment of the tooth cleaning set, the connection is designed as a magnet holder.

The magnet holder is preferably realized in that at least one metallic plate is provided on each of the at least one tooth sheath and on the vibration unit, wherein at least one of two metallic plates to be connected in pairs is made permanently magnetic. The other one can be magnetically passive (in particular paramagnetic). In particular, iron or an iron alloy is suitable for these metallic platelets. Preferably, the magnetic holder or the metallic plates are protected against corrosion. This can be z. B. be realized in the form of a sheath made of a plastic, but also in that the metallic platelets are embedded in the material of the tooth covering or the vibration unit. The at least one metallic plate on the tooth sheath constitutes a preferred vibration coupling point at which the vibration unit is preferably brought into contact with the tooth sheath. In this case, the magnetic holder can cause the vibration coupling point, in particular due to a magnetic attraction, can be found more easily, and that the vibration unit can be fixed in the vibration coupling point.

In a further embodiment of the tooth cleaning set, the at least one vibration unit has at least one handle, a vibration generator and a connecting part. The connecting part comprises a vibration coupling point or a connecting element for forming the connection.

Preferably, the vibration generator of the vibration unit is integrated in the handle. In particular, it is preferred that the vibration generator is designed as an ultrasound generator. The connecting part is preferably a longitudinally executed part, in particular a rod which extends from the handle and thus allows a connection with the tooth sheath located in a mouth. For this purpose, the connecting part is preferably dimensioned accordingly. Furthermore, it is preferred that the connecting part is releasably connectable to the vibration unit. Thus, for a multi-user shared vibration unit to improve sanitation, each user can use his own connector. The connecting element is preferably one of the metallic magnetic connection plates described above. Preferably, the vibration unit is battery operated, in particular by a rechargeable battery. Furthermore, it is preferable that the vibration unit is made waterproof as a whole. The shape of the handle is preferably substantially cylindrical.

The particular advantages and design features described for the tooth cleaning set described are applicable and transferable in any technologically meaningful manner to the described method for producing a dental covering.

The production of the impression in step a) preferably takes place using a substance which adapts to the shape of the teeth and then hardens quickly. Step a) can be carried out in particular by a dentist or a qualified specialist. From the impression, which is a negative of the teeth, a tooth model is produced in step b). This can be done, for example, by filling the impression with plaster. In step c), the tooth model produced in step b) is preferably used. The tooth sheath is preferably produced in step c) by adapting a suitable material to the shape of the teeth (or the tooth model). It is preferred that the material is first deformable and dimensionally stable after the manufacturing process. The deformability can in particular by substances such. As plasticizers can be achieved, which volatilize in the manufacturing process, in particular by heating. It is particularly preferred that the tooth sheath is formed with a plastic.

It is possible that the impression in step a) is generated by a digital method. For this purpose, for example, a camera and / or a 3D scanner can be used whose data are converted by software in step b) a digitally existing tooth model. From the digitally available tooth model thus obtained, a real tooth model can be obtained, for example by a three-dimensional printing method, which can then be used in step c) as described above. Alternatively, however, the tooth covering in step c) can be obtained directly from the digitally existing tooth model.

The vibration coupling point is preferably designed as one of the connections described above, in particular as the magnet holder. In particular, it is preferred that the vibration coupling point is one of the metallic platelets described above.
