JP 2004/188070 of 08/07/2004 discloses an interdental brush holder for easy brush change and tilting of the brush. The holder is formed by the head part A, the holder part B and the cap part C. The head part A is connected to the holder part B releasably. The head part A comprises an interdental brush and a connecting part for connection to the holder part B. The holder part B comprises a body and a rotator rotatably mounted to the body. The body and the rotator are bevelled at the contact ends at an angle of 45 ° to their axis and the surfaces thus formed are the contact surfaces of the body and the rotator abutting in each rotational position of the rotator relative to the body. By rotating the rotator to which the brush head portion A is attached, the tilt of the brush relative to the body of the holder portion B changes so that their axes form a right angle or obtuse angle or a straight angle (90-180 °).

- EP 1741406 of January 10, 2007 relates to an interdental brush holder for interdental care with a replaceable brush comprising a motor holder for automatic rotation of the brush, and a brush part. The brush part is connected to the holder part releasably. The brush part can be connected to the holder part directly or via an adapter. In the case of direct connection, the brush forms an obtuse angle with the holder part. In the case of an adapter connection, the axes clamp

Also the obtuse angle, the size of which is given by the bend of the adapter at the end intended to attach the brush part.

Said shapes and construction of the interdental brush holders allow cleaning of the interdental spaces in the vestibulo-oral direction, from the outside of the teeth through the interdental slit to the inside of the teeth in the oral cavity.

The shapes and construction of the brackets allow insertion of the interdental brush into the space in the upper jaw 15-14-13-12-11-21-22-23-24-25 (all interdental spaces between upper teeth ranging from the right second upper premolar to the left in the lower jaw 35-34-33-32-31-41-42-43-44-45 (all interdental spaces between the lower teeth ranging from the left second lower premolar to the right second lower premolar). By tilting the brush holder, the outside of the teeth in the above-mentioned interdental spaces is properly cleaned. However, the inside of the teeth in these interdental spaces is not properly cleaned because the brush straightens through the interdental slot and no longer has the desired tilt on the inside of the teeth as on the outside.

When cleaning the interdental spaces in the upper jaw 18-17, 17-16, 16-15, 25-26, 26-27, 27-28 (all interdental spaces between the teeth ranging from the right third upper molar to the right second upper premolar and in the range of the left second upper premolar to the left third upper molar) and in the lower jaw of the interdental spaces 38-37, 37-36, 36-35, 45-46, 46-47, 47-48 (all interdental spaces between the teeth ranging from left third lower molar to the left second lower premolar and within the range of the right second lower premolar to the right third lower molar), including all third molars distally, the core of the interdental brush formed by the wire must be manually differently shaped and directed to clean the interdental space.

Said shapes and designs of the holders requiring the need to manually shape the core of the interdental brushes formed by the wire are ineffective. There is insufficient cleaning of the interdental spaces due to poor insertion of the interdental brush. The toothbrush is not inserted in the correct line of the interdental spaces, causing repeated attempts to insert the interdental brush. In the aforementioned shaping of the interdental brush core, due to the bends of the metal structure of the interdental brush core, the brush bristles are spaced and thus the metal interdental brush core can come into contact with the teeth, neck and gums. Continuous shaping and bending of the interdental brush core creates the risk of breakage and increases the risk of injury in the oral cavity. Also tooth spacing can lead to tooth abrasion.

Insufficient hygiene of interdental spaces affects plaque retention, trapping of microorganisms (bacteria) and eventually the formation of tartar. Tartar is formed primarily on the inside of the teeth, which can be difficult to clean properly with the help of interdental brush holders of the given shapes and construction. This can cause tooth damage, gingivitis and periodontitis.

In the two-sided version of the holder, when brushes are attached to the holder from both sides of the holders, it is also unhygienic to place the holder in commonly used cups or glasses. The holder stands in a cup or glass on a fixed interdental brush. It rests on the bottom of cups or glasses, where dirt and bacteria are deposited by placing additional interdental brush holders and toothbrushes, often wet after brushing the teeth. Bacteria and impurities are trapped on the interdental brush and thus get into the oral cavity during cleaning.

The object of the invention is to propose a new design of the interdental brush holder so as to allow proper cleaning of the inner teeth at the interdental spaces and further insertion of the interdental brush into all interdental spaces in the jaw without requiring manual shaping of the interdental brush core.

SUMMARY OF THE INVENTION

This object is achieved by an interdental brush holder for cleaning interdental spaces having a V-shaped or open U shape with unequal long arms, wherein at the end of the shorter arm means for securing the interdental brush are arranged so that the axis of the interdental brush lies substantially in extension of the shorter arm according to the invention, which is characterized in that the arms form an acute angle α.

An advantage of the design of the holder according to the invention is that it allows a progressive method of cleaning the interdental spaces with an interdental brush facing out of the oral cavity outward, orally or in the oral cavity. When inserting the interdental brush from the sublingual and palatal landscape from the oral cavity to the outside of the teeth, the supragingival and subgingival coating (plaque and then the tartar) is well removed from the outside and inside of the teeth. gingivitis and periodontitis. The holder according to the invention further enables cleaning of the interdental spaces of all teeth in the upper and lower jaws without the necessity of manually shaping the interdental brush core for certain groups of interdental spaces. Furthermore, a visual inspection of the treatment is possible since, while holding the holder according to the invention, the hands are outside the area of view of the interdental brush.

For optimum cleaning of the interdental spaces, an acute angle α of <45 ° is preferred for the U-shaped holder.

For optimum cleaning of the interdental spaces, a sharp angle α of 10 to 45 ° is preferred for the V-shaped holder.

According to a preferred embodiment, the holder has means for detachably attaching the interdental brush. When the interdental brush is worn or damaged, only the interdental brush is replaced, the holder remains the original one.

According to a preferred embodiment, the interdental brush fastening means comprise an external threaded clamping head and with brush receiving grooves. On the clamping head there is a screw-on union nut to secure the interdental brush.

This makes it possible to use the holder for several types of CURAPROX ©, Oral-B © and Steam Swiss © interdental brushes. The CURAPROX © interdental brushes are fastened in the head by snapping them into the groove and can be additionally secured with a union nut.

According to a preferred embodiment, a further shorter arm and means for attaching another interdental brush are provided at the free end of the longer arm.

This results in a double-sided holder allowing simultaneous attachment of two interdental brushes. In the case of dental care with several interdental brushes, e.g. of different size, it is not necessary to replace the brushes in the holder as often as with a one-sided holder. This has the advantage of reducing the time spent attaching the interdental brushes to the holder and reducing the wear rate of the fastening means on the holder and on the brushes.

The double-sided holder also allows to have at one end of the holder an embodiment of the arms according to the invention for cleaning the interdental spaces with a brush from the oral cavity outwards, and

In the double-sided version of the holder, when brushes are attached to the holder from both sides of the holders, the holder set in commonly used pots or glasses rests on their bottom with parts of the holder and not with an interdental brush. This will not trap dirt and bacteria on the brush

The bottom of the cups or glasses.

According to a preferred embodiment, the longer arm comprises at least two detachably joined parts. The disconnected holder takes up less space, which is advantageous eg when packing the holder when traveling. Another advantage is the universal use of the holder as one-sided and two-sided.

To increase the grip strength of the holder, the longer arm includes a grip non-slip piece.
