Definitions
- the invention relates to a toothbrush according to the preamble of Such a toothbrush is known from US 4,608,968 A.
- interdental toothbrushes are unsuitable when it comes to cleaning the teeth of fixed braces, because the length and rigidity of the axis mean that they cannot get under the retaining straps.
- the internal metal pin is very annoying and uncomfortable when it comes into contact with the tooth.
- the "fir trees" are usually guided at right angles to the vertical surface of the teeth, the end of the wire pin, if it hits the tooth or gums, can cause injuries here.
- DE-PS 435 355 a toothbrush is known, the outer bristles of which protrude beyond the edge of the brush head. In contrast to the subject of the application, however, the bristles are inserted on the side of the brush head. Furthermore, this toothbrush is used in a different way than the subject of the application.
- DE 297 11 700 U1 discloses a brush which is also very flat, but which has bristles standing vertically upwards and does not have the other design features of the object of the application.
- No. 5,345,647 A shows a possibility of using the bristles starting from the center of the bristle head outwards at an increasing angle, so that the outer bristles protrude beyond the edge of the brush head.
- this toothbrush is a conventional size brush.
- the brush head shown is only similar in cross section to the application, but does not have any features of the object of the application.
- DE41 25 168 A1 shows a toothbrush with a round, removable brush head which, however, in contrast to the application, has bristles standing vertically.
- the last four inventions differ in both Size as well as in the type of application very clearly from Subject Matter. They are for normal tooth brushing use provided and not for a special cleaning of stuck Braces and interdental spaces.
- the invention has for its object to provide a means that especially with fixed braces in the area of the bonded Platelets and also in other hard to reach places in the mouth enables optimal cleaning of the teeth.
- the bristles are in on a brush head concentric circles or semicircles arranged and in from the inside outwardly increasing angles to the vertical of the brush head inclined outwards, the inner circle having an inclination angle of approx. 10 ° and the outer angle of inclination of approx. 45 ° to the vertical of the brush head and thus the outer bristles over the edge of the brush head protrude (Fig. 1 and 2).
- the brush head shows a lot small dimensions (diameter approx. 5 mm, total height approx. 4 - 6mm).
- each bristle circle in relation to the previous in is inclined outwards at an acute angle of approx. 10 ° and thus V-shaped openings are created between the rows of bristles good absorption of the plaque guaranteed (Fig. 2).
- the small brush head enables easy access under the Tethers of the tooth adjustment device without the tethers bend and due to the shortness of the bristles it becomes longer bristles Usual, "approximate” sliding away avoided and the desired positions are reached precisely. (Fig. 4)
- a further embodiment of the invention is possible according to claims 3 and 4, namely that the brush head and handle consist of one piece and the brush head is disc-shaped or tongue-shaped, has a length of approximately 8 mm and a width or diameter of approximately 5 mm (Fig. 6 and 7).
- This embodiment also has the advantages of the arrangement and brevity of the bristles specified in claim 1, but may have the advantage over the interchangeable brush head (claim 2) that the one-piece production is cheaper.
- This version could also be designed for single use (or a maximum of 3-4 times). Since an elaborately designed handle is not necessary for this purpose of use, this could be shorter and thinner than with ordinary toothbrushes.
- Another possible application of the invention lies in its general use (also for people without fixed braces) for cleaning the interdental spaces, on the gum line and all places difficult to access e.g. Tooth inside (tongue side) (Fig. 5) in addition to normal dental care with conventional toothbrushes. Again, it is known that some with normal toothbrushes Places in the mouth can hardly be reached.
- the invention combines several possible uses in one: Except for cleaning the teeth of stuck braces and the Interdental spaces make them effective at the same time Cleaning the teeth in the area of the gum line and at the Inner side of the tooth (tongue side).
- toothbrushes according to the invention according to claim 1 can described areas can be cleaned well and comfortably. This can Dental plaque removed and tartar permanently avoided.
- the manual application allows (in contrast to electrically operated Rotary toothbrushes) a turning in any direction, as well as a Adjust the pressure to the individual sensitivity.
- the recommended tooth brushing time of three minutes is the rarest Cases complied with.
- the present invention is suitable according to the Brushing your teeth still leftovers in the places caused by the normal toothbrush cannot be reached as well.

Description
Bei den handelsüblichen normalen Zahnbürsten gleiten die relativ langen Borsten über die Winkel hinweg und somit wird nur ein "ungefähres" und mehr dem Zufall überlassenes Reinigen erreicht.
Des weiteren existieren Wasserstrahl-Zahnduschen, die zwar grobe Speisereste jedoch keinen Zahnbelag entfernen, und auf die deshalb im weiteren Verlauf nicht weiter eingegangen wird.
Vom Benutzen der elektrischen Rotationszahnbürste raten die Kieferorthopäden dringend ab, da sich dabei die Drähte der Haltevorrichtung verbiegen können und somit der erfolgreiche Fortschritt der kieferorthopädsichen Behandlung zumindest unterbrochen ist.
Zudem wird der innenliegende Metallstift bei Berührung mit dem Zahn als sehr störend und unangenehm empfunden. Die "Tannenbäumchen" werden gewöhnlich im rechten Winkel zur senkrechten Fläche der Zähne geführt, wobei das Ende des Drahtstiftes, wenn es auf Zahn oder Zahnfleisch trifft, hier Verletzungen verursachen kann.
Aus DE 297 11 700 U1 ist eine ebenfalls sehr flach gestaltete Bürste bekannt, die jedoch senkrecht nach oben stehendc Borsten trägt und auch nicht die übrigen Gestaltungsmerkmale des Anmeldungsgegenstands aufweist.
DE41 25 168 A1 zeigt eine Zahnbürste mit rundem, abnehmbarem Bürstenkopf, der jedoch, im Gegensatz zur Anmeldung senkrecht stehende Borsten trägt.
Diese Ausführung weist ebenfalls die Vorzüge der im Patentanspruch 1 angegebenen Anordnung und Kürze der Borsten auf, hat jedoch gegenüber dem austauschbaren Bürstenkopf (Patentanspruch 2) möglicherweise den Vorteil, daß die einstückige Herstellung preiswerter ist. Auch diese Ausführung könnte eventuell für den Einmal-Gebrauch (oder maximal 3 - 4maligen Gebrauch) ausgelegt sein. Da für diesen Zweck der Anwendung ein aufwendig gestalteter Griff nicht nötig ist, könnte dieser kürzer und dünner als bei gewöhnlichen Zahnbürsten sein.
