Die Erfindung bezieht sich auf ein Zahnreinigungsgerät.The invention relates to a tooth cleaning device.
Zur Erlangung einer ausreichenden Mundhygiene sind eine Reihe von verschiedenartigen Geräten bekannt, die an den Zähnen und am Parodontium (Zahnhalteapparat) wirksam werden. Derartige Geräte sollen die Kariesgefahr verringern, sowie der Gefahr von Parodontitis vorbeugen.To achieve adequate oral hygiene, a number of different devices are known that work on the teeth and the periodontium (periodontal ligament). Such devices are intended to reduce the risk of tooth decay and prevent the risk of periodontitis.
Die Zahnbürste gilt hier als das bekannteste und am häufigsten verwendete Gerät. Bekannt sind aber auch Geräte, die neben Borsten auch federnd-elastische Werkstoffe am Kopf eines Handstückes aufweisen, oder ganz auf Borsten verzichten. Der Verzicht auf Borsten soll die dadurch möglichen Abrasionsschaden am Zahnschmelz oder Dentin verhindern und Zahnfleischläsionen ausschließen.The toothbrush is the best known and most frequently used device. However, devices are also known that have not only bristles but also springy-elastic materials on the head of a handle, or that do not have bristles at all. The omission of bristles is intended to prevent the possible abrasion damage to the tooth enamel or dentin and to prevent gum lesions.
Bei der Verwendung von Arbeitsteilen, die ausschließlich aus federndelastischen, schaumstoffart igen Werkstoffen bestehen, soll die Reinigungswirkung durch eine besondere Ausgestaltung der Oberfläche erfolgen, wie z.B. Noppen, Kegel, Rillen. Diese Ausführungsart kann zwar, falls weich genug, eine Zahnfleischmassage bewirken, allerdings ist der Reinigungseffekt unzureichend.When using working parts that consist exclusively of spring-elastic, foam-like materials, the cleaning effect should be achieved by a special design of the surface, such as knobs, cones, grooves. This type of design can, if soft enough, massage the gums, but the cleaning effect is insufficient.
Der Grund liegt darin, daß der Schaumstoff sich schwammartig mit Flüssigkeit aufsaugt, durch den ausgeübten Druck bei der Zahnreinigung die Flüssigkeit dann aber wieder teilweise ausgepreßt wird. Adhesionskräfte im Inneren des Schaumstoffes führen nun dazu, daß die komprimierten Form des Schaumstofffes beibehalten wird, bis die Flüssigkeit langsam verdunstet ist. Im nassen, komprimierten Zustand verliert der Schaumstoff aber die Elastizität und Formanpassungsfähigkeit, wodurch die Reinigungswirkung vermindert wird. Darüberhinaus gelangen Schmutzpartikel, Bakterien und Viren ins Innere eines saugfähigen Schaumstoffes, die sich nur schwer entfernen oder abtöten lassen.The reason is that the foam absorbs liquid like a sponge, but the pressure exerted when cleaning teeth causes the liquid to be partially squeezed out again. Adhesive forces inside the foam mean that the compressed shape of the foam is maintained until the liquid slowly evaporates. When wet and compressed, however, the foam loses its elasticity and ability to adapt to its shape, which reduces the cleaning effect. In addition, dirt particles, bacteria and viruses get into the interior of an absorbent foam and are difficult to remove or kill.
Ziel der Erfindung ist, die bekannten Probleme der Zahnabrasion und Zahnfleischläsion durch die Zahnbürste und deren Borsten zu verringern bzw. zu unterbinden, andererseits die Probleme von weichen, saugfähigen Schwämmen, steifen Vließen o.a. zu verhindern, sowie die Putzwirkung insgesamt zu verbessern.The aim of the invention is to reduce or prevent the known problems of tooth abrasion and gum damage caused by the toothbrush and its bristles, and on the other hand to prevent the problems caused by soft, absorbent sponges, stiff fleeces, etc., and to improve the overall cleaning effect.

(Blatt 2 von 2) Description
(Page 2 of 2)
Nach Anspruch 1 wird die Säuberung des Zahnes mit Hilfe eines synthetischen, elastischen Schaumstoffes durchgeführt, dessen Kammern im Inneren allseits geschlossen sind. Dadurch ist das Einsaugen von Wasser und Speichel in das Innere nicht möglich. Somit können auch Schmutzkörper oder Bakterien und Viren nicht eindringen und sich festsetzen (Abb.l). According to claim 1, the cleaning of the tooth is carried out with the help of a synthetic, elastic foam whose chambers are closed on all sides. This means that water and saliva cannot be sucked into the interior. This also means that dirt particles or bacteria and viruses cannot penetrate and settle (Fig. 1).
Auf diese Weise treten auch keine zusätzlichen adhesiven Kräfte im Inneren des Schaumstoffes auf, die seine Elastizität negativ beeinträchtigen. In this way, no additional adhesive forces occur inside the foam, which could negatively affect its elasticity.
Durch die an der Oberfläche halboffenen 0,2-0,4 mm kleinen Hohlräume, wird die Zahnpasta auf die Zahnoberfläche gepresst und auf dieser verschoben. In diesem Mikrobereich eingeschlossene Schmutzkörper werden miterfaßt und vom Substrat gelöst (Abb.l).Through the half-open 0.2-0.4 mm cavities on the surface, the toothpaste is pressed onto the tooth surface and moved along it. Dirt particles trapped in this micro area are also captured and released from the substrate (Fig. 1).
Die Putzwirkung nach Anspruch 1 erfolgt also im Gegensatz zu den bekannten Reinigungsgeräten, primär nicht durch scheuernde und abrasive Borsten oder Fasern, sondern hauptsächlich durch die Putzwirkung der Zahnpasta selbst, wobei die Wirkung der Inhaltstoffe, wie z.B. Schlemmkreide, Schaumbildner, Fluoride usw.,vervielfacht wird.In contrast to the known cleaning devices, the cleaning effect according to claim 1 is not primarily achieved by scouring and abrasive bristles or fibers, but mainly by the cleaning effect of the toothpaste itself, whereby the effect of the ingredients, such as chalk, foaming agents, fluorides, etc., is multiplied.
Nach Anspruch 2 darf der Kreisdurchmesser der Kurvatur der groben Oberflächenstruktur, gebildet z.B. durch Pyramiden, Kegel Zapfen, Rillen u.a., nicht unter 1 mm liegen. Auf diese Weise werden die an den Spitzen und Winkeln auftretenden Spannungen bei der Reinigungsbewegung soweit begrenzt, daß ein Einreißen des Schaumstoffes verhindert wird (Abb.2). &Lgr; According to claim 2, the circular diameter of the curvature of the coarse surface structure, formed eg by pyramids, cones, tenons, grooves etc., must not be less than 1 mm. In this way, the tensions occurring at the tips and angles during the cleaning movement are limited to such an extent that tearing of the foam is prevented (Fig. 2). &Lgr;
Nach Anspruch 3. erhält der Kopf des Haltestückes eine Aussparung (Abb.3). durch die der Schaumstoff (Arbeitsteil) unter Kompression eingeführt werden kann (Abb.4). Der Vorteil dieser Ausführung liegt darin, daß eine besondere Befestigung des federnd-elastischen Schaumstoffes am Kopf nicht weiter notwendig ist, da durch die entstehende Presswirkung an den Kopf eine ausreichende Retention des Schaumstoffes erreicht wird. Diese Konstruktion erlaubt eine Putzmöglichkeit an zwei Flächen und ein sehr einfaches Auswechseln des Arbeitsteiles. Das vereinfachte Herstellungsverfahren bietet einen weiteren Vorteil. According to claim 3, the head of the holding piece has a recess (Fig. 3) through which the foam (working part) can be inserted under compression (Fig. 4). The advantage of this design is that a special fastening of the springy-elastic foam to the head is no longer necessary, since the resulting pressing effect on the head ensures sufficient retention of the foam. This design allows cleaning on two surfaces and very easy replacement of the working part. The simplified manufacturing process offers another advantage.
