Definitions

  • the invention relates to a toothbrush for manual or mechanical actuation.
  • Optimal oral hygiene means removing existing dental plaque (microbial plaque) and food residues and preventing these pathogenic plaque.
  • a pleasing increase in oral hygiene awareness is increasingly offset by well-intentioned, but primarily too force-intensive brushing measures, which are increasingly frightening damage on a scale of acute and chronic brush trauma: exposed tooth necks (gingival recessions), puncture injuries caused by toothbrush bristles in the gums (acute brushing lesions), gaps in the breasts (breast formation) Gaps), wedge-shaped loss of substance in the area of the root near the crown of the tooth (wedge-shaped defects), whereby the rate of loss of tooth substance can be increased by the usual increasing consumption of acidic food and beverages with subsequent brushing measures (erosions).
  • the invention is therefore based on the object of creating a toothbrush which enables the user to achieve the optimum contact pressure for brushing teeth in a simple manner without additional electrical or electronic aids.
  • the brush shaft is formed at a suitable point with a special profile cross section, which allows a preferably sudden mechanical deflection of the brush head when reaching a certain contact pressure, the prerequisite is created in a particularly simple and advantageous manner for the brushing force applied by the patient only up to a specified maximum limit to take effect. If this maximum limit is reached, it deforms beforehand curved deflection profile of the brush shaft suddenly becomes an elongated profile with a correspondingly changed stiffness, the characteristic of this change in stiffness being variable within wide limits due to the curvature, the material properties and the material thickness of the deflection profile. With a thin, strongly arched profile cross section, high forces can be achieved up to the deformation limit with subsequent greatly reduced transmission possibilities.
  • the deflection profile of the brush shaft is formed only with a slight curvature but with a larger profile cross section, this effect is weakened so that every transfer characteristic of the brushing force can be achieved by varying the curvature, the profile cross section and / or the material used. It is also possible to provide the transmission characteristic with different levels by coupling two or more different deflection profiles, e.g. to reach two "sticking points" with different forces. This makes it easy to display a contact pressure that is too low or too high with any desired bandwidth.
  • Toothbrushes with this technological innovation are to be widespread among patients, especially among young adults; Because epidemiological studies on a representative number of 18 to 22 year old young people prove that they can be enticed into force-intensive brushing by a commitment to dental health that is in itself to be welcomed, and that damage is set at a significantly higher rate compared to the same age groups decades ago . These new toothbrushes therefore serve an etiological purpose oriented and therefore successful dentistry, save the patient expensive operations to cover exposed tooth necks with dubious long-term success and help to reduce costs.
  • the brush shaft 1 in a deflection section 2 following the brush head 3 is in each case similar over part of its length to a leaf spring according to the crack frog principle formed that an optimal or maximum contact pressure can not be exceeded when brushing teeth until the brush head 3 is deflected.
  • the brush head 3 is arranged on the brush shaft 1 so that it is suddenly deflected when a certain contact pressure is reached so that an optimal contact pressure can be maintained during brushing.
  • the mechanical deflection or the audible exceeding of the sticking point in the deflecting section 2 of the brush shaft 1 designed according to the click frog principle thus provides an acoustic and / or tactile display when the optimum contact pressure on the brush shaft is reached.
  • FIGS. 3 to 5 Various examples of suitable deflection profiles 4 on the brush shaft 1 are shown in FIGS. 3 to 5, in each case in accordance with the section lines III-III of FIGS. 1 and 2.
  • FIG. 3 shows a deflection profile 4 which is curved approximately in the shape of an arc in the transverse direction to its longitudinal extent Transition area between brush head 3 and brush shaft 1.
  • two profile strips 4a, 4b running in the longitudinal direction of the brush shaft 1 are angled relative to one another approximately in accordance with the curvature of the deflection profile 4 of FIG. 3 and are advantageously separated from one another in this way by a central longitudinal slot 4c, that when the contact pressure is exceeded, as well as the curved deflection profile 4 of FIG. 3, they come into a common stretched position transversely to the longitudinal extent of the brush shaft 1, so that the brush head 3, as indicated in FIGS.
  • the third exemplary embodiment shown in FIG. 5 for the deflection profile 4 between the brush shaft 1 and the brush head 3 has a corrugated shape transversely to the longitudinal extension of the brush shaft 1, but functions practically in the same way as that described above in connection with the two exemplary embodiments of FIGS. 3 and 4 has been set out.
  • the thickness of the material cross-section and the curvature or the inclination of the legs 4a, 4b of the deflection profile 4 play an important role for determining the optimal or maximum contact pressure, but can be selected and shaped as required.
  • Brush shaft 1, brush head 3 and deflection section 2 can each be formed in one piece from a suitable plastic or composite material with corresponding suspension properties.
  • two different profile cross sections 4 corresponding to FIGS. 3 and 4 or 5 can be connected in succession such that the brush head 3 relative to the brush shaft 1 in the pressure-relieved initial position of FIG. 6 is angled below in order to use a sufficient optimal contact pressure to reach the extended intermediate position shown in FIG. 7 after overcoming a first sticking point and, if this optimum contact pressure is exceeded after overcoming a second sticking point, to bend upward into the third deflection position shown in FIG. 8, in which the brush head 3 relative to the longitudinal axis of the brush shaft 1 is angled upward similarly to the two exemplary embodiments of FIGS. 1 and 2 and is in an unstable position in which brushing teeth is no longer possible.
