Definitions

  • the invention relates to an interdental brush, wherein filaments (or bristles) between two twisted wire sections are held.
  • filaments or bristles
  • interdental brushes exist in the Essentially from two twisted thin pieces of wire, between which the bristles or synthetic filaments are clamped. While earlier the wire ends of the small Brushes had to be inserted into a handle by the user (see US 4,222,143, Tarrson), modern interdental brushes have a plastic part which is under control can be conveniently used (see, for example, EP 0 001 044 A1, Georg, EP 0 203 082 B1, Curaden AG). Depending on the width of the interdental spaces large or small brushes are needed. It Therefore, there are a number of brushes with different wire and bristle diameters .. There are already known systems which give the patient a simple and enable fast determination of the correct interdental brush (cf., for example, EP 0 892 625 B1, Curaden AG).
  • the object of the invention is a belonging to the aforementioned technical field Interdental brush to create, which also with small diameter of the wire is stable.
  • the twisted wire sections have a diameter of 0.3 mm or less and consist of a nickel-free or nickel-poor steel.
  • nickel-free or nickel-poor steel is referred to in the context of the invention, a steel, if the nickel content in the alloy is less than 0.05% by weight.
  • Interdental brushes according to the invention are characterized by increased rigidity and an improved restoring force. If the brushes z. B. obliquely in the Between teeth are introduced and abut with the tip, then the twisted section will not deform so easily, or if it deforms, he is not so easily deformed permanently. This allows the properties of particular thin brushes are noticeably improved for the user. With the use nickel-free wire also increases the body compatibility of the brush without any protective coatings are necessary.
  • the wire used has a diameter of 0.15 mm or more. Practical experiments have shown that in the smallest common today interdental brushes with 0.15 mm to 0.30 can be worked well. Thick wires result naturally more stable brushes than thin ones. Under certain circumstances, it is advantageous if the Wires should not be chosen as thick as possible. Thinner wires lead to more flexible To brush. A preferred wire diameter is in the range of 0.18 - 0.27 mm.
  • the wire used preferably has a tensile strength of 1000 N / mm 2 or more. In most cases, the tensile strength does not have to be greater than 1200 N / mm2. Such Wires not only give a brush with low risk of breakage, but also allow a processing in fast-working and strongly bending machines. Too high Strength can make processing more difficult because the wires can break. Surprisingly was found that the inventive wires even then can be processed if they have a tensile strength of 1000 N / mm2 and more to have. This is not the case with the nickel-containing wires.
  • the wires are made of an austenite.
  • the robustness of the filament carrier, which through the twisted wires is formed so that it is favorably influenced.
  • by the corrosion resistance ensured that long-stored or broken brushes (because in the meantime occurred corrosion) in use not to problems for the user to lead.
  • Stretching or twisting wires during processing in the brush production increases the tensile strength.
  • the processed wires are opposite the raw state to a certain extent stiffer.
  • interdental brush In the automated and automated production of an interdental brush are in known manner between two wire sections filaments introduced and the wire sections twisted with the filaments.
  • the wire sections may be formed by the two halves of a single piece of wire per se. You can but also be realized with two separate wires.
  • Fig. 1 shows how the wire sections 1a, 1b are twisted together.
  • the filaments are not shown in FIG. 1. They are clamped between the two wire sections 1a, 1b. It is recognizable that the wire sections 1a, 1b are bent relatively strong. They form, so to speak the filament carrier.
  • Fig. 2 shows a cross section through the filament support.
  • the wire sections 1a, 1b have a certain diameter D. Between them, the filaments 2 are held.
  • the Diameter D is set so that on the one hand the filament support a desired stiffness and on the other hand, the interdental brush has a certain degree of mobility is adjusted.
  • the mobility may be e.g. be determined by a probe, as they are is known from the aforementioned EP 0 892 625 B1.
  • For the usability are under the diameter D as well as the width B and the wire material used (or its flexibility) relevant.
  • Interdental brushes made of nickel-free steel (nickel-free in this context: nickel content below 0.05% by weight) of the following composition were successfully produced (rounded weights, impurities not mentioned): 17% by weight chrome 14% by weight manganese 2% by weight molybdenum 0.5% by weight nitrogen 0.25% by weight silicon 0.11% by weight carbon 0.04% by weight nickel 0.02% by weight phosphorus 0.006% by weight titanium rest iron
  • the wire had a diameter of 0.23 mm and a tensile strength of at least 1100 N / mm2 and at most 1300 N / mm2. Further attempts were made with a wire made with 0.27 mm diameter and same alloy. The tensile strength was at least 1000 N / mm2 and at most 1200 N / mm2.
  • the interdental brush fitted with the new wire holds one under rotating curvature three times more frequent exposure to the traditional brush. (In the so-called. rotating the plastic part is clamped and the tip of the brush is with a device rotates circularly.)
  • the above alloy composition can be varied. Cr and Mn content may e.g. be changed by 3% by weight. If the biocompatibility is particularly important, the Ni content is preferably chosen lower.
