Definitions
- Toothbrush bristles are usually traumatic on teeth and gums, though being quite effective against the dental plaque, causing micro-lesions on the dental enamel whereon more plaque adheres. In a long-term while this fact causes gengivitis and irreversible damages to the dental structure.
- toothbrushes employ very hard bristles made of syntetic or natural material in order to have a sufficient consistency.
- toothbrushes presenting a non-traditional shape have bristles obtained by an injection moulding; however, because of their shape and scarce efficiency, they produce more damages than the traditional ones. Furthermore, they have less effective action on the bacteric plaque, not allowing the adequate movement required by the specific dental structure (each person has different needs according to his/her own problems), and also because the bristles (generally shorter than the traditional ones) of these toothbrushes damage the gums with their low flexibility.
- the prior art bristles are not anti-traumatic and multifunctional as claimed for those of the invention described in the following.
- multifunctional bristle means that said bristle simultaneously effects several actions. In particular, this is obtained by giving to said bristle a suitable shape.
- the anti-traumatic multifunctional bristle object of the present invention is characterized by the fact that it presents a step structure, wherein said step structure can consist of a plurality of cylinders or frustums of cone.
- a head e.g. an extractable head
- the bristles according to the present invention can be made of a hydro-repellent material, e. g. polyethylene or similar by-products, or gummy material, or silicone rubber.
- the claimed bristles can be built up by means of an injection moulding process.
- figure 1 shows a side view of a first embodiment of the bristle object of the present invention
- figure 2 shows a top view of the bristle of figure 1
- figure 3 shows a side view of a second embodiment of the bristle object of the present invention
- figure k shows a top view of the bristle of figure 3
- figure 5 shows an extractable head for toothbrush using a plurality of bristles according to the first embodiment shown in figures 1 and 2.
- anti-traumatic multifunctional bristle used in the present specification refers to the shape and the consistency of said bristle due to the use of non-traumatic materials, such as polyethylene or similar by-products having low or high density.
- the first embodiment shown in figures 1, 2 refers to a bristle composed of a plurality of cylinders having different diametres
- bristle 10 consists of a plurality of cylinders 11, 12,
- Figures 3. 4 show a second embodiment of the present invention, wherein the bristle 20 consists of a plurality of frustums of cone 21, 22 , 23. Likewise, the larger the distance fro ⁇ the base 2k , the smaller the cone diameters.
- the bristles according to the present invention can be made of a hydro-repellent material, e. g. polyethylene or similar by-products, or gummy material, or silicone rubber.
- the claimed bristles can be built up by means of an injection moulding process.
- a very important aspect, which is different from the traditional bristles, is due to the fact that the user can determine the hardness of the bristle section to be used by more or less pressing the bristles against the cleaning part. Thus, bristles having a controlled action can be obtained. It is obvious that the thin top section of the bristle does not traumatize the gums by performing the gingival massage.
- Elastic action it depends on the material; the bristles generally return to the starting position after the action.
- Vibrating action the bristles are disposed so that, moving together, they vibrate on the part to be cleaned.
- Sussultatory action the bristles present a concentric cylindrical or frusto-conical shape; therefore, each section slightly jumps when the toothbrush glides on the teeth or on the gums, thus creating a sussultatory movement.
- Re-sussultatory action during the gliding on the part to be cleaned, the lower part of the concentric frustums of cone having greater consistency creates a further stronger sussultatory movement which can be defined a "re-sussultatory action”.
- Sliding and removal action it depends on the kind of material and is based on the principle that when two bodies scrape on each other, the harder removes the softer. It should be noted that the used material is harder than the plaque and softer than the dental enamel, i.e. it is different from traditional bristles, which are harder than plaque, dental enamel and gums.
- FIG. 5 shows an extractable head 100 consisting of a main body 30 which supports a plurality of bristles 10 (in this figure the bristles 10 are partially deformed) . Inside the main body 30 a cavity 40 is provided in order to receive the handle (not shown) of the toothbrush. The plurality of bristles 10 and the main body 30 can be obtained with only one moulding operation.
