i Detailed description of the invention The term "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 s;ri 1 ~r 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 In lo particular, bristle 10 consists of a plurality of cylinders 11, 12, 13. The larger the distance from the base 14, the ~ ~lle~ the cylinder diameter.
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 from the base 24, the smaller the cone diameters.
In these two embodiments it is not the single bristle which works, but each concentric section of the bristle itself.
In addition to the superimposed cylinders or frustums of cone, rollFhn~ses, and/or various edges, and/or various rulings, and/or irregular geometrical shapes, and/or a rectangular or triangular shape, and/or at least one threaded screw (not shown in the alleged fi~ures) can be provided.
, The bristles according to the present invention can be made of a hydro-repellent material, e. g. polyethylene or si lAr by-products, or gummy material, or silicone rubber. The cl Ai ~ bristles can be built up by means of an injection moulding process.
W O ~ /xl PCTAEP95/03830 _ 4 _ 2201 360 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 cle~n; ng 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 ~ CsAEe. Therefore, if the user exerts less pressure, he does not traumatize the gums, whereas traditional bristles traumatize them even by a simple ski nE because of their hardness.
The tidy bristle disposition as well as their special material, e.g.
water-repellent polyethylene, allow a better cleaning of the toothbrush, e. g. with a treatment with hot water for 3 minutes. A
further advantage of the bristle is due to the elasticity of the used materials.
Sa~d bristles are multifunctional due to the following simultaneous actions:
1) Elastic action : it depends on the material; the bristles generally return to the starting position after the action.
2) Vibrating action : the bristles are disposed so that, moving together, they vibrate on the part to be ~1 e~ned .

Sa~d bristles are multifunctional due to the following simultaneous actions:
1) Elastic action : it depends on the material; the bristles generally return to the starting position after the action.
2) Vibrating action : the bristles are disposed so that, moving together, they vibrate on the part to be ~1 e~ned .
3) 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.
4) Re-sussultatory action : during the gl;~i ng on the part to be ~le~n~, the lower part of the concentric frustums of cone having greater consistency creates a further stronger sussultatory -v ~ t W 096/09781 PCT~EP95/03830 2 ~ 01 3 60 ' which can be defined a "re-sussultatory action".
5) Sl ;~;ng 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 differen~ from traditional bristles, which are harder than plaque, dental enamel and gums.
Only one of the aforesaid actions is nowadays used, i.e. the removal action due to the bristle consistency, but not to its shape, which is smooth. Therefore, if said bristles have to be effective, they must be very hard and. as a consequence of this fact, very traumatizing.
Figure 5 shows an extractable head lOO consisting of a main body 30 which supports a plurality of bristles lO (in this figure the bristles 10 are partially deformed). Inside the main body 30 a cavity 40 is lS provided in order to receive the h~n~l e (not shown) of the toothbrush.
The plurality of bristles lO and the main body 30 can be obtained with only one moulding operation.
It should be understood that several modifications may be made in the specific form of the invention shown in the drawings and described above without deviating from the broader aspects of the invention.
