Abstract
Abstract The present invention relates to an orthodontic toothbrush, particularly for children wearing regulating pins, characterized by a brushing head (30) comprising on the one hand two lateral and longitudinal groups of tufts of bristles (31,35), each group possessing tufts (32,36) inclined towards the outside of the brushing head and diverging relative to a median longitudinal plane of the head, and tufts (33,37) converging towards this median longitudinal plane, and secondly at least one central longitudinal row of shorter tufts (40) parallel to the median longitudinal plane.

Orthodontic toothbrush, particularly for children wearing regulating pins, characterized by a brushing head (30) comprising on the one hand two lateral and longitudinal groups of tufts of bristles (31,35), each group possessing tufts (32,36) inclined towards the outside of the brushing head and diverging relative to a median longitudinal plane (P) of the head, and tufts (33,37) converging towards this median longitudinal plane (P), and secondly at least one central longitudinal row of shorter tufts (40) parallel to the median longitudinal plane (P).
Claim 2
Dependent Claim
83 words
Orthodontic toothbrush, particularly for children wearing regulating pins, characterized by a brushing head (30) comprising on the one hand two lateral and longitudinal groups of tufts of bristles (31,35), each group possessing tufts (32,36) inclined towards the outside of the brushing head and diverging relative to a median longitudinal plane (P) of the head, and tufts (33,37) converging towards this median longitudinal plane (P), and secondly at least one central longitudinal row of shorter tufts (40) parallel to the median longitudinal plane (P).
Claim 3
Dependent Claim
39 words
Toothbrush according to claim 1, characterized in that the difference in length between the bristles of the lateral groups (31,35) and the bristles of the central row (40) is substantially equal to the thickness of the regulating pins (V).
Claim 4
Dependent Claim
35 words
Toothbrush according to claim 1 characterized in that the difference in length between the bristles of the lateral groups (31,35) and the bristles of the central row (40) is of the order of 2 mm.
Claim 5
Dependent Claim
44 words
Toothbrush according to claim 1 characterized in that the axes of all the tufts (32,36, 33,37,40) are contained within transverse planes perpendicular to the said median longitudinal plane (P) and to the mean plane of the surface (39) of the head bearing the tufts.
Claim 6
Dependent Claim
41 words
Toothbrush according to claim 1 characterized in that each lateral group of tufts (31, 35) comprises two longitudinal rows of tufts (32,36; 33, and 37) which diverge and converge respectively relative to the median longitudinal plane (P) of the brushing head.
Claim 7
Dependent Claim
38 words
Toothbrush according to claim 1 characterized in that the inclination (x,y) of the tufts of the lateral groups (31,35) relative to the median longitudinal plane (P) is between 5° and 30° and preferably of the order of 10°.
Claim 8
Dependent Claim
34 words
Toothbrush acccrding to claim 1 characterized in that the end (23) of the handle (20) opposite to the brushing head (30) is designed to carry, in a removable fashion, accessories (50,60) for dental hygiene.
Claim 9
Dependent Claim
33 words
Toothbrush according to claim 7, characterized in that the end (23) of the handle (20) opposite to the brushing head (30) is designed to carry, in a removable fashion, an interdental brush (60).
Claim 10
Dependent Claim
35 words
Toothbrush according to claim 7, characterized in that the end (23) of the handle (20) opposite to the brushing head (30) is designed to carry, in a removable fashion, a support for dental floss (70).
Claim 11
Dependent Claim
91 words
Orthodontic toothbrush, in particular for children wearing regulating pins, according to claim 1, characterized by a brushing head (30) possessing, first, two lateral and longitudinal groups of tufts of bristles (31,35), each group being formed of two longitudinal rows of tufts (32,36; 33,37) which diverge and converge respectively relative to the median longitudinal plane (P) of the brushing head, the tufts of these lateral rows being implanted in staggered lines to intersect, and secondly a central longitudinal row of tufts of shorter bristles (40) parallel to the median longitudinal plane (P).
